It's almost time, the 2.2ltr push rod 4YC is nearing it's EOL after a fun 325,000 Kms. Pretty good for a 4 pot I reckon.

Resisting the urge to go stupid and spend mega bucks on what is essentially a weekend toy that I just happen to drive to work (100Km round trip a day) and after reading the forum comments regarding the popular transplants, i.e. CHEV V8's and Holden V6's, my question has anyone gone down the late model diesel, pref. the 3.0ltr over the 2.8?
Surely the standard drive train in the '86 can handle the extra torque.
I'm interested to know if anyone has done this and if so are there kits available such as MARK'S 4WD does for the V6's and V8's?

Thanks in advance guys/gals.

Hi Stinky
There is plenty to change going diseasal, with diff ratios being 4.8 on yours and 4.3 for the diseasal. The easiest conversion would be another Toyota motor, maybe a fuel injected one from a Celica, or v6 Camry.
Look up Chaos 4wd in a search engine. for hilux gear like double transfercase adapters, then an auto can be real good in the bush aswell as on road.
Look up the second hand jap motor importers and ask them for a recommendation.
They sell all the performance engines up to the 4 litre v8 lexus.

The diff ratios arn't an issue, the lower the better I say. Already with the 33's I could use a little less.

Mmm V8 Lexus, actual, I have done a little leg work and did think about the Lexus v8 as toyospares had one in the front showroom, interesting, different and difficult spring to mind.

I was thinking of another toymotor, just a later version and diesel.

The commodore V6 conversion is terrific, it gives the rig so much more driveability with heaps of torque and yet no bad side effects! Personally I would look at keeping the auto with it as well, it is a terrific combination, power, economy etc.

I agree with Dozer, the diesel conversion would be pretty involved, not impossible, just no where near as easy as the V6 conversion. There are heaps of guys out there specialising in this conversion alone!

Thanks Matt, what are the pro's and cons between retaining the 5 speed and going the Auto. I assume you went with the T700?

I was told by a mechanic that when the holden V6s' are put into Hiluxs, Forerunners etc that due to the offroading, places more stress on the motors resulting in blown heads/ cracks etc - they were designed for what they are ripped out of. He mentioned something that appeared to make sense - vehicle designers don't sit there for months or longer building the vehicle around the motor for no reason.
It might be sh*t but it made me shy away from buying a Hilux with the v6 transplant a some years ago.

I agree totally with what that mechanic told you and there are some engine combinations out there that I would NEVER even consider fitting to this vehicle. Like the high reving and low torque engines that some are considering. 4AGZE, etc!! These are designed for a light car with no torque requirenments, they all have to rev to get moving, can you imagine these in a 4x4 weighin in close to 1500 kgs, WHAT CLUTCH??
But with the GM V6 you have to remember it wasnt designed for the commodore either, ever!!! It was shorhorned into the VN to beat the EA falcon when Holden ceased production of its own engines with the VK (the last holden six). But it did beautifully in that car, being a relatively light (alloy) powerful and also rather simple engine! Prob the reason it has become so popular in the Hilux for repowering, it walks over the 4Runner V6!!!
As for the auto, well if you dont want to get Marks to kit you up a small truck 5speed to handle the extra power, Im confident you wouldnt be dissapointed in the T700. Full lockup 4 speed auto that you KNOW can handle the power of the V6 and for sand and mud driving...they certainly perfore terrific.
Goodluck with whatever you choose, some solutions are simple and inexpensive, some cost a little more but in the long run..if you do your homework, you get what you pay for!

The V6 conversion is good but can be very expencive, i did my own and cost me approx $3000 but some have payed twice that.

If you want to save some money why not rebuild your 4Y engine ?

You could re bore it and fit over size pistons, fit a new camshaft designed for more torque, fit a Weber 3236 carby (Webers go well with this engine) with extractors and a free flow exhaust.

Has anyone fitted a twin cam/multi valve fuel injected 4 banger from a street car ?
I recon that would be good !

Even a 1.6 litre 4AGE will kill the 2.2 for power(even without the 20V or the supercharger). The 2.2 and the 2 litre before it were and always will be boat anchors. Reliable maybe but gutless, heavy and old tech.

Other cheap jap import engine options like 18RG's (getting very rare these days) are possible. Also 3T-GTE's used to be very popular swap.

I think te best bet would be one of the early toyota soarer 2 litre NA, Turbo or Supercharged Inline 6's. They're very small for a six, and very cheap for 160kw. I've seen these engines at importer/wreckers for $395 with turbo or $195 for the NA one.....

You might need to use a front mounted electric rad fan though.

With the effort involved in diesel/petrol conersions I'd say dont do it.

Commodore V6's are cheap - but the adaptor plate alone doubles the cost. Then add in fuel injection computer and all those hassles and you won't get out of it under $3000 even if you can do it all yourself.

I would think that keeping the car as close to standard as possible this way it is easier to sell and you dont waist money on an 86 model car!!!
Insurance companies dont like modified cars and they can refuse paying out .
Its nice to put bolt on extras like lift kits and stuff as long as they can be removed.
Sell the car and buy a later model with a bigger petrol or turbo diesel.
That sounds like something my old man would say..hehe
and im not even 40 yet !!
but what the hell . if it feels good do it!!

Thanks all, as expected I got a very diverse response. I think it's going to come down to the best deal I can get for either a later roady 4pot or a V6.

Here's an update...

I've gotten a line on a VR V6, pooter and loom for an auto, with a rebuilt bottom end for $750, never considered going auto, but given this thing spends most weekends up to the arches in mud It may be the go. T700's are expensive however, Argh, too much to think about.

If you are wanting to go v6, then look up damaged cars at pickles auctions and get a complete writeoff for 1k.
You can put double transfers on the lux if you dont like the downhill braking of the auto, rock climbing...the auto wins hands down.

Heres more to factor in
On Ebay at the moment, is a chev to lowlux bellhousing (up to 51 dollars at present) So thats a 4.9 holden motor or any chev v8 Remember the diff ratios are only siuted if you put 38's on
