  1. So 2 weeks before moving to the US this happens! Guy in OZ is rebuilding a T57 and needed a new block. So got to and cast one up! Didnt go 100% but still really well. On a plane to LA in 3days!

  2. Got the fwd alternator bracket to work with the rwd water pump. this lifts the alternator up out of the way of top suspension link. and bit further away from mud and crap. just had to modify the top mount to bolt to top water outlet and waterpump. also make a new inlet for water pump fwd bracket already had some racing holes in it from when it was on the starlet? Started making some towers to go around the towers. getting the sheet to do what i wanted wasn't much fun,, but turned out alright after being thrown on the floor a few times not much clearance to turbo is main issue

  3. Right, to get back to where I was lastnight before I was called away for Pizza and Wine (oh, gosh, what a chore my life is....) Babies. Go have one. Now, honest, totes legit an awesome time :-). There are shit parts, but wow, overall its actually pretty awesome. Work has been really busy, surprise surprise. I did _a lot_ of this: In order to get the car we've just finished building going: And go it does. The new track at work has been sealed, its got an (almost) straight that is about 1k long. Listening to this thing bang gears down there is pretty awesome. We've all been promised a drive, but I'll believe that when it actually happens. Sooo, back to RX7 related things :-). Because I'm an idiot and could just go the easy way, I gave making (instead of buying) a sump brace a go. Lots of tracing and scanning got me a cad model of what I wanted. I used a table cutter to cut out an outline of what I'd cad'd on paper, to see if I was on the right track. It all matched up to the gasket, so I committed and cut the profile out of 1/4" 316 stainless on the waterjet: One of the first jobs I had when I got to work was to get the waterjet cutter sorted. Its a Chinese machine, with some terribly translated NCStudio software on the controller PC. With a bit of finesse though, I can hold a pretty decent tolerance on it, around 5 thou or so if I really try. This job didn't require such accuracy though, so I didn't replace the orifice or nozzle or anything, 0.25mm is close enough! The profile cut out really nicely, and matched the gasket spot on. One thing that bugged me though, and seems to be the same on most of the commercially available sump braces, is that they don't have reliefs cut for the stiffening ridges pressed into the FD sump flange. As you bolt the brace up, it would just squash them flat into the block. With a bit of white paint to outline the ridges, and a few photos, I got the location of the ridges onto my model, and cam'd up some toolpaths for the CNC mill: Yeah, an example of brilliant fixturing once more, but it worked and didn't chatter... much. Was my first time machining stainless, with a 3mm end mill none the less. No breakages and actually a really good surface finish. GWizard is my friend. I grabbed some new fastening hardware, as the bolts originally holding the sump on were a bit of a eclectic collection. A coupe of them were actually too long and weren't clamping the sump flange at all, no doubt contributing to the leaky leaky... A thorough cleaning later, tapping out all the holes to remove old sealant and the sump went back on. There was also a broken 6mm tap incident that put a hold on play for a couple of days till I figured out how to get it out... heh. I used grey 3-bond sealant, as it is 100% the best stuff I've ever dealt with. Its one of those products that has a distinctive smell. You know if you ingest of inhale it, its going to be really bad for you, so that means it must do a fantastic job. Honestly though, if you're sealing a sump on, its the only way to go. So that will be the oil leak from the rear of the sump fixed, woohoo. The engine mounts will now be sitting 1/4" lower then they were (thickness of the sump brace), raising up the motor 1/4"... However, when I took the motor out I wasn't really happy with the condition of the factory mounts. They were 'ok', but could be better. Some googling later, and I discovered that factory replacement mounts are really really bloody expensive! Some more googling of engine mount suppliers, and I found that 1979 - 1997 land rover engine mounts are a similar studded hockey puck design, and almost expactly 6mm shorter than the factory RX7 mounts... Perfect, that'll sit the motor back in its original location :-). I'll post another update later on with some info on where the intake / sensor system is up to, and the turbos. Cool stuff going on there :-). Cheers all.

  5. yep train nerds are the worst, hanging round the gates, perving at the defensless loco's you should see it when the royal scotsman is in, foamers everywhere. only train i like is a dead train... or the 55 class napier deltics that come in, mainly because of the engine, could take or leave the train itself, but it has a cool retro shape, so ill forgive it when it was in

