Alot of Cressida Q's
|

Hey all,
Hopefully soon i'll be buying a Cressida. I need to know:
1) What are the main differences between a GLX and Grande? More than leather seats?
2) Do all Grande's have an LSD? Or was it just an option? What type is it? How difficult is it to locate an LSD for these cars? How can i test to see if the Grande in question has an LSD fitted?
3) Do JZX90 struts bolt-on to a MX83 Cressida?
4) How hard is the 1JZ-GTE conversion with a JZX81 half cut?
5) What are the 'gremlins' in these cars? All cars have gremlins!
Thanks.

1-For cressida's options : http://www.thermactor.com/forum/viewtopic.php?t=22 12
2-The grande has sunroof, lsd, abs, leather, cd, digital climate control, electric adjustable drivers seat (i think) as standard. As far as i know all grandes have lsd. Its easy to check you dont even have to jack the car up- look for this:
http://www.reanimotion.com/ToyMods/diffdeco.gif
3) JZX90? I'm not sure, AFAIK no they dont.
4) Feedback from others that have done this conversion is that physically fitting the engine is easy, especially if you have a post 1991 model which has a different crossmember design allowing the motor to drop straight in. The biggest drama is adapting the standard loom to run the 1j. You could change the whole loom over, or search the cressida forums for info on adapting the old one-its been done many times before. Other dramas people seem to have is getting the factory cruise control and ABS to work after the conversion.
5) Well the MX83's gremlins are:
-Head gaskets. The life of these can be prolonged by doing a proper repair- making sure the head and block surface are dead flat, using a genuine gasket or aftermarket metal gasket (from the likes of HKS etc..) and tightening the bolts beyond the toyota recommended value of 58ft/lbs to somewhere around 72ft/lbs.
-Other gremlins-Theres not a heck of a lot. The standard auto (A340E) is very tough, being a toyota most things hold together quite well. I've had mine for over a year now (91 GLX) and apart from a head gasket (which was fixed before i bought the car, blew again because the mechanic didn't do a good job, so fixed by me in the last couple of weeks) i haven't had any major problems. Watch for the plastic top tank on the radiator cracking if your car has/ever had a blown head gasket- they're prone to be cooked by the exhaust gasses getting into the coolant. There are minor problems which i'll try to list
-oil leaks from the cam covers (easy fix - retighten or replace seals)
-oil leaking through the distributor (either a new o ring or if its leaking through the shaft (like mine) you'll need a whole new distributor). It doesnt cause a problem though, mines always been like that with no ill effect
-valve stem seals - again this is related to if the car has been overheating or the age of the car. Not really a gremlin as all cars suffer this problem.
-problems with the car idling- eg: too high or too low. This is commonly caused by a faulty idle speed control valve which is usually rectified by pulling it out and cleaning all the carbon and gunk on them that builds up over the years (again easy fix).
They're really a great car. No 'dirty your underpants' speed machine but will easily take a VN commodore in good mechanical condition (at least that's my experience). They're very refined and well equiped, the engine is smooth and quiet (albeit a bit thirsty on fuel)- the suspensions a bit soft but this is ofset by a superb ride.
Get one, you wont be disappointed. Have it checked out by a reputable mechanic for head gasket as a minimum.

Ooops, for some reason I read that as JZX81. You're right, JZX90 struts will not fit.

JZX81 Chaser/MkII struts will fit an MX83 Cressida. Places like ImportBitz get these in fairly regularly.
7M's are getting pretty old now and yes, most of them are a ticking time bomb. Do a search if you want to learn about preventative maintenance, but the best prevention IMO is to be rid of the thing entirely.

The only preventative maintenance is to replace the head gasket before it blows.
By making sure the head and block surfaces are flat, using a genuine head gasket(toyota redesigned them a few times to help the problem) and tightening the bolts to 72ft/lbs would be the best insurance. Once the gasket has been properly repaired the 7M's dont really fail alot more than any other motor.
The bad rep behind them is partially due to the insuffient head bolt torque that toyota recommends, plus the age of motors these days. Any 7M on its original gasket is a worry, but IF its been repaired well, it should last.

My Grande has no sunroof or moon roof, whatever they were called. The 7M is a pain in the ass. The JZX81 front cut is the best way to go for a 1JZ conversion. GLX is lighter but you lose LSD and CD and leather.
Parts can be dear and there is not a lot of aftermarket support for parts, standard or preformance. Having said thaty I've had mine for 4 years and the head gasket only went at Christmas. One of the most pleasant cars I have driven. Have enough poke for day to day driving.

