If theres such a thing, 

im looking at an 16-20 8v vauxhall engine conversion

Is there a pretty staight forward conversion??

 i just want more all round power for the Mini  to be super reliable and have 5 gears, even a twin choke weber would suit me fine.

its a daily driver, needs to be able to motorway cruise better, any ideas / info would be ace.....

 thanks in advance

Never understood the logic of fitting a engine with injection as standard but removing it to fit crappy carbs.

Also pay attention to the gear ratios, that could make or break a daily driver if on fast roads. My k series on both 3.9 or 3.7 boxes and 10" wheels have been like 4.5 to 4 grand on motor ways, which can be a little tiring.

Why not just fit a taller diff to the A series in it?

 

I find most people who go for big HP conversions wind up rarely driving the car due to other complications/issues caused by the conversion. why not go with what you know? There are lots of bolt on power improvers for the A series, and if you're looking for lower revs on motorway, a 2:76 as iftted by the factory will do it. Mind you, changing the engine does nothing for the overall noisiness of a Mini at motorway speeds - wind noise, tire roar, and all the rest now come thru with absolute clarity!   :proud:

 

I built a 1275 up to about 100 hp and it pulled at 2:76 easily, cruising at 75 mph was nothing for it.....but I still wore earplugs on longer trips of a coupe hours or more....

Cheers for bringing it back on track Magneto, im hearing what your saying,but as the Mini is a bit of a hack, i think ive mad my mind up on engine conversion.

Im looking forward to the transplant, i know its not everyone bag but its my motor.. Being from the midlands we always do M5 south journeys and i want to use the Mini without the struggling issues, even though the sound of your engine probably wouldn't have them, but cheers anyway

I think it's mainly down to the fact a true 100hp A series engine, not a 1275 with a stage one kit is realistically £2k? With a lifespan of a couple years between rebuilds?

Rovers are like litter, a 100hp engine will set you back £100 quid and is already 16v, fuel injected etc, things people litterally spend thousands on to improve their A series.
Similar can be said for Honda's and vauxhalls.

Well, that's a good point, we don't have access to all these different choices here in the States. Honda D series is fairly common tho…..

The CG13de from a Nissan Micra looks to fit without hacking the wings about. 

If I were going to do it it would be that or a sohc Honda 1.6. I always wanted a G13b to replace my swift gti but there's next to no aftermarket support and donor stock is hard to find.

 

Also consider the rolling diameter of your wheels, I am not sure there is much difference until you hit 13"
