Building up a single overhead d15b2 into the mpfi conversion and want an all motor build- can anyone tell me what the best recommended bore is and what piston company is best rated for naturally aspirated builds?

 

What you'd spend trying to Bore this thing to B-Series displacement, could be used to just...cop a B-Series.

 

i was thinking more like boring it to a 1.6 single which i believe i found was a 50 bore and it would have excellent acceleration on a low compression build with turbo or even better on a high compression build with top end build and crank, cam, etc.... i guess my main issue is whats the best company to use for pistons on either build?
