Default Toyota V12 in 99 Legacy sedan.

This car was originally going to receive a twin turbo Nissan VQ30 V6 that I had built a heap of custom stuff for and fitted into an E30 BMW. I needed some cash for my 2JZ 1968 Toyota Crown body restoration so sold the TT V6 stuff to a mate for his Legacy.
This is the V6 setup.



So I rolled it into the home shed and started pulling the melted subaru engine out. Dropped it completely out on saturday and dropped the Vq in but it wouldn't fit because it is the tallest engine ever built. I cut the sump and it still wouldn't fit. I cut the eyeballs out of the Xmember and it still wouldn't fit under the bonnet, like by about 100mm. I put it down to the way subaru have built there Xmember. It seems they built it to fit subaru engines rather than nissan V6's.

I thought I'd throw my Toyota V12 in there for laughs and it fitted better than the stupid V6. So then I rang the owner of the car and told him he needed a V12 instead and he said whatever, as long as it does skids.

After a bit of trial and error we figured out a Xmember/rack mounting modification that would have the least impact on steering geometry and allow the engine to fit.


Proof that the bonnet shuts.



Proof that it opens.



Acres of space in there, the std headers will even fit with a bit of fettling.







Bellhousing is enroute from Japan and will be mated to a TR6060 6MT from an LS1.
The engine will be run by a Vipec V88 or Haltech PS2000, which ever the owner wants. The manifolds will be modified to accept a pair of ford throttle bodies. I will use an electric water pump to simplify the bulky thermostat region. Will whack an R180 sti 3.545 diff and shafts in the back and see how they cope, if they fail I have an S14 rear end that is pretty easy to adapt to the Gen 3 Legacy rear suspension.

Is it the 1GZ-FE out of the 2nd generation Century? I'm a little rusty with my Toyota engines.

That's quite a build! I find it funny that the eg33 needs so much more fab-work then the V12. :/

Im amazed at the general lack of replies about a modern lightweight'ish car with a brilliant chassis and suspension design and a 5L V12.

Do go on JZK25

I had no idea Toyota even made a V-12; learn something new every day!

Very cool build, please keep us updated.

It may be double the weight, but it will outperform an EJ by leaps and bounds any day of the week, and dependably too.

The V12 is all alloy and not particularly heavy or physically large. It also doesn't position the weight any further forward than a subaru drivetrain. Overall there will be a slight increase in drivetrain weight but it will still be distributed the same way.

I had no idea Toyota made a V12! By the way Delta Current Controls makes a variable speed radiator fan/electric water pump controller that speeds up both as heat increases. Might be a really cool way to control those two things on this engine. You may have to email them, their website is being re-vamped right now.

TopSecret Japan twin turboed one of those engines and put it in a MKIV supra before. This should be interesting!

Rumour has it that there is two TD06 SL-20G's to be bolted on the front of this too

Top secrets had 900hp with two 300hp turbos, amazing.

It seems it will be getting TDO6's, the owner is a cashed up bogan, they love that sort of thing.

Did some work on the car this weekend. A boilermaker mate cut and folded a 3mm plate to fill in the gap in the X member that we cut out to clear the engine and I trimmed and welded it in yesterday and mounted the rack.



Std and modified crossmembers.





LH engine mount. Rubber mounts are diesel patrol.



RH engine mount.



Engine sitting on it's mounts. I haven't welded the mount brackets yet as I want to move the engine over to the right a bit more, this will require a smaller diameter booster off a different model subaru.

Changed the booster tonight, gave me a heap more room and the engine is now dead centre ready for a gearbox.





Starting to think about clutch master cylinders now.

Very nice! Do you have enough clearance for the steering column and coupling?
