GTM TT build - OCT 15th

350z 6spd

Yes, the exhaust side is a .86 A/R but it's a GT2860RS

Cool, thanks. So this turbo is used on what they're calling a Stage 2? What turbos do the lower stages use?

I used a 48 trim GT2871R with the 0.86 A/R turbine on a Celica build and I didn't think that turbo was very well suited to the application. I felt it was really laggy and then it came on like a hammer at 4200 rpm, which really sucked on a FWD car. That turbo replaced an earlier kit with a smaller IHI turbo (VF23). That setup was never going to impress anyone with numbers, but it spooled right up and gave the car a bunch of midrange power it never had.

It seemed like my old setup was kind of comparable since the Celica engine was basically half the displacement of the VQ37. I'm currently working on a different Celica with the same turbo this kit is using, so I'm curious to see the difference between how the two turbos behave.

The stage 1 kit uses the same GT28RS but with a .64 A/R exhaust housing.

I get full boost on my car around 3800-3900 and I have the stage 2 kit on my 07 HR 350z. That sounds a little late but it still provides plenty of low end torque while cruising if you need to pass someone around 50-60mph or at highway speeds.
