i was wondering,before i acually complete my ls/vtec build, i am using PCT pistons(JDM),and with the head i will be using i will have sumwhere around 12.3ish:1 compression ratio. i was just wondering if anybody had any suggestion on what fuel i should use, the closes gas stations around me get up to only 93 octane, and i don't think that will halep run my setup good???what can i mix or use to help??? thanks

 

93 can run PCTs on good tuning. If you aren't 100% confident in your tuner then I would use p73-00 pistons.

 

do you know some stuff that is taken into consideration when making that PCT and 93 octane work,or a site where i can look up this stuff??? also does anybody know the diameter of those wrist pins for those pistons???

 

can i use ethanol as a octane booster? and if so how can i find out how much 2 use 2 boost it up 2 my desired octane, i am aware that gasonline has about 15% ethanol???thanks
