compression isnt an issue. there is little power to be had by just increasing the compression.

realisticly, your going to spend about 1k to rebuild the bottom end if you re-use everything. If you change out your pistons while your in there and go to ARP rod bolts, you'd be ok to run nitrous, say a 200 shot if you wanted to. 2k just isnt going to do too much for you. i would say the Lloyd Elliot package would be right up your alley for 400whp n/a but it'd put you way out of your price range when its all said and done.
