Comparison Of Vq25det And Vq30det Turbos

[zei20l]

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.

looks like its got a T3 flange on the exhaust housing and a T2X dump.

the comp inlet also T2X!

weird as hell!
