Yeah, I got the mag..pretty cool

 

That's amazing considering how they left the displacement at 4.0L. Can't imagine it being bored and stroked

 

Incredible ... over 1000 HP from a stock block 1UZ? And here I thought that only Toyota's 2JZ engine reached such power levels. Looks like the UZ is beginning to gather a following in the aftermarket.

 

Thats what i though, after following so many UZ power adder threads and challanges i found it surreal that this little trans shop pulled over 1000hp with an albiet big blower and made it work i would like to know more details about the build and the management system, but damm 1000hp is 1000hp with a stock block and what seems to be a non stroker with STOCK CAMS

 

I've followed the UZ quite a bit too, and have never seen any UZ engine push over 1000HP on the stock block and stock cams. I too would be VERY interested in getting some details about that engine. The rest of the engine probably has some heavy mods done.

So now the UZ is yet another Toyota engine to add to the list that can do over 1000HP on the stock block.

 

What have I been telling you ppl about Toyota(Lexus) V8s for the longest while?

 

I like you would be very interested in knowing what went into this monster, I mean im pretty heavy into cars and power fi applications not a pro, but i know whats up, from domestics to imports and this is something for UZ supporters to rejoice about especially since it seems to be a streetable combo and not a finicky time bomb, yes it may have some low speed/idle issues that one may not find normal. But not anything that 1jz or 2j swappers dont deal with anyway.

 

LOL... ne1 can make any engine with 1000hp, reliability is the key word...

 

is that like a cadillac catera body?

 

Yes, it does look like a streetable setup. The car has street tires on, interior is practically stock, and the exterior looks very stock and low-key aside from the wheel/tire setup.

In the enthusiast and aftermarket communities, there have been virtually no Toyota/Lexus V8s running over 1000HP on stock block and cams, which is why this story is so amazing. But yes, it does show that now there are several Toyota engines that can reliably run over 1000HP on the stock block.

On that note, I wonder what the UR series of engines will be capable of?

.

Sorry, but not just ANY engine can make over 1000HP on the stock block and using stock cams. Many engines will simply blow up.

The article did not mention any engine problems during the high speed run; only a gearbox problem, which is a Dodge Viper gearbox.

Even the Veyron has quite a few engine reliability problems, and that is a stock factory car.

Fact is, achieving 1000+HP on the stock block and stock cams is very challenging for any engine.

The fact that the car looks to have a street setup in the article, and the fact that no engine problems were mentioned likely means this engine DOES run reliably.

Think about it; if the engine wasn't reliable, then the owner/builder would NOT be running the stock block and stock cams.

 

wow.

thats amazing!

 

I beg to differ. I take it when you say stock block, you imply stock internals as well. This is not the case, as the omega uses Cosworth pistons. I'm curious as to which rods are used, as the UZ rods are fairly weak.

I'd imagine that the UR blocks would be capable of quite a bit more for a decade and a half long advantage in metallurgy and design practices.

 

No no, when I say "stock block" I am strictly talking about the block and nothing else. The article itself mentions the engine had a stock block and stock cams, but everything else is modded or has been replaced with different parts. The rods are definitely not stock. Either way, it's still quite an amazing achievement.

They likely *are* capable of more, but I'm curious as to how much. Toyota developed the UR engines in parallel with it's F1 engine program, so Toyota used much more racing expertise and knowledge when developing the UR blocks than compared to the UZ blocks. For instance, the UR blocks use more forged internals than the UZ blocks ever did. I can already imagine the potential of the UR engine, especially considering what Toyota is doing with the 2UR for the IS-F, complete with titanium valves.

 

^^ Be that the case, the few example of 1000hp UZ I know of are stock blocks. Un-sleeved, un-decked not sure about honing and blueprinting tho
