I just pulled my head to find something got sucked into a cylinder. So its time to rebuild, right now i have 81.5 je 9:1, crower rods, GE sleeved. I will probably go to the 82mm bore, my question is what do you suggest as far clutch, and intake manifold for 450 whp+. I would like to have a clutch that can handle more but still not over kill 450 whp. Also do you have any suggestions on stuff i should with the motor out other than the obvious bearings, pistons, rings, head rebuild...etc.

 

I have run several 450-500whp integras with competition stage 4's but for anything over that I would recommend a twin disk

As for the intake manifold a Victor X is the way to go.

Wiseco pistons and eagle rods make a good combo for that power level.

 

have a machine shop check the rods for straightness and if they are good, use them again.

my old crower billets are on their 4th engine. still holding.

i agree with the clutch and the vic x.
