if you are making anything, its about 170-175 with good TQ, like 125-8 ish. You can make 6-8whp with a good race header and another 6-8 with a decent "stage 1 camshaft." so call it about another 15pwhp with a race header and a cam. untuned, however you might see 182-185ish. tuned, maybe up to 187-192ish whp. its going to be interesting to see if you can get it on stock CR. 10.2-6 (dont rememeber what SiR-G is off hand) might not be enough... but put a point of CR in your motor and a valvejob to match your cams... then I bet you could see 200-210 from there depending on your tuner!!! play it by ear, have fun and do a search. there is someone on this board with BC3+ tuned by C.A.T. making 200whp (188-190whp) (in one day I saw a dynojet read 195, and then a few hours later read 206.5 at C.A.T.'s dyno no tuning) with a head setup by portflow and I believe he has a JDM DC... search! good luck man.
