i was originally doing a ls vtec setup, so i have itr pistons in my ls hatch. I was wondering if it would be that bad if i left them in there and added a turbo? please give me some options what u guys think would be best

 

i wouldnt use them... there excellent pistons for an NA setup but type r pistons raise ur compression ratio.. and thats bad when ur target is boost. with boost u want low compression and the ls pistons r great low compression pistons.. a stock ls motor has a 9.2:1 compression ratio and thats excellent for boost.
