OK so ive found a turbo from a VQ30DET and i was wondering if it was the same or slightly larger than a VQ25DET turbo from my M35

for the price he is asking, its probably worth having on my shelf incase mine dies in the ass

the one for sale has 4P2 on the compressor housing, along with nissan. he is certain this is from an VQ30DET, but id like to be sure before i buy it.

can someone please look at FAST and tell me if they have the same part numbers? or any information regarding these turbos?

vq30det.com didnt have much on the specs of the turbo.

thanks guys!

From what I have heard so far it is unlikely that it is a straight fit as the M35 is described as having quite a unique turbo.

Give me a call and if you want to drop around this evening or i can organise to give you the FAST disc tonight.

Cheers

ahh yes the FAST disc! hmm tonight. ill PM you andy!

the turbos MAY be the same. if the block design etc is the same for all VQ engines (only bore and stoke may be different) then i rekon they might be similar in design and size (the turbos i mean)

Although the turbo might look similar they are actually far from identical. neither of the housings are the same so you wont be able to bolt any of the compressor side factory cast fittings to it. Even the exhaust housing is different.

Ive been down this path and its not worth the hassle.

Ive got some good pictures of the vq25 turbo if you want to compare things.

      r34's love to squeal

      By Nizzy_R34 · Posted

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
