Hi

I want to know if it is possible to fit a MGB B-series engine into a mini (clubman shape) without modification?? If modification what do you think will have to happen?

Thanks, every comment is welcomed :D

Short answer not really , long answer involves a lot of questions , the biggest one being why would you want to use an old design , heavy 5 port engine ?

The B series engine won't fit onto an A series gearbox , the Austin 1800 used a B series engine with a front wheel drive box and while I've heard of a couple of these being done (one supposedly for a high torque mini in the original Italian job but never confirmed) in the UK I have no idea on the extent of subframe and body mods needed other than it just won't fit into the standard mini subframe . Anyway , even after converting it you are still left with an older engine with a 4 speed box whereas for similar work you could have a Daihatsu Sirion , Swift Gti or similar basic engine (or go turbo Daihatsu , Swift or Toyota 4efte if you want) with 5 speed box and a more efficient and powerful engine . A modern engine would also be a lot lighter than the B series (a mate of mine is from an MG family and I've helped move countless engines about with him , a B series engine weighs as much if not more than a modern engine/gearbox combination .

B series was a boat anchor IMO, whether 3 bearing or 5.
Mods that give more HP in an A series often just give more noise in a B series. :lol:
And, they weigh a friggin' ton too.

Thanks for your thoughts and advice

That is all very true...just I was thinking B series engines have larger capacity
Most were 1300 standard plus so I thought yeah but if they are heavy, old and
Don’t fit a mini than it’s a no go

Thanks

remember there is the 1275 A series. If your after power and still want it easy for the road, you can bore say 60 or 80 though, nice cam (i.e. RE13) 1.5:1 rockers, a bit of head work and maybe stick a turbo onto it and you will have a nice set up

If you are going to turbo it, the RE13 is not suitable, get an RE13T which is designed for turbo and produces big HP, whether in a 1098 or 1275.
The lobe profile is the same, but the LCA is modified a lot to suit a turbo.

what does LCA mean? has it got something to do with the timing of when the valves open/ close?
