Does anybody know what trim size or how well this turbo would perform. It would be in a fully built 2002 cavy with the 2.2 ohv in it. Any other suggestions on turbos and sizes? Thanx for the help.
horsepower is the force that determines at what speed you hit the wall, torque is the force that determines how far you take the wall with you after you hit it.
Which one?

The kit i was thinking about getting just says a garrett t28bb. I honestlt dont know which one. what do you suggest?
horsepower is the force that determines at what speed you hit the wall, torque is the force that determines how far you take the wall with you after you hit it.
I also found the people over at ATP turbo to give you decent suggestions on that, mainly based off of what HP numbers you are trying to lay down.
you should have product or "serial" number on the turbo somewhere, its one of those "471171-9" numbers. Find it and then look at the list of turbos on the site. If you don't find it then it's probably not on their product line anymore...cuz find my turbo on there site and I have a t28 garrett.
no more cavy...now 240 =]
I see a cool-air intake
It's got a NOS-fogger system and a T-4 turbo
I see an A.I.C. controller
It has direct port nitrous injection
Yeah, a stand-alone fuel management system
...Not a bad way to spend $10,000
So heres the scoop, I got a hold of the company and the part number they gave me was 466541-0001, and if i looked at garretts website right, thats a t25, not a t28, but anyway i wanted some advice on what people think of the turbo. Is it good with our cars, bad, ok. Im one of those people that can put anything on a car, just don't ask me to tune it or understand what works with what. Im working on that though, so those that have constructive criticism please share, those of you that think im a stupid noob and should know everything can suck my middle nut. Im here to learn. Thanx to those who are willing to help.

they are t28 turbos, but they are all t25/t28 flanged, which is all the same thing.
what hp numbers are you going for and how fast fo a spool, if you ever need any prices on anything go through me, i have an account with ATPTURBO and i can get you everything for cheap, i will save you money. let me know the power range you want and i will help you out.
all gt28 turbos spool very very quickly and are available with countless options
examples for each turbo:
the gt2554r (gt25r) is rated at 240hp
the gt2560r (gt28r) is rated at 310hp
the gt2860rs, which is more commonly known as the gt28rs disco potato is rated at 350hp
the gt2871r is rated at 400hp
and finally the gt2876r (gt25/40r) is rated at 450hp
every turbo in your list are dual ball bearing turbos and are all t25/28 flanged.
i hope that helps you out a little bit
i think the t25/t28 are kina the same...same flange for the exhaust. I have a t28 and everytime i look it up I see alot of t25's and other t28's with the same flange as mine. Good luck getting a manifold if you dont already have it. I decided to get one of those ebay mani's and an adapter for the flange cuz the manifold has a t3 flange.
As for if they are good or bad...to my understanding...and anyone correct me if its wrong but, it depends how much boost you want to push and where you want the power....small turbos are good for low to mid-range RPM's, have lot less lag for spooling because of their size. t25/t28 turbo's aren't as "efficient" in the top end as a t3 or bigger.

^^^ on the comment about the manifold, APT makes an exhaust housing for many of the gt series garrett turbos that is a "drop in" design for the T3 housing, that has the ford style 5-bolt flange for the downpipe. Which is nice if you have someone offering to order for you at a discount....where were you when I ordered mine??!!
But as far as the performance of the turbo itself, it all depends on the setup, and what you are looking to get out of it. I personaly like all the GT series ball bearing turbos, thats why I got one.....
actually it is really easy to find a t28 flanged turbo manifold and even easier to have one made.
I found it hard to find one already flanged that way. I think IPP performance sells a cast one made by turbo specialties though. I already had my j-tuners mani/downpipe, that I was going to run a t3/t4 on, but changed my mind on the turbo....so the "drop in" was the best for me, but the wastegate flanges had to be slightly modified to fit right.
The company i found the turbo kit from is importperformanceparts.net please tell me what you think. Also, what does trim tell you, what is it?

