A 1.2 16v Brava will probably be the cheapest doner car as the "Boy Racers" prize the Punto Sporting highly.

I've got to do the rear radius arms tomorrow as part of my pre Le Mans 24hr Mini service and we're off to Crystal Palace on Sunday for the classic sprint so will not be working on the subframe this weekend.

Ive done a bit more web searching and have uncovered some more info about fiat 1242 engines...
1, The 16 valve engine has steel main bearing and big end caps.
2, All 1242 16v and 8 v engines are'nt balanced very well as standard but when they are dynamicaly balanced the standard bottom end is safe till 8500rpm.
3 The 16v head uses hydraulic tappets which cannot be upgraded to solid tappets so this limits the cam choice to "fast road" spec to avoid pump up.

Sorry I had to go out....
4, The mk1 Punto 75 had a 1242 8v engine with a one off "big port" cylinder head that had the ports raised to allow a straighter flow to the valves and a special camshaft to get the power up from the standard spec 60 to 75 and also has the steel bearing caps from the 16v.
5, The 16v has slimmer and lighter conrods.
6, All 8v engines can be retro fitted with an Uno distributor.

So it may be a case of going down the 8v route for ultimate power if thats your thing or sticking to a lightly modded 16v so that you can wear the 16v badge with pride.

I made a start on the subframe mods today...........


All chopped out and ready to go


Geabox in place to see whats what,it'll be a tight fit but should be OK


New section cut,folded and welded into place


More welding


Top view



Top view of gearbox,still needs to go back and across a bit but will need some some gentle hammer thrashing/cutting & welding on the rear of the subframe.

Thanks for the encouraging comments chaps,this thread will be on hold for a couple of weeks as I'm to the Le Mans 24hr race tommorow and won't be working on it again until the 23rd.

Right I'm back from Le Mans and raring to get going again on the Fiat conversion.
I'll be moving this from the Chat to the Builds listing to keep the mods happy.

Hi again, its been a while and things have changed but my Punto powered Mini project is back on.
After being Miniless for over a year I will shortly be collecting a bare mini shell into which the Punto engine will go.

We (my son Lewis and me)made a start on the new shell today.
I got Lewis to make a tool to accurately mark the inner arch profile on the rear wing then I cut out the marked shape to allow me tub the rear arches.
Then Lewis made a start stripping the front and rear subframes.

Hi mate, glad to see you're cracking on what are you thinking of using ECU wise? I fiddled with the original Punto ECU on mine for a while but couldn't get round the immobiliser that cuts off the fuel relay
Mines the Punto conversion on The Mini Forum you commented on. How'd you get on with the Panda gear linkage cables too?
