MX83 Cressida inherent problems

Been thinking abour purhasing a Cressida but have been put off by people about their inherent problems with heads.
What can be done to fix this? I've heard there isn't much you can do, is this correct?
Also, are there any other problems with this model of Cressida that I should know about.
Cheers!

Oh yeah and what other engine conversions are possible (other than in the articles section) specifically non-turbo, although s/c and turbo aren't out of question. Just need to keep fuel costs down! Is there somewhere I can find out economy figures for Toyo engines?
What about the non-turbo Supra engine? Would these cost a bomb?
Note I dont need a machine just a reliable cruisey car
Sorry bout all the questions
Thanks again

Of course there's heaps you can do...Start with the easy stuff like putting a 1U/1J/2JZ in it  . (Or, you can try the really hard stuff like getting a Metal Head gasket (MHG) and having the head torqued to above factory specs - plenty of the people here will know exactly what it should be torqued to...)

Another problem is cracking thru the diff cradle. A couple of the guys here have experienced this problem.

Another thing I forgot can you let me know roughly the costs involved and estimate the power gain by modifying the original or doing a conversion

my Mx83 Cressi has done 230,000km's. and its still going strong. it has been regualrly serviced and cared for!!!
i havn't had problems with the blowing of head gaskets.
yes our diff cradle did crack. the whole rear sub chassis had to be replaced. but that only cracked after around 220,000km's. cost about $1500 to fix, thats 2nd hand sub chassis, other small parts and labour. i got pics of the whole pack end pulled apart if anyone wants to see!!!! the the biggest repair i have had. nothing else big.
IMO they are a great car. drive beautifully, the inside it still looking very new, and comfortable. they got a nice bit of power when u step on it. economy wise. driving around the city i et about 400-450km's per tank. well over 500k's on freeways.

So a cracked diff cradle is on the cards if you're doing a conversion then.
That's some thirsty economy figures. I thought they were about 12L/100kms City
9L/100kms Freeway

i am not sure how common the crack in the diff cradle is.
my mechanic, who owns a cressida, and has worked on and serviced heaps of them, has never seen the crack happen before my one.

but i really think they are great cars, espeically for the price u can get them for. they come with every option u can want. power everything. only option u might not get would be a sunroof.

Agree with what you're saying I think they're value for money. So when you say abt 400-450kms on full tank are we talking the whole 70L or do you have say 10L left cause that makes a bit of a difference when working out figures.
Based on 20,000kms a year and $0.80L
450kms/70L = 15.55L/100kms = $2490
450kms/60L = 13.33L/100kms = $2130
Also, anyone run their Cressida on LPG?
Is there a bolt in besides the 7MGTE?

If you get a JZX81 front-cut, its a bolt-in swap as its basically the same car, only with a 1JZGTE.

Mmmmmm bolt in. What year model is the JZX81? What about wiring it up, cause I don't want to loose the cruise, etc and obviously I want the speedo and tacho to be reading correctly.
Note I don't want aftermarket ECU I want to use factory ECU from the JZX81 or whichever.
What about g/box? Can the std auto box be used/bolted up initially? Or will this crap itself straight away? Will it even bolt up?

Its a front-cut, basically you could swap over everything from the cut into the car. There are a couple of things that'd need doing, do a search for it, its been covered numerous times.

Tank capacity is 60Lt, not 70Lt. (Revise figures accordingly).

Well that makes a difference sounds more realistic as well.
Where can I find more info on the 7M/1JZ engines turbo and non-turbo?
How much power can be had from the factory 7M engine? Or is not worth spending money on it?

with reagrds to the economy figures i quoted, the 400-450km's is when the needle is pretty much empty, BUT before the warning light comes on. so i am guessing around a 50litre fill up.
the 7M-GE motor produces 142kw, and the 7M-GTE produces, from memroy, 179kw's. the 1JZ-GTE i think is just over 200kw's

Not much point asking me, as I ditched mine within 2 weeks of buying it in order to fit the 1UZ...

If you are talking MX83, this is incorrect...The manual states capacity as 60Lt. Empirical data (ie. me running our tank to practically dry!) confirms that a "dry" fill nets 60 Litres.
(Of course, if you are intimating that, at the empty mark, there is approx. 10lt left, then I retract my "correction"... )

What the ?
Yeah the 1UZ seems to make sense. 1/2 cuts are cheap, they make great power and that's w/out s/c'ing.
However, there seems to be g/box and wiring issues?

You could refer to ours as a lot of things; cheap, unfortunately isn't one of them.
We didn't go the half-cut route, instead buying an engine/gearbox combo, and running a combination of Autronic engine management for the 1UZ and 7M/AT ECU to control the transmission.
Still, this has been re-iterated ad-nauseum here; if you want an idea of how/why things were done, look at the web-site, which details all this and more...

I've been to the website that's where I got my original idea of buying a Cressida. So credit over to you
Did you go Autronic for making mods and additional power or won't the factory ECU wire up properly?
How difficult was fitting the engine in? Looks quite a tight fit
How is the fuel economy of the V8?

Autronic is *insert appropriate term here* easier to wire up than the factory stuff...Not that I did all mine; I had help, but I did do some of it such as injectors and mounting/wiring the ignitors.
Additionally, the "lure" of doing things down the track without the limitations inherent in the use of the OEM AFM (such as a twin or individual throttle body setup) was altogether too hard to resist.
I may never do these things, but then again I might...(Read my sig.)
Engine is quite tight...I am looking at fitting extractors at some point and have a bloke lined up to have a look at it. He likes a challenge, apparently, and this is just as well, as he's going to get one when he attempts squeezing them in this car! 
Having said that, it's come together OK. I've actually had some people say it looks almost factory in there, which goes to show that it's on the right track.
Fuel economy is as you'd expect around town for a 1500+kg V8 auto. Highway driving is quite good - I'd expect 600kms from a tank at a steady 110-130KPH.

Oh ok I think the 1JZ seems a better option for me anyway. So Toy ECU's are easy to modify like Nissan ones then?
