I need a turbocharger that'll yield me about 400-450RWHP on my S4 13BT. I wanted to know if this was a good choice:

I have no porting done, complete stock block. Will it work? If not, what's a good turbocharger for my goals?

 

You'll need to get a turbo with a turbine a/r suited to the rotary. Those are all too small. Look into some rx7 specific sites, like gotham racing, a spec, rx7store etc.

 

If your in need of a setup for that car I have a nice setup. It would provide the power your looking for. The kit itself is our GT3574, it will provide those power levels. If your interested shoot me a PM.

Would the .82 A/R for that turbo be fine. then?

 

I checked Gotham Racing, they don't have any turbos for the FC.

 

Okay, out of these 4, which one would be best for my needs:

like zero R said man give him a pm. He is with Aspec and they do all sorts of differant single turbo upgrades.

 

Out of the links you posted above i would go with the TO4R for the HP levels your going for. But I would talk with Sean and see if he cant suit your needs.
