Roller rockers?
I plan on either building or buying a CAI soon.
Which rockers would you buy?
I want to make sure I never have to open the valve covers again after installing too.
I will eventually buy headers but from what I understand, you lose back pressure and the cars seem sluggish unless you have a cam or rockers.
07 GXP. 37,000 miles.
Thanks,

2. The yella terra rockers are great but they are expensive and not made anymore. I would probally go with a 1.85 rocker as you will gain a little more then the 1.8.
3. As far as the headers go, its the second biggest mod we have. The first is getting a new intake manifold. Replacing the headers will give you very big gains, and the loss in back pressure is not a bad thing. It could be a on a turboed car but on a na its not.

also I have never had a problem with my comp. springs and they have been on there for a good while now. To be honest this is the first I've heard of it, but I also haven't been doing research either.
Finally, I agree with the headers statement and it wakes up even more when you swap the intake manifold. But remember you absolutely need a tune after a header install, there is no way around that. Also in case your wondered, you could never run the thorleys on a turbo set up anyway because of fitment issues.

Granted I'm not getting the full potential from my mods right now, but it's not a must.
