ed - there's a guy on msextra.com who's MS'd a 1UZ - he might be able to provide you with a screenshot of the AFR target table he's using.

He's a south african guy - see his MSextra profile for contact details.

Any good?

nah - thats just service specs man - nothing usable in there.

need someone with a disassembled stock non-vvti engine to throw some verniers over a few bits

Jeff, (Jeffro_RA28) on here has a 1UZ short block disassembled, I'am sure he could measure a few things for you.. I'll get onto him and tell him..

Cheers Trent

He could if he wasnt away on holidays i was around at his work two days ago and told his boss apprentices shouldnt get holidays!hahahahaha

Bore 88.5mm
Stroke 82.5mm

I'm pretty sure the bore is more like 87.5 mm mate.
I can check a little later if you like, I have one in pieces downstairs.

[mrshin]

I suspect Bill is correct from memory - I too have one in pieces I might attack with the calipers later on.

[kingmick]

split it up so its not such a painfull job!
someone do short motor, someone do heads and intake etc

[sideshow]

i have a factory crown 1uz workshop manual
when i start work again ill have a look at what info is in that
its in japanese but measurements shouldnt be to hard to read

[ed]

sorry bill youre right - thats my bore...

the specs are to go towards an engine simulation run in prof blairs 4sthead software by an american race team engineer (not sure on what series though) and also in 4 stroke design.

any help would be much appreciated!

cheers
