Mazda 3.5 SLT conversion

[Vern]

So does anybody have any experience with this conversion that M&D do?
Land Rover conversions - M&D Engineering (http://www.mdengineering.co.uk/)
Basically i have a 94 rangie i want to diesel, and the 300tdi and td5 are out of the question. I'd like an isuzu but would love it to be auto, then i came across this conversion for the Mazda 3.5 slt engine into a rangie with the ZF. This engine mainly came in Mazda/Ford T4000 trucks. in stock turbo form put out 135bhp, 277ft/pd, so with a bit of boost, intercooler, fuel i think it would go ok.

So does anybody have any info on this engine? Are they ok.

I've heard rumours they're a perkins motor.
But I have no proof.

[Vern]

yeah pretty sure it is, based on a 4.182 i think

4.212 is the 3.5 litre perkins. Might need to park a mazda next to a massey and see how close they are.
The 4.182 is 3 litres, might share parts, might not.

Vern,
Another unbreakable big cube jap diesel. Pretty gutless as an NA, but turboed etc probably OK. I'm not sure how much boost they can take, but I know they go forever in the Mazda Parkway bus and T series trucks. Ford traders were also a derivative of the T3500 truck.
They are a Mazda-Perkins outcome, the shared a fair bit of technology(If you can call 1950's engine design technology!) and I believe Mazda made the heads and pistons etc etc .

All in all a pretty good alternative engine for a RRC, what did the SLT come out in in australia? I can only place the T3500 non turbo engines by memory:(

Don't know what the turbo model came out in, but you can get them as an import. I just picked up a good runner n/a motor which doesn't look that old and the pump looks pretty new for $500. So for that price i thought i might give it a go. Yes gutless as a n/a, but good low down torque, so i figure, turboed, cooled and tweaked it should be pretty good in a RR. not quite izoozoo but up there.
Main thing is AUTO:D

Put an auto behind the 4bd1, there is a mob in the states that make an adapter for the 4bd1 to th700.

Do you reckon the 700 would survive?

At least one guy on 4BTswaps.com is using it and it seems to work.
Mind you, the Isuzudieselswapper kit adds weight to your flywheel, something which I think may help any gearbox live behind the Isuzu.

My Isuzu 4BD1T flywheel is around half the weight of a cummins 4BT flywheel.

The reason why i kept my last T700 to LT95 conversion, but i would like to give the ZF ago to see if it works as it would be easier, and seen as this conversion has been done and proven (well in the uk it has) i thought why not

[Corgie Carrier]

So what are ya gonna do with ya t700?

Is the lt95 transfer better than a lt230?

Neale

[LOVEMYRANGIE]

I've heard rumours they're a perkins motor.
But I have no proof.

The Mazda SL (T3500) is an all Mazda engine.
The following are Perkins:
S2 (4.135), XA E2500 (4.154), XB E2700 (4.165), HA E3000 (4.182) YA E3800 (6.231) and ZB E4100 (6.247).

The SL-T3500T was found in the Mazda T3500 and the Ford Trader.

There are 3 versions of the T3500 being MK1, MK2 and WG-II. The WG-II can use either an inline or rotary pump.
MK1 will have silver rocker cover and 5 digit engine number, MK2 has black rocker cover and 6 digit engine number and runs up to 1992. From '92 on they are WG-II series which are generally imports.

With respect to the ZB, there is a Mazda spec E4100 and Ford trader spec T4100 and a ZB Kia motor spec.
I HATE THESE THINGS WITH A PASSION!!!!!
People never have the right info on them and you NEED the right info as the SL will have two oil pump drive locations, 3 different pistons, etc etc etc.
Biggest problem is with the sump rubber bungs. These tend to get pulled out and chucked away or damaged during a robowash, but do you think you can buy them???? NOOOOOOOOOOOOOOO.........
I have 3 of these on the go at the moment as complete engines and I can tell you i will be glad when they are out of my warehouse!!!!!!
:censored::soapbox::rocket::woot:

[Vern]

So sump rubber bungs and info, is that the only major problems?

[LOVEMYRANGIE]

No its not. Then you have to deal with imports that have a piston/injector combination that is no longer available or a combination that requires injector and pump change.
I had a customer with the first combo. Told him he can have a kit for a different model spec, but I am going to stamp the invoice with a big "NOT REFUNDABLE / NO WARRANTY" stamp on it.
Really i wouldnt bother with one unless you got cash to burn to try it. A 4BD1T is 3.9L as opposed to 3.5L and the 4BD1T is a far better engine.

