After posting a few pics, it's been five weeks since we've heard anything from the OP. What's the latest on this swap? Or is it dead in the water?

I spent the last year researching and finally accomplishing a similar swap (HR into a G35 coupe), so I felt like bringing this thread back from the dead since I kept stumbling on it while doing searches for it. As a background, I went with the HR because something of a loophole allows me to use that motor in my G35 coupe, which is running in SCCA's ESP class. Due to the class rules, I'm limited to what's available on the G35 (07-08) with limited allowances to modify components for the swap, and was able to get it up and running within the confines of the rules.
Some notes:
- No CEL.
- VDC and ABS work fine.
- HR ECU talks to the DE body and dash through CAN. As a side note: you can load a 350z HR base map onto a G35 HR ECU (which I needed to do since the 07 G35 sedan apparently has a different protocol than the DE Z/G).
- HR starter cleared the DE steering rack. It's close but no issues with it so far. May have to play with things when replacing the starter later but I can live with that since it's not in a terrible spot to access, even with long tube headers.
- DE radiator works with the HR. I used the lower hose from the HR and the upper HR hose didn't quite reach, but the DE lower hose can be cut to work as the HR upper hose.
- Steering controls are activating the UpRev map toggle, but I can't get cruise to "SET". I need to go back over the ASCD wiring.
- Initially had the dreaded "high idle" common on HRs when people clean TBs, but with Nissan Datascan (III) have been getting the Idle Air Volume Learn to stick (fingers crossed).
Car runs and drives great. It's a little odd at first watching the RPMs max out on the tach, but where the DE used to run out of breath the HR keeps pulling.

sooo, bare with me for repeating questions or asking silly ones but yes I'm currently swapping an 04 de to an 08 hr (I picked up cheap), since the Nissan mag write up is officially gone and I can't find anymore) I wanted to know if running a haltech platinum with the de ecu (to not have to swap entire body harness) would work ?

okay so I've got everything wired in, engine started like a champ on the test drive, dash light up too, but I'm not getting RPMS or mph still... I kept the Fues box from the de engine, if I get the hr, could that be the issue? also I'm having trouble finding where to plug in the bigger size plug from the wire harness, by the passenger side foot area.. any ideas? thats all I have left to have my old girl running perfect again!
