i had a 95 hatch running a boosted b20v and i got 20+psi dd with stock internals, head bolts, and tune. now i have a 00 civic that has a b20 that i am planning on boosting without vtec. the thing that kills a b20 is high revs, anything past 7800 and you run the risk of cylinder wall failure, so a good tune and no high revs is key. i like the b20 for boost cause the comp ratio is almost perfect, and the torque makes it a monster imo...
