Lexus Vs. Infiniti

[Sabre_Logos]

I have heard of 800hp vh45 turbo engines with stock bottom end. And I think there is a boat running twin turbo with around 1000hp.

I think the twin-turbo VH45 in the Jet boat is putting out around 800hp, this is supposed to be on stock internals and a fresh rebuild before installation. I don't have much more info on it.

Here's the video:http://www.dynologic.com.au/vids/Nizpro-Speedboat-low.wmv

I've never seen a high rise intake design like that...Wild.....

We don't know if that twin boat motor is stock on the insides.... I dought these motors can handle that much horsepower with the stock internals...If so I would say these motors are "far more" superior then any Xuz-fe motor and the Supra TT motors too....

That would also mean these motor come stock with forgies....???????

The engine in the video has a different intake, and also this video has been around for ages.
still they could have changed I supose.

I was reading on a forum the other day that these engines came with forged crank and rods, and coated cast aluminum pistons. 6 bold mains with a cradle.
But not sure if all the different models of this engine came out with this setup

i seriously doubt this engine can handle 800BHP with those rods, even if they are forged, and cast stock high compression pistons.

the rods are forget, but they are not big rods.

Well if they can handle any thing close to that kind of horse power I will personally blow up my own 1uz-fe motor and swap one of those babies in... Like I said I was impressed with the N/A power with bolt on mods of the Q45 motor...

Can you say bell housing adaptor anyone?

 

[V8Datto]

I think the main reason why the UZ engines are more popular is because of aftermarket support and size, the infiniti's are bigger.

 

[jibbby]

Yep, bigger and more powerful.... I need to google this motor and find out it's true potential....

This is definitely impressive, although that saying its 'only' 400bhp on normal pump petrol. From what I read here though the pre-98 1UZFE's should be able to do that as well on completely stock internals so its not that impressive.

I just like the stock crank girdle :tongue2:
