Typo in the title: 2971r -> 2871r
Got an amazing deal on a partially complete turbo setup (2871r, Kraken top mount, full 3” exhaust, clutch, injectors, etc) for my extremely-clean 2005 base. My current plans are to run with the stock engine and 5 speed for a little while and save up for forged internals for my VVT and a 6 speed trans. I am worried about the stock rods and 5 speed, so I was thinking of capping the boost and making 200whp for street with a switch to activate ~240whp when I want a little more. My question is this: I am super aware that this turbo is overkill for a 200-250whp setup. Will it be drivable / enjoyable? I simply don’t have the cash to go full send on a built engine + 6 speed and like the idea of 300-350whp in the future, so might as well live with a laggy turbo for a bit. Thoughts?


Car in question on the right. ND is also mine, but it is more track focused.

 

There are a bunch of 2871 variants. The 48trim compressor for example is quite nice at stockish bottom-end-limit power levels. It will come on later than a t25 but should have slightly better top end. The standard 56 trim isn't ideal at that power, but it will still function there without issue.

 

Yeah basically what Ted said, there's a few 2871's.
Regardless, you have it, so use it. It will work, and it will be better than no turbo.
