I want to know about these cams? has anybody tried them? what are the goods? the bads? Tell me about them! Is it easy to install them and how much work would be involved. Im putting this into my stock motor, will it effect anything? do i need to upgrade anything before putting these cams in. If i do turbo my car, will this cam hold the turbo. Thanks and hope someone answers my question

What are the goods? - you have a HUGE improvement in low end tourque, which is most noticable, and a huge boost when ur mivec kicks in.

the bad? its not a "minor bolt on"

Easy to install? for a mechanic, yes... for a 19 year old... no. good thing is you do NOT have to take the head off to install it. slides right in.

Will the cam go good with the turbo?? yes it will go good with the turbo. But if you order the RRM turbo kit, make sure u mention on the phone u have these mod, maybe they can tweak the piggyback to accomadate for the cam... if not, would be a good idea to get the kit tuned around the cam. Not needed, but it'll improve performance.

if ur not going RRM turbo, u'll need to tune it anyway, so yea.

great mod, i think the most gains overall, other than the turbo. it really puts u back in ur seat with the extra low end torque

Ok Thanks, you answered all my questions. Thanks for the help and advice. If its not a problem, I was wondering what kind of exhaust I should get? I was thinking an HKS one..what do you think? or should I get something else? I dont want the magnaflow on the rrm site..its too small...the tip that is.

I have a quick question about installing the cam. In order to install it I'm assuming we have to take off the timing belt. Does that require to get all new tensioners too? Around what price range normally would you expect to get the cam installed at a shop?

If you're not due for a timing belt service, then no, you don't need to replace any of that. Get ahold of the Mitsu tensioner tool (I believe AMS makes one themselves) and you can use that to relieve tension on the belt without having to take all the covers off.

What size exhaust should you get???? this discussion has been discussed to death....

if your are staying NA or going turbo but staying below 300-325whp, than get the 2.25 inch exhaust... If your going to be pushing the turbo and getting max horsepower, than get 2.5 inch exhaust. alot of people here are saying to stay 2.25 inch no matter what. but that just depends on your power-goals. Generally speaking... smaller the diameter, the more low end power, but not much high end power... Bigger pipes and you loose low end tourque, but it'll open up the powerband to make the power at higher RPMs.

I'm gunning for 550whp so i'm going 3 inch eventually. but right now i'm 2.5. If i was just stage one turbo, or all motor, than I would have 2.25 inch. Like i said it depends.

Anymore insight on this camshaft? Install instructions maybe? and pics? reviews? any other supporting materials/adjustments needed?

ottomatic · Aug 20, 2009, 10:37 PM

anyone?

Just get the shop manual and it describes how to remove and reinstall a cam. Don't forget to do the valve lash. It is a job that a skilled home mechanic can do but it's definitely not a job for everyone.

i know this is a noob question, but im kinda a noob when it comes to tuning and computer related stuff...

I want to get the cam, but i dont know where to go to get it tuned :X there's not much of a tuning scene aroun d here in rockville INdiana lol

soulesswarrior · Aug 30, 2009, 08:54 PM

the RRM piggy is what u need to tune it. unless you go with reflash from hackish but thats up to you which route. if you go with rrm you could prob ask them to tweak it to accomodate the cam. as for exhaust Rock says stay with 2.25 if youre going na or turbo. but ask lsd said depends on your goals.

05lanceralliart · Aug 31, 2009, 06:19 AM

I am looking at the Cam for my next big mod but I was wondering if I install it does the car run a little messed up with out the RRM piggy or the Reflash? Is it normally better to get the Piggy or the Flash before does a bolt on like this? Sorry I know this is another nOObie question.

hackish · Aug 31, 2009, 08:04 AM

Although a reflash can adjust the rev limiter I've found the factory valve springs tend to float a little when you put a more aggressive cam in. I haven't yet had the time to look into better valve springs or lighter retainers. If you have everything apart for a cam then it might make sense to do the springs and retainers too. Obviously this requires some more mechanical skill and tools (such as a compressor).

Would you say the same with the RRM valvetrain?

hackish · Aug 31, 2009, 09:55 AM

Sorry, the only cams I've played with were the RPW and a custom one we did. I am not aware of any valvetrain components being available.
