Ash's 89 AYDUB11

Recommended Posts

So motor wise there's a fair bit happening on the rebuild.

Bens old 7AGTE

Bottom end is getting 8.9:1 +0.5mm

The rods are mint, huge pauter bastards as thick as my wrist, quite heavy hey I'm not gonna go spending 700 or more so save a little weight

Crank seemed in good nick and bearing wear was good as far as I could tell.

The most part that bothered me was the use of the 7A stuff so a 4AG oil pump and pick up will be used as they pump a bit more.

The other is the timing belt set up. The belt was lose between ex cam and crank gear.

I'm unsure of this arrangement but I read it requires adjustable cam gears witch is awesome cause now I have some cam gear to play with :D

So the MRP timing kit will be bought to solve this and give me reassurance.

Now after crunching some numbers it turns out the 8.9:1 Pistons actually gives you near 10:1

Wanting to use a TRD 0.8mm HG (OEM are 1.2) to reduce my squish gap this would put my 8.9:1 Pistons and 36ml head chambers to 10.3:1

Now that's to high and after talking to some guys they all said to drop it into the 9's.

Barry saying 9.2 is ideal.

Sooo

i needed to lower my comp. the factory 4a head has some pretty ridiculous casting marks in the ports and cylander so I desided that taking casting and machine edges out of the head chambers was the option, aiding in cylander operation, lowering chances of det, and at the same time dropping the compression to where I would like.

After crunching some number I came to taking the chambers out from 36ml to 42ml

At the same time I'm sorting out the ports.

Now the ex ports are pretty small on the 16v heads being a little less then 30mm maybe 28mm.

The ex port on a blacktop head are 32mm and some people take those out for racing

The formula Atlantic heads are a whopping 38mm

So I took the ex ports port out to 32mm witch should help the flow once the turbos spooled.

The bowls taken out as well, and all of the guide support material removed. Then taken to a mirror finish with A polishing compound

The intake ports are quite big, even on the small port heads I've got so those have been left pretty un molestered, the wall was thinned between the valve ports, all casting marks removed, and as much of the guide support as I could.

The cams are pretty cool, their an old cam you can't get anymore. They were a joint venture between wade and Toyota Australia as an upgrade for the 4agze aw11 :D

They measure 267 and 220 at .50 with I think 9mm lift from what I can remember??

Valves and springs we'll haft to wait and see but I've got some HKS and tomei springs sitting here with OE valves and retainers

Head still got more work to be done, I've spent maybe 30hrs on it and probably have more then that to go still.

I'll post some photos when I've got some spare time :D

Braided brake lines in after a bit of pissing around

Started playing around with the BC's, might look into shorter springs as I'm a bit worried about the having to add to much pre-load to get the ride hight I want. Will haft to crunch some numbers on spring rates and preload and see what's up.

Form&function ;)

I've just ordered some rear camber plates so wait till those turn up then drop it and start sorting hight and then sort spring lengths and rates to get it handling nice at the track.

Here's some more photos of the head, cutting out mostly done, about ready to take it through the grades and start on compound.

There's some annoying grooves around the guides I can't get out as I don't want to take it out to far, Orwell...

Oh and that ports not on the piss, photos taken on an angle, your'd be amazed how hard it is to get photos of shiny ports

OEM 4agze throttles pretty small. NA's not much bigger.

On the left is a 7MGTE throttle. Good as it has the same style cold start mech and TPS' are interchangeable. 7MGTE take 2.75 silicone.

Good little upgrade to this bottle neck in the system :)

Will take the NA intake manifold opening out and get a mounting plate welded on to put the bigger throttle

Progressive plenum would probably be better but I'll invest on one later down the track.

Sorting out a decent intake in these things is a pain in the ass. Air flow and heat soak being the biggest dramas. Have played around with a filter in the boot.

maybe adding a vent on passenger side same as drivers and build an air box onto that, il do this at a later stage before cert.

Fibre glass flanges and intake piping aren't hard to make, a lot lighter then alloy. Allthough I'm not sure about heat and pressure resistance. I've got to get some carbon mat so I'll have a play around

Picked up some fish nets :D (yes anouther Toyota with fishnets)

Finley seems to like them too

Drivers sides woren as per usual how ever I'm gonna pull it apart and add more support in the sides.

