I have a JZX81 half cut
|

Hey all,
Ive been a long time reader, never a poster, mainly due to my owning of nissans (rb25 aussie r31 and atm 4 door 32 with a few mods) and knowing very little about Toyota's....
But now I have gone and done something crazy - I have got my hands on a 1JZ JZX81 cut - r154 box, short shifter, suspected a/m clutch , pod filter, and it looks like it may have dumps already
Anyhow my question relates to the second part of the equation.
I have the ability to get my hands on either :
a) a MX83 cressida in rare factory black , currently 7MGE Auto
b) grabbing a N/A 20 series soarer
My preference , honestly, is the soarer, mainly because i think they are a better looking car, have irs , and are probobly easier to find mods for to begin with.
However, a few people have said to me I wont be able to fit the 81 cut in due to differing reasons ( some say sump, some say mounts) into the Soarers. So for simplicity reasons.. id go the cressida.
Therefore
1 - is it feasible to fit a jzx81 cut to a 20 series soarer with ease? do i need to do any major mods to fit it?
2 - if I go cressida , is it possible to also source a jzx81 rear cut and chage the entire rear end to irs, thus allowing me access to lsd's , coilovers etc, or is there simpler answers at home here in Aus?
this may have been covered before, so i apologise, and thank you all for your answers and time up front. Im struck down really hard with the flue atm, and am stuck at work so searching for hours isnt overly feasible. Ive only got a couple of days to decide too.
cheers,
TJ

The Cressida SHOULD Be IRS. I have heard of some with a solid rear axel, but I have no idea why they exist.

I was under the impression the Aus ones where live axle..
like i said my toyo knowledge is lacking.
Last year there was a import jzx81 for sale here in WA
ex diesel with live axle... i simply assumed Aussie models copped the same?

All ADM ones, are IRS, and if you get your self a 'Grande' version you get LSD as standard.
Also I believe that the black ones were used as funeral cars? I remember reading something like this a while back, so you might want to get it exorcised

Custom mounts are pretty easy to make, so the Soarer shouldn't be a problem in that regard. Any conversion is going to be a bit of work so you may as well pick the car you like best!

pimping is the only way. MX83 - do it.
I have reasons for this suggestion:
# 4 doors - mates, girls, family (heaven forbid that happens to me one day...), booze, etc can all fit sooo much easier.
# Sleeper - police, dickheads, theives etc will not pay excessive attention to you
# Parts - MX83 is aussie delivered, and thus parts will be not too hard to find.
Either way, its a good choice.
Welcome to the light side of the force

All MX83's have IRS.
The Live axle versions (one of which was for sale on here a while ago?) to my knowledge are LX80's i.e. import diesel powered cressidas of the same shape.
As norbie said, you might as well make life easier for yourself and get a JZA70 cut if the soarer is the way you want to go...this is by no means saying that you can't fit the JZX81 engine into the MZ20, it is just more work.

As already said MX83's Grande's has LSD from factory. It's a G series so you should be able to get an aftermarket LSD (such as a trutrack easily as well if you desire).
For suspension there is stuff available.

An LSD centre from a MA70/GZ20/Hilux is a direct fit. You can also get aftermarket LSD's.
Suspension is easy, get JZX81 Chaser gear from Japan. John from ImportBitz will be able to get you some.
Also check out my brake upgrade for the MX83 front end.

Good to hear JZX81 collies fit , as I can source stuff from japan with ease.

Whoever told you that is smoking crack. The Grande has the same G series LSD as the Supra/Soarer/Hilux and they're very tough indeed.
As for the tailshaft, you'll probably need a custom front section to suit the R154, unless an MA70 tailshaft happens to fit?

They aren't the same length (auto/manual), what Norbie was saying is that you may be able to use a MA70 manual tailshaft as it may be the right length...

Ah ok .. it makes more sence now.
However, I believe the cut comes with front half of tailshaft so that should be a help
If not time to do some parts digging

Most front cuts come with the tailshaft chopped off a couple of inches past the yoke, which isn't much help really. However if yours has the whole front section of the tailshaft (including centre bearing) you'll be laughing.

last conversion was a R34 GTT gearbox behind a rb20 in a r32 .. went a two piece, and it lasted 8 weeks...

I have a 2-piece behind a 400hp 2JZ. It lasted 2.5 years before one of the uni's let go. Your Skyline obviously had problems but I wouldn't leap to the conclusion that being a 2-piece shaft caused the problem.

Getting a tailshaft for your conversion is goning to cost you, if you get it done properly
There are no tailshafts that are going to straight up fit if you make a cressida 1jz. However a soarer 1jz+r154 may fit with a manual 1jz tailshaft but I can confirm this.
A two piece custom tailshaft can set you back 1000-1600 dosh. and make sure you get your hands on a 23 spline input as these aren't easily available over the shelf.
Also expect the uni joints on tailshafts this age to be flogged. 300-600 dosh to drill and fix.
I think, the most expensive part of my gearbox conversion.

Did you get many quotes?
My diveshaft cost $300 and that was brand new, the whole lot (uni's & both yokes) single piece!
I think Norbies was only around $450-500? for his modified two piece hilux haft....
$1000 sounds like a lot for a driveshaft

you can get away with the ma70 front half and mx83 rear half of the driveshaft to fit the r154, the r154 needs a bit of a tunnel bash to fit in the x83 chassis
better yet if you can source a jzx81 driveshaft it will fit fine and its beafier than the stock mx83 one.

Modifications: $250 including new centre bearing.

For sure.
I had my wallet extracted out of my ass. Veem was probably the worst joint I have dealt with.
The first day I got the tailshaft back they had put on a 21 spline. So I takes it back and they wanted me to pay for the change over. I got furious when I told him that Veem were the people that told me I needed 23 spline in the first place.
From memory I needed a new centrebearing, new unis (all) and the tailshaft lengthened. He wanted to use old or spare pieces around the shop but only wanted to know about $100 off the price so I told him to forget it.
That all being said the tailshaft is perfect.
A few other driveline places turned me down at the door.

dumps are definatly worth it, the stock ones are pretty restrictive. PM Petes Pipes and ask him about them, he makes 1j MX83 dump pipes.
I've got a walbro fuel pump of some description, and it works perfectly, but I'm sure someone else can explain about fuel pumps better than I can.

90% of new Walbro's sold for less than $170 off ebay are FAKES.
I doubt many places can get them cheaper than ImportBitz, who sell for $170.
All genuine Walbro's are stamped with a big "W" and all have an individual serial number on them.
Its most likely these fakes that have failed in your mates cars.

Im well aware of what the deal is with fakes and real walbros
my personal experiences have lead my to choose to not use one this time around. Ie I have owned one in my rb25r31, and it wasnt a pleasant experience.
Id rather pay more and live in peace.
My question should have been is there a direct bolt in for a cressida?

Yeah its well known that the factory 1j dumps are fairly restrictive , from what ive heard they are a worthwhile upgrade i beleive theres ~20rwkw gain to be had from a well made set of twin dumps. It would be easier to do this upgrade while the engine is apart too , as you wont have exhaust .. etc connected.

Heya all
Ive taken delivery of my cressida - i can now see why they are so highly rated ! smooth refined quiet, everything the other family cars of the era wernt.
Took it for a bit of a drive - and jesus they are a boat to drive stock ! ride height more suited to aviation purposes, and not alot of composure, though as ive just come from a modded skyline, it may be being a little harsh here
So a few new questions -
1 - what do you guys do for suspension ? Is simply getting lowered stuff with some stiffness in it ok ?
2 - how good is the standard lsd? just looking at the prices of aftermarket stuff, id say factory is expensive enough !
