MA61 1UZ 4WD Conversion??
|
Sat, 08 January 2005 11:16
|
|
A friend has just started a project involving a 1UZ 4WD into a MA61. Has anyone seen this conversion done before?? if so does anyone know of any photos on the web of a completed conversion ?? A huge job I know, just hopeing someone may have done it already to see how it came out.

I think he wants to do something a bit different, he wants to race in hillclimbs & he got the front cut cheap. Its going to run the standard rear suspension and the front suspension from the front cut modified to fit.

just tell him to put a decent diff in the rear of it...
Itll handle a damn side better the 2WD way toyota designed it to...
either way good luck...as im pretty sure you'll need it...

Trying to 4wd a 2wd car is a very costly a slow process.
Better off getting a 4wd car to start with.

Won't be costly coz he's doing all the work himself but it will take a lot of time and effort, and yeh he could go and buy a WRX but everyone's got one of them!

i hope hes got a damn well set up workshop, and knows car geometry like its running out of his ears

Nah, I don't mean a WRX, I mean like a 4wd sierra cosworth.
Something rare.
There's a guy putting a 1uz into one on lextreme.com
What ever you choose, good luck dude.
Keep us posted on the outcome.
If you need mounts to mount the 1uz in the MA61 chassis, I have some.

Yes and Yes. He's no goon. But the Geometry is definitely a hard one as he's had to make up shortened front suspention arms to reduce the track so it will fit in the MA61. I know what your getting at it a very big & complex conversion but he's one of those guys who's more into the engineering side than anything else. But anyway has anyone heard or seen a conversion like this before??

Thanks CrUZsida I'll check it out on lextreme.com. He's had to use the whole front cradle out of the front cut because of the front diff suspension etc. so he's basically mounting the front cradle up to the MA61 front end... lots of metal work.

I assume he's using a UZS14x Aristo front cut? If so, there's going to be quite a lot of metal work involved - I bought a JZS147 Aristo front cut and the front end was vastly different to an MA61!
Should be very interesting if he pulls it off though. An MA61 with big power and enough traction to use it off the line would be something new!

Unless he turbo's (or supercharges) it, the MA61 has more than enough traction for stock 1uz, even a warm 1uz.

traction in any of the 1st few gears would be something new..
if he actually pulls it off, it would be amazing
imagine a 1uz turbo'd with traction..

The front cut was from a "Crown Majesta" sorry I'm a bit new to JDM Toyotas so I'm not sure what an Aristo is.
The conversion is under way so he's going to pull it off but prob only as a NA motor with auto until its up and running, then down the track it going to be turbo'd and made to a manual. Today he had started fitting the front sub frame to the MA chassis.... can't wait till its done its going to be a weapon!!

I want to see me some pics of this. Better yet, where's this guy live, I want to see the project in progress
Of course it CAN be done with some serious work - all the better because of the people that insist it's stupid or can't be done. Bring it on. After all, wasn't it 'impossible' to RWD a GT4???...

it's not impossible... nothing is impossible with car modding. You just have to throw enough time and money at it
Where is this guy located? I'd love to check the car out as it progresses, and when it's finished... just the thought of how long that will take would be enough to give me nightmares!

The big problem with his plans down the track is that I am sure the 1UZ 4WD never had a manual box available.

It MAY have been used in 2uz landcruisers, but just use it out of any manual landcruiser, and get a CRS/Dellow bellhousing.

wouldnt that be an oddly geared box for a race car tho?
is it possible to change the ratios in a gearbox?

A 4wd box will be well suited to hill climbs.

I'm pretty sure the 1UZ 4WD runs a diff in the sump much like a GTR. That box you've listed is for a 4x4 style car rather than AWD.
That's my understanding at least. Mind you I've never seen one much like the vast majority of people here.

I thought the 1uz/gtr diff was just at the front, and not physically INSIDE the sump.
And that only the axle passed through the sump?
Otherwise how do you get the power from 6" to the side of the gbox, straight forward, into the sump (which coincidently has a gbox directly behind it), and out to the side.
Please correct me if I'm wrong, as my understanding is basic.

A Landcruiser box is no good for this application as it has no centre diff. As mentioned he will need a proper AWD gearbox, and to my knowledge Toyota have never made such a beast (not for a north-south engine that is).

Manual Prado's still run fulltime 4wd's. (at least the auto's do).
Find out what box they use, and adapt that.

If you don't have any webspace given to you by your ISP (most give you 10-20meg), then sign up at the lextreme forums, and upload it there.
Everyone can.
Failing that, email it to me (PM me for my addy) and I'll upload them for you tonight.

The setup is very much like that from the Holden Advantra/Coupe 4 where there is a planetary tarnsfer box on the baclk of the gearbox and the front diff is alongside the the engine, and the axle passes through.
It would take a shitload of sheet metal work to get the trans in the tunnel, but along with the rest of the conversion, probably pretty easy.
If you need some pics of the Holden setup (for comparison), let me know and I'll get some up
Bill Sherwood also had some pics (and I think he has an engine as well) as he is harbouring some AWD plans....

I am assuming that that is an auto in the photo, in which case why not use a supra box with separate transfer case strapped to the back of it. This is effectively what the old 4WD Hilux's had wasn't it?
You already have the sump/diff which is the hard part. surely the gearbox would be a matter of getting the right bell housing and bolting it on.

Most Hilux's and Landcruisers are 2wd, or 4wd.
They are not fulltime 4wd.
You need a fulltime 4wd box as it runs a centre diff.
Hilux's and Landcruisers dont run centre diffs (as pointed out by Norbie).

Don't the current V8 Cruisers run full time 4wd?
If so they would have a centre diff, with a locking feature.
Dunno how the front axle layout is though, but the upper models have independant front suspension, so the 2UZ may be setup the same way as this 1UZ.
This setup also looks the same as the Nissan GTR & Ford Cosworths.
If you use this gearbox, I want to see a first gear low range burnout from all 4 wheels after its finished

If so they would have a centre diff, with a locking feature.
Dunno how the front axle layout is though, but the upper models have independant front suspension, so the 2UZ may be setup the same way as this 1UZ.
This setup also looks the same as the Nissan GTR & Ford Cosworths.
If you use this gearbox, I want to see a first gear low range burnout from all 4 wheels after its finished

It wont be very impressive id be lucky to get 20km/h out of my car at 7500rpm in 4L and 1st gear

Hats off to the guy if he gets it done.
I looked at this setup for the GT8 and 2 things killed it. Too many compromises and a big unknown as to whether it would handle 300+ kw at the wheels....i suspect not.
He'll need to run the correct rear diff ratio as well ie the one that comes with the front cut...or he won't get far down the road at all.

New photos coming soon... The front rails have been worked over and the subframe is almost in place and he has decided to go all out and twin turbo it!!! Stay tuned

alan, i think using the word flight was very appropriate considering the description of this vehicle...
