1GZ-FE - My new project motor!

[redrocco]

As far as weight I had read some place online that the 1GZ is very close in weight to a 2jz-gte but untill I can get mine on a scale I don't have a true number. However after removeing all the parts that I do not need I would guess I will see at least a 30% reduction. As far as money goes I am trying to do this for as little as posable but I will NOT cut corners. I do my own fabrication which saves me lots of money and I will also try to sell all my uneeded parts to get back some of the cost of the engine. I will also be offering copys of parts I make for sale to people on this fourm as well as lextreme. For instance the billet 4140 tilton triple plate flywheel I am makeing for this swap will also work on a 1UZ as the crank snouts are the same. If I make 2 flywheels for myself and 4 or 5 extra and sell them for $150 - $200 the extra flywheels will pay for the rest of my clutch and not cost me anything out of pocket. Not trying to get rich just don't want to go broke. ; )

Stuffing a v12 into a Mk3 Supra, and you don't want to go broke? :rofl:

Good luck with that sir.

Definitely looking forward to seeing the results. Subscribed

I'd love to hear one of these built up in NA form. 15:1 CR (run E85), custom cams (maybe JZ cams could fit?), head work, ITBs, and some well designed tubular manifolds. I'd bet 450whp could be attainable pretty easily, if not 500whp. I'm not sure what the stock rev limit is, or what the limiting factor there would be (rods, valvetrain, or what), but an 8000 rpm rev limit would sound sweet. Doing custom rods/pistons would mean you could play with improving the rod ratio too.

Oh the ideas.... I love projects like this, good luck.

One of these engines needs to go into a 635CSI.

Subscribed for sure. I'm looking to go down this path too so I wait for your solution to issues with bated breath. Best of luck!

I have been working on getting the engine cleaned up over the last week or two and its starting to look nice. I have also found a very nice 89 MK3 shell about 5 hours away from me that I will be picking up on 3/24. After talking with some other 1GZ owners and reading posts on lextreme the 1GZ rods seam to be 10% to 15% beefier then the week 1uz rods. The week 1uz rods are good to 50HP each reliably so the 1GZ rods should be good for 50-60 HP each so 600HP to 720HP should be fine on the stock rods as there are 12 of them.

Love it.

you sir, are a genius i just want to hear what it sounds like. very cool project btw, v12 vvt-i and boost = pure bliss. adding nitrous for further excitement?

 

[supranz]

Bit of an odd question, but did you get the accessories with the motor? I see you have the powersteer pump, but what alternator and A/C pump are you going to run? 7m ones with custom brackets?

 

[redrocco]

The engine came with all the accessories but I will only be using the alt and the PS pump. I will not need the ac pump or the hydro fan pump. I will how ever need to add a dry sump pump. I am also considering swapping out the belt driven water pump for a remote external electric unit as the water pump and thermostat housing are quite tall and mounted on the very front of the engine were there is the least amount of hood clearance. I will know more once the engine gets test fit and I see how much clearance there is.

One question - how the hell did you source it, and how much did it set you back?!

x2. In all my searching/shopping, I've never seen a Toyota engine bigger than a 6 cylinder...

The 2uz-fe is quite common.

Well this is just two 1JZs

This:

Somebody imported that car?(was he dealing) ...and how much did it set you back?!

Also, you said it was 6 bolts mains? Some trough the side?

UZ guy tought they were cool... Back to the drawing board !

Frain bart... completely forgot the volume engines used in pretty much every luxury car Toyota built for 15 years... 1uz just as common too. However, they only used this engine in one car.

Well this is just two 1JZs

Displacement wise, but I don't think it really shares much of anything else... I believe the OP posted the bore/stroke details earlier.

Toyota has been making V8's since 1963 and also has made a V10 and V12. I had been looking for and researching the 1GZ for the last few years. After I finished my 1UZ swap I started looking into getting the V12. Took me over two years to find one for a good price. I eventually got lucky and found some one with one for sale 3 hours from my house for $3200. It has the same 6 bolt main setup as the 1uz, 4 bolts up from the bottom and 1 through each side. Lots of the design for the 1GZ V12 came from the 1UZ, they can even use the same flywheel. The 1UZ can be had for $600 or less and makes for a good engine and also good practice for the V12.

It's more like a neo aluminum block vvti 1J, per cylinder bank.. but it really shares zero in common as far as what I can tell.

Toyota needs to follow BMWs way and make a sleeved aluminum block 3.5L, turbo I6 (3JZ).
