Nice! Info on the IC?

Are you doing anything to get air to the turbos or do they just suck from the engine bay?

That's pretty cool, I make a similar setup. Those turbos are huge, how is this car used and what is the output?

Very nice work and very extreme!

May I ask, what is the strategy with two 35's?

Basically that is like one GT-35 on a 1.7 liter motor. Can that drive a GT-35? Where should boost come in?

The best.

Looks good!

How does it run?

How do you equalize the two banks boost?

What about some numbers...?

Thanks!

Brian, Yes I am in Taiwan, Yes I am from GSF. The reason I move to Taiwan my wife is a TV entertainer/ actress in TV series and movie....

I have 2x Tial GT35 R turbocharger ( it is for single 930 turbo spec) with me, I was making 6 ITB with twin turbo setup. The machine shop and I didn't agree with linkage setup, we stop the 6 ITB twinturbo setup..........

I already took all the intake and exhaust parts out of engine and I have all the parts in the shop so I put them together....

One nice thing about Tial GT-35 turbine housing they share same flange with GT-28R and GT-30R.
I can switch to smaller turbocharger within 2 hours...

The aluminum fuel tank cap isn't back from machine shop, for now I can only move the car around not test drive the car......

At idle I can heard the turbocharger spinning....Thanks to Tial turbine housing, It makes turbocharger spinning earlier...

The Aeromotive fuel pump, AN-10 fuel hose, turbochargers, 83 lbs fuel injectors are good for 1000 HP, 6 ITB, GT-2 cam, 41 mm intake port equal length turbo header, water injection. in a 3.4 - 3.8 L motor red line at 8000 RPM....... 800 HP would be a good number.
