I'm new here and completely new to Porsche and I was looking around at turbo kits for the 2.5 and none of them offer upgraded internals.
My question is this; are there any manufacturers that offer things such as lower compression pistons, rods, crank, etc. for the 2.5's?
I was looking into fabricating my own twin turbo kit for a 986 but I can't machine pistons and there's no way I could run more than 6psi on the stock compression (my target is 16 to 20 psi)
Thanks for any help.
