Okay guys, I am ready to slap down the bucks to get a 2.4 turbo system and 3" cat-back exhaust for my automatic Cobalt SS. I have taked to both companies via phone and e-mail and have gotten some positive and negative impressions from both of them. It's alot of money to spend so I want to know that I am putting it in the right place. Who do you think I should go with and why?

 

ZZP, better parts for the money, cheaper, has full evidence of their results, including timeslips, videos at the track and dyno videos.

 

QTF. easier to up the power in the future with the ZZP kit if you ever decide to (and im sure you will, even if you dont think so now) also, best 1/4 time posted to date? cmon

 

hahn is wayyy bitchin.
their exhaust's sound the best, and their turbo systems are the most popular...(so ive seen)
thats just the way i would go

 

Hmm seems Hahn is pulling away in the poll results

 

ZZP has had a few negative posts in the past six months, I.E. Quiet Resonator and Flex pipe, but they have fixed most of those issues and their turbo kit is probably going to offer more power at a cheaper price.

I'd stick with ZZP, you can't beat price/performance of their products

 

hahn has more of a rep so ur paying for the name, doesnt mean its better quality. ZZP is up and coming, hit a few rough spots but have hit the nail on the head with their turbo kit, why pay more for less, doesnt make sense

 

bro go with the turbo zzp thts wht im doing

 

ZZP is cheaper. But I'm sure it's at least decent quality.

Basically, you can't really go wrong!

 

hahn makes nice stuff but their tune file they send BLOWs and it's nothing special really you're paying for the name WHICH unfortunately means you're OVER paying .. their catback is really nice .. but it's a price to perfoermance and quality thing like someone said before ZZP really hit the nail on the head for this one

 

any of you guys actually have either of these systems?

 

i doubt it .. but i've talked to a bunch of people about the hahn setup who have it or have worked on it

 

im getting zzp. got half the cash already. just saving the rest. it looks really promising and theyll customize it to how u want. im getting a sort of modified stage 1

 

In the middle of installing the stage 3. No real mechanical experience and the only problem I've had so far was I couldn't get the turbo behind the engine, so i just rebuilt it behind

 

zzp?

 

zzp also uses the same turbo that is on the LNF ^_^

 

The lnf turbo is dinky.

 

The turbo is fine for our fueling system for now... We can't even max it out due to the fuel wall we hit.

but after it's unlocked... yes the small size and quick spool will be a burden!

 

Ima say straight up if ya got the money go hahn that turbo is nasty!! i was just watchin videos of one puttin it to sti's and a couple srt's really bad!!

 

how many people have hit a 12.1 on street tires with the hahn kit?

 

I'm leaning more towards ZZP's stage 2 kit. Less wear & tear than the stage 3

 

I say go with Hahn all the way

 

Actually before this gets too out of hand, ZZP uses the bullseye s256 turbo made by Borg Warner the same company that makes the turbo for the LNF. I don't think they could have gotten 200+ hp from the dinky LNF turbo on the 2.4L

 

QTF!

Some of these guys dont know what their talking about, same turbo as an LNF? right

you mean less hp lol. daily driving with the stage 3 compared to the stage 2 wont make a difference if your not going wot all the time.

stage 3 just supports more hp, u dont have to turn the boost up, atleast then you have the option to up the power further with that kit

 

i think what the person who said that was .. this is the same turbo they're using on their lnf turbo upgrade
