3B toyota diesal

[whispersseries3]

Hi has anyone heard of or had any experience putting a 3B toyota diesal engine into a series 3 engine bay. yeah yeah i know it,s a toyota but it,s also a good engine:wasntme:. any comments or ideas welcome as this good start a healthy argument on converting to diesal versus using toyota parts:angrylock: cheers Leif

What would you do with the gearboxs? It might be better to run to Toy gearboxs rather than the Series stuff for a few reasons. , and I'm pretty sure the Toy transfer has offset outputs to suit the rover axles also. There is a difference though, in that the Rover series axles are 4.7, where the Toy ones run 4.1 for the same tyre size.... or you could just run 37's.:D. Mind you, if you're doing an engine conversion, then you will also find transplanting 40 series diff under it an absolute no brainer, they seem to be a really good fit too.

This is a clip of a toymota 2.7 litre diesel in a shorty 2a:

Sorry for the shoddy camera work, I didn't know what I wanted to record apart from the sound.
I have yet to drive it since it isn't registered but the bloke i'm buying it off says that the engine runs a bit fast for the gearbox-as does his holden powered S3 109. He also tells me, to be totally reliable, it'd need a toyota gearbox and Rangie diffs, but my intention is to get a Rover 2.25D since it was originally a diesel vehicle.

Here is some links i just googled

Thanks thats some usefull info to start on. I have got hold of a 3b diesal for no cost needs new big end bearings. Will have to look into cost of fixxing it up and mating it to the series3 g/box if posible. cheers leif:D

A few thoughts on this sort of question.

Installing an engine, just because you have it, can often be done, and, provided you have the skills and facilities to do it properly can be a very interesting project. But even when the engine cost you nothing, the project is likely to be fairly expensive and with uncertain results unless it is a well tried conversion.

It is very unlikely that the engine's useable torque range will match the existing gearing, so you have to consider changing this as well. Then there is the question of whether the drive train will stand the new (presumably more powerful) engine. Of course you can do as Slunnie suggests and fit Toyota engine, gearbox, transfer case and axles - but if you are doing this, it begs the question as to why not simply get a Toyota?

The Series Landrover is unusual in that it was designed so that the drive train remained the same regardless of the engine fitted (except the V8) - from the original 1.6 petrol engine to the 2.6 petrol or 2.25 diesel. This has the advantage that it rationalises both manufacture and parts supply, as well as making life easier for the owner down the road.

It is also unusual in that it received what is, as far as I am aware, the only engine ever designed and put in production specifically for offroad utility use, in the form of the 2.25 petrol and diesel. The diesel engine in particular, originally in two litre form, was very unusual at that time (1956). At that stage small diesel engines were quite rare, and none (except perhaps the Mercedes) operated at such high rpm. Remember that Rover was shipping diesel engines more than ten years before there was one available in the Landcruiser or Patrol. Even since then, few comparable engines, either petrol or diesel, are capable of operating over the same rpm range as the Rover engines.

This makes an overall satisfactory engine replacement relatively difficult. Most replacements that appear suitable on the surface (i.e. will fit) have problems of one sort or another - typically the rpm range does not match the gearing, but also problems can arise such as fuelling or lubrication on steep slopes. (This is quite apart from problems of actually fitting it which may need changes to the bulkhead, radiator, bonnet, sump, oil filter etc)

Despite this, most people seem to be happy with their conversion of whatever type - this is often simply because the engine removed was completely worn out. Historically many Landrovers were fitted with Holden engines primarily because it was quicker, far cheaper and easier to convert to a second hand Holden engine than to overhaul the Rover engine. The performance boost from a worn out Rover engine to a good Holden engine masked the problems of gearing (often solved by fitting an overdrive - by which time most of the cost saving had evaporated) and as relatively few owners do any serious offroad driving, the fuelling and lubrication problems often took a long time to show. Plus you had the big advantage that engine spares and repairs could be found anywhere, which has not been able to be said for the Rover engines since the sixties.

I have a series 2a, with a Toyota B diesel, and 5 speed from a Dyna truck. I could send some photos through if it helps?

The B is the 3l version of the 3B, and is a good wee engine - slightly more power than the 2.25 petrol, a bit more torque, but far better economy.

On the road it happily pulls 120-140 km/hr, on 32x11.5R16 Mongrels. I`ve had it pulling 2.5t excavators all day every day no problems, it really is a truck engine, so it thrives on that sort of thing.

I`d be looking at the toyota g/box, with at the least uprated halfshafts if you go down this route, and don`t forget you`ll need heavier front springs - as the diesel is a bit heavier again that the landy lump.

If you`re really keen you can get exhaust brakes for the B series diesels - now theres some crazy engine braking for descents.

sadly the 3b got crushed and dumped in the bin before i got to pick it up:(; but i will still look at options as both my 2.6l rover engines are very tired;)

There are plenty of good (diesel) engine options for a series:

200Tdi, 300Tdi

Isuzu 4JB1T, 4BD1(T), 4BE1

Toyota 3B(T), 13B(T), 15B(T)

Nissan TD27

And probably a few more I have missed. Most of these will need a stronger gearbox. All are Direct injection except the 3B and the TD27.

I have seen a couple of 101FCs with 3B(T)s, toyota 5 speed boxes and toyota t-cases. They went well and it seemed a good conversion, but a direct injection engine would be preferable.

The 2.25D is also an option if you are interested in cheap, easy, and don't need super duper acceleration.

I think the Datsun SD30 and 33 may have also been common with the 5sp to series transfer.

You are right - there have been quite a few SD33(T) conversions over the years. All reports are though, that the TD27 is a MUCH better motor, and as they are fitted to every terrano 1, you can get a good engine for $1k from the wrecker.

i am raising the 3b from the depths of the skip bin tomorow hope to find not too much damage, as i would like too keep the old girl as original as pos. does any one know of an available 2.25d engine
