Borg Warner EFR series? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I've been doing a little research on a turbo upgrade for the near future. I've decided to stay bottom mount as my end state for power is anything less than, but relatively close to, 400hp.

I've seen some interesting builds done with a GT2871 .64 a/r that have reached and surpassed that mark. But, the more I read about the BW EFR series, the more I'm interested. Specifically the 6258 model.

I've heard (but I can't find details) that the 6258 will fit the stock SR20DET manifold with "very, very slight modifications." So I'm wondering what that means exactly.

Has anyone tried this yet? If so, what other considerations for fabrications are there? i.e. oil/water lines etc.
