Are there many 1UZ-FE MA70's out there?

Hello again. I'm still deciding on wether I want a 1JZ or a 7M-GTE to rebuild and swap in... for the moment, still N/a and automatic..

But while researching a bit, I noticed in some "Engine Specs" page, that the Lexus SC400/LS400 1UZ-FE has actually more HP and more TQ than a 7M-GTE! Nice! ... I've also read in a few different places that the engine is even considered "over-engineered", with 38 valves and some other stuff they said... Most people talking about it, seem to think it's a pretty well built engine. The first site I saw was 1uzfe.com ... but that guy is putting one of these engines in an old 72 Corolla, sounds like a drag car maybe, not what I want.

So I searched more, and found a site about a MK3 with one of these engines. I :this, http://v8supra.com ... THe owner said he had a 7M-GTE which blew, and converted to 1UZ-FE. Although he speaks highly of the engine (once again, saying how it has an almost square bore:stroke ratio, etc, etc, built to rev hard, etc, etc), I was a little disappointed to see it only put 150WKW. That's around 200WHP, right? :-( ... Well, that's probably what a stock 7M-GTE puts, right? ..

I've also read there's an australian company selling Bellhousings to use the R154 tranny with this engine. Good. (Forgot their name for now, but it's something with D... heh).

The idea of a "small" 4000cc Toyota V8 doesn't sound too bad. I bet it must have a nice dyno graph with the 5 speed tranny.

Have more members done this in here? If so, I'd like to read more on their swaps, results, etc. If someone could point me in the right direction, I'd be very grateful.

If it's an expensive engine, I might end up buying the 7M-GTE, rebuilding it and stay with that, though.. but this is just a thought that sounded cool, the V8.

There's atleast 1 that posts on SF and on Lextreme's forums ( http://lextreme.com/forums/ ). It looks pretty awesome. I'm not sure how much work it was to get it in there though.

And yeah, the 1UZ's can hold down alot of boost. If you get a chance, look at the internals of the 1uz, they are beefy.

I wish to do a TT setup 1u in my Silver MA70.

I want to do something so bad with my 87, and v8supra.com has helped me to decide hehe.

I actually in the process of do a 1uz swap in my car at the moment.

Its not really difficult to do as long as you have some basic fabrication skills.

Once the motor is in and running, then I will be figuring out what kind of room and where to install a pair of turbos on the engine bay.

Once the actual swap is in progress (gathering all the peices and making modification that I want but not needed at the moment), I will be photographing and doing a complete write-up on the swap to help out others that may decide to go this route. I am hoping to be doing the actual install some time next month.

The 1UZ is a very well engineered motor but the aftermarket support is not as well developed as say the 2JZ. Has alot of potential. Mine in a MkII won the smaller MkI-III Mod class at TX2K6. Lextreme.com is an excellent source of info. Bellhousing companies are Castlemaine Rod Shop and Dellows both in Australia or for the W58 Bullet Supercars. Nice thing is electronics are similar to 7MGTE that parts swap(ie MAFTPro). Wiring is easiest part of swap, exhaust work was the most challenging for me.

Great. Nice looking SUpra, btw, except for the rear wing :p 3-piece ftw :p

I was actually thinking of a N/A 1UZ, but everyone who wants it, wants to turbo it... that's a little bit too much. Just use the 7MGTE if you wanna power up your car with the turbo way... =)

I saw the picture of your car on page 31 of the March 2006 Turbo. Very nicely done.

N/A is nice, but like elhsupra stated, the aftermarket support is not really there (yet, anyways) and being a FE classification, big HP N/A's hard and expensive to do. I agree with your comment about using the 7M for turbo/power, but I also have also always been one to be different. You can look anywhere and find a turbo 7M supra, but how often do you look and see a twin turbo V8 Supra? The other thing is with the V8 turbo or non, the torque is there a lot sooner and makes for a far better street car being that torque is what really accelerates the car.

I love the 7M and the JZ motors, but big HP number 7M's and JZ's are really nothing more then dyno queens. I seen countless lower HP V8's spank higher HP 7M's and JZ's at the track and on the street.

Thanks!
I do agree with cjsupra90 about the torque. The throttle response is great, and yes supraturbo90, I love the sound:D.
There are some companies starting to come onboard for aftermarket support, but most are Australia/New Zealand based at the moment. For a TT setup custom would be required. But there are some that are making big HP and the torque. Flip through the lextreme website and you will see a few. A TT 1UZ in a ST185 Celica or a dragster with a 1UZ and 6/71 blower, etc.
Just make that first step and come over to the other side :evil2:

Hmm, I have a chassis sitting around with no engine and found a 1UZ for a reasonable price. What esle would I need and what could I expect to spend? Custom fab stuff is no problem to do. Would the 2UZ be any harder to fit?

Let's see
For a MkIII you'll want a 1UZ from a SC400 (rear sump) with as many accessories as possible (including ecu, ignitors, alt, ps pump, AFM, etc.)
Fab mounts and probably headers/exhaust.
Wiring is relatively easy as most come off the motor into a single loom straight to the ECU. Alt uses standard toyota round plug.
PS pump may require changing the fittings on the lines, I am not sure.
Motor comes auto only, so either get the tranny too or buy bellhousing/ flywheel kit to bolt to W58 or R154.
You will buy alot of little stuff in the process (ie radiator hoses, new belts, etc.)
I would recommend to avoid the 4.7L 2UZ, only because it is an iron block. 1UZ's and 3UZ's are aluminum. If you have a choice, I would recommend a 1UZ. You can get an early or later model 1UZ. Heads/ intake manifold flows a little better on the later 1UZ's and are pretty much interchangable with 2UZ/3UZ heads. But the early 1UZ's have more support for cams. Exhaust manifolds are pretty well interchangable across all 1/2/3UZ's but kinda moot point if your making your own.
Price range, the early 1UZ's are always the cheapest. I try to post some more when I get off work:icon_mrgr

If I'm reading the dyno graph right from the Turbo issue on Eric's NA it made 225 rwhp and about 240 rwtq.

HUH, that's nice for a stock, but it doesn't touch : 637rwhp/574rwtq @ 29 psi.:evil2:
