Well I've spoken to Mini Sprocket, and hes using standard 1275 pistons... surely the powermax are simular, only a bigger o/d?

[The Matt]

Depends what machining is needed really. I mean, is it a case of machining them to get the CR down, or is it for a recess in the crown for valve clearance etc?

[MiniKid..]

I think its for the valve clearence

dude im prob ages behind but have you seen the bmw engine on the bay??? K engine looks like a good one but not cheap..

[Dog]

I'm sorted now cheers dude!

I'm getting myself a K1200RS inc carbs etc etc
Specialist comps are doing the machining etc - all ready to bolt together...

Just need to save up... anyone got £1800 they can miss?

[mad4mins]

eeek thats a hole in your wallet!! have you bought that booklet they do on how to fit a k head... just wondered what is involved...

[Dog]

Its on order
But that £1800 inc's-

R1200RS head
R1200 carbs - and everthing that goes with it
ALL machining to the block and head
and the fitting kit...

and after talking to them - on my 1380 - I was only after 120-140@wheels, they said I could quite easily get that, and have the torque too - being 16v

The way I looked at it is, the 16v conversion - its just a cheaper form of 8 port...

[mad4mins]

cool!! its not that bad then i suppose.. are you going to beef up the cams aswell while your there??

[Dog]

I'm not sure - I'll have to find out - but std cams AFAIK are about 280degrees, which is fast road in a Mini cam... I could beer them to 290, or maybe even 300, but then I'll loose the smoothness I'm after....

[$way]

this'll be a treat. caint wait to see the kit when it arrives.

[Levi]

Just wondering have you looked at the insurance costs yet? Was wondering whether there would be a lot of difference between the K head conversion and one of the more popular vtec/vaux engine transplants...
