Hi Phil - Ahh
well, that clears up the LPG question, then. In answer to your question - will the 100 series 1FZ-FE drop straight into an 80 series - the answer is a qualified, "Yes, but not without some modifications".
Your "early series" ('93-'97) 1FZ-FE is fitted with a distributor. Depending on the model it could have either a carburettor, or be fuel injected. The GXL and VX are the fuel injected versions.
The "later series" 1FZ-FE ('98-'07) received a host of major engine upgrades, and it is fitted with direct coil ignition (no distributor).
The later series 1FZ-FE got a redesigned head, more compact pistons, updated throttle body, an improved intake manifold with longer intake runners, 4 nozzle fuel injectors to improve fuel atomization - and the direct ignition - all of which led to a small power increase. The early 1FZ-FE made 212HP, the later 1FZ-FE made 221HP.
The later 1FZ-FE was also fitted with other revised engine components/accessories such as a larger power steering reservoir, modified intake ducting, and of course, a different ECU.
Now, this is where the difficulties will come in - finding out all the precise electronic/electrical/wiring differences between the two models.
As they say, nothing's impossible, if you want to throw lots of money at the project.
But one thing I've found, after buying and owning many new Toyotas since 1977, those Japanese engineers are buggers for changing designs, simply because they can.
I can recall one of my LN-106 Hiluxes needing a replacement wiper blade and arm. When I went to buy it, I had to specify the exact MONTH of build, as
well as the year - because there were THREE different wiper blades and arms for the LN-106, in the one year of build!
So, all I can advise you is - yes, it is possible to do the swap. The engine will bolt in.
But - No, I don't know exactly what electrical/electronic/wiring needs to be altered/upgraded or changed, to get the engine operational.
If you acquire the 100 series engine wiring loom and ECU as part of the deal, that's a big step forward. Making it all fit and work, is another question again.
It could run into some serious money - we're talking Toyota 4WD's here.
It will almost certainly require a dedicated mechanic, with extensive Toyota engineering/design knowledge, to do the swap.
If I were you, I would on-sell the 100 series engine at a profit and either - 1. Pour the profit into a rebuild of your current engine - or, 2. Buy a low-km, '93-'97 1FZ-FE import engine. The low-km import engines are a much cheaper option to a full rebuild.
A low-km import (these are always in quite good nick) will run to about $2750-$3000 (plus installation costs).
A rebuild of your engine will set you back around $5000, without removal/installation costs.
A good quality engine kit (pistons,rings, bearings, gaskets) is around $1000, a reconditioned head is around $1500 - so you can see where it all adds up, when it comes to a full rebuild.
The important thing to remember when replacing/rebuilding an engine, is to ensure that all hoses are replaced, and to ensure that the cooling system is in top condition.
This will mean a radiator service at least, and perhaps a new radiator, if the old radiator is deemed to be suspect.
Cheers, Ron.
