Can an a series 1275 mini engine be fitted to a morris minor?and if so what do we need to get to change it;thanks dave and claire

Essentially NO. You would need to change the crankshaft for one with a flywheel flange - and then you need to organise a seal for the rear main bearing. Nothing is impossible - but it's not really worth it.

Has anyone gone to the bother of doing this? As inline 1275s seem to be getting more and more scarce.

I believe that in the New Year JLH will be releasing a new conversion for the 1275cc Mini engine, you will just have to be a little patient.

And has been hinted already - quite deep pockets!

Well sometimes one just has to accept that somethings do cost. It is is no way disproportionate to the amount of work involved and the time concerned with the research and development. I'm sure that conversion the is not beyond the capabilities of some on this messageboard. However we will not be able to give details of the method and parts required, unless you are a genuine customer. I'm sure that once the rand d has been recouped then this might change.

Sounds like normal practice, thats why new products are so expensive at 1st.

Aye - but is the end result worth the wonga ?? Still plenty of 1275 in-line engines out there - just not in Scotland (although I do have one in my sights). And there are loads of 1098s around - which can be quite easily encouraged to give 70 bhp which is plenty for a road car.

There ain't no substitute for cc

The idea to modify the mini engine was purely due to the difficulty in obtaining good 1275's. Also the 1275cc would be the entry level, with engines offered in all variants of state of tune. A standard 1275cc will produce around 80bhp with the conversion which also includes carb and manifold from the MG. If you look at run of the mill 1275 rebuild costs and compare them with the modified mini units one could see that they represent excellent value.( I know prices have not been mentioned here to do the comparison) but a PM could work.A modded 1098cc motor producing 70bhp will hardly be drivable or even reliable as everyday transport.
Totally agree Pete

Which is why I suggest 70 bhp - which is attainable for approx £40 outlay and an afternoon's work!

That's quite a lot of horses for a 1098.

Can I ask how you would achieve it for so little outlay?

Appologies for the typo error BM, I have amended my post

I just love that! Maybe for you this is possible but I doubt it. I double doubt it in an afternoon. Are you going to make your own exhaust or nick it from someone? Likewise all the other shenanigans you need to output 70bhp from a 1098.

Tell you what BMC, you've made my evening, Can't stop chuckling inside.

Can you give details? I'd like to know what to do and where to get the necessary bits.

JimK i suggest you obtain a copy of "Tuning the A series Engine" by David Vizard. covers every aspect of tuning the A series engine, worth every penny.

bmc i dont think 70bhp is attainable from only £40, for £40 I reckon you could get a larger 1.5" or 1.75" and alloy inlet, and with the old inlet manifold cut off might get you to about 55-60BHP...

No, you're spoiling it - it's ALL of US who are wrong...

How much of the information in the book is useful for somebody without either a machine shop or much cash? Can I make use of it without spending much cash?

Does it cover forced induction?