[Vern]

So as you've said, getting bits is tricky, but what is wrong with the motor?

Well, they have only ever been installed into a truck and one would expect it to drive like a truck rather than a 4WD.
The rev limit on it will be the restrictive thing and I would be careful running a turbo or intercooler on it unless you get a turbo spec engine. There are considerable differences with the piston crowns in the NA and turbo versions.
But on top of that, why bother????? If you want to do something "different" run a 6/71 blower on a V8 or twin turbo one. Better still, twin turbo a 6/71 blower.
Dont put a mazda engine in a Rangie... how fkn embarrassing!!!!! :o:D

[Vern]

So basically nothing wrong with it then! Its goverend to 3650 (50 more than a 4bd1). And its not to be 'different', i want a diesel that i can stick infront of a ZF, but i don't want a 300tdi (got one already) or a TD5. You can buy a bolt in kit for it, so thought this would be a good choice. Sorry that its embarassing for you aswell!:(

So you just described a 4BD1, truck like, with a restrictive rev limit and diffferent pistons in N/A compared to turbo form, sooooooooooooooooooooo, is there actually a reason to dislike the engine???? or your just waffleing about blowers and twin turbos and other unrelated stuff:p

[Rangier Rover]

There was a green Rangie getting around in Tamworth NSW with Spazda 3.5 out of ford trader up to ZF and the chap who owned it was very happy with the performance and economy compared to other options at the time.
I think it would make a good conversion. Much smother running engine than some others:p
The few Trader trucks I've come across around here have all had a good run with the 3.5 diesel.

Cheers Tony

I cant stop you from doing it, but being a diesel engine supplier, dont get caught with an imported engine.
Find one from a local spec truck. What was delivered to Australia for local compliance is different to what comes out of Jap delivered grey imports.
Injector pumps, injectors etc are not the same as Aus spec in all cases and can be near impossible to source.
Most local engines you find will be in need of a rebuild unless you get a really good one so be prepared for $$$.

Mate you would think that you knew Mal from Mornington Prestige, He has done both the 6/71 and the twin turbo on 3.5 rangie and 3.9 disco respectively.

I have also heard not to touch the import stuff due to these sorts of problems and that was from a parts guy at CAT and was specifically about their stuff so probably not so important here but I thought may have been of interest.

[Bigbjorn]

They are a Perkins made by Mazda. Pretty much a bullet proof little engine. Only problem I ever came across with them was after they went from a stop cable to a solenoid stop in the injection pump. Sometimes when the battery was down a couple of volts, the starter would spin the engine over readily but leave not enough juice to open the solenoid stop, and engine would not start. Was pretty mystifying until we worked this out.

[LOVEMYRANGIE]

The SL is not a Perkins. See my post here (http://www.aulro.com/afvb/837037-post15.html) regarding Perkins derived engines for Mazda.

[Bigbjorn]

I am thinking of the one in 80's 4000 Mazda trucks. Always understood they were Perkins built by Mazda, sure looked like a Polly Perkins.

[LOVEMYRANGIE]

Your thinking of the TF.
The SL (T3500), TF (T4000(, and TM (T4600) are all common family built and designed by Mazda.
All the others as per previous post are Perkins designed built under licence by Toyo Kogyo (Mazda) Japan.

Not importing, i have a local one. So is that ALL that is the problem, getting bits? Nothing actually wrong with the engine itself? Oh and i'm not asking you to stop me from doing it, i'm asking for constructive comments and knowledge about reliability and faults that these engines may have. So far you have given me no help other than you don't like the import models. :(

4.212 is the 3.5 litre perkins. Might need to park a mazda next to a massey and see how close they are.
The 4.182 is 3 litres, might share parts, might not.

A 4.212 is a de-stroked 4.236 and it is not a Mazda engine.

[Dougal]

Is this the one?
Swaraz Mazda T3500(Diesel)4WD-BT,Swaraz Mazda Limited,Swaraz Mazda T3500 Trucks (http://auto.indiamart.com/trucks/swaraz-mazda-t3500/)

Looks like it's just stopped production.:D
100mm bore, 110mm stroke.

That's a lot closer to square than most diesels that size. The Isuzu 4BC2 is 102/100 but it revs to 4200.

[isuzurover]

A 4.212 is a de-stroked 4.236 and it is not a Mazda engine.

AFAIK the 4.212 has a 98.7 mm bore or something like that, not 100mm like the T3500.