  6. Before I could commit to any further work on the bike, I needed to know if the engine even ran. Before I can even see if the engine runs I need to remove the fuel tank, drain it and see if im getting fuel to the carbs. The tank is pretty easy to remove once the seat is off. You need to remove the little cubby box at the front of the tank Under that, and at the rear of the tank under where the seat would be, are four bolts. Two long at the rear and two shorter at the front (they are removed in the photos already) The guide I was using said to take the handle off the fuel tap. Not sure why, maybe just to reduce the chances of breaking it. The top fuel hose on the fuel pump is the inlet, so off that comes, and then it’s a matter of lifting off the tank. I forgot to take a photo, but under the tank is the air box (big black box in above photo). The filter in it was in good shape, so that’s one less thing to buy. I pulled the air box off, and finally had access to the carbs Before doing anything else with the carbs, I drained the fuel tank. I had issues draining through the fuel tap and filter, there just wasn’t any flow, so I resorted to just tipping it out the filler. This was a bit messy, but quick. The bad news? The tank is rusty. What I thought was half a tank of gas, turned out to be about a litre of petrol and half a tank of rusty water. Guess that explains the flow issue. The inside of the tank is rusty. Not too flaky, but will need to be worked to get rid of the rust. It doesn’t look deep, and there are no signs of it coming through that I have noticed. I can still see patches of clean metal around the place, which is a good sign. There are a few different methods for removing the rust. You can fill the tank with water, nuts, and bolts and shake like mad. The preferred method (because I like to make everything more difficult) is electrolysis, or removing the rust using a sacrificial bit of metal and lots of electricity. I’ll look further into this, but I think the tank can be saved. The other thing I had to do before I could crank the engine, was to drain the oil and fill with fresh oil and a new filter. Remember the old filter? Yeah that’s been replaced And although the oil was thick, black and really bad smelling, it had no chunks or metal flakes in it. I filled up with 2.7L of Penrite MC4ST 10W50 semi-synthetic motorbike oil. Nice golden colour. Now, because I still haven’t purchased a new battery (don’t want to invest $100 into a battery if the engine is poked), I had to use the big 500CCA one I removed from the Rover…… Lets just say I don’t have a photo as it was bit of a dodgy setup using really long home-made jumper leads and clips just hanging on the bikes battery terminals…. but it worked We have power! All the lights work, even the hazards Speaking of dodgy, this was my “fuel tank” to try to supply fuel to the carbs Yeah, that’s probably not that safe. Oh well, fire extinguisher was near by! Anyway, the carbs didn’t take much fuel at all during the testing. Whether that’s because they need to be fed with the fuel pump, or because they just aren’t in good shape, I don’t know, but I ended up feeding fuel straight down the throat of the carb. After much cranking, something amazing happened…. It made vroom vroom noises. First start in at least 2 years (if not 4, depending on when the owner last started it). Engine ran good for the couple of seconds it was running, with no bad noises. Exhaust sounds awesome, even when it’s only hitting 5000rpm or so. Cant wait to hear it at 15,000rpm! So the engine runs. The carbs are in dire need of a rebuild and the tank needs the rust removed, but otherwise its all fairly straight forward now. I don’t know if the gearbox does gearbox stuff, but I’ll deal with that later.

  10. The little Fiat seemed to be running horrendously rich. There was fuel oozing out around the emulsion tube due to a bad seal. Also, it turns out the mixture screw was set 7 full turns out... 6 and a half turns in later and it's much better. I took it for a good fang up the road and the plugs are a much nicer colour. 3 days after this, a carb kit turned up. So easy to get at, I love it. Minutes later... Take one of these and call me in the morning.

  11. Spent some time on the weekend with the help of @kempy with good results. Some of the stuff I remember: Changed one-way valves on injector pump, cleaned points, bled injectors, replaced injector, adjusted fuel regulator to 110psi pressure, cleared return line, adjusted overfuel lever, replaced 6 (yes 6) totally dead spark plugs, re-timed and marked ignition, swapped distributors, lost all the hair on my arms and temporary hearing whilst fireball from backfire on intake gave @Geophy and @Threeonthetree a good laugh (possibly due to me holding a can of engine start that was also on fire) and then started car. Next steps - sounds like slight miss on one cylinder but no cooling system plumbed in, so, reinstall radiator, tweak, and do skids / road test / fix all the other stuff I find broke. Finally making progress = win.

  16. Trimmed each side of frame. Left hand side slightly more than right. screen capturecertificity.com And probably the most important note, make sure the motors drive shaft is aligned with the centere of the swing arm for the chain to clear either side. This pic show the motor 30mm to low. Also make sure the motor is mounted parallel to frame otherwise the output shaft will drive on an angle can cause the seal to leak picture hostingcertificity.com Cut some tabs upload images freecertificity.com temp image uploadcertificity.com Add some kneed-it or LPG mig them in place (Rusty chain is temp to confirm all aligned ok) uploadimagecertificity.com Cross fingers they don't fall off. Looking at pic's probably should have made the tabs have a slightly larger lap onto the frame, feels solid enough for now.

