=You're Starting with the Wrong Engine=
You're starting with the wrong Lexus / Toyota Engine:
The 1 UZ FE rods are junk - as are most all the
Toyota / Lexus engines.
Plan on a set of MANLEY
con rods and some Forged Pistons - like CP or
Venolia - with a 'Turbo' ring paak.
The crank of the 1 UZ FE is 3.25" - same stroke
as NASCAR - good for 8,500 RPM - .
Problem being - you have to spin the hell out of
the Blown Uzzie to make power - and you want Torque
not RPM.
You can only stroke a Forged crank .25".
Bore is ? You can't 'bore out' the 1 UZ.
The Toyota engine you want - outside of the NEW
5.7 'Killah' - which has a 4.00" stroke / 3.70" - 94mm bore
and Alum. Block / Heads - Is :
The engine that TOYOTA used in their Formula 1 cars:
=Toyota Tundra 2 UZ FE=
2 UZ Iron block - can take tons of TURBOCHARGING -
2 UZ Alum. 4 cam heads - that FLOW WAY much better than the
1 UZ FE in ANY form.
The 2 UZ engine IS the Lex/Toy engine for FI > forced induction.
The 1 UZ in the know - are hanging 2 UZ FE heads on their
shortblocks - and secretly wishing they didn't have their monies
tied up in a 1 UZ block.
2 UZ Crankshaft is 3.33" Forged unit - add to that a .25" stroke job
and you're 3.58" in the Torque game - bore is 91mm.
Just hone the cylinders - do not bore it out.
Yes - the engine will take 7,500 RPM all day long - their
oiling system is A-1.
Forget belt drive Superchargers - they heat soak the engines -
and the Harmonics they drive into the crank kill off your bearings.
The 4 cam LINCOLN Navigator guys were losing bearings and having
their crank mounted 'cryo' oil pumps EXPLODING due to the harmonics.
For a cure - they went to an external pump with wet sump.
Yeah.......... blah blower in AU... ya da ...... woo-hoo...... bad ideas still run - besides..........
Run a single Turbo with a 'Dial - a - Boost' -> 9 to 1 Forged Pistons &
you'll have a nice throttle response around town - instead of having the engine 'BLOWN' and *TWEAKY* on your way to 7-11.
BLOWERS and TURBOS LOVE GASOLINE - lots of it when in use - so a
'variable boost' situation is preferable.
Most of the Lextreme builders run Turbos - or are switching to Turbos.
check with Jamie for a nice 'Torque' Turbo @:

AND....................
by going with the 2 UZ FE , you can get the 4WD Trans. attached by the Factory!
- TOYOTA TUNDRA -
2 UZ FE
Keep your Lexi intact as a back up parts chaser
and enjoy the beauty of 'Quad Cams' ....'year-round' !.
Check the car Auctions for a wrecked Tundra -
the usual way to install these is by obtaining a
'half cut' - the front half containing the wire
harness / ECM etc. - big pita wire job - .
I have a .pdf of the wire
diagram - I downloaded it from a builder
who did the swap - so should you use
a Toyota engine / Trans.- eMail me.
For the money - can't , since now I'm bed to chair.......[whine],
I would purchase a '01 to 2004 LINCOLN Navigator NVH
6 bolt main block -
DOHC 5.4 'NAVI' engine -
install MANLEY rods / Venolia Forged
Pistons - run an external oil pump with the wet sump,
a rack of motorcycle valve springs / RACING mc locks / keepers
and run a TURBOCHARGER on top.
STOCK 5.4 crank dampner - not - a 4.6 item.
ARP stud the mains / heads.
Bore is 3.55"
Stroke is 4.17"
330cu.in. 'Hot Rod Lincoln'
Engine will spin 9K RPM if you choose -
the 'sound' is straight 'TwIliGHt zONe'
HP / Torque is 800+ with 'boost'
310HP stock - which is plenty really once you
check the TORQUE this thing throws out -
Fully dressed engine weight is 660lbs.
My AMC 360 shipping weight is 740!
Buying gaskets and seals 'n such is
easily half $ you'd pay for Toyota parts.
Navi 5.4 are Chain drive cams - like the NEW
Toyota 5.7.
Tundra 4.7 are 'Belt Drive' and interference
valves > read< one mistake on overdue belt
change and good bye investment.
Tundra 4.7 is a 4 bolt main block - still good
to 1,200 HP ~! but...... a 'Navi' is a 6 bolt main block.
The NEW 2006 Navigator 6spd. 4wd trans. is
a ZF 6hp26 item - nothing but rave reviews
from users > Maserati / BMW / Jaguar / Lambo etc.
and - you can pick up a 'Navi' for HALF the $$ of a Tundra -
like.......maybe $1,200.00 ?
NEW 6spd. 4wd trannies dial in just around $1-1.2K off
www.car-parts.com
'01 - '04 'Navi' heads are a cross between the HUGE intake ports
of the 'Navi' and the '03 / '04 COBRA supercharged exhaust ports -
".....together at Last.....!..."
Just a stock 'Navi' and 6spd 4wd trans. would be under $2,400.00
for a DOHC 5.4 with a 4.17 stroke ?
Oh@~~! failed to mention:
the Engine ECM is 'seperate' and hangs on the Firewall
INSIDE the engine compartment > you get it ALL -
Engine / Harness / ECM in one neat package from the seller.
Engine is wide - 32" at the rocker boxes edges - but manageable.
Here's your 'Homework' :

Go there - read the SVT/DOHC and 5.4 threads.
If you've enjoyed this post > I'm in need of a healthy
