FUCK YEAH! Go hard, go early and drill port it. Please don't forget the Ramflo filter for that extra 10% Ooooooohhhhh this is gonna be fun. I cant wait to see the looks on the Barries faces next time the bonnets open at the southland A&P and classic car show etc

Ohhhhh shucks Glad I am entertaining ya.

Is a suitably good enough reason to post up threads for me too. Otherwise we'll be there in our retirement homes wondering why the fuck we aint retired in the Maldives on a yacht like those other lucky fuckers. Because we fucked with old car holes for money is why.... But it is fun.

Here I go, late Saturday night and another installment. Because that's how I party... I thought I'd post up a pic of all the other bits safely tucked away on my beautifully arranged 'Honda Goldwing cylinder head apartment storage facilities. At the right height to peer at when needed (maybe for a mojo boost one day - "oh yeah.. that's what the rest of the engine looked like before I pulled it apart, chopped it up and started a whole can of worms type project from it") Here's a piston storage rack that would make Maclarens factory effort look like something from scrapheap challenge.. Carefully laid out heads- these engines have identical heads, cam carriers, cams etc for each side. Don't mix them up!.. All covered up by a lovely sheet so not to get covered in dust. (It makes it like a secret stash of engine goodness).. Now back to the block/engine casings. I'll call it a block from now on, ignoring the fact its two halves. So I have now got to re-mount the oil pump on the opposite side, higher up and turned 180 degrees from where it was originally mounted. It has to go about here... I also had to work out a new way of getting the oil from this new position to the oil filter and then onwards to the starting point of the main oil gallery. Here's a lovely picture you can ponder over. Best pondered with some strong coffee... The standard oil filter location. This is on what was the front of the engine but is now the back and right where I wanted to put a cross member to hold the engine up. Not to mention a big chunk of that lower half of the casing has disappeared after I chopped it off, right through the original oil filter centre line... So that had to go. I looked over the engine and eventually worked out a spot that would suit a new filter pedestal to be mounted so allowing easy access for filter removal. It also had potential to allow for a Mazda style oil cooler or a take off plate to suit a normal oil cooler. It was going to mount roughly about here... It was going to require a big hefty lump of alloy to start with. But I was on lockdown along with most of NZ. Luckily the local engineering workshop that I go to for many bits of random steel stock was doing 'essential' jobs for some industries still running. The workshop foreman left me a lump of alloy in his letterbox that happened to be on the way home from the supermarket shop. This was a lucky thing! Here's the lump of alloy after a lot of it was turned into many many little tiny shards of alloy... I'll get back to that lump later. Next thing was make some flat areas that I could mount things on and line stuff up with. The block was split in two luckily I was able to clamp it to the bed of the mill. I machined the inside so... I had to do this on both sides in different areas. One side had to be machined to suit a new location for the oil pump. On the other casing i machined out pockets to take machine bits that would locate new oil pump feed and return pipes. I was going to do oil the pipe work in alloy using the same size pipes and o-rings as previously used by Honda for the original setup. But now I'm getting ahead of myself and even forgetting where I'm at in writing this. In fact - many times as I looked over the oil line layout I was scheming I would get a bit confused. I felt like this bloke who had just turned up at this new city for a job interview and discovered his phone was dead, his map was 40 years out of date and he didn't speak the local language... So where was I?... Machining things and making a mess of the floor, trailing alloy swarf everywhere inc into the housetruck. Not making friends with Hannah or the cat. Anyway. That oil filter pedestal/mount? needed a flat pocket to mount to. I machined away the casing so creating such an area... On the other side of that I machined out a matching pocket. It began sort of like this... ..and continued like ... Because it was so fun I took away more alloy... Now I had a nice location for the mount. This would be pulled into the outside pocket with a custom gasket sealing it, via bolts from the inside going through another bit of alloy that would be machined to help locate the pipes in and out. From the outside it would sit like this... I drilled the mount and then set about to tap the M18 thread. But I didn't have a M18 tap. Its lockdown so borrowing one from someone was out of the question. But I did have a few spare old Mazda V6 oil filter mounts so I nicked the threaded pipe from one of them and made a tap... It worked fine (phew! ) .... I then turned out the oil groove to suit the Honda filter. I didn't take a photo of this but you'll see it here as I was drilling the oil ways through... Drilled and tapped some mounting holes... Now I had a lovely oil filter mount... Annoyingly I didn't take any pics of the oil pump mount but I can describe it. The oil pump bolt via three bolts to a alloy plate. This plate is bolted to the inside of the casing via bolts that come from outside through spot faced locations... The oil pump shaft runs backwards towards what will be the flywheel area where it will be driven by a series of two chains off the crank adaptor - sort of like the original. But backwards and on the other side. That you will see soon along with a network of machined pipes and fittings that almost need a subway map to follow. More soon....

