Does any one have these? i'd like to kno how they perform before i buy them. Im lookin to buy cams for my SS. or does any one have any suggestions on a pair of cams to go with.
the link to them is http://www.gravanatuning.com/applica...ft_Set_Stage_3

 

wheres the stage 1 and 2 lol?

 

lol, i dont kno. thats wut they had on the site. lol.

 

They won't work in a 2.0. They are listed incorrectly on Gravana's website.

 

oh, ok. wow, thx. u just saved my car. lol

 

They will fit, but your PCM won't like them. The reason is, those cams are made for a 2.2 Eco. The exhaust cam on those is shorter and won't be able to turn our cam position sensor. You COULD install them, make a blockoff plate for the CMP, and turn the check engine light off (not disable) the DTC with HPTuners. You would then have to deal with 15-20 second cranking cycles 50% of the time you try and start the car.

If you really want cams, find a set of stockers and send them to Crower and they can do a base circle regrind to any spec you want. Runs about 200-250 bucks.

Edit: the guy that reground my cams for me will sell you the same grind, check my thread on the redline forums.

 

ok, thx. Wut grind is that? and how much. where can i find a set of stockers? lol. how does your car pull with ur new cams? is it worth the price?

 

Its a custom grind to the specs of an HKS EVO 272. I have a thread I started here that compares stock specs to those.

Stockers can be out of a junkyard, someone selling them, or your dealer. If your car isn't a DD you could send yours in and be down about 2 weeks while they grind them.

Car pulls like a freight train. They were a bitch to tune the idle, the electronic throttle is real lazy when it comes to idle tuning.

I love them, I couldn't deal with the airflow limit of the stockers, so yes, to me they were worth it.

 

how did u get the idle tuned down? cuz, i dont have alot of money, i need to kno wut im getting into first. wut would i have to do once i got the cams back and installed?

 

I had to raise base idle spark, then use a progressive ramp for idle corrective spark to allow the PCM to use spark and not the throttle to correct any variations in idle, but not so much spark to where it was constantly correcting. If you've never used HPTuners you'll have to have someone that has do it for you (local dyno/tuning shops that specialize in LS/LT1s are great for this).

If you don't retune it, your a/f ratio will probably be still pretty close since these are MAF based cars, but your car will probably stall everytime you come to a stop, especially with the air conditioning on.

Camming these cars is a lot of work and money, its a good idea to also change valve springs at a minumum as well to handle the increase in lift. Cams aren't exactly a bolt on and should probably be done only if you run out of bolt ons to throw at the car and still aren't happy with performance or have serious plans to run a larger compressor or a big bottle.

 

ok, are the springs all i need to replace when putting these in? i dont have a redline fourm name. do u have a link?

 

Hey, my dad does a lot of work with comp cams. I could have him look into maybe getting those for "buddy prices" which will be significantly cheaper than.

 

nah, its straight, I'd like to have the pros do it. but still in a good price range

 

kk...he does do a lot of work in aftermarket. So if there is anything, just let me know and ill see what i can do
