What is the best over size bore? Would like to produce enough hp to run low 12's. How much hp would be needed to run low 12's? What type of piston and rods would be needed?
Bore Over Size???

a larger bore doesn't really make more power on a forced induction engine.
On my current block, I was forced to go 1mm oversize to clean up some deep scratches. Now, if I get scratches again.... time to find a new block. Go the minimum.

go .020 over. and dude...make sure u take it to a respectable machine shop who has plenty experience with supras, or at least with imports. i personally know 3 people here in central ohio, myself included, who have blown up built 7ms (all running low boost and within 1500 miles) because of faulty machine work- mainly miss boring. and these were shops who had YEARS of experience building race car engines (domestic v8s however). seriously...do ur research before taking it in. u don't want to find yourself in the same boat as me right now, lol.
And don't forget to take your cam belt tensioner along and have the shop torque it to 36 ft/lbs while it's being bored...
Great information and thanks. I do know a shop in Illionis called Sound Performance and they deal a lot of supras. They are my first choose when I rebuild my motor. Thanks again.
