bored, just got a question .
Hey guys I got a set of brian crower stage 2 cams for my integra. Its a b17 a1 motor. I havent yet installed these and dont kno when i plan too. But Im just wondering what else i have to do besides upgrading my valve springs and retainers to brian crower or supertech. My motor has some bolt on's fuel rail, header, intake cold air, green top injectors off a h22 prelude, etc. I plan to run a different timing belt, cam gears adjustable to adjust when i dyno tune. What else do i have to do? a new headgasket? Thank's in advace i don't want too install these until i have everything i need to go with them. Rite now i have jdm itr cams.

to put cams in you don't need to change the headgasket... :wtf:
|
the head is gonna have to be pulled off to do the valves so ya he'll need a new one when he puts it back on.
|
Does he need to pull the head if its only the valve springs and retainers?
|
i dont think he needs to pull the head...just need to pull off the valve cover..
|
thanks guys. anything else u think i need?

how about freshing up your block, seeing how it's probably got a lot of kms on it and you'll need more compression to get the most out of those cams?

ya stage 2s on a stock b17 will be a little much.
You don't NEED to pull the head off to change the cams/valve springs/retainers, but its a lot easier to do with the head off, and if you drop a valve keeper into an oil journal with the head off, you won't have to drop the oil pan to get the keeper out. But i hope you've got the specific DOHC valve spring compressor that you'll need to change those valve springs (snap on charges $300 for the tool). I didn't see anything in his post about changing valves, so i don't know why he'd pull the head off. But IF you are gunna pull it off make damn sure to get it resurfaced and use a new headgasket when putting it back on. While its off and getting resurfaced, you might as well have them mill it a little more than just a .0005" resurface pass, tell them to take like .020" off and raise the compression up a little to get the most out of those cams. I always thought that stage 2 cams need at least 11:1 CR to be efficient. Running too big of a cam in an engine could actually make you lose power. |
thanks man alot for the great info its bookmarked.

i have the same cams, they are too big for that motor and c.r. but, you'll have to do with it. get that c.r close to 11.0/1 and acquire some good supporting mods. you'll need a good header (if urs is ----), mandrel exhaust, 3" intake system and a full tune. those BC2's have pretty much 12mm lift on both cams. Zman can take care of your tuning. i am personally done with Titanium retainers

thanks i have a 2.5 exhaust stainless steel to the headers. and as far as headers i got greddy 4-2-1 2.5 collector its nice.

Why are you done with titanium retainers? Not impressed with their wear characteristics after low KM's? Bad experience with your OMNI's?
my Omni's are cool, but, for the rigors of daily driving and the size of modern day cams.....they are not for me. my boys friend had catostrophic retainer failure recently. they basically sheared completely down and flew of the springs. luckily it happened when he shut the car off. another friend of mine saw significant wear after 30K. for dd, its not a wise choice. i have a new solution, modded OEM or CM. |
