not that this has everything to do with the inntial topic but since i was mentioned i would like to set the record straight.
i have run a mini-me setup (A6 block-Y8 head 11.0-1compression) with 11psi JRSC boost with 25ish nitrous shot...this dynoed to 189hp and 174trq. this WAS with stock pistons and rods. this configuration was damaged by running an extended high speed, full boost and juice fifth gear run(speedo was WAY buried). stock cast pistons were subjected to severe stress and reponded by cracking at the ring lands. engine was reassembled using forged pistons and rods with slightly lower compression(approximately 10.3-1) and fed a slightly larger dose of nitrous. this configuration has dynoed at 200hp and 165trq. anyone who knows my car will verify the fact that it is no race car being complete interior plus the usual 1/2 ton of misc. junk floating around in the back. also being a sohc means the the best Dseries trans is equal the the worst Bseries trans. as far as being a threat i can hold my own.
<rant mode off> with all that being said can what was intially asked be done...quite possibly. but the most important thing is tuning. don't think that you can just bolt a few pieces on, add the juice and be ready to go. tuning is the key to increasing power by the amount you want and still retaining some sense of drivability and reliability. as other have said start smaller and work up from there. a standalone is most helpful (work great for me) but is worthless if not tuned with the help of someone who knows the path.
