Also one other random question, in theory if someone were to supercharged the LR4 using the N/A heads, valves, and pistons what would be the outcome? Would you be able to still use the stock fuel mapping and ecu from the RRS Sc and would it make a difference in power? Would it work at all? Would reliability and fear of spinning a rod be an issue? Just wondering.

Depends on what components were different between SC and non-SC versions of the engine. If the SC version has all the same bottom end, it might be doable. If a bunch of parts or castings were upgraded, then it would probably be a bad idea to add the supercharger to the non-SC engine...

Me too!! Lol! No, the engine is still sitting at the machine shop. And now the machinist is at a classic car tour for the next couple of weeks. He promises it’ll be finished before I move back to Memphis on July 2nd. Fingers crossed!

The compression ration for the NA engine is much higher, so when you start putting boost to it you run the risk of pre-detonation even with the SC computer. The blocks are different because the SC engine has oil squirrels under the pistons to keep them a little cooler. I imagine if you tried to make the swap you’d run into a lot of issues with parts failing prematurely because they were designed for the extra stress/heat.

….but then again, any thing is possible!

I do love autocorrect sometimes. We knew what you typed.
That’s what happens when I just type…and don’t proof read….

While oil squirrels I’m under the pistons seems like a better description, oil squirters is what’s actually there! :cool:
