I was wondering if anyone has experience with running a turbo like this on a B20. The specs are the same as a 2G eclipse, so I know it is small. I want fast response/spool and I am running low boost. I was just wondering what I can expect. Will it spool "spikily" at part throttle. I am considering installing t-28 internals, what do you think. BTW, this will be on a B20 8.8-1c.r., 262 420" lift cams (Rocket's small regrinds) Skunk2 IM. I will be running 7psi. Please keep the flaming and nonsense about it being small to a minimum, I know it's small. I will be using an HKS manifold ( "no" it's not a dsm turbo ) and a 3" exhaust. Thank you for your help.

I don't think a t-25 is going to work on a b20. Sorry.

 

YEAH it will work .
you should get full spool in you B20 w/ the T25 @ about 3100 rpms. it will be a fun street car, but on the highend your power will die off.

 

Hehehe with that combo you should smoke anyone and everyone in little stoplight sprints! Would be a fun car -or fun CRV

 

FYI ive got a t25bb on my small 1.6 nissan motor...it spools really quick.

 

3100 is NOT EARLY..specially on a b20.
it will spool before that.

 

I get a full 10psi ON MY ZC 1.6L at 2800RPM with a mitsu T-25.

VERY fun street car, but even on my ZC, the power falls off hard up top

 

I would go with a t3/t4oe. The b20 will spool that baby @ 3k. However with the t25 there will be no lag what so ever.

 

Does anyone have any dyno plots of a B20 or other 2L Honda with a T25?

I'm thinking about this combo for a 2L GSR block for my autocross car. I've been told that a T25 would actually be civilized for autox and would be better than a JRSC for that app.

 

ID go for a t28!!!!!!!
it will spool super fast and provide some top end which the t25 DOES NOT HAVE and beleive me IT SUCKS with out any top end...

 

I am considering clipping the wheel 10/11 degrees and having the housings ported. If I can afford it I would go with T-28 internals. Would the clipping/porting help out with the top end fall-off? What could I expect to pay for these services?

 

Nice lawn mower turbo!

 

lol.
HOLY back from the dead..how ya been?

 

Most helpful reply ever...

 

Workin' my *** off. I finally got one work site but I still have 5 servers and way too many users to manage! Been driving around on an exhaust leak because I haven't had time to make my new 3" DP and exhaust. Still debating which beater I will buy when I take my car apart for upgrades... $300 EG6 with parts or $1000 RX-7 Turbo II with parts. I hate making decisions.

 

Ok... here's a lil more info


BB GT series turbos do NOT use T25 compressors. They use T4 compressors with the exception being the 2510. The non-BB T-25 will fall on it's face before the engine hits it's redline. When you do decide to uprade you will not only have to change the entire turbo but you will also have to change the manifold. A T3 is a better option because it has better flow characteristics and leaves room for future upgrades (T4/T3).

 

what B20 are we talking...?

B20a?

B20b/z or just a straight up CRV-Tec?

It will mater greatly, a B20a from the preludes would have no problem with a 2g DSM T-25 turbo, they hardly produce any ouput to begin with.

A stock B20b/z, It will work, spool will be incredibly fast, and you will get some decent top end, but it will start to fall off pretty quick.

Crvtec, well, I am definatly going to say No on this one, simply the turbo is just way to small for this application. The high rev's will drown out the turbo very quick. Your better off using a basic T3/T4 with a Crvtec.

This is on a straight B20B, 8.8-1 C.R., Rocket's small regrinds (.420" lift, 262 duration), Skunk2 IM. What's up with homemadeturbo.com?

 

glad your still in the game!

 

Have you considered a T28 from a Nissan Pulsar GTiR? They can eaily support 300 whp and will not die up top. http://www.store.yahoo.com/sr20perfo...arrettt28.html

Another option is the Garrett GT25. This is a ball bearing turbo and has a huge T04S (60-1) compressor. This turbo can support 350-400 whp and has almost instant boost!

Shift at 5k.

 

I have, but I don't know what to do about those damn extra parts I need to connect to the compressor inlet/outlet. Also, I got this turbo at a very cheap price, but I may sell it. I had talked with you about the GTi-R turbo awhile ago, and that is a decent price, but I didn't see those extra things to get to use it...

 

I can get you the o2 housing that comes off of the turbien housing. I shoudl be able to get a flange for the compressor inlet as well.

 

One thing I did gain from this turbo was an O2 housing that looks like it will work well in my application... hopefully. Does anyone know what simply porting the housings and clipping the wheel 11 degrees would gain me? Remember, I am only pushing 7psi, and my redline is 7200, I usually shift at 6500. Would these modifications let be breathe up to 6500?

 

you maybe dissapointed, do some more research on the turbo, it seems small for that size motor, .48a/r
