should i go with the gm stage 2 kit with custom tune or the zzp stage 3 with there tune? i think they would about be the same because its the same pulley size and same injectors

 

Just build your own kit and get a custom tune

 

i'ld have to agree.

just get what ever pulley size your mods will allow, i'ld go ahead and get some 42's, and then a custom tune for the type of driving you'll be doing. ie WOT, or just efficient power for DD

 

^^^^^x2 build your on kit, 60# injectors, 2.9 pulley, custom tune FTW!

 

I'm savin up my money for 12k miles till my warranty is up. then i'm buyin (this is the current list hahaha)
cobra or cx h/e, dual pass, option b for dual pass, meth injection, injen cai, 2.7, 60"s, 3" custom header back exhaust(w/ header of course), stage2 axels, 50 wet shot, valves, valve springs and retainers, comp cams intake and exhaust, and more than likely a cnc ported head. with a dyno tune

Till then it's still just a daily driver

 

how are the intake temps on a 2.9? i just checked on zzp to make my own kit and with 60# injectors wiring harness shortened belt and pulley with hub would cost like 400

 

You can get injectors with a harness on here from someone for around 200 or less, you can get the belt from CED for 45, and you can get a pulley and hub from Smoothflow for 90

 

thats helpful but still how are the intake temps on the 2.9 can it be much higher then the 3

 

It has been about 95* around here the past few days and the hottest post blower temp I have seen is about 145*

 

No they arent much higher then the 3, many people run 2.9s without any problems. Im personally gonna be running a 2.85 and 60lbers with a custom tune.

 

so with the 2.9 i should go with the 60# right because i heard that the 3 almost maxes out the 42# the price difference is only like 20 dollars so i would rather be safe then sorry

 

Thats a highly debated question on these forums, but yes most charts show that the 42lbers are or are almost most maxed on the 3, but many run a 2.9 and 42lbers with no problems. But either way getting the 60lbers is a better idea just to play it safe and if you want to go down in pulley size later on you will not need to buy injectors again.

 

thats true because i was thinking for in the future getting a menthol kit and going with a 2.8 or smaller
thanks for the help guys

 

what about using a return style fuel system on a 2.9 and 40's??

 

No problem, meth is a great mod for these cars no matter what pulley you are running

 

custom tune is the way to go unless you worried about warranty and stuff

 

custom tune x a million. Get all the cooling mods, heat exchanger, dual pass, meth, and then 60lbers and a 2.7inch pulley and a tune from a shop you trust.

I also recommend buying some gauges, like an interceptor and a wideband.
