Default 1242cc Fiat 16 valve (Punto Sporting) in round nose.

Hi,my plan is to put a Fiat 1242cc 16v engine into my round nose 89 Mini.
I had planned to do a "fast 1000" A Series build but kept coming to the conclusion that it was going to cost me in excess of 1300 and would still be a pain on motorways even with the planned 3.2:1 Metro turbo diff,so I started looking for sub 1400 16v modern engines with 5 speed (maybe 6 speed ) gearboxes and decided on the Fiat.
Ive already made a jig for the subframe to support the front rail and retain the tie rods and front panel mounting points when I start cutting it up.
The subframe design will follow the one from the Irish Mini Forum and be of plate rather box construction.

Best of luck with it. It's good to see some different conversion builds.

Yeah that was the only similar build thread i could find on here,
I had a bit of luck yesterday as a friend of a friend had a dead 5 speed Punto gearbox that was going free (he was fed up tripping over it) so I grabbed it to use for positioning and mocking up mounts ect.
And today I've collected the folded 3mm steel plate steel I'm going to use for the subframe side rails, I had them folded by a local fabrication company who's owner is a fellow Modded Mini fan having done MG Metro Turbo and Golf 1.8GTi conversions for himself and he's currently doing a Cosworth 4x4 in a heavily modded Mini round nose.

The reason for going to Fiat power is that there are loads around,they were fitted to Mk1+2 Punto's ,Brava's and current 500's and Punto Grande's.
I realise they have they're faults but then so do most engines,gearbox wise they are cable change and mostly hydraulic clutches and any 1242 box will fit but I'll be trying to get a Sceicento 1108 Mpi/Spi (Not Sporting) box as these had 3.5:1 diffs.
For starters it will be kept as standard as possible (with the exception of the exhaust manifold) but if it proves a reliable conversion then may be I'll think about going down the tuning road but for now 80-85 bhp will do.

Ahh Birdman......a man after my own heart.
I looked into that but decided to start simple.

Are those slabs of steel the Jig? If not they would be a little too heavy for the actual frame me thinks.

had a 1.2 16v brava for a while, and all i could think was how awesome an engine it would be in a mini, very revvy, and pretty gutsy down low too. looking forward to it!

No Birdman,the steel slabs are the support jig for the sub frame,they were temporary packing weights that were fitted to an electrical control panel that I installed at work and were too good to throw away.

This what i'm hoping my subframe will resemble, its a design used in a Irish Mini rally car from the Irish Minis Forum at http://www.irishminis.ie/forum/viewtopic.php?f=6&t=3452



I really like the simplicity of it and the fact that it still looks like a Mini subframe which should'nt get the MOT man too hot under the collar.
