Hey guys Top Secret has achieved 690hp with this. I don't know what is, I only know they have changed the vq35 by the vq30. So if anyone knows what is, please tell me.
And, why the change of the vq35?? The vq35 has more capacity, Won't be better the vq35??

Thanks

vq30 is out of the gloria a jdm nissan car. they swapped the motor into the z, the gloria comes with a turbo from the factory so its much easy and cheaper to mod an engine like that. obviously it was completely built to get those kind of numbers.

that's a built VQ30DET from the Nissan Cedric/Gloria, with a single turbo.

The shiny piece on top is a custom intake manifold from Top Secret. I doubt it would fit on the VQ35DE, but even if it did, you would still have the problem of the relocated throttle body. It won't work well with the engine bay arrangement in the 350Z.

Anyone know how much it would cost a VQ30DET engine? (or where do they sell them)?

1986 300 ZX turbo has a VQ30 turbo motor too......not exactly the height of engineering mind you

just the engine alone is $3000.00

That price is in AUD$ so about US$2100. You'll need more than just an engine though. Sensors if not a full loom, ECU and any adapters or modifications to fit it if it doesn't directly bolt in to the chassis and trans.

Z1, I think the old Z had a VG30ET (single OHC) not a VQ. They are a totally different series, not the same thing.

Money-wise you'd be better off getting a regular VQ30DE from 95-99 maxima. The VQ30DET only has a different intake manifold and I believe 9:1 pistons.

azrael

no. money-wise, you'd be better off building the VQ35DE that you already have sitting in your car.. by a long shot.

Why would you want to build a VQ30 from a maxima when you can build a VQ35?

Can someone clear up where the info came from that this is NOT a VQ35 (please don't say Super Street) I have seen pics of the VQ30 that Top Secret put in a Z32 and R34, stroked and bored to 3.4L, but the motor in that pic is a VQ35. Maybe not in displacement anymore, but the front cover, cam covers, even the CVTC solenoids are all VQ35. The two cam gear housings on the front cover are VQ35 specific. The VQ30 has an almost flush front cover, and different cam covers to fit the different heads. The two are not interchangeable. Even the last VQ30DE-K had VTC but the cam gear housings and front cover are different. The Gloria's block will not accept the VQ35 heads, front cover, or cam gears. Even if the crank was swapped from the VQ30, then it would only be 3.2L. The VQ35 crank in a VQ30 would be 3.3L and an almost perfectly squared set-up. In any case, I just find it hard to believe that is not the VQ35 block, too many discrepancies.

thanks for this post. I've actually been wondering that myself for a long time. Most people don't notice these details.. my Mom's last car was a 2000 Maxima with a VQ30DE-K, and it looked nothing like the motor in the Top Secret car. That motor, in contrast, looks virtually identical to the Z's VQ35DE without an engine cover. Good points.. I wouldn't doubt it Super Street got the story completely wrong, but who knows.

The Nissan JGTC GT500 Also using VQ30DETT Engine instead of VQ35DE.

gabe - I stand corrected

sausage5000

it's always cheaper to buy a complete JDM boosted engine than working custom from scratch. the problem is how difficult is it to make the new engine fit. too bad it's not like teh 240... you just slap that JDM badboy in for almost nothing.

Acctualy the motor in the pic is a vq30det out of a nissan gloria

Yes, the VG30E(T)s with the single turbos could make huge torque but run into problems making the big horsepower. People would put down close to 600lb ft with only 350 horses. The VG30DE(TT)s had DOHC and were in the later generation 300ZXs.

Your retarted, the first VQ engine was used in the US 1995 Maxima.
