Well I got a 88 CRX with a B16. I got the weight of the car down to 2050 lbs with me in it/ I want to throw out about 240 hp to the wheels. A freind of mine wants me to buy a Garrett GT25. I am having a hard time finding the hotside info on it, but the compressor is a ar 60. Of course it is ball bearinf and it has ben run for a few hours. It also hase been setup for external wastegate and had a extension of the compressor outlet. I am kinda on a budget... and I know it will spool very fast. The motor will be just run off FMU and maybe something to control timing. I want to run between 8-10 psi

What are these worth and what kind of hp number to expect?




And the car it is going on

 

Its going to be disappointing is all i have to say. It might make 240 with a FMU but the power is gonna be really disappointing. If you'd like, PM me for local chip and tune when you deside to go boost.

 

Well, correct me if I'm wrong but you shouldn't really have a problem making that power with that turbo. I think the back is a .84 a/r. My roomate has one of those too. It might die out a little top end. I know the .48 have that problem but being that the back housing is twice that size its should be a problem. It will be a torque monster also. Good luck yo

 

You can't compare t25 and t3.

 

Hmmm well what do these sell for usually? And I mean used in almost new shape like this one?


rainmanef, I think you are right. I am sure it will not have the power at high end, but it should build tourque fast. A good amount of tourque will get you down the track quick, but a good high end turbo will get you down the track fast.
I paid $300 for the turbo.... got the homie hookup.

Number crunching says a 12 second pass is doable with the car as light as it is. And as far as the car on the street... well I think it should do just fine. I have about $3,100 into the entire setup... including the car.. motor.. turbo... EVERYTHING. So if it does a mid 12... then I feel I got my moneys worth

 

Tons of low end torque pretty much equate to wheel hopping and serious traction issues, not to mention the abrupt drop off in top end power with that turbo/motor combo.

Maybe a mid 13, but i highly doubt a 12, especially with no real fuel/spark control. GT25 @ 10psi on FMU, from what ive seen... power output will probably be more like 200whp.

 

Hahha 10psi on a gt25 and only 200whp. Sounds very dissapointing. Why cripple that motor with a fmu? what did it do to not deserve a good chipping.

 

cause I am going to stand alone. I have used and will prob use again, SDS.

And as far as times. I think it will do a 12. Power to weight ratio is there.

 

Anyone else?

I am also asking from personal experience, not assumptions

 

I bet most people are thinking

YOUR TURBO IS TOO SMALL FOOL

 

maybe..... but it is what i can afford. After looking at the map, I see it should not be too bad as long as i am realistic. i should be fine if I stay up to 10 psi. It should squirt out of the hole on the track. It should be responsive enough to where it feels like you are driving around on a 100 shot. I have no internals so I will lgo for something bigger later. I am not here trying to put together a HP.... but more of a well put tpogether car

 

A well put together car would have a turbo that you have because it meets your spec. Not one that you have because your friend randomly had it.

New t3 or t3/t4 hybrids aren't that expensive. Spend $500 and buy the right turbo.

I think its ok for a street low budget setup... I made 14.2 on 1/4mile with a similar turbocharge (T25G) w/rain tire, the turbo had a lot of shaft play on it with and missing 1/4 inch of each sector of exhaust wheel.
8 Psi in a 97 Coupe(full interior),B18b, no O2 sensor , no tuning and a shitty afc.
Dunno wut it can be with a B16a because of the high redline.

Well like I said earlier. Mathmatics say that a 2,100 lb car making 220 hp to the wheels, should do 12.36... in a perfect world. So after traction...reaction time ect... should be mid to high 12s

 

I was trying to find a compressor map to show you how inefficient that thing will be at 5000RPM+, but no luck. Why would you spend the money on SDS (which is totally obsolete in Honda applications), and skimp on the turbo? I'm not trying to be a dick, i'm just trying to understand why anyone would do that?

Did you watch pinks lastnight? What the hell was the fat kid thinking? Grrrr... WHY i ask? WHY!?!

Sso you are saying you cannot use SDS? If so... you are very mistaken. They make a system that runs off of the dizzy... or if you are willing to throw down the the cash, get rid of the dizzy all together and run DFI

I feel the turbo was a bargain concidering it's condition. Buying a used turbo over the net can be risky buisness sometimes. I really need something that is in good shape like this one is. Keep in mind I am not using this forever.... but just until I find what I want.

 

Are you sure that is a gt25, it looks more like a gt28. A gt25 should have a slip on intake not a bolt on one.

Anyway, I have a t-25 journal bearings on my sr20de se-r. I have hit 12s with it on street tires. It will fall off on my car around 7200, and that is on a 2.0. It will be fun, but limited.

Still think it is a gt28, check out apturbo.com and look at those to compare.

The b16 heads will outflow sr20 heads any day of the week. Without a compressor map its useless tring to tell you it will be way out of its efficiency.

I had a t3 60 trim on my SOHC and i even thought that thing was kind of dissapointing.

You friend probably found out the limits on that turbo real quick, and thats why hes unloading it.

SDS will work, but for the doe, todays Honda Rom Editors are light years ahead of SDS when it comes to efi tuning.
