Ok I am doing a swap on a 06 g35 6mt. It obviousy has the vq35de motor , but as most knoe and I recently learned there r 2 versions of this motor. This car being a n 06 manual 6 speed g35 it has the rev up motor wih vvt or what ever its called. Anyway the motor is blown and I have a non revup to put init.

Almost 100% its motor out of an 03 but ill confirm this shortly. It was out of a 350z manual. Motor is pretty complete. Has exhaust manifolds wih the o2 sensors, intake mani, all thesensors still plugged inand has harness. No computer, no pwr steering pump, no alt. No ac comp. No belts. No starter. Not reusable mounts

The plan:
Swap in this non revup motor, put on the missing accessory drives, plug into 06 stock computer, have reflashed.

Quesions:
Ok I read that the o2 sensors are different, that the 03 motor doesnt have wide band sensors.Is this true?

Will the 03 harness plug and play with 06 g35 computer?

Can the dealer reflash the ecu to make the car flawlessly with non revup motor?

Is there anything I over looked?

correction the g35 is an 05 NOT 06 not sure if thay makes a diff.

 

Ok so after looking he non revup motor believed to be from an 03 it has 3 wire o2 sensors. Most wide bands are 4 and basic or narrow band 02s are 3 wire.

Is there markings on the motor so I can find out what year it is

 

The easiest way to compare a standard and Revup VQ35DE is the front engine cover:

Standard



REVUP


Also, no I don't think you can just swap in a non-revup engine into a car with a revup harness/ECU, even with Osiris, becuase of the heads and wiring differences...you could take the heads off you blown revup and put it on the non revup, that should work...

 

Cams, timing cover and drill out the heads to convert it to rev up

 

Yeah I understand the harness is diff. But I planned to run the non revup harness as its till hooked up on the motor

 

Yes we explored thie option but would just like to run the stock non revup motor in this car. Its a DD carnothing crazy. Just want the stock vq motor to run in the car flawlessly

 

Correction the g35 is an 05

 

Have motor in car and have the 03 harness still on the 03 motor. Plugged it into computer but car does not start and when battery is hooked up the running lights stay on. Car cranks but no fuel.

 

Is your pump good/priming?

 

Sounds like it never turned on. And there is no pressure. About 2 weeksago I started up the car withthe blown motor in it and it ran.... ran like **** butit ran. Since the swap now fuel.

 

Trying to decide if its because I left t he stock revup computer in the car.... should I get a computer for a nonrev up

 

Hey bro, I'm having to make the same choice you did. My '06 Z M/T has a bad rod knock and needs an engine. I came across a '04 g35 M/T and was wondering the same thing. How did it work out for you?

Any input would be greatly appreciated bro.

Thanks
