1962 MG MGA Conversion "Mater"

Hi all,

OK, I'm actually researching this for another car, though I'd love to see one in an MG.

What do you guys know about the Toyota 1UZ-FE V8 engine found in the Lexus LS 400. I've been reading a lot about it and apparently it loves to rev, puts out a good amount of power, is reliable, and is much cheaper than the LS1.

Does anyone know anything about this engine? If anyone has experience with it I'd love to hear it.

Thanks,

Darian

I was going to use one but found the width with the 4 cams a problem in fact the steering column comes out right where the head is. They are so much wider than anything else and decided that the only solution would be to cut the car in half and make it wider in the body which I was not prepared to do. It is a pity as they are so cheap in Aust, I put one in my son's 87 supra with a 5 speed and it is a brilliant car

Brillant engine. Manual trsansmission rare in US. Engine management can be tricky. As you noted, it is a bit wide.
Miata crowd has sniffed it our for a while but never caught on.

That would explain the difficulty in finding them with a manual tranny then..eh?! I am guessing someone in the aftermarket has stepped up to this plate them?

And that in a nutshell is why it will not be seen as a popular swap option. The machine shop work alone will eliminate most candidates and the mix and match custom components make for a maintenance nightmare for any future owners.

Buick/Rovers, 302 fords and even GM V6s and V8s can all be dropped in with off the shelf parts that you are confident will be available for the foreseeable future.

Best bets are combining with an R154 trans. I think there are some folks making adapters. Good for the unique factor, but for simplicity of a build, ease of parts and raw power, the LSx stuff is pretty hard to beat.

The 4 litre Lexus engine was only available with an auto from the factory but some places like Dellow build conversion kits for them using the Supra gearbox in most cases.

The engine itself measures a neat 700 mm in all three dimensions and is all alloy so the weight should be a step in the right direction too.

The engine management system is an essential part of the package and if you don't carry that over the engine will run delivering less than the power and torque levels in the Lexus.

I seen a good article of one in swapped into I think a corolla for autocrossing, but can't remember how I found it. But I found there is a site dedicated to this engine, and swapping it into other applications. Here's an article on that site with lots of info, the author makes an adapter plate to mate it to the Supra 5-speed for $250, and details all parts and machining required to do it.

Edit, I found the article, it was in Grassroots Motorsports.

Hi Bill,

Still here lurking around. I've never done the Toyota UZ conversion, I went with the Toyota 3.0 2JZGE (I-6) instead. I considered the swap after I pulled out the Rover, since the UZs are in abundant here in Thailand but as Barry said, the engine is too wide. The twin cam set up just makes everything square, just won't fit. Not in an MG anyway.

Here in Thailand, many Range Rovers had their motors swapped out for the 1UZ/ 2UZ, the irony...

We are always interested! It is wide, but length and height look good. I would also like to see more pics of the RV8 front suspension.

Yep, what those guys said.

We've talked about this swap a little. I've even been waiting on parts and a chance to do a test fit in the spare parts car, but no current intentions to do the swap. So some details would be nice, such as year, donor, etc. What pan, what exhaust, what engine controller, what you have to do to make the electronics work, motor mount choice, and stuff like that. And pictures. Definitely more pictures. This is certainly one that you should submit a How-It-Was-Done to BritishV8.org and I'm glad to see someone has grabbed the bull by the horns. Best of luck with this swap and we are here to help. I understand from the TR7 guys that it makes for a tremendously good car.

A brief outline of the conversion so far.

1980 MGB GT purchased as a one owner car. My wife used it as a daily driver for approx 18 months then it was into the shed for a quick repower then going to be back on the road and resored as we used it.

I ended up buying a Toyota Supra for my wife to use and decided to do up the MG completely.

I have fitted a Toyota Hiace diff, shorted on one side by 50mm to allow the tunnel to line up, with a Hilux LSD diff head.

The motor is a 1uz-fe 4 litre quad cam Toyota motor driving into a Automatic bell housing with a hydroloic thrust bearing. This means that I dont have to try and fit a clutch slave cylinder into the tunnel.

I have an adapter plate fitting a Toyota W58 (Supra) 5 speed gearbox.

This means there is all Toyota running gear.

I made my own front hubs so I can run 5 stud with the face machined 12mm inboard allowing me to fit the brake disk over the studs instead of bolting it to the back of the hubs. I have Mazda RX7 disk brakes front and rear. This gives me a cable handbrake that works directly on the disk.

The engine management is a Link Computer. Check out http://www.linkecu.com/

The build is slow due to time and money but I will have it running and take it down to the track for a test run shortly.



Cheers

Colin
