Looking into fitting toyota engine into VH Commodore.

Allo,
I've sort of inherited my grandfathers old '82 VH Commodore and its in quite good condition body wise, only a little bit of surface rust in the c-pillar and some in the boot opening. 80,000 km on the clock on the original 6 cylinder engine. Only problem I'm having is.. its a Holden engine, not a Toyota 
Just wondering on opinions or ideas of swapping over to a 4 cylinder Toyota n/a powerplant of sorts. I really have no idea at this moment, just dont really like the thought of selling the car outright as it still holds sentimental value to me.
Has anyone on the forums done something similar and if so, was it easily swapped in? I'm assuming a few things would have to be custom made/fitted starting with engine mounts and mating up a suitable gearbox etc.. but being n/a still I cant see too many issues.
Any ideas would be appreciated, especially the scary prices and the likes.
Thanks,
|

Fairynuff. That's basically the sort of comments I'm after too.. if it wont work, I'll just work on tidying it up and making it run more smoothly and see where it goes from there.
Thanks.

why not just work the six there is thousands of parts around and plenty of mod parts for a holden engine. A toyota engine will end up costing you a mint with custom mounts etc and if you really desperate throw a 253, 308 or even an ecotec v6 plenty of parts round for them too and ppl are starting to get some serious numbers out of them.

there has been a few toyota to commodore conversions over the years, the one that I remeber best was a green VL? with a 1JZ with a bigger turbo.
As mentioned commonwhores are heavy but not significantly more than a cressida or supra. Id go a 2JZGTE or a 1UZFE perhaps with a turbo added later. Either engine will give you plenty of power and can easily be improved with carefull selection of turbos and ancillaries.
2J front cuts can be had from under $3K these days and 1UZ's are about the same if not cheaper.
realistically you could sell the car and buy a newer, comfier, faster better designed car easily for the money youd be spending. Personally I think you cant beat new technology these days and the only reason id play around with an older car is if it was going to be a thrash machine for offroad or rough events.

not 100% certain but I was told a while ago that VH's are around 1300kg. So that is actually lighter than a supra or cressida. I was going to put a 1jz into one before i got the rona.

Probably the cheapest way to make it move would be to put a nitro fed 350 chevy into it. You can get a worked 350 Chevy from various places which would make the Commodore move alright, and if you want to drag it, give it some laughing gas!

you could look at a 1uz - they would be lighter than any holden V8 and much smooother for more power too ..
CAstlemaine rod shop has some of the parts to get the bellhousing + such to suit a W series gearbox - and they probably have the mounts to get the same box under the commodore .
Outside of that - you could look at an Ecotec V6 from a later commodore + swap the running gear from that into the older shell

heaps of options for the old VH. believe me
the K frame from the VB to the VP is the same - so ;
1. VN - VY V6
2. RB30E/ET - or RB20DET?, 25, 26 also - 26 more work though.
3. 253/304/308 - done to death
4. 1/2JZ - not many of these around
5. 1UZFE - i've seen this done - weapon
6. SR20DET - just an idea
Plenty out there, but, don't think you'll get away with it for a couple of grand - just bear that in mind.

If you let me know your email address I can send you a complete article of fitting a 1JZGTE 5 speed into a VL. Nark is a bit slow adding it to the tech docs on line.
The only difference between it and the VH will be the conversion of the fuel system to unleaded. All that means is a change to the filler neck and fitting a return fuel line.
The 1JZ in a VL is an awesome beast - put out approx 300HP at the rear wheels with a few simple mods. Cost $5000 two years ago so a lot will depend on the price of a good halfcut.

Hi,
Dunno why you are thinking that the VH is heavy. It weighs only 1300-1350kg with that 6 cylinder. Putting a lighter alloy Toyota V8 or even the six would make it lighter again.
No need for 350 Chev V8 w/ Nitrous Feed!!!
Thanks.

If you can fit it in a 327 it'd be awesome. I think they're 6.3 littre. Well sought after so expect pay a mint for the engine. Unbrekable moter and can get going hard. Would be a lot better than going for a Toyota engine.
Note: 327 engine are around the $10k mark minus the engineering but well worth it as they don't break ( well if your nice to it ).
Best of staying with the 6. It's more than likely an auto anyway ?

a 327ci isnt 6.3 litres .. thats a motor with less capacity than the current gen 5.7 litre ( which in old terms is basically a 350 chev )..
You need to do a little more research before claiming an old pushrod 327 would be better/more reliable than say a modern 1uz mate ..
you must be thinking 427 - thats more around that mark - but still a dirty big fat pig of a motor for a road car
Sorry

It's 5.3 not 6.3 my mistake.
Had 4 bolt mains too. Only reason you'd go to something like is because you can't break them. Their stronger than the inline 6 Toyota moters by a long shot.
|
so this 327 can make 1000hp at the wheels on stock internals then? 
and $10000 for just the engine is ripped off!

