I decided to buy a crower cam, valve springs, and retainer. But i'm not sure which stage to buy? Right now i have a stock d16y8 with an I/H/E I plan on getting a turbo or nitrous after the crower upgrade. Here are my choices from their site:

63441 Stage 1 - Features far more agressive ramp rate then stock with added duration. Excellent for turbo and nitrous. Idle to 7200+ rpm.

63441T Stage 2 - Designed specifically for turbo charged and supercharger applications. Features short duration and high lift. Requires springs and retainer kit

63442 Stage 2 - Street/Strip with slight lope at idle due to increased primary and secondary lobes. Requires 84166kit( retainer and springs) . 900-7500+ rpm.

I was thinking about getting the second stage 2 because it allows me to increase my rpm above 7500+. It says street/strip but my car is also a daily driver so i was wondering if i should go with the stage 1? I'm going to call crower tomarrow but i was wanted to know if anyone else is using crowers? Also does anyone know of a good website that sells these things any cheaper? I only looked at the crower site.

 

anyone?

 

Go with the one with the lowest duration. Turbo cams, by rule of thumb, should be moderate to high lift and short duration. Longer duration with blow the intake charge straight out the combustion chamber into the exhaust. Granted cam tuning can help this but the shorter duration is what you should go for. After all, look at the recommended cam from Crower themselves, they know what they're doing, if the Stage2T is designed for turbo than that's the one you should choose, if not at least go for something closer to stock.

 

We used the ls crower turbo cams in a fully built ls. Crower springs and retainers all installed having oem spec tolerances and crower valves lash specs. Made good power over stock. They are a very high lift cam. Bout 1000 miles we moved the redline to 8k rpm (well with in suggested spec using crower valve train) and the same day both cams broke in 4 pieces each. Both broke at the same time. Crower has good tech knowladge and make good power...but use and sell shitty core blanks and have breakage issues. Use crower at your own risk. I have not heard of sohc cams having issues though.

 

none. skunk2

 

WORD

 

crower cams and other cams that break are due to the base core having a bigger circumference. you have to replace the lost motion asemblies w/ the ones off the type-r. they have a slightly bigger clearance and they reduce the amount of restriction on the cams. web cams encounter this problem too when they make billet cams. use the search, and you'll find some discussions about this. as far as which ones to go with, pick the ones w/ the lowest duration, and lift. it's usually recommended for turbo use.

lol

 

no lost motion assemblies on an ls dude

 

I like the sk2 but they don't make a SOHC. Here is a link to the crower site: http://www.crower.com/cat/impo...shtml. There they have the durations. I want to be able to use a N/A set up and later go to a turbo but i'm not sure if i should use the Stage 1 or go with the 2nd Stage 2. The stage 1 bring the redline to 7200+ and the 2nd stage 2 go to 7500+. I want to have my redline be 8000.

 

bump

 

Oh ****, before I agreed with the skunk2 statement aI went to the skunk site and looked at application and the z6 cam was listed but I did not look and see that it is all TBA.....sorry about that...check out ef-1.com , rocket makes sohc cams

That's all goody good for vtec but doesnt explain why the LS cams broke. Maybe the base circle is bigger on the LS too?? Maybe piston to Valve interference at high rpm because the momentum of the valves-- HUGE dia. stem and head of valve.

 

I'm going to call sk2 and ask them when they are going to have a SOHC. I can't wait until they come out with there new intake manifold for the d16y8. If they are going to have one in the next couple of months I'll wait for the sk2.

 

ive never heard of a non-vtec crower cam break. did you check the cllearance of the cam caps prior to running the engine? the cam should move freely without the rocker arms in there...

also ZEX is supposed to make a real good single cam ummm cam

 

Yes triple checked everthing there was 2 check...cap clerances, valve lash everyting. I worked at a shop when I built this motor and I knew the reputation of Crower cams so I went through and checked everything. There was always a wierd sound. At first I thought it was piston slap from the forged pistons, but then if you put your ear to the distributor you could here it waz that. The reason the cams were triple checked was because of this sound. After they broke we put a vtec head on it and the soundes were gone. We even used the same distributor. When they did break Crower was called and he said he would at least replace the cams and possibly remburse for labor and head damage. Then he blamed the installer the next time we called him for really no reason, just trying to get out of ****. So I sent the broken cams and digi picts of plastigauge measured tolorances to the kid whos car it was and he sent them to crower. Never ever heard anything back from him. If any of us call he is not there, or is there till they learn who it is then gone to lunch or just stepped out or some ****. He basically hides. Can't even send out a new set of turbo cams so at least the kid can sell them. **** crower, I'll never buy anything from them.

 

If you woudn't buy crower what would you buy then? What about crane?

Personally I would buy Crower cams long before I would buy Crane cams.
