i have a b18 with all possible bolt ons.. i have a stock bottom end (for now) and just wanna get your opinion on what cams to get the crower 403's or 404's.. i know the 404's need more compression to be very efficient but i've seen people with great power on stock bottom end on the 404's... what would you do? would you get 403's then wish you would of gotten 404's????

 

b18XX ? vtec, nonvtec?

would be useful information.

 

non-vtec sorry

 

I would go with the 403's if you dont want to touch the bottom end.The 404's will work better with a higher comp ratio.

 

even 403's are pretty big for a stock b18a. you're not really going to get the full potential of those cams without bumping that compression up a good bit.

 

What do you consider "all possible bolt on's"?

403s are a great set of cams and make good power on stock bottom end and defintely if you are leaving stock bottom end I would definitely do 403s, plus I seen 403s go to 180-190 with built bottom ends which are pretty good

I've seen 404's make 190, but never 403's. Got a chart or a link?

 

Mill your head and run a thin head gasket and rock 404 cams

 

If you don't want to rebuild the block then DONT get 404's.

That simple.

 

i have a 3" intake, 2.5in exhaust, 4-1 race header, blox intake manifold and throttle body, b&m fuel pressure regulator, underdrive pulley..

 

You'll stil need to upgrade your valvetrain.

 

on the way, one step ahead of u

 

"race header" doesn't mean anything, whats the company that made it.

 

wow wanna know anymore technical things? it has super america gas in it... and the header is custom 1 3/4 primaries and 2.5in collector. there u go!

 

well thanks for the info.. 403's it is!
