Alright my friend has a t4/t04e 57 trim 58 a/r that he cant seem to get rid of. I'm planning on doing an ls swap into my rex in the near future, and I was wondering if this turbo is too big for a stock ls, and if not what would the spool time be like.
Thanks in advance

 

it should be fine for you

 

here's a couple pics of it for reference

 

that flange looks bigger then a t3/t4 looks like a straight T4 either way will go fine with your ls

 

that does look like a T4 flange. it will have some lag with your ls. just so you know that.

 

i know its gonna have lag, im just trying to find out how much. would it have any more lag than an sc61?

 

I would say a bit more lag. my gt35r dual ball bearing has full boost at 5000 rpm on a built b18c1.

 

hmm mabye thats not such a good idea then, i wont be at full boost till redline

 

looks like my new turbo! I'd say for a stock ls you should have 10+psi by 4500-4800 rpm.

 

how much power does the straight t4 t04e 57trim w/a .58exh support? anybody know the cfm? thanks
