Well, like I said, due to new emissions laws in Japan, they cant make I6's like they did before, so what better option do they have? V8?

 

I guess someone's going to have to define successful....The VR-4s are not bad at all, i think they just got some bad press. You can launch those things at like 7000rpms and be making boost in no time...I think they're pretty fast. And V6s are more efficient I think. Otherwise why would Japan be switching from inlines to meet emmissions laws?

 

L6 turbos are probably making alot more smog than newer V8s. Not to mention how much more emission they'll give out after modded.

They can still make 4 cylinder turbos. But that's not enough to be flagship engines.

V6s are cleaner than L6s. That's why it's replacing L6s, not because it's making more power or anything like that.

 

how can I6 not pass emission in japan? Link to proof?
40% of the cars in japan are running 1jz and 2jz
hope you know that the supra wasnt the only car in japan that had the I6 motor..
all i know is that the emission laws are not that strick as they are in california..

 

Why is an I6 less emmisions friendly than a V6? I thought it had to do with the engine components not the cylinder layout?

 

Actually, I've heard that Japanese emissions laws are tougher, but they have much different things they look for when doing emissions. BTW, most articles I've read about the upcoming GT-R talk about why they don't use the RB26, and the emissions issue

 

I think Japanese automakers are leaning towards N/A engines for less emissions, which is definitely valid. It's just that it's sad to see all those fine turbo motors go into history.

It's like when American domestic cars had all those muscle monsters. Today they have the Focus and Malibu.

 

i would go with the supra, just my 2 cents ,,,,,

 

It won't be right for me to say the GTR, but Toyota has a history of screwing up a good thing. Just REMAKE MY CAR AND GIVE ME PARTS PRODUCTION FOR A LIFETIME!

 

There's an article in the latest SuperStreet or Modified Mag (I think) that talks about "crazy" engine swaps. In Japan, they did a VQ35 swap into a Skyline taking out the RB26DETT. They still TT'd the VQ35 and it made some sick gob of power.

I think part of the "problem" with V-6 vs I6 turbos is fitament issues too. When you have the manifold on one side and have more room to work with, things fit better and don't tend to malfunction as often. Then again, Japan has been shoe horning big engines w/turbos into little cars for eons now.

 

LMAO!!!

 

My choice would be the Skylines. R32, R33, R34 Vspec II, Nismo GT-R or R35.

Now don't get me wrong the Supra is a nice car, but since we could always get that car, it's been done to many times over.

 

... just out of curiosity, I know Japan has "the gentlemen's act" where manufacturers cannot build cars more than 280ps. How is a 450 twin turbo V6 even possible in the confines of Japanese emissions? I don't see how 3.5 yielding 450 qualies for LEV. The only way Nissan's going to produce some car like this is that the car has to be "exotic" and w/ a sticker of at least $90,000 where 25% goes to the government. Nissan went under once and the company is controlled by the Dutch (I think).

 

The gentlemen's agreement is just what it says... it's an agreement. I don't think it's a law. It's awkward to produce cars with over 280ps but the'yre not gonna be sued for that.

Or they can just drop off their 450hp VQ35DETT V35 GTRs at Nismo for some cosmetics and tuning. Since it's not from the factory those cars are not under the gentlemen's agreement.

 

Does the gentlemans law still apply? Cuz the Q/FX45 as well as all the newer 1uz and 3uz-fe powered Toyota/Lexus kinda ignored that. Also, Lexus's new GT car rumored to have 500hp??? I hope they throw the agreement out the window and do what the crazy germans are doing :-D
