GTM TT build - OCT 15th

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.
