LS (sub<)300HP What is needed?
Motor has been using a bit of oil here lately, so look likes about time for a rebuild. The motor is a B18a w/ about 180k, and i'm running a 14b @ 8 psi. Now I plan on keeping the 14b around so I doubt the fresh motor will see much over 14psi. What should be replaced with better aftermarket counterparts to be able to withstand the massive amount of power i'll be laying down :P. For sure i'll be going with all new bearings/seals/rings, along with ARP head studs & rod bolts, but what else do you guy think i'll need. Thanks

Throw some tuner toys rods and x brand forged piston in if you got the extra coin but if not just do the ARP gear and a rebuild.

I made damn close to 300hp dynojet numbers on my stock b18b small 16g, dsm 450's, walbro pump, logmanifold, srt4 ic, running ectune with a safe tune and the wastegate actuator opening up on top @ 17psi pump. If that gives you any idea. Your gonna be hard pressed to bust 300hp on stock cams I think though. Delta regrinds FTW!