Kinda need bucket seats but I think new style buckets are out of place and finding a same pair of retro buckets at a reasonable price is un realistic. Plus I like putting stuff behind my seat so reclinable is nice :)

How I'll add more support I have no idea! haha maybe some alloy sides and glue foam either side??

Sand or bread knife the form to shape??

Oh and I have no idea for rails. Any one got ideas? Could buy some form NZKW or someone??

Working threw little gremlins atm while I wait on some suspension and hub parts to roll in

Swopping booster and hilux cylinder over too.

Old one had leaked, pealing the paint underneath it. Seems to be a common thing in these

Sanded it back and painted it, it's a couple shades off so hopefully no WOF guys get funny about it

Long ass acsel cable

Hanging on by a thread

Finley found it fun too

Started on the drivers chair too, will make sure to do a good write up on that

Got started on the seat this evening while watching TV

Kinda nice, flat mates and miss' tend to kick up a storm when I bring stuff inside.

Bits of wire from a wire wheel in a drill stuck through all the carpet was a good one :D

Probably the easiest seat I've ever pulled apart.

Centres take 5mins to take out. Possably change centres between different recaro's if the frame the same

There's some factory side enforcement already so I'll weld some 12mm tube the same to build out the sides more.

No idea for foam. Maybe two part stuff to build off the original foam inner then cut it to shape??

Luckily my mums pretty handy with a sowing machine so I've conned her into sorting a pattern and fabric

FYI I don't normally have this much free time, I've been off work for two weeks so making up for lost time

Welded some tube onto the sides.

Bends look rough as I dont have a tube bender so just cut notches then ran over them with the welder once bent to place

Picked up foam from para rubber. Went through the cut offs and go the lot for $12.

Picked up some ados f2 contact adhesive to glue All the foam together.

Dunno how I'll cut it, couldn't find a cheap enough elec bread knife (all +$60) so I'll try the angle grinder with a thin cutting disk.

Woohoo! Recaro reclinable buckets on their way :D

So I've got no idea where my camber plates are, cars still on stands :(

Reckon they will turn up this week they said

Did a bit of sorting on the rear while its up.

Full rust removal.

Cut the back out under the bumper too, want to make a rear defuser kind of like this red one.

Possably out of alloy the same as my front and side lips.

I've now got some more free time and extra dosh so might get the hubs sorted within the next couple weeks too all going to plan :D

P.S Simon I'm no longer with that crowd so flick me a PM

Visor extent io and front splitter.

Got so slower epoxi thinking it would give me more time to play around, unfortunately it's so slow even with a heater and dehumidifier it's taking a couple days to get it rock solid

UV resistant self levelling epoxi sea to take a lot longer the the west system stuff I've been using

Did a rough measure with the spacers on and dam there's a lot of poke. About an inch maybe.

Soooo

Whole front guards will get pulled to suit, no biggie here

Rears will get cut right back and welded so there will be no arch what so ever

After much debate about rear guards and looking into e30 m3 replica rear box guards I decided something a bit more Subtle would net a better out come, so I've made some mold of the rear quarters out of glass, witch will have a bit of a pull and bigger arch to allow for the wider wheels

AW's don't seem to have much allowance for 8.5-9" wide wheels, especially with some track rubber with a bit of wall

Gotta find something to remove the realise wax off the positive, tried PPG's wax and grease remover and it did sweet FA. It had been sitting for years however, think it's from when denim painted that red crown wagon black.

Using meguiars mirror glaze so will see what the bloke at nz fibre glass says

Moulds taking shape. Had quite a bit of interest of fibreglass p-type copy's to.

Got a couple air bubbles between the glass and gel coat so I'll haft to sort that out before I add chop.

This is because it I don't get a good bond Bowen the gel coat and glass what I pull the negative off the gel coal might stick to the guard and not the glass causing holes in the mold.

Bit of a hold up as I was hoping to get it all done this weekend but will make sure I get it good so I can pull loads of copy's :D