Oh yeah that car- it pisses over everything at the start grid. Such good acceleration! Dude looks to be a good driver too. It used to have a Datsun A12 in it before he fitted the boxer. Must be a thing....

Its just the irony of a big staunch 4wd being called a cutesy name. Like fluffy.

How about the.... 'Poppit 2000'

Just found this thread after the guy had offered advice on my thread. Holy shit. Ive yet to look all the way through it but he seems a bloody talented fella whos bean mucking about with DIY EFI for a long time on top of building some cool cars... https://www.rodsnsods.co.uk/forum/garage/medusa-206057

Oh Yep they've been suggested by others. But too big in bore size and too tall. Edit- the 675 ones.. Not the above e throttle. Caught out posting as ben was. The gw heads have puny 26mm inlet tracts. The k75 are 32mm. Those speed triple items are something like 41mm and oval. I don't have the room to make a suitable adaptor to go down from that to 26mm.

Sweet. Will do. Im hoping I can do a simple enough flange that i can just mill my own. Although our little drill mill can only take so much side load so cuts are shallow and slow making for a dull day indeed when attempting something grand...

No injectors on this puppy. Its got crabs. So my plan was to make some flanges to suit the carbs, with injector added seats to suit. Might even ask of a friend who has one of those high tech workshop tools that cuts things out of solid stock by magic. Complete numpty control?

Yeah I was thinking I could get them sent to my brother and see if he can do the old wink and nudge with karen down at the postshop and get a much cheaper postage rate than the ebay sellers seem to offer.

Hey Hogan- cheers. Yeah I have seen a few snippets of his channel and I must watch more but I always end up drifting off to watch old episodes of the peep show or 8 out of ten cats etc etc. I really must sort my shit out and learn stuff from channels like his on the internets. Funny enough was that over on the uk retrorides forum someone suggested I check out Allans channel too. Whilst I'm here- you're into bikes along with half of the chch crew. Its been suggested on retrorides that the itbs from a BMW k75 would be a really good match for my heads. If anyone knows where in NZ I can try to locate such things that would be sweet. They are available bloody cheap on Ebay uk but postage is a killer. Unless again someone has a good idea on cheaper ways to ship from the UK. https://www.ebay.co.uk/itm/1986-BMW-K75-Throttle-Body-Bodies-13541461113-FREE-UK-SHIPPING-131/264476173551

