Cryo-treatment will not extend your engine life 100%. It will in some cases enhance the durability of Ferrous parts, but it should be done right after heat treatment as the effect is much better on new parts than used parts.

Put em on a boat and send em back to where they came from. If you can't live within and conduct yourself as a productive member of society you should be deported, with a quickness. Of course if that boat happened to "hit an iceberg" and sink, well no great loss. Justice should be swift...

Too bad the BMW engine and parts are so expensive and heavy.

Yes and you too can have such exceptional performance for the oh so low price of $14K USD. http://www.crateenginedepot.com/store/LS7-Crate-Engine-Small-Block-17802397-Coming-Fall-of-2005-P930C0.aspx

Hey that is cool as hell. See if you can get us some quality control rejects for coffee table art. I figured some sort of coatings were used to keep the gauling down, just wasn't sure what type. Supposedly Some teams are experimenting with removing the big end bearing and coating the rods...

From what I understand the 4.0 block and crank is good for a couple thousand HP in a drag application.

one thing to rememer about Ti it doesn't like to be rubbed on. It gauls easily. Until a few years ago Ti rods were strictly race only for durabilty issues. I am not sure how the manufactures have gotten around that. Supposedly Carrillo is working on some steel rods that are lighter than...

Another possible perk to running such a current engine is the possibilty for some sponsorship help. Many manufacturers like to see their currnet offerings in the winners circle.

The race ready LS6 engine from the C5R weighed in at 369 lbs. From What i understand the Lexus weighs in at 425-479lbs. The LS1-LS6 has much more aftermarket support. Now don't get me wrong the Lexus motor turning 10K is fabulous, The LS1/6 has more cubic inches right of the gate. I would...

One thing that just occurred to me is the possibility of weakening the main bearing saddles and tunnel could occur if too much material were removed for the sleeve insert.

What do they allow for a pushrod V8? An LS1 would be much cheaper and it is lighter than the 1UZ. If you don't get that much of a break, then the 1UZ should make more than 550+ at 11K. I have no doubt that in unresricted race trim, the 1UZ can produce 700+hp. This will require lots of...

How did they get the 5.0 out of the 1UZ?

The reduce rotating losses, correct, but in and of themselves they really don't free up that much HP. Unless you are running a carbon fibre driveshaft, aluminum, flywheel, lightened crank, gundrilled axles, manual transmission with straight through final drive, lightened rear gears, lightened...

My bad it wasn't the Coates system but the Roton System. I tend to like the Roton system a little better. Check out www.rotonusa.com

Race Engine Tech has covered the Coates rotary engine in several articles, Looks like a very promising technology. One problem with the rotary valve is the vectoring of fuel air mixture into the combustion chamber. But you can eliminate the inertia of the valvetrain. This is one of the major...

I just though of something else. The Daytona Prototype engines: LEXUS (TRD) 4.3L V8 Bore : 3.545″ Stroke: 3.300″ Minimum crank weight: 38 lbs Maximum compression ratio: 11:1 Cylinder head intake runner maximum volume: 139 cc’s Cylinder head exhaust runner maximum volume: 81 cc’s...

Titanium rods will not make any more HP than standard steel rods in a normal street application. Although your car will feel much faster because you just came of all the wieght of that money for the rods. IN a race application you can make more power by being able to rev the engine higher for...

I agree the 1UZ is way underdeveloped. There should be more support for it, but unfortunately the SC400 is the only car with the engine installed from the factory that is worth building up. The LS400 is a grandmas car. If we could get more people swapping the engine into other cars then maybe...

The stock rod ratio for a 2JZ is 1.65:1. If you had a rod stroke ratio of 1:1 you would have a maximum piston speed of 8153fpm with a load of 6515 lbs at TDC. Those figures drop to 7597fpm and 5527lbs for a RS ratio of 1.65. They fall even further with a RS ratio of 2.06. You can not have rod...

That rod ratio is aweful. You want no less than 1.70 for most applications Stock is close to 1.75 which in many circles is beleived to be perfect. I probably wouldn't go more than .030 overbore on a 1UZ motor. I don't know much about the 2UZ motor. the 2JZ has more power potential under...
