Cressida to 1uz-fe swap
|

In regards to converting an MX83 cressida to 1UZ-FE power, can anyone confirm that the best donor car would be the uzs131 toyota crown? I have heard that the exhaust manifolds on these cars are more compact and therefore more suited to this kind of swap.
Any info much appreciated.

Hmmm...Where to start?
Yes, the Crown engine comes with "smaller" (read very restrictive) manifolds. It also mounts differently in OEM config (a tilt, if I remember correctly), runs a remote oil-filter (handy in an '83 application - trust me, I know)!
It also runs a clutch fan and, I'm told, puts out less power than, say, a UZZxx Soarer engine, primarily, due to the exhaust manifolds.
Oh, and it also uses two separate ECUs, 1 for the engine, 1 for the transmission. (As distinct from the Soarer, for example, which uses one ECU for both)
Being a Toyota engine, I'd imagine there are a number of other variations also...someone who is more familiar with the Crown engine will probably expand on this.
BTW. My project is using the Soarer engine and, yes, the exhaust manifolds have had to be "re-jigged" slightly to make the whole thing fit, particularly around the steering input-shaft...

man i imagine its a cool and different conversion an looks exelent like v8cressida's but from a conversion point of veiw i'd say realy consider the J it's a piss easy conversion which can be done over a weekend with the correct equipment...we lifted the chasers body straight off the engine/crossmember/ suspention/steering (we left everything in one peice even left tyres on for better manuvourability  ) lifted the cressida up really high and slid everything under and bolted everything straight up....it was just to dam easy to consider anything else unless you really really have your heart set on the the v8 up 2 you man and good luck with what you choose the cressida does rise to the occasion and feels great with some grunt under the hood

Thanks for the input guys.
I have still got my heart set on the 1uz swap, as i cant justify the apparent fuel consumption of the 1j as the car will be a daily driver and am trying to keep the conversion and the future running costs to a bare minimum (not to mention simplicity of engine setup,and possible insurance hassles).
As yet I haven't done that much research on the 1uz variants because i cant find that much info on them in regards to the specs of the sump,manifold,wiring, and dimensions.
I just don't want to get burnt by buying the wrong style of motor.
Also, Biased I was under the impression that soarers didn't come in a front sump config? How do you intend to 'rejigg' your exhaust manifolds, as they are cast iron arent they? I thought that cast iron could not be bent, welded etc.(not having seen the manifolds in the flesh before, i would be very interested for you to tell me how you plan to do this).
Sorry for asking so many questions, but i really need to find out as much as i can from some people in the know before i go out and buy one of these engine/trans combos.

They are expensive, but how do you think these would fit in a Cressida?

1UZ that I have seen have tubular steel manifolds.
Stainless, I guess, Cut and weld.

Soarer engines do, indeed, come in front sump application. Also, the manifolds are tubular steel and, thus, are "cuttable" and weldable.
Some other points of note re: Soarer engine (Having owned a Soarer and now, the engine from one, I can comment...
They run a hydraulic fan, so often you will get the engine with a remote reservoir for the fluid.
The manifolds are tubular but are "configured" differently each side...mine had to be cut and re-shaped on RHS to clear steering input shaft, and lengthened at the flange LHS (to match up).
They normally have "V8 Quad-Cam 32" on the lead covers, whereas the Crown engines I've seen have "Toyota" there and the reference to the V8 etc on the plenum "id" plate. The Crowns also run a clutch fan...
So, in short, for what you are doing, a Soarer engine will be fine. Make sure that you ask for an engine from a UZZ30 or 31 Soarer (NOT UZZ32, as it runs a separate pump/ancillary belt arrangement for the 4WS setup, something you wont need in an MX83 )
Hope this helps.

I was always told the Soarer 1UZFE's were mid-sump, because I was going to be needing a front-sump when I want to put the 1UZ in the Supra...
Are you 100% totally sure?

Unless another of the 1UZs came with the hydraulic fan (Unlikely, as the Crown definitely came with a clutch fan and the Celsior came with a thermo), and, unless another of the 1UZs came with an "angled straight down" oil filter (Crown used a remote filter and the Celsior came with one which angled towards the front of the engine), then yes, I'm sure I got a Soarer engine and it is definitely front sump...It's gone pretty much straight onto the existing cross-member.
If anyone has (quantifiable) info to the contrary, I'm all ears.

Well what do you know, if a Soarer has a front sump, then that makes it so much easier to find. I know someone who has one for sale for $2200

Firstly, get them to actually check...That's what I did with the bloke who sold me mine!
Secondly, $2200 for what? Engine? Engine/Gearbox?
Depending on what actually comes with the deal, it may pay to shop around...I got my engine and transmission for $1500, delivered from Brisbane.

Well that makes things alot simpler if i can get a soarer motor, and mod the manifolds to suit.
Biased99, you say that the mounts nearly lined up close but which mounts are these? are they the 7m or 1uz ones?
Me thinks I'll have to go off to a import wrecker and take notes on the variations of these motors.
Also out of interest, and seeing that the crowns and the soarers have different manifolds, can the same be said for the celsior/ ls400 ie, the manifolds are the same as the soarer or are they different again?
