1uz manual and sump fitment
|
Wed, 17 September 2003 14:50

ok, try this on for size
i need a front sump right? yes
will this mean that the rear of the 1uz will sit the equivalent of 2 cyl's further forward than my 6m? (relatively speaking, i realise it will slightly larger than that)
and hence my gbox shifter position WILL NOT match up?
or does the gbox remain in the same position, and the sump just magically fits where it lays?
any help/ideas would be greatly appreciated

the engine remains in the same place - just the sump will either bulge forward, staight down, or to the rear - if I understand what you're asking correctly

yeah, thats what i presumed
so the gbox shifter will be a few inches further forward, and hence no longer match up with the existing hole?
so is auto the only option without spending big bucks on a custom shifter repositioner?

uh
no, not waht I was saying.
the bulge of your sump should not affect the position of the engine, so the gearbox should still match up... assuming it was going to line up in the first place.
you must've already forked out for a 1uz -> w58 bellhousing tho, since the 1uz only came in auto (?)

ok, i see what u said now
but doesnt the bulge of the sump have to slot into the place between the x-member, and the sway? bar?

| BigWorm from another thread |
I needed a housing that sat the stick further back, I must have either the 18 or 19" one, & gave the Castlemaine Rod Shop a call. They deal with plenty of supra 5 speeds, & they charged me I think $40 for the housing & the little cast linkage thingy.
I still havn't changed it yet though, as you gotta pull the bastard box apart to do it......

Thats what BigWorm said when I was asking about shifter positions.

yeah, i do know you can change em
but i am already using the second most right one (second longest one)
and so the furthest most right one will only move it back minutely
unless they build custom ones to throw my shifter back even further.
and thats gotta cost more than $40

The JZA80 W58 has the shifter way further back than that. I haven't measured it but maybe it will do what you want?
Here's a pic of an MA61 W58 shifter housing next to a JZA80 W58 shifter housing:

will that bolt up to any w57/8?
do you still have yours? is it still in good working order?
can you remember how much further back it set the shifter?

Yes, they are interchangeable with some effort. I currently have an MA61 shifter in a JZA80 box, so the reverse should be possible.
I still have mine, but unfortunately it was broken when I got it. If you look closely at the pic you can see one of the mounting arms has snapped off. I can't really give you an accurate measurement because I can't bolt it up to a box.

A front sump is a front sump, it doesn't really matter which type of engine it is. Keep in mind that a lot of Toyota cars have the option of a six or a V8, and so both need to have a sump to suit the crossmember on that vehicle - it's not like they're going to redesign the front end to suit the engine, it's much easier to do it the other way! So if you have a front-sump six in your car, a front-sump V8 will slot right in and the gearbox will line up in the same position.

Absolutely, 100% true...A fact to which my car will attest. (Only modification required to Drive-train was 30mm tail-shaft lengthening...and even that was more a function of where the engine was "positioned"; in other words, it could have been further back - as in the case of Darren's car - and the tailshaft would not have needed altering...)

ok, that makes sense
but say the sump on the 8 for a certain vehicle is a front sump, and the rear of the engine is just shy of the firewall (as is the case in most), then wouldnt the 6 in the same car have a midmount sump, due to the fact that the engine is 2 cyls longer
(i am presuming here that the 1uz is a lot shorter than a 6m/1jz)
and in this case, the rear of the engine will still be just shy of the firewall and hence yes, the gbox will still line up perfectly
but in the case of a front sump on a 6 (ie a 6m in an mx73), and then putting a front sump 8 in the same place, wouldnt this move the rear of the motor forward but some amount, and hence the gbox will no longer line up?
does anyone actually know if the 1uz is shorter than a 6?
i would presume it is as it is only 4cyls long, and the size of each cyl is close to a 6m's
knowing this would solve a lot of problems
cheers

Ultimately what sump you want use will depend on what part of the drivetrain you choose as your 'point of reference'.
If you choose to run a shorter motor but keep the sump in the same position, then you just have to accept the simple fact that the gearbox will mounted further forward. Norbie provides a simple out for you.
If you choose to mount the gearbox in the same position, then the sump will sit further back, and you may well have to revise your sump type or modify it.

ok
its all starting to makes sense now
so, it looks like my only options are either a custom sump ($$$) or to find a jza80 shifter and hope it lines up alrite
me thinks i'll go auto for a while and make a decision on the manual later
cheers guys

well he did ask! 
as for suggestions on what to do... if you want the car to handle better, mount the 1uz as far back as you can - get the weight closer to the centre of gravity.
if you want to make it easy, try and mount it so everything lines up nicely - which will probably require the engine furhter forward.

wow dave - would be GREAT if you could EVER send me some images for the site 
ive got all the bits to convert to the mk4 w58 shifter housing etc if youre after it - but, like norbs- thers a few bits broken on the support arms - maybe between norbs and mine you can re weld bits and make one good as new?
cheers
