12 Second N/A Slant 6?

Using KB168 2.2L Turbo pistons on an offset ground crank. +.070" deck on the block.

.055" quench.

You seem to have examined every aspect of this project with a magnifying glass and have a GOOD answer for everything.

It's a well thought out exercise, and impressive in its thoroughness.

Which leads me to wonder how you come to be using "turbo" pistons in a normally-aspirated engine.

I have no knowledge of these pistons, but I think that in all probability, pistons designed for a "forced-induction," OEM application, would likely be forged, and if so, probably might be significantly heavier than pistons designed for no boost.

Maybe that's not true in this case, but it made me wonder.

As you undoubtedly know, normally-aspirated (OEM) engines, usually utilize cast pistons because they don't need the strength of a forging, and I am assuming that these turbo pistons are forged, which may be a mistake on my part.

Maybe you could explain how these came to be the piston of choice in an engine wherein a light-as-feasible reciprocating assembly would seem to be really important.

Thanks for any information!!!

Good luck with your project.
