Turbo Help Please
 

Ok So i'm putting a turbo on a 1995 chevy s-10 2.2L 4cyl
I'm running 9 to 1 cr (prity high I think) I narowed it down to two turbos, and I dont know what would be better.
Here they are: Garrett T3 (.48/.42) or
Garrett T3-T04b (.48/.60.)
Can someone make a suggestion or tell me if there is a better turbo out there

Thanks
Larry

there is a straight T3 off a t-bird 5spd that is .60/.63

get that one. with a 2.2 liter keep above a .50 a/r or your gonna spool to fast..

hrm whats the redline on that motor?

Re:Turbo Help Please
 

I think they say it redlines at 5500 but I only take it to 4500-5000 at the most. I would like the turbo to start to boost at about 2500-2700rpm and reach full boost over 3000rpm

9:1 isnt that high.

Re:Turbo Help Please
 

What does A/R stand for?

Re:Turbo Help Please
 

I think its AIR RATIO ???

Re:Turbo Help Please
 

area/radius


basically its what determines what you spool at. (hot a/r)

the bigger the a/r the higher itll spool.

a/r is how big the gap is inside the turbo when the exhaust hits the fins.

SMALL A/R (.40)

BIG A/R (.60-.80)

Ok thanks alot for that I had no idea what it was, I kinda figured it was the size of the air intake.
So at what rpm would a t3-t04b .48/.60.
Start spooling on my motor just approximately ? I was told that that one would be perfect. But that was from the guy I was buying it from.
I just took my truck out for a ride and I wont it to start to boost at about 2500-2700, And I got it to 5500 rpm but I didnt like that. to much for the old girl lol.

well u say .60/.48

the cold side a/r really doesnt matter at all just another spec.

the trim is what u want off the cold side.

now is the hot side .60 or .48? if its 60 go for it itll work.

Re:Turbo Help Please
 

Here are the specs
Brand: Turbonetics / Garrett
Model: T3/T04B (.48/.60)
Size: T3/T4
Compressor A/R: 0.60
Compressor trim: 50mm
Turbine A/R: 0.48
Turbine trim: 45mm

Mabie can you explain what that means. What is the trim?

Thanks
Larry
