i jus recently pulled out my t25 outta my b16. i pumped out 248 whp and 204 tq on stock internals. It does spool up real quick and i personally didn't like it for daily driving. I had a 8psi spring and it would boost up to 10psi at 2k rpm and then drop down to 7psi at like 7k rpm. So like what everyone else was saying, due to the change of a larger DP it had boost creep. i jus recently switched to a t3 and it feels real good. You can still retain the fast spool and it'll last you longer thru the rpms.

but if u want a full t25 setup, i got one and i'll let it go for cheap complete kit.

read a compressor map, its not very efficient at all for the b16 motor, especially with the 8200 redline. you will have alot of wheel spin, and after 6k all the t25 will do is run out of breath and act like a blow dryer and blow useless hot air into the engine.

I agree with everybody else use a t3, t3 super 60, gt28rs

a t3 .42/.48 at the very smallest.

You will still have tons of low end power.

I would still recommend something larger like a .48/.60 t3. There is really QUITE a big difference between top end power and not that much of a difference in spool time.

A T25 would be a great turbo for an HPDE/autocross type of application. I have no idea what these fools are talking about with it "choking off." It will hold 8 psi just fine on a lil' B16 all the way to redline. It might not have a HP peak at redline, but properly sized turbos don't do that anyway.

Mine would push near 12 psi at redline on my SR20DET(7500 RPM redline), and while it wasn't efficient there, dropping the boost to 8 psi makes it feel much more linear. A B16 in comparison won't tax it much at all in comparison.


I run a GT28R now, and I do have some minor boost creep issues because it can flow more. It will be good for a lot more than 8 psi on a B16. I run 17 psi on mine, so it could easily push that on a B16. Look up the compressor map, it can flow over 30 lb/min of air efficiently when well matched to an engine.

You Honda guys seriously need to learn that you don't always size a turbo going for big peak numbers and late spool like drag racers do. Sometimes it's much better to get a faster reacting turbo and give up maybe 10 hp in the last 1000 RPM of your powerband so that you can control the power delivery much better and actually get some midrange punch. It's all about area under the curve.

You've got a lot of good points, it's just that the t25 will deliver a lot of low end torque which is difficult to control on a FWD car, while a LOT more power can be achieved with a larger turbo higher in the powerband.

It is doable, yet it's just not that efficient of a setup.

Again, I suggest a .48/60. It will give great spool characteristics and you will be able to feed the hungry high end that the b16 has.

For the civichbcx kid : Your gay. With the t25 on your b16, your turbo will lose breath at about 6,000 rpm. Your redline is 8k, get a motec t66 turbo and a dual exhaust and call it a day.

here's an answer.....use the search function. but seriously, don't go smaller than a t3. i'm looking to use a t25 but with a sohc setup. if you're going to bother turboing a b series, make it worth it cause then you'll hate yourself in the end.

I want low end power, which means a T25 would be the logical choice for my application (reread my 1st post). Why do you keep talking like I want to run 10's? See, I told you, more speculating:

"You just dont want to run more boost or get a larger turbo cause you cant afford it"

Sorry my mom doesn't buy me my stuff, I work for it. Looks like your the one who needs to grow up.

That logic does not exactly apply to what you're looking for in this case because you're not just looking at the block, but the CFM flow of the B16 head is VERY different than most setups. That little turbo will putter out in no time, especially in the higher RPM band. It will be good to about 200whp at the most, and that's if it is pushed..

Come on, boost brotha's let's stay on topic.

I've a setup with a T25 from a SR20DET on a b18b and i loose my power at ish6500rpm you can put it on your b16 but i wouldnt recommand it.... go with a T3 if you want a quick spool and dont loose your power at high rpm.

Here in Germany a lot of guys run t25 on b16 with roundabout 10psi.
It is really a lot of fun and nice to control.
We made 238whp this summer. The la is nearly eliminated.
It is better to drive for daily than a high HPmonster - IMO

I'm a D series guy and have a T25 setup. It holds 10psi all the way 7200 redline from the initial 11psi. I'm not sure about the b16 but I love this turbo for my car.
