this will be a street driven car. will be going into a gsr motor. looking to make around 450hp

9:1 dish.

:Josh:

2nd that

Use 8:1 & below if you have a large-displacement motor and/or crappy tuning, and 10:1 & above if you're running NA or mild boost. 9:1 is going to give you the least problems, and you won't be missing out on very much power at all. Its just a handful of off-boost ponies, after that you just use an increase in timing & boost to more than compensate. Everyone wants to run >10:1 because its JDM, and what's-his-name made XXXwhp with 12.5:1 on boost.

eg:R

will be on a 2.0liter

My vote is 9:1 CP Pistons

eg:R

i wont be getting cp pistons, because i have chip cp piston twice in a month.

i wouldnt blame the piston.

Yeah, I would not blame the pistons, you must have valve to piston clearences wrong, or something else going on. I have never heard of CP pistons just chipping. I would say they're one of the best on the market.

buy the lowest comp possible... looks like what u have is a syndrome of "no tuner or **** tune" going on.

Especially on a 2.0L (84mm bore I assume).

eg:R

it was on 81mm pistons, i got it retune after it happen and still same thing.

Chris Tune

you should be making close to 800 then i have done quite some 450 whp engines and the ones i have disassembled for upgrades the pistons look like new. kinda strange...

JDogg

if its a pump gas street car get the lowest you can, we always use the -18cc wiseco pistons, they will get you a hair under 9:1 depending on the setup.

and yeah, cp pistons suck. the last motor i saw with cp pistons fell apart b/c the piston broke in 1/2 over the pin

twkdCD595

oh here we go with the pistons agian. cp pistons are hardly shitty... some people have also had problems with wiseco's too and je and arias, etc... its not a perfect world. alot of people are making huge power on cp's and having no problems... same with wiseco and others. can we not make it a pissing match for once.

back on topic... 9:1 dish would be what I would run, just my 2 cents.

Max500

9.0 : 1 dish I recommend as well for that power level.

eg:R

thanks for all the replay guys, will be getting some 84mm arias 9:1 dish