YES! Yes you should

OK so I had the engine sitting there in pretty much the spot I wanted it. I had taken loads of measurements and pondered many aspects in an attempt to really look into the future and pick up on any potential problems that could arise. It was pretty obvious that the bodyshell was going to need a fair bit of chopping about in the tunnel region (ooooooohhhhh I can see the originality preachers trembling already..) and that the engine was too low in its nether regions. You can see it here. Its not stupidly low and I have seen worse but for a car that has to navigate our driveway with its rocky surface it needed to be better... It had a nice burly bottom but my intentions were to raise that and make a removable sump plate. Still with fins though to help keep the oil cool. Here's what the underside currently looks like... I pulled the engine out and sat it on the bench. The Imp then got its little Datsun heart bolted back in place and reassembled to working order (yay for no more leaks I thought..but it still leaks because British) I poured myself a whiskey. It might have been a few. I studied the crankcase and sump carefully... I then went over my plan of attack. My main issue was the oil pump. It was going to have to move further up in the block so I had to find a suitable place to mount it. I also had to work out how I would drive it. Originally it there was a larger spur gear running off the crank, driving another spur gear. Off the centre of the spur gear was a sprocket which ran a chain down to a sprocket on the oil pump shaft. The oil pump shaft ran not one but two oil pumps. The main pump in the sump area and a smaller scavenging pump in the clutch housing area which squirted oil up over all the gears. The shaft also ran through the main pump to the front of the engine (what is now going to be the back) and powered a water pump. A bit tricky to picture? Well here is a stunning bit of pencil art I did just now ... Plus a photo of the all those gubbins on view at the back. The driven spur gear is missing in this pic but you can see the splined hub it slides onto with the driver sprocket on inner end... Honda had made it all very neat but also all very complicated for what I required. I just need one main oil pump to feed the bearings. So I move the oil pump up. Fine. I'll mill a flat area and make new mounting blocks to suit. But because I have removed the spur gear arrangement (no room for that lot with a custom flywheel planned for the crank) I'll have to chain drive the pump with sprockets (at the correct speed too). OK. That should be easy enough. But no spur gear means the pump will be running backwards. Oh bother. So how about I mount the pump on the opposite side of the sump casing and so turn it around. The shaft is long enough because it goes right through the pump each way. I took the pump apart and checked if this was feasible. It was. Yes! Now why not just run an external oil pump and dry sump it etc ? Well mainly because I am not Mr Money and hence prefer (have) to do it as cheaply as I can with what's at hand (more of a challenge this way and more satisfying too) Also- if I use the Honda pump and keep the required oil routing sensible then it sort of remains factory. I am also going to do my very best at keeping the external look of the engine as clean as possible with a nice uncluttered engine bay. That's just the style I like. Plus we were only just into lockdown here and I wanted to crack on, get as much fabrication as I could done while on my ' holiday in the shed '... So now I had a plan to follow and could start chopping things up. I chopped it just below the engine mounts I intend to use. There is a myriad of long bolts running through the cases clamping them together. The main larger ones are all up around the crank area. Then another two lines of smaller ones below (which hold the cases together under the against the loading of the transmission shafts- now gone) Plenty enough bolts so the lowest are now gone. This lot will be stronger when I have finished with my idea. I kept chopping it up. Took a bit more off because it was fun. Lovely alloy too I might add. Very clean castings. Ended up with an engine a fair bit shorter in height... I got the cuts pretty square and straight. Made easy by the fact that Honda had nicely added reference lines for the purpose- just like on a pack of butter... Now I had to mill it flat. It would take decent sized knee mill to clean up something this size and awkward. Or how about a little drill mill, a steel bench and a big plate of steel I had rescued from a Japanese dentist chair I stripped for bits... I had to position it just right and use the swing on the radial drill mill to run over the cut edges. It looked a bit suspect but it worked fine with light cuts. After the bottom of the sump case was flat and square I then milled a flat area on the face below the crank flange. This would leave a good flat surface, perpendicular to the crank centre line, to mount a plate with an idler sprocket on it for the oil pump drive I had sort of nutted out in my head (but really had not gone any further then just that and it could well have been just nutty) That area ended up like this... The pump would fit somewhere in here like this... Then I threw the lot on the fire... and swept up all the alloy chips that seem to have gone everywhere! When it was nice and warm I welded some new flanges on. Very carefully and slowly I tacked them, taking my time to make sure they stayed true and square and keeping it warm in between tacks. They did. Yay I welded as much as I could reach with my torch along the tricky edge leaving just a few spots that I'll seal at build time with JB weld. It turned out so good that I barely needed to give it a tickle with a larger file, more just a clean up and sits square on my bench. Straight edge reveals my bench is indeed flat too- I had to check! I was so happy at this point because it was one bit of the conversion I feared could go wrong - however I think the warming up and that fact the block is a complex very rigid shape helped keep it all straight. I sat back with a cup of tea and admired my nice burly flanges that I will bolt a plate to...

