I have purchased my first ever mini (1984 mayfair). It has a metro 1293 engine with stage 1 kit. My intention is to build myself a little pocket rocket with around 100bhp. Firstly is the metro engine (am i correct in saying a+) a good choice to modify as most of the modded engines i see are the a series original engines. And secondly i want a reasonably fast mini but with reliability (am i asking for too much). So the question is: What is the most sensible way of going around this as there is so much to choose from. Please bare in mind i know nothing about these cars at all however have a reasonably good knowledge of most cars.
thanks Neil

Yeah and a 1293 engine witha good stage 3 head will give you 100bhp easily! mine did!
Its not just about the head, u need a cam and a good set of rockers (1.5 rollers)... mine was is a 1293 with stage 3 head 1.5 roller tip rockers and a 286 kent cam.. good for 86bhp at the wheels, about 100 at the fly... it had more to give but was my everyday car, still sweet.
if u want more then say good-bye to reliability.
The gearboxes are good, just the drop gears need upgrading to s/c
Also recommend a cross pin diff as a must for any build over 100bhp
As for your engine people might be able to help if u gave us a engine number... but i'd say it was a A+ from a metro.
Has it got letters cast into the block below the head on the left hand side?

Saying that, theres only minor difference between them, and almost all the parts are interchangeable
dont worry at all about the gearbox or drop gears - they'll be perfect for a road-going car, plus SC gearsets are bloody expensive, spend the money on a 4-pin diff, as it's only about £150 for a decent one

And does this sound a good buy. Also seen a 12G940 cylinder head will this fit?
thanks again

Does this fit both the a and a+ engines then. Does this mean if it's from an a series it's a leaded head ?12g940 is a standard 1275 head.
