looking to start a new project sept/oct time somethin to keep me goin now if i were to stick with a a+ block and swap heads to
A bmw k1100? head what is the rough bhp upgrade anyone any ideas would like KAD but you lookin at a few grand for head plus manifolds etc will the bmw head only work on 1ltr or will it be ok to use on say a 1380,1400 motor????

[miniboo]

the bmw head should not be used on a 998. it is for large bore only so you are fine with that.

wayne let us know what you find out.. i like the idea of the bike conversion just not the cost

the bmw head should not be used on a 998. it is for large bore only so you are fine with that.

Can you not use the 8v on a small bore or something? I'm sure I've heard Morspeed have done a 998 variant with a BMW head, might be wrong though.

[scottyegg]

you can use the 16v on a small bore i was speeking to the owner of SC specil components at mini in the park
and he said yes it will go on a 998 with will require more fetterling ect to fit unless he did mean the 8v


also a standerd 1275 with a 8v head (bmw k1100) pumps out 107bhp thats with fuel injection ect but a standerrd head no porting or anything)

and 16v they say will pump out 140+ easy on a 1275 standerd thats from 62bhp so a 80bhp increase give or take

found 2 links to the fitting guide but no prices doesnt seem to technical but still could be a nitemare to do cant find moorspeeds website but am sure i have seen it before wonder if they do a kit an how much?

[wayne11]

well actually could be very technical after reading it again lol

[miniboo]

ahh yes my apologies i forgot about the 850 version. i think that was one of the first ever ones aswell.

www.morspeed.co.uk is morspeeds website

[wayne11]

wow/outch £650 for conversion kit +extras cheap enough BUT ........
fully built street sleeper =£3950
sprinter engine =5650

well vauxhall etc is lookin good now lol

[miniboo]

you only save nmoney on things like this when you do the work yourself.

SC components do the kit in such a way that you can buy it in seperate parts as and when you can afford it.

If you search the forums properly, you will find a lot of info on these conversions. Its not quite as simlpe as a straight head swap. Quite a few people on TurboMinis are doing this conversion.
Also dont forget to factor in the cost of EFI unit if u planning on running injection and throttle bodies etc.

and if you do the bmw conversion it is still an A series engined car.

I think i might move this to mini chat for now aswell

[who_loves_the_mini?]

you can only fit the 8v head to a 998 due to the spacing of the valves in the head. would be a great little sleeper if you wanted to keep it 998
