Im going to be geting 82mm Wiseco pistons with eagle rods to run in my B18C1 with t3/t04e turbo. What compression ratio is good for this setup runing around 8 to 15 psi. Thank you.

 

are you going to up the boost later in life? just run 9.5:1 and you can have some fun.

 

my setup is almost the exact same, only my wiesco's are at 81.5mm, i went with 9.1 cr. you'll be fine with 8.75-9.5. there are advantages, and disadvantages to all Cr's, what is the car/motors goals?

 

its going to be a dailly driven car with some 1/4 mile track times. Looking to get around 350hp to the wheels with Uberdata. I dont want to run too much boost with it. Just want an overall fast street car.
The reason im going .40 over is that i cant find any .30 over pistonsand i dont want to get into custom pistons.

 

call payne tech in detroit. i'd say @9.0:1, w/12psi you should be happy. try looking at the t3/to4e 57 trim compressor map. it might work out well for you, cheap too.