  23. Made some progress getting the rpm signal to the car, brought an LM2917 IC and put it together, the datasheet and maths was a bit much for after work so I messed about with it until I figured out how it worked. I then rigged up the arduino to generate 5 seconds of 1000rpm followed 5 seconds of 6000rpm as a test signal with a multimeter on the output, its now outputting roughly 1V/1000rpm, just in time for the weekend to try it in the car.

I filled out the online form for getting this collected from goat, they called last night saying they would collect it today. its a bit too soon as it still needs to be moved out of the shed and I still haven't paid them to pick it up. The tow truck driver is named barry which I thought was appropiate. I should hopefully get it late next week

  30. The rear callipers are now secured to the diff and were spot on using the brackets I had fabbed up. Old School FXGT callipers (fit under 13” wheels) Series 2 RX7 new discs 4 x 110 I’m replacing the countersunk stainless brake disc screws for more high tensile options and probably moving away from the allen key also. The old hard line is in place however I need to cut and flare/adapt to suit soft lines. These will need to be custom as the FXGT callipers are fine thread and the old Mazda is coarse thread. I might be able to fire the LH soft line directly to the T junction if I play my cards right… Another step closer…..keen as to button up the rear end so I can move onto the fuel system and wiring.

  31. Well sorry guys. I never did update this thread, Needless to say it all went swimmingly And I managed to get it all wired back up. I never got to see it start up, as I had to go on my bike trip, and they had to do a service on the motor, Bike trip was epic, way more epic than fixing a train. But fucked train paid for the trip so yey for fucked trains Apparently it started first try with no wiring faults. So pretty happy about that. Especially since I was a month under best estimate and 4 months ahead of what they expected. It's back in for a service (I got a permanent job out of the cab replacement, and doing a bit of servicing and fault finding to the coaches) So work for them full time now. Any way. Here's some pics Yeah so that's it, It's also taken out some other retard who jumped in front of it, but they went under the murder train so no real damage.

  33. I dont have anything in particular to say right now, except for that I've started working at HP Academy in Queenstown. I have learned a mind blowing amount of stuff from Andre and co already. Motec M150 is just some next level shit. Sheezus. With the M150 you can write your own code for the firmware, today we were trying idea of IMAP / EMAP as a load axis. (intake manifold pressure divided by exhaust manifold pressure pre turbo) Which is a bit of a mind bender to me but apparently this compensates for VE changes etc relating to altitude and turbine efficiency way better than just MAP or MGP. Next step is to take the GT86 for a hoon up a mountain and see how well the AFR stays on target. I'm not sure if it's obvious from this post yet but holy crapping Christ. What a company to work for. The other day Tony Quinn's Pikes peak car was in for a tune before heading off again. It runs a VR38DETT mid mounted, runs two turbos > two intercoolers > two plenums (connected with a balance pipe) Looking at the intercoolers with the thermal camera we found a 20 degree temp difference left to right. Some more poking around from there and we found that one of the intercooler hose clamps was loose, so intercooler on that side had lower mass flow so lower temp. TL;DR: This thing is a fucking weapon, Andre got another 100hp out of it just with tuning. Same boost. ~950kg and now ~605hp atw with plenty of head room. Just stopped there because he wasnt sure if it will still be drivable, going to Highlands for testing on Saturday.

  34. I have been doing a little on this when I can & today since I have finished refitting the rare option (for NZ new) heater I was able to fill the car with coolant & run it until warm I can report no leaks from heater & thurmostat still works. Water stains shown are from driving around with wiper spindles removed many years ago & the new goal is to get this back on the road before I restore interior etc. So while outside I gave it its first car wash in over a decade then drove for a few 100m's round the carparks

  44. Nothing too exciting going on with this. just working my way through all the stuff in the way, to get the extra up travel. Driver side engine mount got chopped off and new one made higher up to clear the top link. Alternator had to go as well. will use a fwd bracket to move it up. a new inlet on the water pump should make it work with the rwd pump. Last thing giving me drama is one of the steering links and the the sump. if can get another 30mm clearance between the 2, this will be max up travel on bumpstops. kinda lost count but got around 3 inch more up travel than the leaves other than that just been welding... bottom chassis link mounts are on for good. i forgot to drill the lightweight hole in this one. Crossmember was way too much to weld with tig, and was to lazy to drive an hour to my old boys to use mig. Arc it was. still got a little work to go on it

  47. Fitted my Nissan S12 Turbo body kit that I had imported ages ago. Looks good having some 80's aero on there now. Was good to take it to the Classic Japan car show here in Melbourne recently but it was running like crap that day especially. I've had a lot of trouble getting the carbs running right since the conversion, they were always running super rich after trying everything. I even took it to someone else who supposedly dyno tuned it but he just pissed me around and gave it back to me running exactly the same...
