Tax refunds are the best when left in the bank and spend during the summer for upgrades, i have a funny feeling ZZP is coming out with more stuff.

This is great news for you and other people considering a stock K04 swap. Its nice to know there is a real option to go past the capiblities of the K04 and now have to start over with the rest of the setup.

Do hate your lsj. Just keep in mind there are many upgrade options for you!

That would really be the way to go here...despite all *reasurances*. A stock set up... even with pipes, clutch and IC will not survive very long over 425 WHP. Just my 2 cents.

Tax money was already allocated to this upgrade. ZZP is coming out with more stuff for sure. As soon as their LNF cams are available as a standalone package, Im buying those from ZZP too

The SAAB trans isn't from Sweden . Uhhh what ?

SRT4 guys have a fully built trans from them and thats a Mitsu part in an American shell , whats so different about this application , because it's not Japan Inc.?

One thing, you cant take wiki seriously. It is a horrible site to get proper and correct info. And yep Shep wont do the f35 tranny, some of the people here have tried many times. So me a link to where a srt shep trans is at

PrincessTurbo

I'm sure most are aware of that.

99% of the information on that wiki page is legit...

He used and adapter for a 1g but the old post had been deleted, still an adapter or anything they come up with would be a life saver right now.

Makes sense to me aswell....
Its hard to believe that at anyting around 400 hp that the car would be a great street driver.


I want to be at 400 hp and just need a clutch and that is it.

I want it to be a great DD still

this sounds liek a perfect option for me and I hope not too expensive.

I am real new to the cobalt world so this is prob a noob question question but do they make this for the 2.2L? becuz if Borg does I can get this for free.

This might be exactly what I needed to see to make me change my mind about leaving the stock turbo alone lol!

Matt, you guys at ZZP are awesome! I cant wait till you guys release this! I have one problem. Back when I was in flight training (Nov 2009) I bought all HAHN “bolt ons” :-( (My bad. At the time I did not know you guys existed, if I did I would have bought from you all ).

So, will the new EFR turbo work with Hahn cold air intake, charged air pipes, and down pipes?

PS….yeah yeah yeah I know I over paid for my parts. Lol I was impatient.

iTrader: (2)

theyll all work. I also have all Hahn parts that I bough in january of 09, it was about all that was out at the time for aftermarket parts. lol! But they said the intake might need some modifying but it shouldnt need much.

2 things what part of ct are you from? my gf lives in guilford and you'd have to get the stock ss/tc setup.. of you can get it for free for me and i'll pay you some bux lol

Thanks for the info. Turbo'dSS. Good to know it should work with any intake with a little modification.

One thing about ZZP's EFR has me bummed a little. I don't exactly understand why they went with a single scroll instead of a twin scroll. I thought a twin scroll would spool up a little faster and get a little more HP/TQ.
I remember reading that ZZP said it was only a slight difference, but wouldn't the twin scroll EFR be worth it?

Turbo'dSS

iTrader: (2)

i think that single scroll was the only option they had for right now. not 100% sure on that though. but it shouldnt be much of a difference in spool up, maybe like 500rpms tops difference, but with the EFR it already spools fast enough that if it spools any faster youll never get traction! lol! I was a lil bummed it wasnt twinscroll too, but for the power its capable of ill deal with it only being single scroll! lol!

Matt M

It would easily add 10 to 20k more up front cost to the project based on the development cost on a twin-scroll exhaust housing casting. Not many people would want to pay a few hundred dollars more to spool a hair quicker on a turbo that already spools very easily.

Matt M

It's definitely not 500 RPM difference. The last dyno chart shows 20 lbs of boost at 3200 RPM. Remember, this is on a turbo that made well over 500whp. Looking for 20psi at 2700 rpm on a 500+ whp turbo is unrealistic. I would expect twin scroll to spool 100 rpm sooner.

Ive never seen the inside of a LNF exhaust manifold but would it be possible to grind out the divider or is it not worth messing with?

blackbird

No, the Neon SRT-4's T-850 transaxle was designed for Chrysler and built by New Venture Gear (Magna/New Process) initially for use in the high-torque European turbo-diesel minivans and later in the SRT-4. It has plenty of support from the aftermarket as-is (input shafts, shift fork upgrades, etc.) and doesn't need to run a Mitsubishi transaxle. There's also swaps to Chrysler's older three-speed A413/auto that are popular with serious drag racers.

There really isn't too much of an issue running a conventional, single-scroll turbine housing on a divided manifold. You potentially do more harm to exhaust flow and create turbulence by trying to modify the stock manifold. A twin-scroll manifold and matching housing can be slightly more efficient in transferring exhaust energy to the turbine wheel but you're usually talking a matter of single digit percentages. By the way, here's a GM Media picture of the stock manifold (warning: ~2 MB file size).





Back to the thread, very nice power band and numbers so far. I've been keeping an eye on these turbochargers and having a stock-ish looking bolt-on turbo that requires minimal additional modifications to support that type of power might have me some day going against my plan to keep the Cobalt near stock.

ok, so now i can justify buying a used SKY or solstice
