you could easilly hit 250 on 8psi and an exhaust.

 

250WHP without boosting?

 

oh without boosting. that'll be harder. what engine are you working with?

 

STOCK '06 Si

 

wait a couple of months for an aftermarket. i know Japan aftermarket companies are all over the new SI

 

I figured so...I hate waiting!

 

Toda has some great kits out for the K20 in the RSXs, and im sure it will fit the si, you might look into that and a set of individual throttle bodies. with Todas head package and the ITBs, 250 wouldnt surprise me at all. those motors spit out power like mad.

Toda is the king of NA honda stuff. You should take a ride in a 99/00 ITR with a set of VTEC KILLERS in it and a good tune. Totally different beast.

 

prolly a less.



Full exhaust, intake, header, hi-flow cat..........cams, valvesprings and retainers......new intake manifold or maybe a set of individual throttle bodies........................etc
