You'd expect bores like that in a V12. They are a very long lived engine but most don't make it to old age for reasons of neglect. Those connecting rods and crank are going to be fine to about 700 - 900hp. The crank is already probably forged, the rods are definitely forged. Thing is V12s are have such a large overlap in firing cycles that there is almost no torsional vibration. In fact V12s have perfect balance - primary and secondary. I'm a Jaguar V12 nut and this engine is better designed than any V12 Jaguar. Added to the the buttressed or skirted block has 6 bolt mains - 6 bolt mains. How many? 6 bolt mains... All those mains all with 6 bolts and a V12 make the bottom end intrinsically rugged. The stock crank will be fine. If you intend to turbo it up I'd do this, take the existing rings off and increase the gaps and put them back in. If not put it all back together with new bearings and the old rings. NA the only way to get big power out of it is to rev it up. There's no other way because it is only 5 litres. The place to get power out of this relatively cheaply is the the camshafts, valve springs and an injection system that has native 12 cylinder support with native 12 cylinder ignition support. This is where the big expense will be. There is a place in New Zealand that sells reground stock camshafts. I'd look them up. They're on TH-cam. Realistically you're probably only going to get 450hp tops out of this engine by keeping the rpms below 7000rpm using stock components. All V12 Jaguars turn 6500rpm no problems at all and this is more rugged than they are, so 7000rpm on this will be doable. That's still not bad in a 260Z though is it? Also a V12 is 2x inline 6 engines joined into a Vee configuration. Each bank has the 6 cylinder firing order of 1,5,3,6,2,4.
I think you just won best comment on my channel! Thanks for the write up, I appreciate it. I found out Toyota forged the crankshaft from the factory so no worries there, I have a company in California grinding the cams right now. I have two turbos already to be put in! The forged rods are here already, and the forged JE pistons are ordered too! I also snagged ARP main and head studs for the engine, new valve seals and a bunch of other stuff. If you are interested in watching the newer videos a bit of progress has been made, I’ve learned a good deal since I made this video, and love reading more comments like yours, there’s always something to learn.

Haha wow! That’s one heck of a swap. Hopefully you have the room you need. Find me on Instagram and message me any questions you have. I would love to help.
good this video exists becaus i ripped mine apart in 2 hours to the last main bearring XD i wont reuse anything so thats why i threw most of it away but its a good brainstorming thing for the coolant lines
Engine looks really clean inside. The huge oil filter is the same from the 2H diesel engine in the Landcruiser from the 80's. Easy to get here in Australia where those were popular - though not sure on your side of the world. Part number is 15601-68010. Cost me 20 bucks. As for the valve covers they seem to be made of a magnesium alloy. I had mine glass bead-blasted prior to painting and noticed they came up very dull (I think because they have Zinc in the alloy as well) once stripped back to bare metal unlike all the other intake and engine bits I had cleaned which are all normal Ali alloy. The magnesium might be a little challenging for welding repairs on the covers. I have since learned that Toyota have made a few engines with magnesium valve covers.
I do wanna have that engine on my dream car. got the design on paper. plus with a twin turbo setup that can get 500hp or more with proper tuning and modefication plus the sound it can makes is similar to a classic 60s F1 that is very rewarding to be honest
The stock connecting rods are very poor quality, they will break before 500 horsepower, but if you switch them out and build the engine 500 is very easy to get to
love them i hope to get stared on one soon been on back burner way too lonng that crank is a forged unit like most all good Toyota Japan made engines thats called over thinking it way to much on my v12 build ill be regrinding camshafts and may ceramic coating piston at home the tops arp rod bolts and ring gap thats it as ill only be using pump gas and lower boost i may do forged after market rods to as they are a bit small but they are forged but small . truth is all it or most any engine needs is a good tune and ring gap set and to be clean camshaft regrinding is the next thing
Hey There, I was in the process of doing the same thing. Did you find out on how to do the motor mounts or electrical connections? How did the engine fit, was it snug
one last question, just need your opinion. i wish to put this in a heavy van. the engine it has only a 1/3 of the horse power and a 1/3 of the tourqe of the toyota v12. The v12 would not struggle with the van would it?
A bit of a NuT here love old Toyota`s /Z car i own both ;] i need to know what is my option for a flywheel (manual)for 1gz ???? Nice build is weight known.. hi from east TN..Sounds like diy swamp / evaporative cooler look at green house builds work great in l;ow humid areas man..yep those factory forged rods are a bit small those Toyota oem cranks are forged look at parting line is the way to tell wide vs thin parting /casting lines ..i am cryogenic freezing (finishes the Harding processes ) my oem 5mge forged rods they are fairly big all ready so with that be all ill need arp bolts to add reliability...pardon grammar i edited this post a few times i just got up from my slumber :]
The 1UZ clutches and flywheels fit this engine from what I have read. Weight is 600 lbs (272 kg) with all the accessories and fluids, plus bell housing.
My goal is to buy a 2jzgte 1gzfe s85 and ls3 and build all 4 of them. I just wanna have the flex of owning a i6 v8 v10 and v12. If I could I'd buy the 1lr-gue over the s85 but that would be expensive asf and leave an lfa in the trash
Wow this is becoming my fav engine! look at these 6 bolt crank bearing caps! Is it a 60 degree V? it looks pretty narrow! beauty of a 12 its perfectly balanced at any V angle! how much boost and power can these things safely take with stock internals?
Thanks! They are great engines. It’s somewhat unknown still, there aren’t too many people pushing these hard. Some people have reported failures around 500 horsepower I believe? I would upgrade the rods and pistons at least, they are fairly weak components.
It was roughly 25 inches in all directions, but that’s only rough. I don’t have the engine on hand to double check and can’t find it written down anywhere.
So cool man. I bet a billet crank will be some serious money haha but seriously cool. How did you get this engine? I think the car they come out of was only available in japan
I started looking at getting one made, turns out Toyota made these crankshafts forged from the factory. So no point in getting one billet, as it will be strong enough for what I’m planning on doing. Yes you are correct, they come out of the Toyota century in Japan. I had to import one through California, there are a few companies who sell them if you’re interested.
Did you put the screw in to the split scissor gears on the camshafts? If not you're going to have a bad time if you reassemble and it'll sound it's spat shims
I plan to rework the head, cleaning everything up, have the surfaces machined, obviously gaskets, maybe regrind the valves etc. It's probably all going to be pulled apart. Making sure it was all aligned was what I was hoping my friend Vern would be able to help me with. I’m not an engine mechanic, so I’m not sure I did it properly.
@@rustbucketbeauties2767 just make sure the adjoining cam gears get reset when you reassemble. The heads don't need much in terms of porting for performance, minor work around the valve guides and they'll flow enough for 1k wheel
@@rustbucketbeauties2767 yes, I'm doing a TT swap. Have had the engine for a number of years and have done extensive r&d on the engine and components itself
The guys from quick shift.tv in Australia are working on some steel head gaskets. They are going to make a small/limited production run sometime this year. Other than that I need to source pretty much everything for the engine still. I didn’t plan on tearing the engine down last week, the connecting rod manufacturer needed one to reference so I started on the engine side of things earlier than I planned.
Hey I am theorizing if I can squish one of these in my 2012 is250. Do you think you might be able to help me out and do some measurements of the engine for me?
The engine is being fully built right now, so it’s at the machine shop. My engine bay however is roughly 30 inches tall and wide. I think the engine itself was pretty much a 28 inch box. I can get you some better numbers later but that’s off the top of my head
