Good, and yourself? Still working on my never ending project (the G)
The 4.2L HR stroker is non-sleeved while the 4.5L HR stroker is sleeved. This customer opted for the 4.2L (higher redline) we have a 4.5L in the works for our G37, but that's on the back burner as customers cars always come first - we don't always get time to build up our shop cars as quick as we would like

Hey George, do you guys ever take a break?
so sticking to the thread title, whats needed to do a HR swap into a DE platform? Custom motor mounts, HR ECU, HR engine wire harness, HR long block w/all accessories???? what else am i missing?
Very interested in doing the swap in my ride.

I understand the HR engine was designed to sit 15mm lower in the engine bay than the previous DE [supposedly for a lower center of gravity], but im wondering if this would cause any fitment issues with the hood or steering shaft, or alignment issues with the transmission.
Same here. Curious to see the results.
Probably didn't get much response from here compared to my350z.
Driver is more about flush wheels and body kits. LOL! Just kidding!
