Hello, im new to the g35 scene. i picked up a 2005 G35 coupe 6 speed over the weekend with a rodnock that i am going to swap the engine on. I did find a engine that came off of a same year and model RWD g35 but sedan automatic. now is the engine direct swap or the wiring also need to be swapped out? and anything else to replace while at it?

 

The car you bought came with a revup engine, more hp, whereas the engine you bought is a different engine all together

 

Why does it matter is it's the same year?

 

No. It won't be a direct swap.

Different sensors, different engine cals-- at the least.

 

The revup engine also has exhaust valve timing I believe, which the sedan did not. Sorry, but you are stuck trying to find 05-07 6MT Coupe engines.

 

type this in your google search bar ---> rev-up vs non-rev vq35de
happy reading!

I assumed you inherited this car for free since it has rod-knock?

 

So in 2005 only 6 speed manual coupes had the revup engine?
Also I picked it up for 2500 with ksport coilovers and varrstoen 19" wheels.

 

05-06 6MT Sedan is a revup and would be fine as well which has the exhaust valve timing.

 

no. The 6 speed 05-06 sedans have the revup as well.

 

i literally just asked this kind of question like 2 weeks ago and i got no help lol but i figured i share my knowledge with you from what i learned from a bunch of forum searches. but anywho ..

mine was a bit different. my car is a 04 coupe 6mt and i got an 04 sedan automatic engine. mine for sure was a non rev up. if you dont know the diffrence looke behind the head toward the firewall and look at the cam position sensor. non rev up have 1 on each side and rev ups have 2 on each side (total of 4 on both heads) now that thats out the way you will need to change out somethings. fuel rail with injectors from your old motor. also you are going to want to switch your knock sensor located under the complete manifold. be super careful removal. That stupid sensor is super brittle. both of mine broke into peices and i had to hard wire and tape the crap out of it so heads up. after that just make sure your o2 sensors match up and everything else is plug and play. theres a bunch of sensors behind the motor so make sure u get all of them b4 you start to crank the engine.

GOOD LUCK let me know if you have any questions

 

also the original flywheel on the automatic engine leave behind this like adapter plate. MAN that this is annoying to get out. only way i was able to get it out is to weld a nut around the hole small enough to fit a nice long bolt into and impact the bolt str8 out. if the weld breaks keep on trying untill that adapter comes out cause you wont be able to fit your new pilot bearing on

 

So those are the only things that need to be swapped out? Also you said rev has 4 camshaft position sensors while non rev has 2....how do I swap those?

 

Has a 10mm bolt holding them in I unbolted them off my heads and left them on the harness it was kind of a pita to remove the clip off the back for some odd reason but if you don't want to take them out just un clip them and that's it

 

And yes those are the only things needed to swap out as long as your motors are identical.

 

Hey man can you email me or text me so I can ask couple more questions? Your help will be very helpful to me
