1.9 zzp rockers

[chrisLB]

Are the 1.9 rockers worth it from zzp? Performance and HP gains? I've heard they can be noisy?

[Fivefingerdeathpunch]

they are noisy.

Gains are small, and most will say its not worth the money for what you get.

[gtpsleeper]

depends on your definition of "worth it" really

[chrisLB]

I'd like to drop down to a 3.2 pullie from a 3.4. I have headers, water meth and all the supporting mods.

I've got them and they helped get rid of my KR issues. Little more peppy too. Havn't noticed any added noise myself. If your going to pully down thay are a nice alternative to doing a cam.

[Fivefingerdeathpunch]

a good custom tune could get you there.

^^^this... dont be so worried about the pulley thing... if you make better power on a bigger pulley just leave it and be happy...

^^THISSSSSSSSSSSSS

Smaller pulley isn't always better.

Remember...with more spinning...comes more heat...and more knock...(possibly)...I'd be willing to bet a properly tuned car on a 3.4" with a meth setup and a leaner AFR/higher timing combo would crap all over a less than stock timing...pig rich 3.2" car...

I would love to see someone prove this. Every attempt I have seen resulted in the meth powered car being a complete turd.

ive heard from people on here that the zzp rockers break and then ruin the top half of your motor...idk if thats true and more people say that doesnt happen then people say it does but its just something to think about

[txslow6]

Hell yes 1.9's are worth it. I've had them on 2 GTP's neither were "loud"

I have never heard of this happening. The people who say that didn't install them correctly because the fact is that they are stock rockers.


Buy them used. You are getting them used from ZZP anyways.

I have them...It's not a huge gain but every little bit helps.

I think I paid $150 for mine. A good deal can be found.

I have some and they aren't noisy at all. Sounds stock. I'm running mine on stock springs too so i'm sure i have a lot of valve float. I have crow 105's in the garage but i'm super lazy when it comes to working on my own stuff lol
