As long as you stay with their GM Performance parts you are good to go. Anything else, not so good.

 

but he's not in a gm warranty he's under a bank warranty

 

zzp stage 2 for sure, gm is over priced.

 

Exactly, but how are they gonna know i have stage 2 pulley and injectors? If i bought the gm parts it wont say something like zzp performance.

 

x2! also gmpp doesn't give u options and i think ottp stg2 is still on sale

well they might b able to tell if the pulley is like stainless steel instead of stock black. if they hook u up to a scanner they might be able to tell that ur tuned. but either way, ur not under a gm warranty so might as well go zzp for more power and save moneys

 

Okay so of i were to go with ottp would u recommend the kit or individual parts. And eithet way do i need a tune or no? Sorry for all the questions im a noob to superchargers.

 

def. get a kit thats where u save teh moneys

with a gm stage 2 belt and multiple pulley system (its what u would probably b best off with) its only costing u $362 right now IF you send in your pcm. either that or, if ur car is a dd, buy a pcm off somebody with the same year as urs and it will work.

OTT Stage 2 Kit

they load a 'base file' tune onto it to get you moving, getting officially, individually tuned soon after is strongly recomended.

 

I think im gonna hold off on the stage kit for now till i know more,for now ill get an intake and go for appearance mods.

 

i wud recommend an intake then full exhaust before you get the stage kit, its not necessary but if ur eventually going to do it you might as well do it before the tune is put on the car.
id also recommend piecing together the stage kit, i was able to get one put together without spending a dime, jus trading parts, all you need is 60lb injectors, find a pulley either 2.8 if u do some cooling mods, or 2.9 or 3.0 if no cooling mods, then stage 2 belt if u go with a 2.9 or .8, and spark plugs probly brk6eix or brk7eix. and find someone to do a custom tune. youll spend like 150 on the injectors and 20-30 on a pulley and 20$ on a belt if u wait for a deal or jus search enough then 30$ on plugs, so low 200$s in parts and then the tune which id say will run you anywhere from 200-500 but with that youll be much happier than gm stage kit and dnt have to worry about any mishaps with ur ecu in transfer to ott or zzp

 

this.

and this.

 

I was looking at ottp stage 2 setup, so if i went that route, should i go with the 2.8 mps or the stage 2 pulley? Also idk how the pcm info goes, whats the best route for a tune?

i would also go with the heat exchanger just for safe measures.

 

The 2.8 mps is a 5-bolt pulley system.

The Stage 2 is a 4-bolt pulley system, and is best for someone upgrading from GMS2. This way you only need to buy the pulley, because it will bolt right to the 4-bolt GMS2 hub.

Both will work the same.

 

i got the gm stage 2 belt and multiple pulley system. it was for a few reasons that i'm now forgetful of. its essentialy a 2.8. about the safest pulley size you can go.

like i said if you buy the kit, you need to send them your/a pcm. they load a base tuneo there tha you can rock for a while. eventually, i would recommend post on here somehwere to find someone who can tune you specifically to make ur car the best running it can be.

 

Okay so go with the 2.8 mps, is the heat exchanger a need with this setup. I am completely stock and just want the easiest setup like i said i dont need alot more power. And do i send them the pcm once i bought the kit.

 

YES the h/e is not ESSENTIAL, but suprememly recommended. that way you don't blow your supercharger.

theres a how to on here i'll try to find but with THIS heat exhanger it literally slides in from under ur bumper and bolts in. then all u gotta do is re-route the cooling lines a little bit to run through it and ur all set. its a real piece of cake and doesn't take longer than an hour if u know what ur doing.

 

And is it better to have a stage 2 belt or the oversize tensioner pulley? Or can i stick with my stock belt. Thanks for the responses i am new to chevy modding so i have no idea what im talking about

 

^^^^ you need the stage 2 belt if u get the mps. and no problem its not too often i'm able to help someone so i'm jumping on this one!

anyway heres the how to i was talking about

https://www.cobaltss.net/forums/how-...bumper-221176/

 

okay thanks, so if i just went stage 1 with bigger injectors would i need a heat exchanger. Looks like more work than i really wanna do at this point in time. I just wanna shoot for basic mods to put me at the 225 ish range.

 

You wont blow your supercharger.

The heat exchanger, and intergrated intercooler for that matter cool the charge air. They do not cool the supercharger.

The only way you can cool the internal blower temp is with water injection.

Heat exchangers are easy to install.

Read my "how to" that riceburner posted. If you have any questions feel free to ask.

 

I read there is a certain pulley tool you need to install stage 2, what is that all about?

 

whoops didn't mean to say 'blow' ur supercharger haha but yea its essential for cool IAT's which means it makes use of boost

ya just get a pulley tool from autozone its really not that special.

however, to get the stock pulley off (its pressed on, not bolted on) you will need a press to do so. you basically need to hang the s/c from something and push out the pulley through the rod its pressed on. easier to do than explain..

 

Yes, with the GMS2 pulley.

It is a tool for the pulley bolts.

The GMS2 "style" pulley OTTP sells comes from Smoothflow pulleys & does not use the GMS2 style bolts.

You can get the GMS2 style pulley in pretty much any size. Like I said before, the option is there so people who are upgrading from GMS2 don't have to purchase and install a new hub.

If you still have the stock press on pulley, you will need a puller tool to remove it, and install the hub.

 

turbo it and call it day

 

This is just gettiing more and more complicated lol i hate being such a noob

 

Stay on topic please.

It's really not that hard man....

Purchase a Stage kit (either OTTP or ZZP)

Select a pulley size (2.8" is most common)
Select larger injectors (60's)
Send them your PCM to get flashed with their tune.

Bam you just modded your car

If you need any help please feel free to ask me.
