Project Scraper UZX73

Some pics of my car from a local meet last night

Just a heads up, but I think the MKIV rad is the better choice now. The diameter of inlet and outlet tubes for the LS400 rad is 1.5", but it's 1.38" for the Cressida. The MKIV is the best size available at 1.4" diameter for the inlet and outlet. That means coolant flow will be unimpeded and as close to stock for the 1UZ in an LS400.

Cool thanks for the heads up! I'll get on that soon.

Really?? You got a BHG on the 1UZ??

I'm not 100% about it yet but it is looking like it. I need to do a compression test to be sure. Results to come soon.

So how hard and expensive was the swap? Are you happy with the 1UZFE?

Overall I'd say it was no more difficult than any other swap. If anything it was easier than a turbo motor since there's no dealing with intercoolers and pipes. I'm very happy with it. I spent around $1200 on the swap overall. The only negative about the 1uz is there are very limited aftermarket parts. When you want more power you're either SOL or it's going to cost you big money.

I thought those W58 adapter kits were expensive. You must have got a good deal on the wrecked donor car. Did you get all the accessories to work: pwr steering, AC? How long did it take to do the wiring? Did you have to get a custom exhaust manifold or header made? Sorry for all the questions but I don't think many people have made this swap into an MX73 and details are hard to come by.

Yeah got the full car for $300 and then scrapped it when I was done. Power steering works. AC will work as soon as I get a line replaced and charged. There's one small modification you have to do to the driver side header to clear the steering linkage. My buddy did the wiring in about a week I'd say. No worries keep the questions coming

Thanks. All the extra horses must feel nice. Lots of these engines in the yards around here but that's a crap shoot I'm sure. Somebody in the old forum had a a beautiful 1UZFE in a build thread in a MX83 That was supercharged and maybe blown too but he put ridiculous amounts of $ into the engine. I think he was running 12 second 1/4 miles. Access to anything on the sides of the engine must be super tight. My arm gets stuck for a moment with a straight six sometimes.

Pretty sure I've seen that one. I'd love a blower or turbo on mine. First things first though I have to fix the head gasket issue. No fun.
It's pretty cramped for sure but I have access to any of the components that would ever need to be changed. Spark plugs aren't hidden or anything.

I think that guy was getting 380 something HP out of his engine. Not sure if that was rear wheel or crank. I seem to remember him saying he had 6 or 8k into the motor alone though.

380 seems terribly low for dumping 8k into your motor lol. At that point I'd just stick with a JZ motor.

It was beautiful they he had it set up. Lots of chrome. But you're right as far as power for that much $ you could get a turbo JZ up to it's true potential I would think. I remember reading somewhere that with proper tuning a JZ could crank out in the 700 HP range which would be sick. At that point I would think you'd be able to blow away pretty much anything on the road and they wouldn't know what hit them if it was in a Cressida.

I've pulled the 1UZ and transmission out of my donor LS400 a couple days ago. I was looking at tranny and realized it does not have a mechanical speed sensor like the W58 does. What did you do to convert the speed sensor from mechanical to electrical so the ECU and LS400 gauge cluster get the reading??

Mine isn't hooked up at the moment. But take the electrical speed sensor out of the LS400 tranny and hook it up to the w58. Then run the wires wherever they need to go.

^I wouldn't recommend that. i would def. relay on solid if you're looking to do anything serious. poly bushing are going to wear out if you're beating on the car a lot.

Patience is a virtue... don't just settle for rubber when people offer nice metal ones...

MY old shop has a hefty amount in the owners 2jzgte pushing 900+RWHP currently

Yeah I didn't want to say anything about the 2jz power lol. If my Genesis is ever done I'm aiming to get around 600whp and don't expect any problems.
Anyway in cressida news, cometic head gaskets came and I just ordered a new grill you might like

I'm Hating you so hard rite now....... 0.o*

How do you like the 1uz? What did you need to mate it to the w58? The stock 1UZ bellhousing? if you could do it again would you do a 2jz swap? Thanks. Great car man. Very inspiring.   

Sorry for not being active here. If I could do it again I'd pick the 1uz but go with the vvti motor. Swap in the early rods and slap a turbo on it.
The car is currently waiting on a few parts before I start my Z33 transmission swap.

So finally received all my parts. Updates coming very soon. The transmission test fit/mutilation is currently underway
