I have a 06 sedan mt rev up engine that’s blown beyond repair so decided to swap to de I have a engine that’s out of a automatic 02-05 g35 area not sure what year I’m about to start rebuilding so my question is what do I need for the swap I have original harness and ecu atm to the rev up engine

 

Do a google search for "g35 rev up to normal / regular de swap" there's a few threads out there.

Personally I'd just use the donor short block and swap over the heads from the rev-up. Rebuild them if needed, new head bolts, new timing chain, gaskets, rev-up oil pump, reuse the rev up oil pan baffle.

Then you don't have to screw around with all the other stuff and you keep the rev-up engine. The only difference between the regular DE and the rev-up is the oil pump, heads assembly, oil pan baffle. Technically the connecting rods are "different" in that the rev-up ones can handle about 20 extra whp before bending, unless you're boosted this isn't an issue.

 

Thank you for the information will be helpful for me sounds easier then the swap itself lol so will probably go that route to avoid headaches
