hey guys i just had new twins put in they are new from the 2001 rz rx-7 what kind of power am i looking at with stock set up or with mods! current set up hks 3 in down pipe, deleted cats to apexi n1 exhaust ,hks twin intake system ,act hd clutch ,walbro 255 fuel pump, new injectors, fluidyne radiator and larger smic ,greddy boost controller setup but not tuned .

 

Without an ecu or prevention of boost creep? About 300 rwhp. Once. Before you blow the motor.

 

The 280hp rating on the late model FD's include the Efini y-pipe kit (not turbo's alone).

 

the 280ps rating includes... turbos, y-pipe, revise intake, hollowed out cat, better muffler, revised map and... more boost.

the upgraded turbos aren't going to make an amazing difference - but a good alternative if you are replacing a set of blown originals.

 

Heh, that's if it doesn't blow the motor before it even gets to redline.

dont they basicly have the same potential as the 93-95 turbos? they just spoll alittle faster i believe.

 

In answer to your PM, you need to put the stock cat (or a hi-flow) back in to replace the midpipe. Once you've done that, set the boost controller for 10 psi.

The other solution is to install a restrictor plate at the midpipe in order to increase exhaust backpressure. Try a search on restrictor plates, there have been a few good threads about them in the last 6 months.
