Does anyone know if you take the two and put them together will it work out? Id like to try this because the HR heads have the (NDI) Nissan Direct Inject. which injects the fuel right into the combustion chamber, allowing a computer to precisely meter the correct amount to use, rather than into the intake tract. this would improve mpg while also getting better power. anyone heard or thought of doing it??
on a sidenote, has anyone tired to drop a full HR motor in our cars? I know that the HR motors are only in RWD. but you gotta think nissan didnt change the bottle pattern from the DE to HR did they?

As far as I know, Nissan hasn't used direct injection in the VQ35 as yet. There is an article floating around that Nissan is finally ready to use it in the upcoming Infiniti M37 and in the G37.
No. The HR did not have DI. Yes, the head will bolt-on but you will have to use the 4th gen intake manifold.
doesn't the DE motors only have variable timing on the intake cam and the HR motors have variable timing on both cams , if so he'll probably need the ECU and harness .

i believe : the HR won't fit , the mounting holes/points are different from RWD to FWD . you would probably have to change the intake manifold on the HR , one of the throttle bodies might be right up against the firewall , just thinking
fwd and rwd blocks have different mounting point. yes the hr has it on both sides. you would need a cap to use to fill one hole near the cams. this is how the z guys put revup motors in there de chassis. they dont gain anything from this swap.
this thread is teh fail!

Yup. But that's an easy fix as TUKO mentions below.

It's only a FAIL because he wont do it. Now the HR head swap would actually be pretty cocol with the bigger intake/exhaust ports, more aggressive cams. It would definitely pep up the 'DE.

well down the road when i get another car, hopefully ill be able to keep this one and build the whole car...which i would want to put a HR motor in the car. lol

spending that kind of money , why not just turbo it instead

why? why not just build the motor thats in the car? the hr motor benefits from the cvtc on both intake and exhaust. when swapped into your car you have to eliminate it on one side. you get a slight increase from the cams but with that money spent you can pick up a set of brian crower cams for 850 and have more power.

you have a lot to learn.
^^^ i agree .
unless the OP can get free parts and owns a shop to do the work in , it a waste of time and money . there are better ways to make power with the same money he would be spending to make this work .
