a series cylinder head conversions
Turbo Mini Forums

Other than the k1100 bmw bike heads. Has there been any other cylinder head conversions from other engines?

Fiat head on here.

Would that be a punto head by any chance?

There have been other attempts, but non as successful, well documented and value for money as the K head.

The alternative is a lot of buggering around, head scratching and project delays.

Obviously you could go KAD, Jacknight, SC, AKM, etc.

I've noticed that the in thing is the K head conversion but the price reflects it as they seem to go up every time I look.

Ive seen the leyland version of ohc on an a series im suprised no one copied it for tuning upgrades.

I found a thread on the fiat head but it wasnt complete so dont know if it worked at all.

Some one mentioned a R6 head too I I guess that would be the same as the K head in a conversion sence.

The thing with the leyland OHC head was that it was still not a cross flow design. Makes you wonder what the point was, and probibly the reason they never put it into production.

What are you trying to achieve? Being different? or make the engine more powerefull?

I have a "K" engine wich cost me 100 euro. I might have been lucky, try to look on ebay.de

If i have more toys than you when i die, I WIN

The Leyland OHC non-crossflow head was a genuine marvel, despite it looking wrong on paper.

A friend of mine had one fitted to his car (which I think is now at Huddersfield) and it not only gave great power but also amazing fuel economy when trundling along quietly.

Metric is for people who can't do fractions.

Atm im not after either as ive just spent 150quid on a 1300 metro head having it freshed up. BuT I do have a spare bottom end that I could play with when ive had me moneys worth out the setup I have. Something in between standard and k100 would be better suited to a every day car that on occasion can go absolutely bat shit crazy when needed.

I would look at the SC 7-port then. Depending on your budget.

The K head can be done on the cheap, but it is all relative. A cheap 16v is still going to cost a fair bit.

the SC 7 port is about the only conversion that is vertually bolt on, anything else will need a significant amount of engineering to fit...

£150 won't get you running with any of those above mentioned though

just found and read the whole thread on the 16v punto head, for the last 6 months ive been looking at fiat head gaskets thinking that they very close to mini, and ordered a gasket a few days ago to find out myself, should have goggled it first and found that thread!!!

did he ever finish the engine build?

It ran on propane, but since then robert has been doing other projects.