It would be 22 hours of sleep, an hour of eating etc , half hour of cleaning and half hour of general 'fuck you' cat stuff...

Plus I'm a fucking good looking bloke with with a full head of dashing (greyish) hair and a chiselled manly jawline. I'm also incredibly modest. But I've no time for doing youtube stuff. I entertained the idea and then looked into how much time might have to go into making something decent enough. I feel awkward in front of a camera and don't know that I have that sparkle. But mainly its a time thing.

All in good time.. I have nice bit of 'project thread update buffering' built up. I going to eek the updates out so I don't use up my buffer much. This way I can fool everyone into thinking I'm out there working super hard on the project in the cold shed - when instead I'm actually cosied up inside next to the fireplace, with a fluffy cat, a cup of tea and reading other peoples build threads.

Where did you score the steering wheel from? Looks sweet.

Nice funny write up. Made me giggle. When the panel beater returned the car did he appear to have more grey hair than when he had when he took it away? He's done a neat job. You should be proud (in selecting him)

A nice satin finish is what I am after. I'll come visit soon for a cup of tea and a chinwag.

Cheers fellas. Hey @avengertiger Dave! Are you still doing blasting with walnut shells? I was thinking that might be a good way to clean up the outside of the block/heads. Its a sort of silver paint finish that has corroded away.

Cheers KK. I do actually have a little folder on my laptop dedicated to just pics of sexy looking 911 engines and I think I would probably be banished from Oldschool if I fit anything other than itbs. I'm definitely going to use efi though so sadly, some might say, it wont have the full on classic look of webers lined up. But I plan to try my best to have the engine 'classic' looking, in a 60's race car inspired sort of style . I won't have brightly coloured AN fittings and braided lines etc that for me often ruin a classic engine bay. Here's a neat vid of a cafe racer styled Goldwing, stripped down with 6 webers. Its pretty neat.... https://youtu.be/iuuiHgzlgp8

Sweet! Go hard and get it legal! @Slacker_Sam. This was a conversion you were thinking of doing on janes car at one point?

