Hi all.
Just wondering if anybody ever tried this conversion. Seems achievable as an alternative to the BMW k.
I only know of one running example.

The 8v looks an easier build. No cut outs, choice of cams.
The 16v had hydraulic lifters which limits cam choice and revs.

Not sure if it needs valve cuts on the pistons or if you can get away with dished pistons.

Ya pity not more photos available.
Looks like a fun project.

Am I right in a assuming if flat top pistons don't need cutouts on the Fiat engine they won't be needed on the a-series provided the heads not skimmed?

You can blame greedy photobucket owners for that one ... "Please host you photos for free here .. oh that costs us lots of money ... now pay us lots of wonga to keep them there (and we'll make it nigh on impossible to get them back)" ... think that's called blackmail in a court of law

There are a couple of details here on a SOHC Fiat head

@timmy.

 

Thank you for posting that link.   ...   It answers my prime question;   'all the head studs have to be moved'

And no actual pictures of the work on the head or the head bolts fitted. A lot of work to drill and cap all of the head bolts/studs in the block. Not your average DIY job but if its been done properly then its different.

much the same as with the K1100 head swap, although this would be easier as you dont have to convert a chain head to belt drive.

 

Ive looked at the fiat head and I'm sure it could be done keeping the centre front head stud in the same place.

Remove the other studs and try a Fiat head gasket to test your theory.

16 piston/ fiat block & head, circled is the oil feed to the head, it goes up the stud, this can be blocked and fed externally.  arrowed are oil drains back to the block, i would say only 2 are needed front and back, the rear ones sould be able to go straight down onto the cam follower gallery, the front ones might need a bit of consideration ( see the head gasket pic)
