Hello I have just been stiffed out of a CP piston kit through and online company. I have chosen to purchase all the parts that i can through my local compact sports cat parts place... Summit Racing. I am building a b18b1 turbo block and now am a little confused on what pistons I can trust to hold up to a beating. Summit sells both wiseco and arias pistons. what brand would you use? I know arias pistons come in at 8.8:1 and the wiseco come in at about 9.3:1. would 0.5 differance realy make that much of a diff?

Thanks
Ken
