Heres a youtube page with a few of the cars my mates and i’ve done, we’ll be adding more content as we dig it up, we also have a couple of shitboxes under repair and a build or 2 coming up which we’ll chuck up there as well.
My AWD IS300 ~600awhp
Kierins’s Candy Purple supra. (670rwhp in the vids, had made 850+)
My brothers 600rwhp white RZ supra and the build on his Black SZ coming soon.
Theres also a flood salvage supra we call swampy we’ll be getting stuck into before too long as well.
The link doesnt work so just youtube search pov300 or awd is300.

I have worked out how to use a rwd block in my awd application, the block is machined ready for assembly. I have an event i want to go to so i have to get committed and knock everything out in 4 days. Ive got to assemble and dress the engine, drill and tap my thick wall stainless exh manifold for egt sensors, replace the turbine wheel in my turbo, reinstall the diffs, engine, gearbox and transfer case, axles and driveshafts, convert my fuel system from non return to return system, test everything is safe, give it a light road tune and pack it up onto a trailer and drive 500km on friday.
I havnt got ahold of a 3.73 ratio rear diff to match my new front diff yet so i’ll be sticking with the short 4.3 until after the weekend.
The new setup will be a rwd block,9:1 86.5mm cp pistons with hd pins, pro drag i beam rods, a standard head with my uprated valve springs and 276/276 cams, the rest will be the same as before.

|Awd300||My awd block is scored in the bore and will need 87mm pistons to bring it up to spec so after comparing my awd and rwd blocks i have worked out a way of using a rwd block with a few mods to address the differences and just use the 86.5mm pistons i already have. My turbine wheel also lost some material so i’ll have one of those on the way soon too. My ported head is also in need of some attention so i will put my cams and valvetrain into my spare stock head and use it until i get around to cleaning up the damage to the quench pads on the ported head. I’m still undecided if i’ll spend the money and get billet main caps, my goal of 750awhp should be achievable on stock main caps but its one of those piece of mind items for my power goals.|

|Awd300||Parts have started arriving, i scored some slightly used forged pistons for cheap, main studs, 6x exhaust egt probes, my new 3.73 front diff (old one was 4.3 which is way to short) will be here soon then i’ll source a rear to match and i also got an msd fuel pump booster to use to supply my ignition coils with 14-16v|

Results are in, 2 melted pistons and 1 that pinched the ring, all bearings still look new, hopefully .5mm overbore will be adequate.
The more i liok at it the more it looks like boiled fuel in the rail. I’ll be switching my non return fuel setup to conventional return style system, i also bought some egt probes, i purchased some barely used second hand cp pistons and i also got an msd fuel pump voltage booster for cheap i’m going to power my coils with.

|Mathieu Bernier||Sorry for the engine problems, Pretty sure you'll be back on the road soon. Pretty Crazy built!!!|

|Bempa||Such a beast with those numbers and AWD, it´s a really uniqe car you hav built. I´m sorry to hear about the engine mishaps and I hope you get it sorted out and repaired quickly|

I had some bad luck a couple of weeks ago, i gave it a mild road tune to get it driveable before it went on the dyno, it felt pretty strong, got it on the dyno and it was rich as expected as thats what i set up in my road tune, it went on the dyno and put down 437awkw (590awhp) on gate pressure (18psi). Given its a dyno dynamics (reads about 10-15% lower than a dynojet) and had the drivetrain loss of the awd, th400 and 6000rpm converter.
It developed a slight miss, we changed the plugs, the ones that came out looked fine except the one that had the miss was a touch darker. Put new plugs in and the miss cleared up, unfortunately 3 pulls later it melted cylinder 3, i suspect boiled fuel in the rail, it was ridiculously hot that day, i havnt disassembled it yet as i havnt had time but will be this weekend so i should know more by then. The data logs all look fine and there is nothing to indicate an issue, afr was 11.0, timing only 12-15 deg, boost 18psi, iat 40degC, coolant temp 89degC.
If i had egt probes i would have caught it in time.
I’ll replace pistons and whatever else is damaged, add egt probes to my manifold and im going to do a set of billet main caps while it’s out, it rolled off near 600awhp easily and assuming 150hp drivetrain loss through the awd and th400 thats getting up there by the time i add in another 10-15psi boost.
The awd setup is performing brilliantly, it just comes up onto the converter nearly immediately, pins the tacho at 6200rpm with full boost and holds it until roadspeed catches up, rev’s out to 8000 then pick another gear. Without the stock trac on it will spin the fronts or rears depending on the surface, with the trac on it touches the brakes on the spinning wheel and brings it back under control quickly and smoothly.

|Awd300||Ive put over 1000km on it so far and the awd conversion is working perfectly, on my road tune 18psi its mental, ive never been able to put more than about 10psi of boost down under 100km/h rwd, now it just comes on boost, pins the tach at 6000rpm and gets down the road until road speed catches up to rpm, as rpm approaches 7000 it starts spinning front tyres but the factory trac touched the brakes on the spinning wheel and gets everything under control. Injector flow calcs estimate about 460awhp at 6000rpm, as i rev it closer to 8000 it makes more but i didnt log any inj duty on that pull. On my hoosiers drag radials and 30psi its going to be very quick, my dyno tune is booked for sunday this weekend so providing it doesnt have a failure it should be ready to race. Mt T51r comp cover mod came back and sounds great.|

|Awd300||I had a hard parking event to attend, the comp cover didnt turn up in time so i went NA. 😂|

|Awd300||Wheels are on, offsets, sizes and alignment settings give perfect fitment for my street and drag application. No obvious mexican offsets with stretch tyres or mega camber, just a flat contact patch on the road with tread inside the guard line and a square tyre shoulder to protect the wheels fron stone chips etc.|

I was all set to hit the dyno sunday but unfortunately Australia Post lost my turbo compressor cover that is getting a 51r mod. It turned up after we logged an investigation, its completed and on its way back to me but wont be here until monday, unfortunately my holidays have come to an end and i’ve missed my window to take it 500km to the dyno. My next opportunity wont be for 3 weeks or so. ☹️
Wheels have tyres on them now, just some federals for street duties. 235/40/18 on the 18x8+32 and 265/35/18 on the 18x9+38, the roll out is .39% different which is well within the tolerance for the awd and the abs/vsc.
Wheels are Team Impul Racing NS GTII lightweight Race Wheels. The 18x9 is 8kg (17lbs). They used to be white, i had them soda blasted and sprayed gloss black and stripped the blue paint off the center caps to reveal a spun stainless finish.
