What is the best aftermarket piston company, or what should I look for in an aftermarket performance piston? Specifically, I'm looking for 0.020" oversize pistons for my d16a6.

 

Depends upon how you want to put the build together. There is no best out there. There's best for your cheap budget, or best for the compression ratio you're looking for, and even best for putting together something using OEM rods. But there is no best overall. The more specific that you are trying to put this together, the more specific people will be willing to help. And for pete's sake giving a dream 1/4 mile time is not giving information.

 

The word best is thrown around a lot these days lol. The more appropriate word is what is proven.

For example Bisimoto spec forged pistons have been proven on all of our project cars, race cars and many customers cars. Of course we can get any compression and bore sizes.
