 Whats the deal with 1GZFE
|
Mon, 02 September 2002 07:24

Ok guys, I need the low-down on the 1GZFE.
Basically, I've got it down to this:
5l Quad-Cam 48 valve V12 with "206kW".
I'd be guessing it'd be constructed along similar engineering scrutiny that made the 1UZFE as good as it is.
Anyone know what its "real" power output is? Any other stats, ie. injector sizes? Any ideas on the dimensions on the thing? This isn't for me, someone I know is interested in finding one for a kick arse project!
BTW, does anyone know which importers actually import them?
Thanks,
Nathan

As with most of the "upper-end" Jap engines, the 206KW figure refers to the gentlemans' agreement the Japanese manufacturers have...the actual power output would be speculation and nothing more, although I'd be very suprised if it wasn't way in excess of the quoted figure. (That is, unless they've detuned it to buggery!!)
From the little I've read (and, believe me, there IS precious little to read!) they are engineered along similar lines to the 1UZ,(although they do not look alike - the 1GZ looks considerably larger!)
As for a project, I'd suggest that there would be very little here that you'd squeeze one into, although I wouldn't write it off arbitrarily.
Your biggest problems will be these:
1) You will struggle to find one. Anywhere. They only came in the '97-on Century Crown, of which there are precious few. I don't believe that there is one in Australia (but I could be wrong!)
2) You will probably be able to obtain parts (through OldMac Toyota or similar), but you will need the full model and frame numbers of the donor car - in other words, get a half-cut, if you can find one. Oh, and the parts will be VERY expensive.
It sounds like an excellent project, if your friend can make it work...

an educated guess would be in the vicintity of 330-370bhp .... decent for a n/a, but realistically you'd be better off with a 2jz-gte

depends what your after. Hes after an awesome NA engine. He doesn't want a 1JZ or a 2JZ.

Hi I'm no genius, but I was thinking of installing this engine into my supra. Alternatively, I was going to get a 1UZ stuff it in & later supercharge(or supracharge  ) it.
Which would result in a better performance beast???

From what ive seen... The 1GZFE is not based on the 1UZ at all..
Its a 60 degree engine unlike the 1uzfe which is 90 degrees...
Its bore and stroke are not similar to any of the UZ series engines either...
Muck of its percieved width is from the inlet manifolds which sort of go over the rocker covers and then go back inwards.
I do belive it is a 6 bolt mains however,,,
For similarities I would start to look at toyotas 60 degrees v6's such as the 1MZFE etc which in my opinion is a much closer match to the 1GZFE

knew a guy who knew a guy who had one.... hehe
anyhow, halfcut was had for 20 something odd $k's... very very pricey...
engine wise, it's spectacular with huge potential....
6 bolt mains, undersquare, vvti, v12.... you can fit one in a supra without too much trouble due to the 60 degree V....
and imagine a turbo on each side.....

$20k for a front cut is pretty steep... I know of an engine/gearbox package which sold for $1500 in Japan. These things are very rare though, that's the only one I've ever heard of for sale.

These things are rare.
If your mate is not worried about brand, you'd probably be better off trying to find a BMW 5.0 V12 instead from the 850i.
A lot more of these were made (in Europe though), although parts prices would be up there too.

Apparently you can order an engine package from Toyota Japan for a measly $25k AUS.

*Kicks Norbie* Then why the hell did you do the 2JZ conversion then?
I wish someone actully got hold of the engine (not possible with me as I am a young Uni Student  ) as myth would be put to rest.

lloking at the torque figures i'd be guessing at about 240-270kw. Depends on the nature of the enigne though ie rev happy high hp output or lazy engine aka old holden v8 with fat torque curve.

The engine was built to be lazy, smooth and torquey. It is fitted in a huge luxo-barge after all.

That said, like the late model 1UZ's, they can be both lazy and torquey and f'ing powerful all in one. Beauty of variable length inlets and infinitely variable valve timing.

good luck with the wiring, the car it comes in runs countless different control ecus, the engine alone has one ecu for each bank of cylinders, then would come the auto ecu which would be infinately linked to the main ecus, you would have to have a very good half cut and then a wiring genius and heaps of cash, or order a top of the line motec and borrow one of aussies best tuners to even have a chance at getting it to run well.
This motor is not ever going to be a realistic option, it is the 'one that got away' story of the toyota modifiers world. no matter how many threads pertain to it and brag of intentions of a crazy conversions, just like an urban myth, it fades into the background untill the next time someone knows someone who knows someone who has met someone who can get one from japan, or is going to find one whatever it takes.
not meaning to be cynical, but if you or your mate can get one ill give you a full set of flares and guards for your supra, ( and dont say you dont love them, denial is futile  )
good luck

FWIW they do have a 6-bolt bottom end. Just been reading the workshop manual I got for one.

do you have a 1GZ in your garage?
if not, the 1UZ will be better, as it actually 'exists' and you can buy them easily

Agreed. No-one here has seen a 1GZ, much less modified one, so your question cannot be answered. Get the 1UZ.

Holy mother of god is that some complicated inlet piping !!!!!
Strip the crap out of it, remove the plenum and make your own and it would look nice .....

Two dual-entry plenums hanging on either side of the engine, it's not that bad! Would make it easy to set up quad throttles though.

Forget the look of the intake, just look at that TORQUE 
I have various parts of my anatomy, that I would gladly trade for that engine.