I didn't say that at all. Yes Toyota are stronger with standard internals.
But there are a couple of facts. No way on earth a 6 wether it's a inline or V can gather more tourqe in comparresion to a V8.
Basicaly that means once it's all modded up the V8 will have the most tourqe.
Correct me if im wrong but i don't think the 2.0 inline 6 cast iron ?
So in theory and from i've learnt cast iron would be far stronger than the material made to make the Toyota inline 6. Also the moter is very heavy.
$10,000 isn't too much of a rip of. If your going to pay $6k for a engineered inline 6 tt your better of getting the 327 for double the price imo.
Also the Toyota inline 6 tt only has 2 bolt mains? The 327 has 4 bolt mains.
There are a number of things that stack up. You could be there for hours writing the good and bad points on each moter.
They both do the job. Toyota is stronger with standard internals but won't satdn a chance in end.

Hi,
Your not comparing apples to apples here.
A Toyota Inline 6 with "Twin Turbo" will be a far better motor than the 'beefed up' 327 V8. However, TT the V8 and you'll be in for some serious power. You can't really compare a Twin Turbo Six to a NA V8, even though the V8 will ultimatly have more torque than the six.
You will find that a 327 V8, even though strong and can deliver high power figures will never be as 'modern' as the Inline 6. The 6 just has too much engineering and years ahead of the 327 for the V8 to be a match. Sure..you can get big power..but you can do it with the 6 just as well, with probly less money and more reliabilty.
If you were to really want the V8 option..why not go for the GenIII 5.7 V8? It's modern, it's powerful and can pack a real punch. I think Comparing such a motor to the Inline 6 is a better argument. Simply because they share the same technological advance as each other. Just my .02.
Thanks.
McFly.

Who says that a V8 has more torque than a six - they obviously haven't seen the torque from the VVTi 1JZ's and 2JZ's. They have more torque (and over a much wider rev range) than the Chev LS1 motor.
If you want to go the V8 way there is no going past the 1UZ motor. It is light weight, four bolt mains, quad cam and multi valve heads to start with. Add a blower of some kind and they produce awesome HP without replacing / rebuilding the internals like the Chev motors.
Remember modern V8's aren't the same torquey motors like they were 20yrs ago. They don't have much more torque than a 6 these days.
Oh, by the way it's not something I have read - sitting in my garage is a single turbo'd 1UZ Soarer, a VVTi 1JZGTE Lexus as well as an Commodore SS with Chev LS1 engine. What more do you want for a comparison.

The GEN3 chev isnt exactly modern...
Its still a 2 valve per cyl pushrod V8 - very similar to the original chev 350 from the late 50s or 60s.
The only real difference is that the gen 3 is all alloy and fuel injected.
They can still be made to go damn hard tho but still in an "old school" sort of way.

1UZ 4 bolt mains????
Try 6 Bolt mains!!!!
and you can rev em to the limiter with a glass of water on the the rocker cover or even a 20c piece on its side.
With some nice head work and extractors expect well over the claimed 206kw
another word I'm not a fan of is PUSHRODS.
My 68 crown had OHC so can some one explain y a 2005 model common - whore is still push rod??

you are forgetting that the 6 has forced induction. The Ford Typhoon has the most torque ever from an australian made car and it is only a 6.

I don't quite see what you are trying to get at here. Are you saying 2L inline six as in 1g-gte? If so, then I would go a 327. I was referring to a 2jz-gte considering the $10000 price tag of a 327. Also, 1g's, 1jz's & 2jz's are cast iron block. That is why they are heavier than 1uz-fe's.

Maybe after you give the v8 some forced induction then it would stand a chance against a 2jz. Otherwise, IMO the 2jz would slaughter it. Look at Norbie's ma61 with 2jz. Running near stock with a boostcontroller ran 12.5 on street tyres!

no the typhoon does not have the most torque from an australian made car csv which if I'm incorrect uses base model commodore and build them up thus making them australian made and have had the 6.5l producing 570nm+ of torque they also produced a supercharged holden v8 a few years back that had over 700nm of torque thus making it more torquey than any pissy 550nm typhoon.
