Just bought a t25, mistake?
 

Right now I have an IHI RHB5. I can pretty much feel this turbo make its max efficiency at around 65-6800rpms. I bought the t25 because it has only 30000kms on it. But now I am hearing they have no topend pull whatsover. Will it be faster than the RHB5, or shoudl I not even bother putting it on? I plan to run 9 psi.

Re:Just bought a t25, mistake?
 

it's gonna be the same thing as the rhb5 compare them in size and you'll see. sell both turbos on ebay and buy a .48/.60t3.

Re:Just bought a t25, mistake?
 

What IHI do you have now? For exsample one from a T-bird will do better then one from a probe, there not all the same.

Re:Just bought a t25, mistake?
 

If it was maxing out at 65-6800 what is wrong with that, what are you revving to?

I personally wouldn't buy a T25 to replace a IHI, there many be an increase but not worth the headache of moving evertyhing around.

Nothing wrong with a T25 in and of itself, but not a good upgrade for you. Sell both and get something bigger.

I have the probe RHB5 right now, reason to put on the t25 is because its like new, and probably wont burn oil like my RHB5 does. I am revving too 7000rpm.

The t25 looks bigger than the RHB5, when I forst saw it I thought it was huge compared to the ihi.
I am also thinking of putting on the t25 because the wastegate looks way better, my RHB5 creeps liek crazy, and I want to put larger exhaust and downpipe but I think with the rhb5 itll creep even more.
A local guy here made 205whp with a t25 on a d16z6, all i want is 180whp out of my d16a1 and Im happy.
Does anyone have any dyno #'s or 1/4 mile times with this turbo configuration?

Re:Just bought a t25, mistake?
 

Not exactly what you are looking for, but d16a6 with a t25 at 14-15 psi boost in an ef sedan with slicks. 13.0 in the 1/4. I think trap speed was 109 mph. Also, it was a stock bottom end. It was a friend of mine's car. The car pulled damn hard for a little t25.

Re:Just bought a t25, mistake?
 

Ok these are my goals,
180whp on a stock d16a1 runnign 10 psi MAX
The car weighs only 2000lbs so it doesnt take much to move it. I want it to pull exactly like the RHB5 with a bit more topend, and comparing the two turbos the t25 looks bigger.
This car is daily driven, not a drag car.

Re:Just bought a t25, mistake?
 

look up phresh_5's dyno stuff. He has a T25, Z6.

Re:Just bought a t25, mistake?
 

Thats actually another reaon I jumped on the t25, presh made awesome power with that turbo.
I think I just got discouraged because I searched up hondatech and all the rich ass mutherfuckers who are made of money "dont waste your time with a t25" they said the same thing about the RHB5, and I love mine, alot of them build there cars mainly for drag, mine is daily, it pulls like crazy with the rhb5, and im sure itll pull harder with the t25 (a bit at least) so i think im sticking with it. ;D

Re:Just bought a t25, mistake?
 

with a nice manifold, down pipe, and exhaust the t25 has top end! i picked up one my my 90si and i came across another for chape so i picked that one up too! they a nice turbos and if anything... later if you want more power you can upgrade to a 16g!!! if im not mistaken it's pretty much a direct swap!! it's a good upgrade fot the 2g eclipses... i'm sure it'll be just as good in a honda!!

Re:Just bought a t25, mistake?
 

Maybe you should also think about just swaping the compressor and housing to the IHI T-bird. That way you dont have to worry about a new manifold flange, or down pipe.

I made 167whp/188ftlb at 8psi with IHI probe hot side with T-bird cold. You should have no problem with reaching your goal at 10psi with that same turbo. Plus that combination does better in the higher R's.

Re:Just bought a t25, mistake?
 

From the sound of what you have, and what you want, the T25 will be perfect for you. Bambooseven has a T25'd y8 and it's a fun little street car. Not made for big top end drag style, but a T25 will give you that "zippy" fast around town your looking for.

Re:Just bought a t25, mistake?
 

no mistake.I have an ihi and a t25 from a 89 grand prix. the t25 looks alot bigger.Im running an integra with the t25 and the car pulls strong.spools up fast so off the line is to youre advantage

Re:Just bought a t25, mistake?
 

My stock 1st gen ZC with a T25 pushing 8psi i ran a 13.7 @107 on street tires spinning 1st through third. I'm using a ported vx mani and shitty fuel management.

Re:Just bought a t25, mistake?
 

That is amazing. :o

Re:Just bought a t25, mistake?
 

t3 biatch. a big one too

Re:Just bought a t25, mistake?
 

The T25 is definatly a bigger turbo than the RHb5 from the Subaru/Probe. However its not a huge upgrade and might not be what you are hoping for. A 14b (td05h) would be a better turbo to upgrade to, or a 60/63, 60/48 T3 turbocharger. All these turbos spin pretty quick on stock d-series.

Re:Just bought a t25, mistake?
 

Will the t25 have the same topend as an RHB5 from a probe?
And what do I need to swap the compressors from a tbird? Woudl a rebuild be necesary?
