So I plan on putting the On3 turbo on my gt and I am trying to get 400hp on it. I was wondering what parts I would need to get or that would be smart to get. I already know that the stock rods and pistons tend to go out around 400-450hp and I plan on buying them but I don't know what sizing would be best and I'm not sure where I should buy them. If anyone has any knowledge about this build I would greatly appreciate your help.

MMR has a forged rotating assembly. That’s what I have. As far as size, are you asking about cylinder bore? That would depend on the condition of your cylinders when you open it up. I could be wrong, but I’m pretty sure you aren’t going to get any noticeable gain by over sizing the bore.
