So I have been working on this for a couple months maybe one day a week when I have time. I have kept a pretty active build thread on the supra forums but I thought I'd share some pictures and info here for fun.
Major parts are
2jz gte vvti motor
Cast manifold
Bullseye 68mm turbo (good for 900+whp on e85 with the current turbine wheel/housing)
1000cc injectors we are going to start on pump gas
6 speed transmission from a 350z
Spec twin disk good for 900ft lbs
Pro efi 128 ecu

Im surprised i have not gotten more negative post cats for this build thread yet.
custom intercooler i had made to a solidworks drawing. Fitting a large core is difficult even more so with a longer motor so this is what we have to work with. It is a bell intercooler core. Everything will be vband and vanjen clamps i hate intercooler couplers.

haha thank you sir
It is on supraforums but i dont want to link it and get in trouble. Anything i work get done moving forward i will be posted on here and there though
.
Yeah i had a GR sti that i attempted to daily drive when ever it was running before pulling apart the miata for the 2jz swap. I ended up selling it and buying a new prius
.
Here is some videos of that dump lol. My goal was the first GR sti in the 10s..but instead if bent a rod bolt or two on a turbo tuff i beam and then i ended up just putting a smaller 58mm turbo in and a lighter built motor until i sold it 400whp was boring

Someone should make a setup to use one on a BP it is cheap and would be a good replacement for the current 6 speed swaps even though they are pnp.

Motor can go back in with the trans once we get the pilot bearing i ordered. I did not like the bushing setup that came with the swap kit. I also got the valve covers cleaned up and some -10an fittings welded on.

Oh damn. Straight six Toyota engines are my jam.
I tried my best to break a 7.5 behind a 350 whp 302 and I just ended up breaking the c4 trans... after 10 years of constant abuse.
Any more pics of the dif mounted to the rear subframe?

lol....
All i did was find out my maximum size i could fit, then draw up a model in solidworks with how i wanted end tanks and the 90 degree vband end for adjustment on it then sent it to a shop called fathouse fabrications and then a couple weeks later my intercooler showed up. I did not choose the core or any details around it, it a quality bell ic core though.
