I currently have a 01 TA LS1 with a 150 wet shot. What would you reccommend i upgrade to that has a at least 550rwhp on motor and that will handle a 150-250 shot.
I would like to keep the LS formatt if possible.

Also who makes a good pre-built motor assembly???

 

Check Katech if you really wanna shell out some cash, they're the ****, honestly. Also many of the sponsors can get you in that direction.---->
