Out of curiosity, has your brother's 243bhp Punto GT been on a rolling road to show those figures? Any print outs/ graphs we can see? What mods were done to it to get to 243bhp? That's a lot of power, even from a 1.4 turbo engine (unless it has had a bigger engine fitted), and it surely can't be very driveable for daily use? Has it done any official drag runs with recorded ET's/ terminal speeds? More detailed info. please!
Regarding your intended project, you can help us to help you by answering a few questions:
1. How much money do you have to spend on this project?
2. What projects of this scale have you done previously?
3. Which engine are you going to use?
4. If you use an engine like the 1.8 Tempra, what modifications are you expecting to do for it to make 240bhp?
5. What engine management system will you be using for the engine?
6. What modifications are you going to do to the Uno 45's suspension? Are you going to do anything to the chassis to beef it up?
7. What are you going to do to upgrade the brakes?
8. What facilities/ equipment do you have available to you to carry out the work? Can you weld and fabricate parts?
If you can answer these for us we can then all use our collective knowledge to give you advice and get this project off the ground.

1. whatever it takes. project will be done over 3 or 4 years thus spreading out the cost. i dont know how much i will need to spend because i havnt chose an engine yet, but i would expect it to be in or abouts 12-13k.
2. the previous said gt. the first track/race car i was envolved in building were 3 unos for the irish uno championship, following that were the puntos and then the hgt,s. several lap records were set in mondello kirkstown etc... the most recent achievment was winning the punto abarth championship this year ( my father not me ).
3. i think its clear im not sure what engine im using, im still tossing around ideas in m head.
4. much the same modifications as listed above.
5. stand alone custom managment system....
6. chassis will be seam welded, contemplating roll cage. fully camber/castor adj coilovers, arb's strut brace, stronger polyeurethene bushes if needed etc...
7. havnt given much thought to the brakes yet but i know the non turbo coupe brakes fit wit a little pursuasion, that might not be enough as of yet i dont know but obviously the stopping power would need to be greatly improved
8. i have a main fiat/ citroen dealership at my disposal (that would give you an idea of the equipment i have available to me) but is mostly fairly busy, i will be building it in my grandparents garage with much the same equipment, it was a fiat/lancia dealership until they retired. has since been closed for buisness. my father tought me to weld when i was 10 or 11 i think, fabricating has become kind of a hobby for me since.
