There is this turbo that is a turbonetics comp. 0.60 trim AR turbine 0.48. Would this be a decent turbo to use to get up to 250-300hp? tuned of course.

 

is this a t3 or t3/t4? both should make power to about high 200's - 300whp.

 

There's not enough information to make that determination. We need to know where it came from. If possible, wheel measurements would work best. The stamping on the housings are very common and don't help unfortunately.

 

It is a t3 turbo. The turbo is going on a b18c1 with cp 9.1 pistons and eagle rods. It says Garrett on it . How do you measure the wheel?

 

Also Check the FAQs. It is best to measure w/ a caliper in millimeters, please. The housings must be removed to do this.
