Hypothetically.... 1UZ 3.5Ltr

The 1UZFE EGR Delete Kit is available for sale here.
Advantages of destroke would have to be higher revs? being "Over square" on the bore/stroke ratio? Maybe less torque but increased HP..(on NA)?

Ed - found a place around the corner in Seven Hills that can offset the crank without grinding. Mind you, they're just out of the phone book, not a!
is that wilkins? then id give you my thumbs up for him too

also, fwiw, as far as bellhousing patterns go, all VZ engines (1-5) have the same pattern. funny enough, so do the MZ series.
 
More hp is nice... but tq wins races...

Ed - not wilkins, though he is on my list to call! It was St George Crankshafts on Bearing Rd.

All VZ engines - OK, time to do some more reasearch on wtf a VZ engine is, what they came out of and what sort on numbers they put out... and most importantly, how much to buy and modify!
 
the 1MZ-FE (local camry 3.0L V6) is a 1UZFE with 2 cylinders cut off - but being FWD it may have a few differences.

there is a V6 performance wing on this forum organised by Toysrme - PM him for details.
 
That can be check with Volumn measurement via the sparkplug hole,something like that.

IF i remember well, they put a cylinder to BDC and fills it with a special liquid exactly 1CL3 for 1 CL3 (something like that)

then they put the same piston to TDC and fills it again, substrac combustion chamber to total cylinder displacement and you've got you displacement. X8 and you got total engine displacement.

Didn't know they'd do this to off-road engines like that.
 
sounds complicated, and how can they can tell the size of the combustion chamber. Does this also require the engine being on compression stroke so the fluid doesn't go out the exhuast vavle. Are they really going to do this to you?
 
Interesting - Ive seen something similar in speedway. Not what we use though.

I dont know the practicals of how the system we use works, but I have seen it done - tube thingy inserted into spark plug hole that has a tube going to another tube thingy (air chamber?) with cc markings on the sides.

Inside the chamber is a floating ball which measures the amount of air flowing out of the spark hole when you turn the car over with the ign off.

Not sure how it releases air though, the definately crank the engine over a few times just like a compression test.

I also know its also not 100% accurate (its been a point of contention before) but I'll have a registered scruitneer inspect the crank to prove that I have a de-stroked crank. That combined with the bubble test should be enough. If that fails after the race I'll take the head off and bloody well prove it!

Mind you, this is a hypothetical engine anyway...
 
Bottom dead center = piston to most bottom spot so you have full cylinder stroke with the combustion chamber

Top dead center = piston to maximum stroke lenght, that means you've got no displacement, only the combustion chamber (space between the piston and the head)

displacement is the amount of air the engine can fill with between TDC and BDC
 
forgot to say, you might have to remove the timing belt or a rocker arm for push-rod engines so yes, the fluid does not go trough the valvetrain.
 
how bout a nsx engine and box. big hp, no stuffing around mating gearboxes, engine work, cams or any of that stuff. i amagine it would be cheaper than a destroked, cammed and headworked 1uz. if you can find one that is.
id probably go either a bored out camry motor or maybe a 300zx engine, as these would be cheaper to replace if they blow up completely. the non turbo 300z engines are far less sought after too.
 
Engine will be rear mounted, transaxle
Buy one of the transverse v6's, buy an E-153 M/T, either from the Camry platform & swap the linkages, or from an MR2 & deal with slightly short ratios & mate one of the avalible mr2 LSD's on it.


The mz is not based off the uz design. Completely different engine family, completely different parts, etc.


I'm sorry rivmasta. It's just the more you talk, the more I see atleast some of the bunches of v6's as a better fit than a 1uz-fe in this case. Tho I'd take a 1uz-fe to play around with any day over any of the modern v6's without thought!
*All* of the v6's going back to the early/mid 80's use the same basic bolt pattern. A v6 will bolt to anything in what I call the "medium" class. RWD/Transverse, no big deal.

With Toyota it wound up being 3 basic bolt patterns.
You've got the small engines.
Then you've got all of the 6 cylinders bolting together (Plus the 3s-gte & maybe a niche of hi-po i4's) With minor differances. (Swapping rwd onto a transverse means giving up one bolt - eh)
Then there is all of the misc things.
 
Cant go NSX gearbox - they go bang to easily in offroad, its been unsuccesfully tried. NSX engine might be fun, will look into that as well. MR2 gearbox - nobody has really tried it, but unless its got heaps of available ratio's (gears as well as diff) and is a proven strong box when copping real punishment... Think rally then triple how rough it is.

On the weekend at the Milbrodale Mountain Classic (Hunter Valley) there were 60 cars started, 21 officially classified as finishers, but only 12 that actually finished all 200km of racing over the weekend. Its tough stuff.

The UN5 we've got has more than 10k of custom gear put in it so far that we know is damn near bullet-proof, is all short ratio and only weighs 60kg, so we'll be sticking with that setup.

But to get back on topic, for the cost of a crank regrind and rods It may well work out the cheapest option for us if they do go 3.5L, we might race with that for a while whilst putting resources together for a race version of some type of V6.

hehe - weird 1uz pattern? damn! so I cant just bolt up a toyota v6 to my existing adaptor...
 
At best. I can tell you that the v6's need an adapter plate to mate to a W58 transmission. You gotta remember man. Most people with a 7m-gte, 2jz, or uz are not going to swap down to a VZ, or MZ block v6 LoL!

VZ's & MZ's came in every v6 powered Toyota/Lexus from the mid 80's through 2005.
Anything built off a Camry. All of the truck/suv's chassies from 87 on up minus the land cruiser (Avoid the 3vz-e that came in the 87-95 truck/suv's like a plauge. Horrible exhaust crossover superheats the heads, weak gaskets & SOHC - nasty. It is NOT to be confused with the 3vz-fe) - they replaced the 22r-te with the 3vz-e.




Personally. I would be taking a hard look at buying a 3.4L 5vz-fe for around $1500usd.
 
Have you thought about the early (pre 1uzfe) toyota V8. I think they were called a 4v and a 5v? They came out in the mid 90ies I think and were 3.5 litre from memory. Saw a couple advertised by japanese wrecker a few years ago. I think they a pushrod though?
Anyone know much about them. I believe they were popular with hot rodders.
 
they are 3.5L i believe and i think they came out in the 60's i saw a pic of twin turbo in a celica. They are pushrod engines, but worth looking into.
