I know this has been brought up many times, and I know there are mixed opinions, but I didn't really find what I wanted to know by searching. I want to add a little performance, and as much as I would love to get a different cam, it's not going to happen. I just don't want to tear into my engine. Rockers are a little more extensive than I would like to do. Buy my question is this, if i absolutely cannot go with a cam, what are your opinion on the 1.8 Rockers? Some can be had fairly cheap, and in some posts on here it shows some pretty good gains, around 20hp. I already have longtubes, ORY, and a tune. I thought maybe this would be a good mod. Let me hear you opinions.

 

it depends . . . . some rockers will not clear the valve covers, or the heads . . . what brand did you have in mind?

 

Not worth it IMO. You're paying a lot of money for a little tiny gain.

 

Just keep on thinking you'd like more power and use that money on a set of tires when you wear them out in 60k miles or so. Even a mail order tune for 93 octane will get you double what the rockers would IMO.

 

 

I'm with them. there's no reason to get rockers unless you just have a badass engine that stock rocks can't handle. If you want to spend money on something get a cai, Tune, Efans, shift kit or something like that.
If minimal gain is your interest you could just by a tornado for your intake and another for the exhaust.

 

hahaha, couldn't resist could ya

 

Well when i searched i found a lot of information saying that people got like 20hp from rockers, it was even in a tech article. I've had a CAI before and some other stuff that supposidly boosts performance but they were pretty much a joke, just thought i'd check these out. Hell SUmmit has a set for 350 bucks

 

Is that an article for an LSX engine or a GenI engine?

Edit: on a GenI the roller rockers would actually increase the lift a lil and free up a bit of restriction, so you would notice a little gain. but on an lsx engine it already uses roller lifters and i believe already have a 1.8:1 ratio so there wouldn't be much of a performance increase. The only reason you would need to change them is to increase stability and strength. I'm sure i'll be corrected if i'm wrong, but that sounds about right.

 

stock rockers are 1.7 ratio