oh, and im hoping for close to 400 horse. I have a list of parts i want to put into the car, including low compression pistons, h beam rods, stage 2 port and polished 3 angle valve job head: ill get the website tomorrow, all new gaskets and bearings. Ill get details in a day or two. But i am hoping for close to 400 with a fast spool and try not to get above 15 to 20 psi of boost. Let me know if im finding the right parts or if im way off.

and dont forget i have the 2.2 ohv, the cam in block motor. just to make sure you know what im talking about. And the car is a vin 4. i dont konw if thats of any importance, but what ever. thanx again for all ur help

^^^good luck getting it to 400 ponies. IPP's turbo kit isn't bad, I am NOT a fan of thier fuel management included in the kit...but it SHOULD have a nery nice cast turbo mani for the 2200 (yours IS the 2200, and not the older 2.2L correct?)
^^^^^ its a 2002 cavalier so ya, its the 2200 ohv. And i know it wound be easy getting close to 400 but thats just what im hopin 4, im not expecting it to get that high, but definatly in the high 200's to low 300's, maybe even mid 3's. i wont know till its done.

2002 had both the 2200 ohv, & the DOHC ecotec available that year....so it is really either or on that year. I am almost done with my 2200 build which is pretty heavy duty, so well see what kind of numbers I can lay down with it...I doubt an off the shelf kit with not so good fuel management will get you there....maybe mid 200's (which is still pretty good compared to stock...)
well im not just doing the turbo kit, and i would obviously change certain things to beter parts. but ya, let me know what kinda numbers you put out. what r u all doin to it?
horsepower is the force that determines at what speed you hit the wall, torque is the force that determines how far you take the wall with you after you hit it.
^^^^to give you a quick run down, fully built bottom end (forged pistons, rods, & fresh machine work all around), comp cam, cometic head gasket, ARP studs, p&p head w/1:6 roller rockers, oversized valves, chromoly pushrods, rsm intake & tb, underdrive pulleys, 500cc RC injectors, 1:1 rr fpr, MSD inline pump, Griffin rad, Garrett GT3071R on J-tuners mani, tial 38mm wastegate, 29x10x3 FMIC w/ 2.5" piping & Greddy BOV, Catco direct fit high flow cat, 2.5" exhaust, Spec stage 3 clutch, Fidanza flywheel, Phantom Grip LSD, AEM Uego wideband, HPT pro, MSD programmable Dis 2.....you get the idea....
vvvv there is a (really bad) pic of it on the engine stand, you can see a small gap between the manifold flange and the wastegate, that has been attributed to the "drop in" exhaust housing made by APT, but that was an easy enough fix...
The engine is now in the car....waiting on a few more parts to get it up & running.
^^^^^ wow, lots of stuff. about how much did that run you. What i figured for myself was about 6 grand give or take.
horsepower is the force that determines at what speed you hit the wall, torque is the force that determines how far you take the wall with you after you hit it.
^^^^Way to much....that is all I will admit to. 6 Large is a pretty decent budget, you can do a decent amount with that.....what other than the turbo kit are you planning on doing?
I'm planning on building a second motor so i can drive the car while the motors being built. Ima take a block, align hone if its not new. eagle connecting rods, low compretion pistons, clevite bearings, crank, a head from competition products. Its a stage 2 port and polish with oversized valves and a 3 angle valve job, a turbo cam, a turbo kit from import performance parts. a throttle body spacer, bigger throttle body, crane pushrods, crane roller rockers, fel pro headgasket, apr head studs, cv axles from driveshaftshop.com, tokico adjustable coilovers, plus anything else i can think of. Anything you wanna add to my list or change parts. What do you think. Im kinda new to this whole tuner thing. Its also crossed my mind to convert it to rear wheel drive. That would be so bad @$$. But i just started thinkin about it so its not offitial. Let me now if theres anything i should add to my list and where to get it.
