I picked up a b18b1 with 136k miles, was planning on doing a high compression N/A build,
was thinking about dropping some crower stage 2 cams in there as well as 81mm Nippon racing 11.57:1 pistons, and apr rod bolts,

from there i'm not sure what else i should do to get some extra power out of the block or head? any suggestions?

 

porting the head will obviously help. maybe a thinner HG or milling the head to up your compression a little. the hytech rep also seems to be a popular for all motor builds along with a TB and decent flowing Intake manifold

 

got some stage 3 crower cams and cam gears for sale for cheap. Gave it a good bit of power, just went boost. I would suggest them over stage 2's if your wanting to make power with an ls

 

What are your goals with this build

 

i'm trying to make 180+ whp , was thinking about going with 84mm bore, and ycp pistons with npr rings,, and how much for the stage 3?

 

with skunk2 adj. cam gears 350 shipped as long as your in the states

 

I built an all motor B18B before and I only got up to 165WHP. I had pretty much everything done to it as far as motor build (even blueprinted build) but again, this was over 4 years ago so I'm sure they have better parts to make better HP now.

I had high compression CP pistons (11.5:1), H-beam rods, knife edged crank, ported/polished head, crower valve/springs, crower stage 3 cams, adjustable cam gears, intake manifold, throttle body, etc..... I had an Apexi SAFC and got it professionally tuned..... results were little disappointing considering how much I spent.

I later went with an B18C VTEC head for LSVTEC setup and made 189.2WHP with port/polished head and ITR cams, crower valvetrains, Edelbrock manifold.

It depends on how much budget you have to spend on your engine build. I love N/A setup better than turbo. it's more fun to drive and less things to worry about. Good luck with your build man.
