i have an N/A ls/vtec with 11.1 CR pistons. i was looking to go FI soon and was wondering if using a thicker headgasket to lower the CR a good or bad idea. the thing is, i have about 3k miles on the new Srp pistons and would hate to spend the money to get new ones.

 

the headgasket would help... what sort of boost/power levels do you plan on running? the srp's arent good for higher boost levels because of the silcone content (at least thats what i remember)

 

thicker headgaskets i find are not worth the money and trouble of installing

 

you need lower compression pistons.

 

thick headgaskets will help the engine live at high boost levels, but will NOT help make any power... too much piston-head clearance is bad
