ok so on my car right now i have 2.5 cated dp hv3 cone filter shift kit plog and ran a 15.3

and want to know what you think my gains will be by adding a l67 tb wich i got for free and poly mounts im hoping for 15.1 15 flat
 


you wont gain .2 tenths from ANY tb at your current mod level..if you decide to put it on your going to need to get it tuned and for the cost of that its not even worth it IMO
 
I keep telling you man...get a PCM. It shouldput you in the 14's right now if you know how to drive it and put the right fuel in it...as in 92 or so. You'd be better off just porting the stock L36 TB...and getting a MAF tune.

Or he could sell his car, save his money and time, and buy a gtp and run 12's or 13's

12's? are you high? Do you realize how much more money he'd have to put into it?

What he SHOULD do is top swap and cam his car. :th_thumbsup-wink:

Actually ya I was high, just saying save his money buy a gtp and put his money into that. A gtp is always going to be more reliable than a incorrectly done top swap!:th_thumbsup-wink:

Sorry, but this is the correct statement.

Actually bothered to do some research. Turns out with a stock crank pulley the Gen V M90 should only be run down to a 3" pulley. Any smaller and its no longer worth the added boost due to the temp rise. And thats what Eaton says...

So...... higher compression will take more advantage of the crappy M90.

15's? These car's get 15's?

If it makes you feel ANY better...my N/A auto stock 2.2 Cobalt sedan went 16.244. I think with poly mounts, a 5-spd swap, header, cold air, and a tune...it would run door to door with that GP. BUT...thats more work than I'd ever care to do...so I'm out.

Wow, that makes me feel better enough to get another job to get go-fast parts to insure that never happens.
 
GT, GTP, GXP,
I'm constantly getting confused here as a mid 2000's GT is supercharged while an older one is not.

:)

What does a stock GXP run in the 1/4?

After '05 they stopped making the GTP so the GT's were supercharged. The N/A ones were just labeled as "base". 97-03 were not supercharged. Shouldnt be much confusion there.

As for the GXP...depends on the driver. I saw a K&N CAI/Catback/DP GXP run 13.8's...so...maybe low low 14's?
