i'm not sure what your whp would be, all cars are different. but with I/H/E, chipped ecu and a vafc i made 176 whp.

heres the dyno plot if your interested.

why don't you call around your area to find a shop w/ dyno to check it for you. the shop i went to wanted 30 for hp check (one run)

 

i got 189.4 whp out of an h23 with stick ecu and bottom end
