Default Question for the real gearheads

These are getting installed i my OBD1 GSR

ITR intake and exhaust cams
Skunk2 mani
Skunk2 cam gears
ITR intake and exhast valve springs
USDM ITR pistons
Crower ti retainers
b16 TB bored to 66 MM
VAFC
Ported and Polished head
Mugen Head gasket

My question is this, should I go with CTR pistons instead? Will the 12.2 CR be too high for 92 or 94 Octane?

I baselined at 152 HP with AEM intake and Greddy Evo exhaust, how much power do you think the above setup will produce (along with DC 4-2-1 headers)
I plan on selling the 4-2-1 to acquire a JDM DC 4-1 and a carsound cat, I was uneducated when I bought the 4-2-1

CTR pistons in a B18C5 yield 12.25:1 compression, in a B18C1 they'll yield even MORE compression.

12.35:1 is your compression w/ stock gasket and CTR's.

Just do the ITR's and the Mugen gasket. After the head is polished, have the machine shop mill 5 thou or so at the same time of getting the valve job done.

Tell them to go thin on the seats, BTW.

Mike,

What do you mean bu go thin on the valve seats?
I was trying to stay away from milling the head in case I wanted to get some wilder cams later. If I am reading you correctly, you are saying the the CTR pistons will bump the CR too high.
