i want to know what size turbo i can put on my stock ls. with out having that much turbo lag. my goal is to at least reach 300hp.

 

tried and true t3-t4
there are so many options but if you are looking for 300 whp, you really dont need to go into the gt spec stuff. this is just my oppinion. please add if i fucked up or missed anything.

but if you want to go baller, GT 28R should put you where you want to be also.

 

Ah. you can get some GT series without paying the larger bucks. There are are some in the GT series that are not ball-bearing, but still use a GT wheels (one of my "BLUE PILLS". I've made several of those for the LS without any issues. Give me a shout.
