2 UZ FE dress'd engine weight - '05-'06 -

[milnersXcoupe]

I'd read:

2 UZ FE shortblock weighs 240 lbs.

1 UZ FE shortblock weighs 160 lbs.



What is the 'drop in' weight of dress'd engines ?


There is alot of concern about the 80-82lbs. difference
between the engines - which in most American cars doesn't
matter until you're hitting 580lbs.+

I'm replacing an engine that weighs 540lbs. - iron head / block - .

A couple of other points to ponder:

1. In the Toyota technical literature it states the 2UZ has a "steel crankshaft". In the same literature it also states the 1UZ has a "forged steel crankshaft". Hmmmm, typo error, or not?

2. Don't forget the differences in coefficients of thermal expansion between cast iron and aluminum, when setting up a 2UZ motor for high boost and high temperatures. You sure don't want the head gaskets shifting around and coming unstuck, ala the MKIII Supra's famous motor "The BHG Special" (I owned one).

Cribb Notes

Cribb sports another 'mull-it'........:smokin:


Steel crank - Forged Steel crank ......... steel being operative 'street slang' for Forged, Toyota underplays the 2 UZ and the 2 UR in print - but who chose the Uzzie-2 to go racing with - this http://tinyurl.com/2sdl4u 'Truck' engine ?

Toyota uses 'Compacted Graphite Iron' in their Iron blocks - NASCAR block included - not boiler scrap iron.

Anyone remember the 4 cam HEMI project MoPar had
back in the late 60s ?

David's .jpgs of the 2 UZ block - with belt covers off, is a mirror image of that engine - MoPar Fans begged to have produced.

Harmonics & Vibration ruled out production - fractured the cam bossings.

Claims that development and materials upgrade would have brought production costs of the engine into astronomical was reason given for 'mothballing' the design.

Enter 2 UZ FE:

So here's the MoPar 'Dream' Engine - with an oiling system that doesn't require a belt driven pump - wet sump - to survive, as does the Ford 5.4,
doesn't have 'hot spots' - or 'heat problems' in the heads, as does the Ford DOHC 5.4 and whose block is 20+ lbs. lighter than the Ford 5.4 NVH - with the bore of the Cobra Aluminum Race Block - and is available in salvage yards for under two grand......what's with the groaning about 80lbs. over a 1 UZ weight?

Move the battery to the Trunk ?

I'm tempted to go 'bone stock' - as upgrades to my LS430 A761E six speed are a must - trans then good to 9.99sec bracket.

But the valve train can be made to handle 9,000 rpm with $300.00 in springs
and the oiling system has zero complaints - totally amazing - rods and pistons are going in before fitment of the engine to the car - a small price to pay to begin to awaken this sleeping giant.

I want this thing to 'sing' the 'R's like 'Ella'.

Turbo ? ....... a good single 'driver snail' can be had for $600.00:

www.mjmturbo.com

yet most of Turbo costs are the electronic controls - to be able then to 'Dial -a- Boost' at will.

But Turbo isn't in this first hand of cards - just rods / pistons / ARP suds,
then Option 'T' is on the Table with this jewel.

Car shows - some weekender's to Rockport Mass. and Jersey Shore rather than wheelie bars and 10mpg tells me a pump gas build plan is required.

Compared to what you'd need to put on your average American V8,
to 'get it right' - roller rockers , pushrods, girdle, guide plates, intake, carb/EFi, roller camshaft kit, rod/piston upgrade, oil system mods, upgraded pump, cooling system upgrades, block mods, harmonic balancer upgrade, valve seat mashing spring pressures - just the roller cam kit alone is over $1,200.00 - and you have what........ ?

This Uzzie-2 engine sounds 'Awesome' - revs 'Awesome' - looks 'Awesome' in stock form and with the Tech reads available on this 'Awesome' Forum, I am going to have that 'Dream' engine I ogle'd as a kid on the sidelines those many lifetimes ago - and not go broke doing it.

One thing you'll soon learn about Toyota and their technical literature is that when they call a spade a spade, that's really what it is.

If the 2UZ had a forged steel crank, Toyota would have said so in their technical literature. Since it doesn't say so, then I believe it has a cast steel crank.

But who cares?

AFAIK, no one has had a crank failure.....yet. Plenty of 2UZ rod failures - Wayne R can testify to those, but his crank held up fine. Wayne should be chiming in on this any time.

But it begs the question, why would Toyota put forged steel cranks in their aluminum block motors (yes, their literature says the 3UZ has a forged steel crank too), but put a cast crank in their iron block 2UZ? Did they feel they needed extra strength, rigidity or ??? for the aluminum block motors? And was the cast iron block sufficiently strong they didn't feel a forged crank was warranted?

Or is it just a typographical error, and the 2UZ really does have a forged crank?

Inquiring minds would like to know.

I'm sure someone here can take a look at a 2uz crank and look for some of those eye pleasing wide forging marks.
