cupcake17225 Posted January 29, 2008 Posted January 29, 2008 i no a good bit about cars and fixing them but when it comes to swaps and how stuff will do on it i get easily confused. i have a 93 sdn with a swap to a b16 and the gsr high compression piston and now the # 1 cylinder now has 50 psi while the other 3 r still pushin 225 so i no i need pistons but i plan on turboing very soon and i no i need lower compression pistons and i wanted to no if LS pistons would be good enough and wat would be a good boost level for them.

If your running low boost then factory pistons will be fine but buy forged.
Hatch92 Posted January 29, 2008 Posted January 29, 2008 if you plan on boosting it you may want to find out if the piston is bad now or if the head might have something wrong with it.
