Ok so i dropped in a ls motor into my rex and it smokes alot! im going to change the piston rings bc i did a rebuild w/o changing them i had plans to boost the stock ls but then i was thinking other options here they are :
1. p30 pistons with a b16 tranny
2. p30 pistons and p72 head in the near future
3. replace rings and keep saving for a turbo kit

Any help or opinions would be appreciated.

 

do what is going to make you happy if you want boost wait for it... trust me it will be worth it in the long run... So i say rebuild and boost the SH#T outta it...
