I replaced my stock turbos with the garret t28 turbos and I was just wondering if any one has gotten 400hp or more out of them they are rated at 500 so I guess it has been done just curios as if any one on here has done it

Crank da b00st y0!

If by replaced you mean had T28 wheels installed into your stock housings, you made a horrible decision.

If you actually installed a T28 turbo, search. People have done over 400hp on stock TB02/22s.

I have 420 at the wheels with T25s. Thats at 20psi with just about every performance upgrade you can have without opening up the engine. After a performance tune I should be at 440-450. Running rich from the JWT chip about 10:1.

feathersem

they are a t28 becuae I was going to upgrade the wheels but my buddie said it would over heat the turbo or somthing along those lines so I got t28s and I didnt realize how much bigger they are but when I put them on I am just running 10 pounds and I went to the drag strip it ran a high 7 in and 8th and it wasent hooking up at all and before I ran a low 9 it may be that I have gotten alot more used to my car to I dont know

A JWT Sport 600 is approximately a T28, so the turbo setup is good for ~600bhp.

I hope you have supporting mods. (Injectors, intercoolers, full exhaust, ECU, etc.)

P.S. That's a smart friend you have.

Stronginchrist

Did you get a tune after the upgrade? Thats a big jump.

feathersem

no I am still working on it I got the computer upgrade from shoot i cant remimber the name it is a chip for the ecu I have a provec a greddy boost controler I havent got the injectors mod yet I am working on it though we are actually going to try and get it tuned in better after I figure out what is going on with my wiring I upgraded the pipping with a do it your self cheap kit i took it to work and welded it up any way give some ideals if any of you guys ahve suggestions that I can afford lol

You need injectors for those turbos. At least 740cc/min. If you turn up the boost at all, you're going to run your stock injectors to 100% duty cycle and likely detonate your engine when they can't provide enough fuel.

You do have at least a single intake, right? You should have dual pop to help those breathe... the intake T will be a bottleneck otherwise.

And I hope your exhaust is at least 2.5" from the turbo back.

As a general rule of thumb, X cc/min injectors can flow enough fuel for approximately Xrwhp. With T28s, you're definitely going to surpass 370rwhp. With my HKS GT2530s (which are only slightly larger than T28s), I was at 469rwhp.

I have the stock injectors I havent turned the boost up for the fact I am afraid of detonatation I have 2.5 inch exhaust I am going to try and get three inch I was going to do some resaerch befroe I do but I am confused on the intake explain wha toyu mean it runs from a single filter to the split at the mass air flow sensor then so on pluss I know the front mount intercooler is frownd upon but I have that

Stronginchrist

It sounds like you can just point and click on a performance list at this point Injectors; Intake; Intercoolers; Headers; Downpipes; Exhaust.

We'd have to know what you have to really tell you what you need. If you support those turbos you can really bump that boost up and make some good power.

Edit: Just read your post. I run 3" exhaust from the downpipes back but still have 2.5 coming down. No cat (shhh). I also have a front mount intercooler and it seems to work fine. Its better than stock so its not on my list of upgrades short term. Within the year I plan on taking Zlovers advice on the Stillen SMICs.

feathersem

yea I plane too but it is all about the money I just dont have it right now lol but when she comes out for ggod she will be bad I promise that

ZLover4Life

Twin Turbos don't have headers, they have exhaust manifolds.


FMICs reduce performance.

And what do you mean "explain what I mean"? It's pretty self explanatory... the two turbos are drawing air through the same intake opening... that's restrictive. A dual pop system allows each turbo to breathe on its own and reduces the restriction caused by the filter element.

Stronginchrist

Yeah but headers is so much easier to type

feathersem

I know they dont have headers I was just saying I dont have alot of money now any way I didnt get what you was saying but after you just said that I got it I just wasent picturing it right I guess the intake part I mean

Stronginchrist

I think he was talkin to me about headers lol

feathersem

o duh I got that now I guess I just have alot on my mind lol

zlover is saying. The "T" that spilts from your air filter is restricting air. You got two intake pipes the join togather at the "T". They gather air from one spot. Think about two spots .

Not to lead u away from zdriver but check this links gives a idea

feathersem

yea I get it I was wanting to get that style of intakes for that reason i new thay would help with air flow and power what do they do for the mass air flow because it is for a single remimber I am learning so be nice guys lol

You buy a second MAF and get a Selin translator to combine the signals (don't even need a Dual Pop program with the Selin translator). Search on twinturbo.net for more info on the Selin translator - the creator is a member.

ok thanks i will check into it
