I have begun the quest. What is the difference between a T25BB and a T3/T4 turbo? Which would you guys suggest? I found a new resource.

T25BB Sounds like a GT25, which is a Ball Bearing T25 similar to what came on the turbo eclipse stock. The GT25 is good for up to 310 HP in various configs. That or a GT28 would be my choice for a turbo Accord. The T3/T4 is a hybrid that uses a T3 Turbine housing for less restriction, and a T4 compressor section for more airflow. It's too large for a 2.2l, but cheap and readily available. There are also more cast manifolds using flanges for that Turbo though, so if you can't get a GT2x turbo with a T3 flange, get a GT3 with smaller trim options for quicker spoolup, cause everyone knows Hondas need down low TORQUE.

 

After reviewing the link, I'd recommended the Extreme kit. For a 30% increase in power, you can just go with an H22 swap. I'd get higher flow injectors, 2.5" exhaust, and a Hondata for that extreme kit though. I don't trust those bolt on injector thingies.

Oh yeah, the BB turbo provides quicker spoolup and longer life.

 

GT25 is what i have to stick on my Accord, it should be a good size for it and should spool up hella quick...looking forward to it

EDIT: T28BB and GT series are different things, the 200sx/silvia comes with a T28BB

 

What else is different besides the sizes?

 

So in theory the T25 spools up quicker than a T3/T4. But which one will produce a nice amount of power without having to boost insanely. Looking at about 10-12lbs.

 

I'd go with the T25. the T3/T4 flows enough air for something like 400+ HP. That right there should tell you it's overkill on a 2.2l engine. The T25 supports 210+ HP with little to no lag. If you can, spring for a GT25. That will hold boost better at high RPMs.

 

Yea but the majority of people that I know have T3/T4 turbos. It comes standard on most Turbo kits.

 

my hks kit came with a t25.

instant spool. No lag whatsoever. I love it where all these ******* kids on these forums are all like "no dude its too small maing it wont work i ran all the numbers on my fuel map and boost conversion maps!!!!" or some bullshit theory ****.

Just put it on and drive, stop ******* with it for an extra 10hp and just drive.

 

I think i've asked you this, but what have you dynoed in at?

Dyno is booked up and I'm busy with work, but I can tell you it will be a helluva lot higher than what ive hit with nitrous, and those #'s were 174hp and 192tq on a 55shot. (Zex kit)


I'll get there when I get all my school stuff finished. School comes before cars.

 

We have those kits also... call us with any questions or send us an inquiry

yow!! Looks like prices for accord kits haven't dropped yet..........they look really nice though!!

 

Easier to piece my own kit together and cheaper.
