VQ30DETT

[EfiniRX7]

I am curious on how much a motor like the VQ30DETT from the GT500 Skylines in JGTC is worth? I am just curious I guess.

[irax]

if it is really from a GT500 skyline.... then its probably a 3.2 and puting out a good 500hp..... and... you know... worth 30-60k

but... a VQ30DET-T from a gloria... well thats probably a good 900 bucks...

[EfiniRX7]

I have a VQ30DETT. There is a sopt on the valve cover that says VQ30DETT seriel 001 in those words. I know it is all aluminum because I can lift it with another persons help. The motor is assembled as well. I will get some pics up soon. When I was reserching this motor I found that it was never a production engine but only used in the GT500 cars from 2003-2006. I know the vq30det was in the glorias, but this engine is marked as vq30dett. The engine also has the signs of a race motor like the dry-sump. The person that I got the engine from has had it for a long time, and is in some kind of position with Nissan. I know pictures will tell all. I will get some up tonight. O and the guy I got the engine from knows it had some kind of racing history. But I do know it is a VQ30DETT it says it right on the valve cover.

Let's see some pics!!

the jgtc engines were 3.2's like irax said, so im not quite sure what youve got on your hands

i cant think of any other cars that would use anything close to the jgtc engines either, the prototypes from the late 90s all had small displacement v8's, the nissan engined prototypes here ran alms gt2 with turbo 4's, super taikyu runs engines developed from vq35s and sr20s, etc etc...not sure

[EfiniRX7]

Is it possible the gt500 cars are a stroked vq30? Im working on pics sorry for the delay. I will have pics up tomorrow.

[nismofly]

i was actually trying to look that up thinking about this, i dont know the bore/stroke of the vq30 or 35 off the top of my head, they could be destroked 35s, or they could be bored and/or stroked 30s, and the latter might explain the name

but all specs ive seen about the car have always called the engine a vq32dett, and you cant look up anything current because theyve been running the vk's, and the new gt-r is going to retain that engine, so any info you find on vq powered gt500 cars will be from archives

[EfiniRX7]

I know wikipedia is not always right, but if you look up vq30dett on wikipedia it says this, The twin-turbo VQ30DETT is an engine used in Nissan's race cars, primarily in the Super GT (formerly the JGTC). First used on the Skyline GT-R race cars during the 2003 season, this engine currently powers the Fairlady Z race cars - homologation rules allow them to use the VQ30DETT in lieu of the stock VQ35DE. Race output of this engine is estimated at around 480 PS (473 hp/353 kW).

It is fitted to the following vehicles:2003–present Skyline GT-R JGTC race cars2004–present Fairlady Z JGTC race cars2005–present Fairlady Z Super GT race cars2006–present Fairlady Z Super GT race cars

see thats wrong immediately because the super gt cars now use the vk45

ill see if i can find super gt or nismo archives talking about the old car specs to prove it, but i know they were 3.2's

[EfiniRX7]

^ I dont think your wrong, Im just posting what info I found.

[Dracolove]

Just because it is wrong about the super gt cars doesnt automatically make everything else wrongand if it was a 3.2l then more then likely would have said VQ32DETT

[nismofly]

thats what i was thinking

but the only other place i can think of a vq30dett would be drag racing, because no other nissan engined racecar runs a twin turbo VQ, anywhere

but i dont know enough about drag racing to tell you if thats where it came from

If it was a 3.2L it would have been a VQ32DETT. Why do you guys think it was 3.2L?

[VQ30DET S13]

The simplest way to make a VQ32 is to use VQ30 crank and rods with VQ35 pistons and block. Basically a de-stroked VQ35.

If they were to stroke a VQ30, they would probably use VQ35 crank and rods with VQ30 pistons and block, but that would produce a 3.3L engine....

ya know what...it is a 3.0

i couldve SWORN i saw 3.2 in an article i read, but believe it or not i found the article, and not only is that displacement right, but i can tell you that its got a 93.0mm bore, and a 73.3mm stroke, making 485 ps and 520 trq

sorry about the wild goose chase efini, i think i may have been thinking the gt500 NSX when i thought 3.2 instead of 3.0

now i feel stupid

Everyone messes up sometime. I guess I do have a gt500 skyline engine on my hands.

so where are the pics??

i would love to see that engine

I will try to get some tonight. I know I have allready said that, but I have ben preocupied with adjusting my new coilovers and wheels.

[nismofly]

forget pictures, find an engine dyno somewhere, see what it sounds like haha

also if its serial 001 that sounds like something significant

[EfiniRX7]

Dang once again another night tunning(making it driveable) the new suspension. I am officially finished making my care driveable again, so now I can snap some shots to give you all a better idea of what this engine could be.

[EfiniRX7]

Here are pics.

[nismofly]

infiniti?

[EfiniRX7]

^ I know sort of strange.

[VQ30DET S13]

Bummer, I was hoping that it was one of these...

That looks like a 4th gen Maxima VQ30DE. My VQ30DET has different valve covers...

[VQ30DET S13]

Looks like it's from an Infititi I30.....

How do you explain the DETT part. All the reserch I have done has told me that this engine has never ben in street car production.

It looks like a non-factory made sticker. It was probably just confused with VG30DETT...

[EfiniRX7]

^ No when you actully look at the engine in real life the sticker looks like it has ben there since the factory. In the other pics you can see VQ stamped in the block.
