Hey guys, just got a '05 Bonneville SLE and wanted to find out what the popular and most hp/torque gaining upgrades are on an non */C version.....

Well, for an L36, you can check out Intense Racing for their performance packages. If you've got the money, there is quite alot you can do to go a bit faster.

But as far as recommendations, rockers, intake, cam, just let us know what the price limit is.

Also, don't forget to submit some photos to the catalog of that sexy thing. I love those 05 SLEs.

If your looking to do rocker or cam upgrades n/a, ZZP has the best options hands down.

I strongly agree about ZZP

I didnl't want to go into engine mods. Wanted to see if there was room for exhaust upgrades, headers, PCM, CAI, plugs, stat or what would give me the best bang for the buck.... I sold me 2000 SSEI and the upgrades on a */C car are I'm sure more rewarding than on a non */C.

Got for a tune up, 180 thermo, CAI/FWI, high flow cat, and pems. Pems are plenty for a n/a car with no cam or valvetrain mods. After all that, a custom tune would be the best but a standard pcm would probably do the job.

Thanks for the input. I am familiar with all these mods but what is pems? sorry

Pems are ported exhaust manifolds.
