I have an 850 Mini from a faraway country

Post by jaden »

Hello, I am maintaining Morris Mini Traveler in South Korea. Only 1 exists in South Korea.

The supply and demand of parts are mainly brought in through miniseries or Japan, but I have a question

Since my writing was written through a translator, it may not be a bit smooth.

I currently use hs2 carveter and estimate it to be 850cc engine

I want to swap a 998cc engine, but it's not easy in South Korea.

That's why I want to change even the carburetor to hs4, but as you can see in the picture, I changed the brake method, so the manifold seat doesn't come out.

I don't want to ride in this state. What's the best way to do an upgrade in my state?

I can get a 998cc engine from Japan but my Traveler Woody is MagicWand so it's not in the right gear position.
It's the hardest thing to do when you're out of gear

I don't want Minnie to stop on the road anymore.

Please help us, seniors :shock:




Why is the air filter like this?
It doesn't even fit.

Maybe the manifold or cabreta location has been modified a little because of the brakes, but I'm wondering if it's better to have purification or swap

If I keep 850cc, I will have to replace the start motor, A filter, manifold, distributor, etc. and I want to use hs4

If you swap 998cc, the gearbox position is a problem.
Mine is MagicWand, and the gear position is in front

How can I compatible a 998cc engine that can be brought from Japan because the mission is a load change method?

Lastly, would you like to keep 850cc? Would you swap 998cc? 1275cc is hard to get in South Korea

Welcome to the Mk1 Forum.

Note: Your open bonnet photo of the engine compartment has been posted as a 'mirror' image which had me slightly confused at first!

Your Mk1 Mini Traveller has been fitted with later air conditioning which must add quite an extra load on the performance of an 850cc engine when the air con is in use. Air conditioning was only factory fitted to later Minis exported from UK to Japan and were the more powerful 998 and 1275cc engines.
Your Mini has also been fitted with the later combined brake master cylinder/servo which was fitted to later Minis from about 1989. However this should not cause any problems other than meaning less space for underbonnet access.

Your air filter is not original and is probably not designed to fit the Mini. You would be better to locate a standard 850 Mini air filter casing or an aftermarket filter designed to fit your Minis SU carburettor.....although it may be difficult to obtain the parts easily being such a rare car in South Korea!

The alloy Minispares inlet manifold looks like a spacer plate has been added to adapt the mounting for the smaller HS2 850 carb which is probably not helping filter to bulkhead clearance issues....however the manifold should therefore be ok for a larger HS4 998cc carb setup without the adaptor spacer plate.

In the UK originalty is preferred on early Minis so most Mk1 Mini owners here would retain the original 850cc engine and magic wand gearbox which also means a higher value from potential buyers on any future resale.

Are you sure your engine is 850 and not already a 998 transplanted by a previous owner complete with the Japanese air con system? As they look very similar to the untrained eye and as said I don't think air con was ever fitted to 850cc export Minis even in Japan....are any engine numbers visible which would help confirm?

Thank you so much for your answer

According to the repairer, the complex brake master cylinder/serv fitted since 1989 cannot be switched to a manifold with a mountable hs4 shaft.
(Problem of lack of space)
In the case of 998cc car, if I look for stock in minispair, I don't think it can be installed because the shape of the float chamber and the direction are opposite.

Dear mab01uk, I think you asked me to keep 850cc and magic wand. What would it be if I upgraded under the condition of maintaining this engine?


I'm sorry that it's not smooth because it's through a translator



-
Where can I see it's an 850cc engine? I opened the bonnet today and looked at it, but there was no engine number anywhere.

The maintenance shop said that the pointer-type electric distributor and the start motor are engines that do not fit the current 1000cc model

What you can see with your eyes is the magic wand
Can you tell me how to check if the engine is 850 or not?

I suspect that is an A+ engine and therefore not an 850.

The 850 blocks had '850' cast on the back of the block , as per picture.

Not sure if this continued right to the end of 850 production in 1980.

Some/many/most ? of the bigger engines had a small alloy plate attached in the same place eg '1000' for the 998.

The 850 is very difficult to see from above.

With Mini production, there are always going to be variations, so bear that in mind.

As said in previous posts, look down the back of the engine block, quite difficult to see clearly, you will need a bright torch or shine your phone led light and maybe using a small mirror to view. Also the numbers shown in photos below may be covered in oil & dirt!

Examples of 850cc and 1100cc engine cylinder block castings in photos below.

Image
Note: 850 cast into rear face of 850 (848cc) engine block


Image
Note: 1100 on metal plate riveted to the rear face of an 1100 (1098cc) engine block
(The 998cc Mini block would usually have 1000 on the same type of riveted metal plate)


Image
Engine number is located on the silver plate riveted to the block in this photo but it often gets removed and lost during engine repair or replacements.
The UK Vehicle Registration document has both the Chassis and Engine Numbers shown on it but not sure if South Korea vehicle registration documents also have these details?

Hope this helps.

Another variation was the 997 Cooper block that had '1000' cast in.

A+ engines had neither a casting nor a plate indication of size.
