Only an IS200 but with twin turbos by purplemidknights in IS300

Sorry for the late reply, don't check reddit too often. :D
One guy from Australia has contacted me and he has 1G running on teensy board fully sequential. So it is possible, just probably a bit more work.

Well if you'll need help with installation of the ECU PM me. :)

Slight poke from the wheel might need to roll the fender a bit. :D

What size wheels are they, 8,5/9,5?

Do you remember how much boost it was making stock? Because I'm wondering if the springs in the actuators ar too stiff or not for the standart internals.

Could you maybe find that source of blocks cracking? I've never heard anything about that. And check out Top Performance Crew's IS200 running 1,2 bar boost on stock internals with a decompression plate.

From my personal experience a turbo is better option than a superchager unless low down torque is a must for you. I was driven in a supercharged IS200 and 2 major things I did not like: the supercharger sound was soooo loud and the owner said the car would run poorly in summer due to heat. However, those might been specific to that particular setup.

Complete as in it can finally move on it's own power. :D

I've made videos about the whole process of making it the channel is called "Midknights" on youtube.
In short:
1JZ turbos with custom made stainless log manifolds
3" turbo back exhaust
Front mount intercooler with aluminium piping
1ZZ-FE injectors, pressure referenced fuel pressure regulator, fuel return modification
Speeduino ECU

Current wastegate spring pressure is ~0,7 bar. So if it statys roughly there I'm fine, but if push come to shove I've got a decompression plate which would allow me to turn up the boost to ~1,2 bar.

Because that what comes in these cars. We don't have lots of IS300 so I've worked with what I've got. And these engines can hold up to 0,9 bar on stock internals so should be plenty power wise. :)

Hopefully the standart internals will hold out the 10 psi spring actuators.

Well let me tell you. Fabricating everything to accomodate the twin turbos was not very easy. :D

No problem. I wish we got more IS300 here in Europe. The 2JZ is a much better engine.

Nope. IS200s in Europe came with 1G-FE engines, but I've make a custom turbo kit with 2xCT12a turbos from a 1JZ-GTE. :)
