No prob. At least I think the VK is used in the newer cars. I remember seeing an issue of Popular Mechanics where the two engines were compared side by side. You could also view it from the standpoint of Nissan still having to make two different V8 blocks. Not very practical, even if one version was in relatively small numbers.

I think there were also an advert or two about the racing and production blocks being the same. That was a long time ago, and it didn't appear very often, though. Nissan/Infiniti needs to work on better marketing for their products, especially for Infiniti. There are hardly any commercials, and they are seldom shown.

Re: Vq30dett Vs Rb26dett

I thought the current Q45's were using the ol' VH?

Nope.

1st Gen 1991-1996?? Q45 had the VH45DE
2nd Gen 1997-2001 Q45 had the VH41DE
3rd Gen 2002-up Q45 has the VK45DE

Re: Vq30dett Vs Rb26dett

It stil to early to decide what nissan will do. Who knows what the new GT-R wil use, a 3.0 V6 Turbo, a 4.5 V8, 4.5 V8 turbo, its just too early to tell.

Its never too early to tell. Just have to know where to find the right information.

Re: Vq30dett Vs Rb26dett

Im guessing nissan will use a turbo v6. Maybe even twin turbos.

Re: Re: Vq30dett Vs Rb26dett

Do you think nissan will ever use a single turbo on a Vq or any other model engine thats high performance.

They've had single turbo VQs for a while now. The VQ25DET is rated at '276hp' and is used in the Stagea, I think. Maybe some other vehicles, I just don't know. The VQ30DET is rated at the same '276hp'( riiiight ) and was used in the Cedric/Gloria twins(JDM 2002-2004 Infiniti M45).

I also think there were VG30DET's as well, before the VQs came around. There could be a QR25DET 4cyl in the future, as a couple new concepts('Azeal' and 'Sport Concept') have hinted at being turbocharged.

Re: Re: Re: Re: Vq30dett Vs Rb26dett

?#2 This about the Z tune very basic question. What is the topspeed because all the mag's are saying its the fastest production car ever. But if you ask me its a tuner after all nismo is nissan motorsports. Its basically saying the hennessey viper (1000TT) could be called the fastest.

#3 what work does the Z tune actaully have done to it and is it a basic Rb26dett under the hood?

No idea on the Z-Tune cars, whether it be the Z33 Fairlady Z or the R34 GT-R. I haven't seen performance tests for either of them.

The Z-Tune R34 GT-R had a host of revisions, including a full restoration(similar to Nissan USA's 'Z Store' campaign), and lots of NISMO parts. Since there were only 20 made, NISMO probably went all out to make it a collector's item. The interior, exterior and suspension probably benefited as well. The RB was stroked to 2.8L, and produces around 500hp.

Is it tuned the same as AF's R34 race car? Id think it has the same layout anyway...

Re: Vq30dett Vs Rb26dett

There's a big think that NISSAN might go vq30dett for the new r35... but in my opinion they could stick the vq25vet because is light as hell (that engine is only 10~lbs more than the qr25de) and implement the VVT / CVT for eng & tranny combo. BUT ALL U GUYS ARE NOT WATCHING OUT For Honda... cause their S2000 (bad ass Vtec) could or have inline 6 ....Damm all Hell is goin' to brake loose!!.

The AF R34 is 500 hp. On paper the Z-Tune should make more power than 500. Its a 2.8. Its got bigger cams, its got larger turbos.

The GTR will most likely use a N/A 4.5l v8 like the Q and M are using. Factory turbocharged gasoline engines are going away for the most part, at least in the states and Japan. I've read up as much as I could find on the next GTR, and all the writers who sounded like they actually knew what they were talking about agreed that the 4.5l 8 will be what Nissan chooses. They're just cheaper to build and warranty than the twin turbo 6's are.