Gearbox time. As mentioned in the last post I was pretty set on using a Subaru Transaxle. I could also have entertained an Audi unit or perhaps a Renault 21 item but they are harder to find and more expensive. Subarus are everywhere! So way before I had found a engine to buy I started looking. Now initially it was a Legacy front wheel drive trans that I was looking for but when I realised that early Leones also came out as front wheel drive with a smaller lighter 5 speed Transaxle they got added to the list. Not as easy to find though! Then one day a leone boot lid popped up local to me on my Trade me favourite search. I contacted the seller on the off chance that he might have a box. He did. In fact he had two. A early 1600 item and a later 1600/1800 unit. So we went for a drive and paid him a visit and what a thoroughly top fella he turned out to be. A mechanic by trade, ran a local garage before retiring and now works from home on locals cars. However its what he does in his past time that was really interesting. He has been building small hover craft for years and became well known for building one with wings that could fly.... https://www.youtube.com/watch?v=xhGN4gFYPLk But I digress. He had some boxes because he had been using subaru engines for his hovercraft. So I bought a couple of boxes (one which came with a 1600cc subaru engine attached) , two starter motors, an 1800 ring gear. All for bugger all because I think he just liked the nuttiness of my plans for the Imp. So here is a box. The earlier 1600 in the small casing. about 4 kgs lighter with a smaller diff and takes a smaller flywheel.. This next one is the one I'll use... Its a later Leone 1600 T71G which shares the same slightly bigger stronger casing as the 1800cc. Ratios are 1st 3.636 2nd 2.157 3rd 1.266 4th .885 5th .725, Rev 3.583 - these coupled with a 3.9 final drive ratio should suit the Imp pretty well on its 13" 175/60 wheels. Here it is again next to the stock Imp box. Its not too far off but the gear selector is higher and points up at an angle. The box is also taller at the rear so the tunnel will need to be raised and the removable cross member chopped about. At 35kg its about 9kg heavier than the Imp box. I can take that. An interesting and very handy fact is that the box selector rod works in exactly the same way as the imp item, even the movements in are pretty much the same in travel both in rotation and back and forth ! So that is nice. Now as discussed previously there is the fact that the Honda will be rotating this boxes input shaft in a direction opposite to the norm. It has been done successfully with Audo boxes and I know of a fella who has run a box backwards behind a 440ci engine with no dramas. I'd also had the discussion about the new thrust loadings with a fella in the UK who's into Goldwings. Came to the conclusion that being a Japanese box from a much heavier car, optionally with a Turbo. So its not been to much of a worry however more people have questioned it and now I was really curious. I decided to strip the spare 1600 box down (same internal structure but a smaller diff and different casing) I got as far has the last bearing and syncro hub to remove and my puller broke. I'll use friends press but even so I am now happy that it will be fine. 5th gear is the one with the least thrust area when run opposite direction but that wont be so loaded up. Here's some pics I took... A beautifully done bit of technical description in this one showing original (green) and new rotation thrust bearing positions. (My Samsung note phone needs a new stylus!) On a side note- it has to be the easiest gearbox I have ever taken apart (ignoring the fact I need a press to remove some bits from the shaft) so I will take the box I'll be using apart and rejoin the casings for mocking up purposes later on. Much easier on my back. So lets put the box away in the corner and get back to the fun bit. The flat six. I was really looking forward to seeing how much lighter it was gonna get as I removed all the un-needed bits from inside. With the alternator, starter, inlet manifold and coolant pipes removed I weighed the engine. It came up at 105kg. Diet time! I removed the rear clutch cover that has the slave cylinder built in. Removed the clutch unit. Took off the drive gear housing. Ohhhhhh. Clean and shiny. Neato. I was told that this engine was possibly a low mileage unit but I was not to know until I began to strip it. I was fearing sludge or bad staining inside the castings but its super clean. Here's a shot with a few of the spur gears missing and showing the various bits... Clutch unit added back but without the main rear casing on so you can see what it looks like.. This was fun. I like learning new engine layouts. Here's the front of the engine which will now be facing backwards. Cambelt covers removed and you can spot not one but two VR sensors for the Honda CGI ignition setup. It has a 12 tooth trigger wheel which with a tooth removed could be used as a crank angle sensor for the EFI I have planned. More likely I'll make a 36-1 wheel the same size for better resolution. There is also plenty of room for a cam angle sensor to be fitted- Ideally I would rather run this engine on full sequential injection if ("if !?.... hahahaha" they laugh..." he said if " ) I use ITBS. Cam covers off. One of them had some welding. I suspect that the reason is that the bike was crashed and one cover got hit. Fella who originally had this engine for his project had bought a complete bike. You can see the nifty hydraulic valve lash adjusters.. I removed the cams then the heads. Carefully stashed all the bits in order on a shelf I had cleared. All the bolts and bits were being placed in organiser trays I had bought for the project. I knew full well that this project could well drag on for a long time given life etc. With the help of Hannah we split the crank case and revealed all the gubbins inside... Lots of heavy stuff in there to weigh in! Yay. All this stuff I didn't need went in this box... and that box went on the scales... 35kg Sweeeeeeeeet! That's more like it. A little bit more to lose when I start hacking the crankcase apart. Now I'm aware that I'll be adding some weight back with a flywheel and clutch but hey- this is a good place to start. Its now a 70 kg flat six. Next thing to do was sit it next to the box and line some things up... You can see where I'll have to fabricate a bellhousing to fill that 40mm gap. The Imp was at this point in time 'up on blocks' as I had the Datsun engine out to replace the rear main seal and ring gear. How handy then because I wanted to see how the engine sat in place! I bolted the heads back on loosely and slung the lot up under the imp. I lined the transaxles outputs with the driveshafts so positioning the engine front to back. I took a few photos, took some measurements and noted some stuff. I then removed the transaxle from the equation so I could lower the car down so the engine would sit roughy where it will end up. I stood back and admired it. Wow! It just looked so bloody spot on in there! Man - if my juices weren't fizzing with excitement previously as I stripped the engine down they certainly were now. I'll let these last photos I snapped end this update
