I'm a a noob with turbos. I've had bunch of na cars including 220whp b20vtec eg. Now the question, my friend has this turbo kit. Its a garrett t3,t4 with air .60 and 63 hotside. 4 bolt Can anyone tell me whats the trim size is from the pics and how much whp can i get out of this turbo. I got a darton sleeved b16 block with je pistons and eagle rods, type r cams and ported b16 head on the intake side.
Here are some pics.
Im hopping to make 350-450whp and wondering if this is the right turbo or should i get a different turbo. sorry its pretty noob question. first turbo project.
how can i tell what is the trim size and if you have similar setup with this tubo please post.

 

gonna need inducer/exducer measurements also.

 

it can be either a 50, 57 or 60 trim. those are the most common and most popular. they can all do 400hp with the right tuning.

if you want to find out for sure which one it is you would have to measure the wheels.

 

Do you know the measurements for each trim size. Ill try to get those today and post them.

I was gonna get a gt30 turbo, but since this is my first turbo project i'm gonna keep it t3/t4. Pluse this will be my daily car/ race 1/8th mile track.
What size injectors do i need for 375whp to 450whp.

 

880cc injectors

and it looks like a 60trim compressor

good for a out 350whp - 400whp

shows how to measure and calculate trim. it cant "look like a 60 trim compressor"
the a/r is .60, thats covered in section 2 of the link

 

anyone runing this turbo on their cars. I would like to know spool time and hp numbers.

 

I measured the wheel and it was 2.5 inches on the turbo a/r side.

 

did you click the link i posted above?? you arent measuring the turbine discharge, you have to remove the housings and measure as shown in the picture then do the math. you are more interested in the trim of the compressor

regardless, its capable of 400whp and should be at full boost before vtec. it will vary on each setup and the complimenting components. if you dont feel like taking it apart then just run it as is, very popular turbo for a b-series

 

yah im just gonna use it then. I'm just gonna hope ill make 400whp at around 20psi or so. THanks for the link though.