OK. I've heard from alot of Cressida drivers that their cars use heaps of petrol. Why is the 7M-GE in the Cressida shell so thirsty?
Has anyone dynoed their stock Cressida? What A/F's was it running at: full load and at cruise? Print outs?
If it's rich A/F ratios i can tune it out with a SAFC 
Thanks.

7M's in general are thirsty engines, and Cressida's are heavy cars. Tuning will probably help but it will never be light on fuel.

no difference in weight to a MA70 Supra (I think..), with the bonus of 4 doors. Economy isnt brilliant- as one mechanic told me "if you can afford to buy a cressida you can afford to not even look at your fuel bills", it may have been true in 1992, but in 2005 its not the ideal car for poor uni students...
- prior to head gasket fix i was getting approx 400km per 60L tank, with some err..."spirited" driving Dunno what it'll do now.
They are supposed to use around 12.5L/100kms in good nick, but few if any have ever found that especially since the average cress is pushing 200000kms.

...Find me a dyno and i'll show you a run 
I'm not aware of any stock cressida dyno runs, you could try for some N/A supra's tho- prob your best bet.

Mate, no car is ideal for poor uni students. Believe me, i'm one of them.
Being the hipo-crit i am, i've got a Datsun drift car too. Hence the "Vienta for sale"...
A luxury Cressida as a daily, and Datsun thrasher for weekends sounds pretty good to me!
SOMEONE BUY MY VIENTA!

Haha..the irony.
I was looking for a 5 speed V6 camry and ended up with a cressida (i've only had my car for less than a year), there werent any 5 speeds around when i needed them.
Pity you're not in townsville, i'd consider a swap http://www.thermactor.com/forum/viewtopic.php?t=54 51
- $1600 head gasket repair done 50 (yes 50!)kms ago..should last a lifetime!!

I've decided on NOT buying a GLX. The standard LSD in the Grande is worth the extra...
You'd have to give me $5000 on top too (but i'd have to give ya a fuel rebate on driving down here, just to be nice).
Now, back to fuel consumption. What does everyone get per 100kms?
How much does it cost to fix and replace a blown head gasket?

The grandes are in much higher demand, so if you could find a mint GLX you could just do an lsd convo and save some cash. (but you would loose out on ABS, and the leather (which i've heard isn't that good quality anyway).
SEARCH the cressida forums, theres a quite lengthy discussion on fuel economy there. For the record i get about 14-16L/100kms.
As for BHG- cost me $1600 to do myself, using genuine parts and doing the head bolts+ washers, radiator, injectors, battery, fuel filter and timing belt at the same time, plus had to buy a few tools. Should be say $700 for parts (genuine) if you have all the necessary tools. A mechanic will typically charge upwards of $1500 and you dont know how good a job has been done and chances are hes going to use a poorer quality (thus more prone to failure) non genuine headgasket.

Geez, you guys really need to check your driving style. Even spirited driving in a 200k old Cressida shouldn't use much more than about 12l/100km. My WORST was around this. By the way, for those of you interested in the 1JZ conversion, I get about 12l/100 around town and blasting but 10 on the highway, even with a half ton of trailer being towed behind it. No special tuning, or tricks. I consider myself to have a heavy foot and don't mind the traffic light dash now and again.
For the record this 1JZ has a standard intercooler, big exhaust and runs 12psi max.

I didn't mean to be a smart arse. The Cressida (mine 1988 MX83) is a fantastic car and was way ahead of its era. How many cars in it's class were any where near the mark. Maybe my engine had been "looked after" a bit more than most, but at the ned of the day you're right. They are not the most fuel efficient. For anyone who questions the 1JZ conversion and the cost, the thing is awesome and the fuel economy is BETTER than th 7M (considering the vintage of these engines, this should not be surprising). I run an auto, so this SHOULD be worse than the manual, but if I can pull half a ton of trailer (all up approx. 2 ton) and still get around 9 to the litre, then why wouldn't you.
I have read a lot about this conversion over the last few years, and while you can build an absolute killer, my car is everything that I want. Kid taxi, long distance transit (2300km's in 24 hrs) and freely rev's to the 7500 rpm rev limiter. with constant heavy loading and frequent excursions to ht e high side of 7k rpm I would expect the fuel efficiency to be CRAP. BTW I still use the standard fuel pump and this thing is no where near leaning!

