hi,
so i just heard of the garrett turbo kit to be released soon and i'm definetly gonna get this as soon as it comes out, however i still have a few questions :

1- i really want to make it just as reliable as any factory car, and i don't wanna get any issues from it so im just gonna keep it al 7psi until i get some serious money to do internals and ****, i heard it could run on stock exhaust and everything else but i still wonder if i should get any supporting mods as once again im not looking at all for issues!

2- Should there be any lag ?

3- i heard a whole bunch of people saying turbo cars were different to drive ( can't make extended trips, can't stay in 5th for hours, can't downshift like stock etc etc etc... ) so i just wanna make sure that i wont blow the **** up of it by driving like an ass. and last but not least :

4- how hard do you guys think it'ill be to install, like easier ( since it is rumored to retain all stock parts) or really hard, as i can't install a single piece myself as i got feets in place of hands i don't wanna go into a 3000$ kit and then 4000$ install for 50 ponies ...

Edit : And how much hp do you think i'll end up makin with an all out setup ( max out everythin )

brandisnez

not to be rude but I know someone else is gonna say it but use the search button and also you arent gonna be able to do anything without tuning...

Cobalt5533

Actually I'm pretty sure i heard someone saying garrett will have some way of tuning it ( if not why release it right now ?) and i did search but didn't come out with any satisfying answers

Witt

He is talking about a complete kit from Garrett that supposedly includes tuning. There was a thread earlier about it from their announcement at SEMA, but it got derailed when people began confusing Garrett's kit with the Maximum Boost kit.

1. If you run the complete kit on stock as designed, you should be fine with no other changes. If you wish to upgrade later, I HIGHLY suggest you buy a core engine and build in on the bench, then simply swap it out for your stock engine when you are ready. Don't take apart your only engine.

2. Yes, by design. But our smaller engines don't have as much as you might think. It won't bother you.

3. I don't know what you have heard. You should be perfectly able to maintain stock driveability.

4. Its not hard, but it is lengthy and requires and knowledgable person. Pick a good shop, and expect to pay for it.

If I didnt say it someone else would have

Cobalt5533

Tnx a lot Halfcent, and do you have any idea how much hp this could give at max boost ? or did garrett kept all of the numbers for the SEMA ???

Witt

Supposedly its using a GT2860RS. 7psi max, 200hp.

Not trying to be an ass as you must know much more than me about turbo ( real noob at this but i got enthousiasm and enough $ ) but why does this page says 360hp ???? And supposing im right, would it be possible to get a turbo with less max output ( no more than 300hp) so it would spool even quicker? nothing technical, practical or experience to back me up im just throwing this out and see what happens...

NJHK

Even if they did release #s, it doesn't mean you'll actually gain that much power...you could gain more, you could gain less. It all has to deal with your setup, how your specific motor responds to it and how well your motor is "tuned".

I highly suggest you read The Ultimate ECOTEC Related FAQ.

If you have any further questions, please ask.

NJHK

Max output depends on alot of things. Doesn't mean if you put a turbo kit on your car you will magically have 300 HP. There are alot of things that happend.

Like I said before, read the FAQ listed above and if you have further questions, please feel free to ask me or Halfcent.

Witt

It can handle up to 360hp if you want it to. It's limits are found on that compressor map on the page. That link isn't the kit itself, just the turbo used. Keeping the turbo in it's most efficient range is the object of the game, hence the turbo chosen.

If you google up some pages on reading compressor maps, you'll understand a little better why that turbo is chosen. It's all about airflow and pressure ratio. Basically, its a good choice for a turbo based on the airflow and desired boost pressure requirements of the 2.2L engine.

Witt

That should be made a sticky here, like in the j-body forums.

Witt

If you check out some other forums (j-body.org in particular) they have quite a few members who have turbo 2.2l engines. Gives a good idea of the results of different turbos and most importantly, how much boost the engine can handle before you are changing internals. I don't think any regular members around here other than NJHK have turboed a 2.2.

Edit: responding to a deleted post I guess.

Cobalt5533

what chance do you think the garrett 2.2 would have against the ss/sc?

Witt

IMO the stock 2.2 rods won't handle more than 250 crank hp. So should be able to take a stock SS/SC. Like I said, just imo.

Cobalt5533

hmmm strong smell of trade in for ss/sc... very strong smell....

Witt

Or be one of the first to F/I a 2.2

Cobalt5533

hmmm really gotta think about this ..... gotta sleep on it !!!!!

celicacobalt

i dont think 200 whp will beat a stock ss/sc since they are putting out more than that to the wheels but maybe stage 2 version of it will be the ticket to compete with the 2.0's

Cobalt5533

there's gonna be stage 2 turbo ????

NJHK

It is actually lol

NJHK

Typically "stages" just means that one kit will either lack item(s) or add to. When you start understanding how a full turbo system works, how it effects your engine as far as performance, then you'll start understanding that "kits" mean nothing but just labels for companies to advertise out to consumers. When you recognize what you need, you'll understand better of whats going on.

Witt

rofl, goes to show how much I read stickies.

NJHK

Its all good
