Im interested in getting a stage 2 kit for my car, i want more perofrmance but i dont want to risk reliability too much. How are these things? Stage 3? its still an everyday driver keep in mind. Also, what pully sizes and injectors should i run?

BankerBalt

well there are multiple stage kits out there... ottp, zzp, and gms2 are the most common. it's all gonna be in the tune that makes it reliable or not. just get a good tuner and do whatever pulley you want. if you go lower than a 3.0, i'd suggest cooling mods though.

60# injectors 2.8" and get a heat exchanger and good tune

i know someone that went to a 2.8 on 42 ib injectors without a problem... might be a little risky for me but what does everyone else think? right now runnin a 3.1

Tjolley

Im on a 2.8 42# and nos no problems here.
Idc gets a lil high around 7200 but it works fine

newguy80

option b could help fix any heating problem right? and def need a good tune i would assume... using it as dd so idk how many times i would get to 7200

ZZP Stage 3....60# fuel injectors, 2.8" Pulley, Heat exchanger and a tune.....119000 miles and having no problems at all

Opt. B helps bleed air from the cooling system. So it makes the cooling system more efficient, but you will still need the addition of a larger heat exchanger & dual pass to really combat additional heat. Unless you plan to a run a meth setup.

newguy80

no plan for meth... as far as ik... just trying to gain power safely

So I stage 3 would be just as reliable as a stage 2 with the right supporting mods?

Yes.

KingOnso

What would you recommend for supporting mods?

JBros35

Intake, exhaust, meth kit, e85

KingOnso

Ok well I already have an AEM Cold Air Intake and GM Performance exhaust, best meth and e85 kits?

Staged07SS

You don't need both. Either go E-85 if it is available, or meth if not.

Def look into a highflow header/exhaust manifold & downpipe to complete your exhaust system.

Ok so if I get the ZZP Stage 3 Kit with #80 injectors E-85 tune I can forget about the meth?

Staged07SS

iTrader: (25)

Yes. Do you have a lot of E85 stations near by?

KingOnso

No, guess ill be going with the meth than. Best spot to install it?

If you do meth, you will only need the 60 lb injectors. Just an Fyi.

Search around, and research a bit. 100%METH is a good member to talk to about the topic as well.

Yeah I meant to say or but put a comma. Go devils own meth kit unless u have an e85 station near ur house.
