Its been a long time coming, but I'm finally able to get my first FD. I'm looking for a quick street car, not a crazy track car. However, my last project was an Eclipse GSX running a GT30R turbo at 25 psi....probably up around/over the 350 awhp range. Of course you get used to it and always want more. With a street port engine, and all supporting mods, including meth injection, can I get 350-400 rwhp on 99 spec Efini twins? sequential or non-sequential?

350rwhp is pushing it for Efini twins. The Efinis have basically the same compressor performance at the top end as the stock turbos. Running any stock turbos in the 350-400rwhp range will burn them up early. 250-350 is where I'd run stock turbos.

If you want to push the 400 mark with reliability go with single turbos or BNR stage 3s.

I'm not a fan of nonsequential unless you're going to do the full conversion, grinding/porting/welding doors shut and stuff, or unless your sequential simply isn't working and you don't want to fix it.

With my eclipse, to get the low end response I wanted from a small turbo I had to push the limits of efficiency...and pump gas, with 22 psi and was forced to run methanol. I just love the response of the twins since its not the torquiest motor by design.
