Swap a 1995 80 Series 1FZ-FE with a 2001 100 Series 1FZ-FE compl motor

I have a straight LPG falcon BF an goin somewhere out of state
I have to be very cautious about LPG out lets .the new roadhouses are not putting it in so I have to go off the HWYs into the towns to find it

don,t go with LPG .
cheers mechpete

Hi Ron,
thank you for you reply, info & advise.
I am aware of the LPG requirements as to re-certification, red diamond stickers, etc as you have outlined.
These are factors that I have been factoring in with the pros n cons and would be address 'if' I went down the road of this engine change over.
Rest assured Ron, that I would NOT be doing the transplant my self, it would be done by a fully qualified mechanic and done to required statutory regulations and requirements.
I have been doing loads of trips down south to my property I am renovating 900 km round trip maybe 2 times a month +.
My question is not re: the LPG side - I could have that removed completely and sell the LPG off.
The question I am asking is transplanting the newer 1FZ-FE into my 80 series and run it as a designated petrol engine.
Not LPG certification etc etc.
Just the different engine number inspection not a big deal at $116 for the inspection in W.A.
I'm on a disability pension so I have to look at keeping my outlay costs down hence any 'major work' needing to be done on my 80 would have to handled by qualified mechanics
I don't know yet what it would cost for a engine rebuild on my existing 1HZ-FE My guess is that I'll need to be sitting down when I'm told the cost. :-)
A complete newer motor for $1500 is a good price from what I have seen of prices being asked for 2nd hand donor engines
I have head n seen the donor engine mentioned running in the original 100 series he owns and it is a solid operating unit.
Been well serviced and maintained by the 1 owner from new.
His doing a diesel conversion of his 100 series in prep to head off to explore OZ next year.
But hey! I'm looking at options.
If I can get my motor fixed for $1500 then sure I'd go that route.
Much appreciate your reply and I do further appreciate you stating the legal requirements, which I agree, do and must to be insisted on when doing engine swap out and or LPG work etc.
So, the question still remains - will a 100 series drop straight into a 80 series etc as outlined in my original post.
Cheers and have a great weekend.

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.

Hi Ron,
I just put an UPDATE on my Thread.

Copy here for your info.
I do appreciate your frank and honest comments and I looked at juts getting a 80 series 1FZ-FE as you suggested.
I could get one from QLD freighted here for under 2k - a good runner and sound motor - would only need the Inspection for engine change over.
Thank you again and I'll see what the problem really is before looking for another motor as indicated in my Thread UPDATE.
Cheers Phil

Thread UPDATE for your info:

UPDATE:

Hi all,
after reading your comments, information and suggestion.

I have decided wait and locate a good running 80 series 1FZ-FE ) if I do in fact need a full engine rebuild) that will be a straight forward transplant without any 'hidden unknowns' as indicated in some comments received.

I'm getting a constant knocking sound in the motor when idling, revving slowly and when driven, so for now I'll put it on stands and go over every area of the engine and see if I can isolate the problem.

It sounds to my untrained mind that it could be just piston rod bearings needing replacing.
I may just be a simple fix - fingers crossed.
Well see in time to come and will update my post with outcome at a later time..

Thank you much for all your informed comments, advise and suggestions.

A 'SPECIAL THANK YOU' to Ron for your detailed comments, advise, information, suggestions in your replies.
Very much appreciated

Keep em rolling.

Cheers
Phil

That's US$ plus freight.....somewhat prohibitive

GBC - You've linked to an American website, and it is not economic to freight in a reconditioned engine from America.

The US$4490 price converts to AUD$6500 - the freight component involves freight cost from the reconditioner to the port, crating charges, shipping charges, LCL (less-than-container load) charges, Quarantine and Customs inspection and recording fees, bond warehouse transport and storage fees (your item is taken to a Customs warehouse upon arrival for Quarantine and Customs inspection and approval for importation), Port charges, Port Security charges, and Freight Forwarder or Custom Brokers fees.

I've been there and done that, a number of times, and I can assure you, the reaming with importation is extensive and thorough.

As an example, I bought a large earthmover transmission (pallet load - and 450kg) from South Carolina, for $1800 - when I finally loaded it into my ute at Fremantle, the total cost was $3400. That was around 8 years ago, too. All costs have gone up, since then.

If Customs/Quarantine find even a sniff of asbestos in the engine (some gaskets still contain asbestos), you won't even get the engine, it will be re-exported, at your cost.

Cheers, Ron.

Yep, my blue, I assumed it was a local site. I was getting excited too. $6.5k odd bought a Spanker long motor from the dealer last I looked in the early 2000’s.

Phil, change your oil filter and cut it open, see whats caught inside....if it is a bad knock internal, you will find white metal in the filter
