J Spec 280 Hp
The motors in the latest J spec Rx-7's put out 280 Hp. So, exactly what is it that produces the higher power? I know they have better turbos. Is it that these turbos put out higher boost or what???

The engine is the same....but I think it was the combination of the intake and turbos...

OK, I read the link and it says the turbos are more efficient because they generate more air flow. That suggests to me that the 280 Hp engine runs at higher boost then does our US spec version. Anyone know how high the boost level is??

the rx7 in japan dosent have a cat in the downpipe. there's most of the power right there.
the newer rx7s have a slightly different intake.
the turbos have a smaller impellar for it to spool faster and a bigger compressor to push a little more air.

OK, so with what amounts to a downpipe and more efficient turbos the max boost on the J spec jumps to 0.74 bar (10.7 psi) from 0.62 bar (US spec?) (9.0 psi).