Well mines got 168,000kms with strong compression, and a head rebuild less than 20,000kms ago. I found the best i could get was around 420kms per tank (60 litres),how does that compare?
I dont want to give the impression that i treat my throttle like an on/off switch, i'm the same as you - enjoy the odd traffic light dash or backstreet thrashings but in day to day traffic i drive this car like its targetted demographic-an old man.
That figure was BEFORE my head gasket repair, during which time i also fitted a new fuel filter and had the injectors cleaned and flowed (two out of 6 were down on flow before cleaning). My 02 sensor might be a bit old but it has no indications of any problems and i'm not running overly rich mixtures - no significant amount of fuel smoke.

OK, well I can't speak for the 7M, but with the 1JZ, the type of auto fluid has made all of the difference. In the 7m I used Dexron III, flushed with about 12l when I first bought it (castrol). It wasn't until I bought the 1JZ that I started to really understand auto fluids. The fluid is designed to match the clutch packs inside the gearbox.I know a lot of the Soarer guys will be able to back this up. When I bought my engine, the fluid was pretty ordinary, so I bought 20l of Castrol's finest synthetic, Transmax Z. ($250) I thought that this would be the best for a high performance auto. How wrong could I be. After a few shift dramas and "burning" I bought the Toyota Type IV fluid ($25 for four litres) and reflushed the system. The car now gets between 1 and 2 k's per litre better fuel consumption.
I don't mean to appear judgemental, just trying to help people, ht e quality of the fluid and periodicity of changes has a HUGE impact on the "hookup" of the gearbox and as such effects the economy of the engine.
I have since learnt that the clutch material varies from gearbox to gearbox and as such, Toyota had their gearboxes and fluis specifically designed for them. Given the cost of the Toyota fluid (not much higher than Castrol Dexron III) this may be worth a try.
Toyota also recommend a servicing (fluid change) period of 30000 kms on their autos.

Luxury pack option for Grande was, believe it or not, ABS brakes and sunroof. I have a 1990 Grande purchased new and I had to take a sunroof to get the (luxury) ABS brakes. Actually the dealer threw in the luxury pack to get the sale. Hardly ever used the sunroof as I don't like the smell of fumes in Sydney traffic. (and sunburnt bald head)
Cardigan on, windows up and airconditioning on always. Seduced by the quietness in the car.
Have averaged arond 10 to 10.5 litres per 100kms, mainly Sydney, Bowral and running around the city. On many occasions saw over 500 kms between tank fills. Best was 595kms on a cardigan inspired trip to Queensland.
Still a better car to drive than my 2004 company Berlina.
Have been in a state of shock since Toyota stopped bringing them to Australia in 1992-3.
At 60 years of age too old to go the twin turbo route. Bought a Honda VFR800 instead for my late life crisis. Brand new leather cardigan too.

Hi Guys,
I was just doing a bit of research on Cressida MX83s,
in particular the diffs.
To quote Norbie from earlier in this topic:-
All MX83 Cressida's have a G-series diff, and the Grande's have a clutch-type LSD centre. It is the same centre used in Mk3 Supra's and practically all Hilux's since the dawn of time, so diff centres of all varieties (whether factory or aftermarket) are easy to find.
Does this mean that any hilux centre will fit into a cressida
diff housing? Does this include 4WD diff centres?
IF so I have an ARB air-locker fitted to both my diffs in my hilux. Could I purchase another and install it into the cressida housing?
Cheers,
Bart

Awesome. I was hoping/thinking you would say that.
The ARB air-lockers is the best diff upgrade I have
ever done to the 4WD. It gives 100% positve drive to
all wheels and is on/off like a light switch.
This would be an awesome setup for drifting!
These centres are strong too, I have a mate who snapped
2 axles on the same centre and both times refitted the
same air-locker centre unchanged with new axles. He has
been driving for 8 months locked on 38" tyres without a problem.
They are 8.5" and have more splines than a ford 9" so in my
opinion, you will never break one of these onroad with 25" or
whatever car tyres are.
Sweet, can anyone point me in the direction of some more info
for the ARB swap? Anyone tried it for sure?
Cheers,
Bart

your correct in saying they have more splines than a 9 inch however you'll find that they are only a 8 inch diff not 8.5.
Toymoman75 has an ARB air locker in the G series diff under his TA22.
I'm happy with the true Trak limo I have in my F series diff, I believe they makes these units for G series diffs to. (torsen LSD)
