R390 GT1

Post by **SSDwellah** » Tue Oct 24, 2006 9:23 am

I searched but I did not see any topics in this forum about the R390. Does anyone know how related the VH45DE and VRH35L are? I guess the L version was a LeMan's version. There was an N/A street version sold in the rare R390 production car. I wonder if the crank will fit a VH45DE block. I bet the engines are very closely related but it would be cool to find someone who makes/sells some of these race peripherals (turbo setup, IM, valvetrain, rotating assembly, etc...)

Yeh the R390 GT1 road car has always been one of my dream cars... pity there's so little verifiable information out there about them !

I'd love to see one of those motors out of the car & being rebuilt ! 180 degree crank... mmmm!

I know that the R390 engine was based on the earlier R89 and R92CP engines. These were called the VRH35Z and came out around the same time as the VH45DE was released. I am convinced that the pedigree is a lot closer than some people would tend to believe.

For those of you who played Grand Turismo 4, there is a driving test that uses the R89 or R92CP (don't remember offhand) and it is a wild ride approaching 250MPH. If only it had a 6 speed manual instead of just a 5 speed.

A few factoids:

The GT1 is a race only car but the regular R390 was actually sold as a production vehicle in order to meet the entrance requirements.

The red/black open wheel car above is actually an R391 (I think this is N/A)

The headlights used in the R390 are from the 300ZX Z32 possibly because they meet EU regulations, and/or possibly just to fit in with nissan styling (also the Lamborghini Diablo uses the same headlights because of the same problem and covers up the Nissan logo).

The engine research was performed in 1983-1987 and is written up in an SAE whitepaper. (Imagine what Nissan is working on now that you won't see for 10+ years!)

i watched a commentary video on the R390 last nite

the japanese driver mentioned 800 ps for the actual race ... and 1200 ps for the poll lap with tyres designed to last one lap

he also said ... he has never experienced acceleration like that ever since ... not in 30 years of racing ... and doubts schumacher would have felt anything close to the acceleration of the R390

the video showed the car and engine bay etc

Wow... I didn't know Nissan made some V12's.

Post by **SSDwellah** » Tue Dec 26, 2006 10:56 am

Yeah that was the first time I had heard of their V12's as well.

Where did you guys see/read about the Nissan V12? I didnt see any in that Datsun510 link...

Post by **SSDwellah** » Tue Dec 26, 2006 5:27 pm

NP35 Race car, look a few pictures ahead and look closer, that is not an I-6

Post by **Boosted 70z** » Tue Dec 26, 2006 5:53 pm

Nissan built their first v12 in 1968 for the R382, a race car they raced in 69.
