some more power for my z

[myzisbetter]

so i got my car dynoed.290 hp and 300 tq rw. since then ive done the free air mod kn filter and slp lid.im doing the LM system tuesday .where do you think ill be after all that. and how hard is it to port the tb yourself. thanks guys ......

Dont even waste your time porting your Tb. The stock Tb will hold you clear over 500hp so it wouldnt even be worth the hassle. Look at some lt's, ory and maybe a tune to get some better numbers.

ok sounds good.as for the lts and ory are they 50 state legal...remember i live in cali the land of the smog nazi's

Best you can do in Cali is mid length headers. Long tubes are verboten in the land of the smog Nazi's, as are deleting or moving the location of the cats (i.e., ORY = no go). You can do a cat back and a tune. IMHO 290 is kinda low for a 2002. Stock I dynoed 306/323. How many miles are on your car? FYI: Nothing is illegal til you're caught. But if you're caught in Cali be prepared to face loss of vehicle. 01-02 exhaust manifolds are pretty free flowing. Might be a wash except for the weight reduction.

I'm lucky. NO EMISSIONS WHERE I LIVE!!!!! LT's and ORY for me!!!!

[myzisbetter]

well i thaught 290 was ok.its got 80 k on it and the guy said i had a bad ping at about 5 grand.i could hear it too.he had told me to do a good tune up and the ping sound could even be from a clogged fuel filter.ill look into it..........ill get a tune next time i hit the dyno shop

Also, if you have stock gears, you might as well swing for some 4:10's for better acceleration.

4.10's work well with an M6. 3.73's work well with an A4. I have 3.73's as I have an A4 car with 41,xxx miles on it. I also have a Volant CAI, QTP 1-3/4 LT's, !cats, !AIR, 3" ORY, 3" E-cutout in the I pipe. Car put down 343 rwhp and 357 rwt on the dyno earlier this year during tuning.

More/future changes: 3" True duals w/ Magnaflows. Later: 3400 stall......

if you have LS6 manifolds dont waste your money on mid length headers
