M35 - Vq35 Install Using Vq25Det Turbo Setup

[C-Red]

Hey Guys,

My apologies if this has been covered before.

Just wondering if its possible to install the VQ35 into the NM35 and utilise all the VQ25 Turbo manifolds etc?

Many Thanks In Advance,

Jeff

I suspect Scotty will be able to set you straight on this one.

HKS actually use the OEM VQ25det manifolds in their old kit except for the crossover part of the manifold behind the engine so we know they will bolt on.

Everything else is pretty similar so I can't imagine why it wouldn't... except for the loom/ECu side of course

Yup, but HKS also have that weird flange adapter for the the turbo.

But also changing ECU means you have to go RWD manual though? Otherwise wouldn't you have the change the whole driveline?

Manifolds isn't the main issues. Yes, they bolt on, but the engine management side of things would be the biggest head ache.

Also sorting a turbo and wastegate to suit the 3500cc with the confined packaging.

Change ECU and loom to the PNM35 items. I do not know if it has different connectors than the VQ25det for the speedo etc

Then just run a piggyback or get it flashed.

Change all the ecu's and all the looms. Don't like the sounds of that, too much work and headaches, and for what? The VQ25det is the better engine, unless you plan to drop 15k into the VQ35.

Sure, but the question was installing a VQ35 into an NM35 and using all the turboey bits

[scotty nm35]

The turbine housing is way too small, and the manifold studs will need to be swapped around... And the gearbox won't bolt up, and the starter is in the wrong spot...

Then the cams won't work... and the real drama's begin.

Thanks for the replies guys. 2.5 it is.
