I'm looking for a little feedback from you guys with stock GSR turbo's. I'm trying to put together a rough estimate in my head of my output, but the problem for me is i'm kinda in a unique situation in that I'm using a much smaller turbo that the T3/T4 crowd. Here's the setup:

Stock GSR
Revhard Mani
Straight T3 (.48 A/R hotside, ?? coldside but it looks like a 50rim?)
Revhard 2.5" DP (no cat)
Apex'i N1 (n/a) 2.36"/60mm exahust
Hondata S200

With a conservative tune or say high 11's A/F, conservative timing and 93 pump gas.. any guestimates? It's tough because all the dyno's I see show guys with T3/T4 60-trim+++ . I like to aim relativley low myself, so I was thinking somewhere near 230whp @ 10psi, but this is really a stab in the dark. If anybody out there has similar experience with small turbo's on stock B-series VTEC's let me know please

 

With having a gsr motor and that small of a turbo your top end with not be very productive.
I have a C5 and running a .60/.63 and i am thinking about going even bigger (stock motor). I'd say at least go with a .60/.63 turbo you'll make more power.
And at 10psi your numbers should be higher that what you posted.

 

Yea I already know its a small turbo, I made that pretty clear. But since it's all I have right now, I'm looking for any kind of input from those who've used small turbo's on these motors.

 

you'll have a much larger powerband at least. great for messing around under 90 mph. you'll make more than 230 i would think.

Hey that can be a good thing.

 

The 50 trim t3 is going to be maxed out around 250hp. You will be lucky to get that at the crank. Figure low 200's at the wheels.

I dunno about that. This turbo looks fairly larger than my GReddy and if I could pull 217whp on a D16 at 10psi on that turbo, I think 230whp is a easy shot for this T3 on a B18C1.. just me though.

 

if you are going to tune on a dyno, then you'll be able to run more than 10psi thats for sure. push it and you'll get respectable numbers. what size injector?? fuel pump??

 

With that little turbo you should be able to run 10-14psi with good tuning. I don't see much more than 230whp but I'm sure the tq will be pretty nice.

well a t3

damn your thinking just like me. I would imagen that it would make some very very nice power from 2500 to redline. Spool time should be no longer than 2700rpms! expect your peak tq#ers to smack you in the face at about 32-3400rpms!
It should pull hard all the way to readline

my perdictions on a stock B18c1, T3, hondata tuned....
.....7psi ....220whp with 170tq
hard to say really...... best of luck bro.
