Turbo Flanges??

[japmadlad]

What turbo flanges are needed to fit to the SR20DET? I'm not sure because garrett say a GT2871R is a direct replacement for the SR20 but list it with a T25 flange. An american site called www.horsepowerfreaks.com seem to list the same turbo for nissan silvia with T3 flange & all the while I thought it had a T28 flange so I'm anyone shead any light on this please?

OK, ALL turboed S13, S14 and S15s (regardless of engine fitted) have T2 series turbos (T2, T25 and T28 are all in the same 'family' of turbos) and they ALL use the same 'T2' flange from factory.

Understand?

Yeh, both have the same sized flange.
