a4 235-250rwhp. m6 240-255rwhp. dead stock. I have seen before and afters where a cold air and exhaust adds 25rwhp tho. They get to 300rwhp pretty quick.

I'd go LT's dump them at the axle with an x pipe. 1.6rr's, ewp, and a CAI. Your there, oh well and a pcm tune.

Slomarao, i see 1.6RR's are pretty popular mod, how much power do they usually give(with the mods in my sig) and how much is the install on them and which ones are the best to get, would i need any other additional parts to get them installed?. This is my 4th camaro ive had a 95 A4, 01 SS speed, 93 6speed and now a 94 6speed i love these cars and ive always wanted to put 1.6rr but never did meaning on the Lt1's not the SS.

1.6 rockers are good for mainly upper rpm hp. Id say 10-14rwhp and 4-5rwtq.

I think this time ill be doing the rockers for sure. Im pretty suprised that some people get high rwhp numbers, my 93 Z with shorty headers, no cats, magnaflow catback, exhuast cut out, pulley, air foil, K&N intake, Lightweight flywheel and Pcmforless tune pulled 266-289rwhp i put it on the dyno a few times. Last time i had it on pulled 289 uncorrected, once it pulled 284 uncorrected and 266-274rwhp were corrected. Hopefully on my 94 i can be higher in the numbers with the long tubes and 1.6 rr's. How much is usually the install on these and what parts other then the rockers do you need to do this mod? thanks again for the help guys.

Good numbers, my poor SS only got 250hp/290tq. But I'm in the process of fixing that.

its not how much HP you start with its how much you finish with (keep in mind dynos are not exact my car could make 276 on one dyno then make 250 on another)

dynos are good for before and after if you use the same dyno over and over

The first graph (blue) shows Hooker LT's, stock cam, stock catback. 266HP 305lbs/ft
The second graph (red) shows the result of adding 1.6 GMPP roller rockers, hotcam springs and Borla 3"catback. 290HP 315lbs/ft
The third graph (green) shows the result of adding the GMPP hotcam. 321HP 335lbs/ft

Disregard the third A/F graph. the wideband was not up to the task that day.
this was on my '97 M6 Z28 with a Strange 12 Bolt

I really would like to go the route of installing a hot cam kit but does anyone know a good reputable shop that wont damage my opti or anything else by installing this cam. How much does it usually cost. Sorry for the questions but not to sure how any of this goes, im just use to the regular bolt ons plus nitrous and im done.
