Hi i was wondering how much speed and horsepower i would get if i put my 1.8litre audi turbo in my 126. I have planned to upgrade my halfshafts and gearbox to 5 speed synch abarth gearbox. All help appriciated

PS. do you have any else thougths of gaining hp without engineswap
 
I imagine a 1.8 turbo engine would have around 180bhp, it's speed would be very quick. Will it fit in a 126?.......no. Many tuning parts are available for the aircooled twin lump and 55bhp can be achieved - "big deal" I hear you say but remember, these cars only had 24bhp to begin with so doubling your power and fitting a close ratio gearbox will see you keeping up with most of the chavs. Don't forget most of the fun of a 126 is how it handles. If you want sheer speed the 126 isn't the best car for you.
 
the idea was to make it my daily driver so it would go 140'ish so i wouldn't block the highway. and now that you say it makes sense that the car is more reliable without the turbo since the engine is from 70's and desinged without turbo and for 24hp. i really love driving the car since its like go cart becuase its so small thats whty i want to make it a daily driver.
 
An Audi 1.8t is probably not the most obvious choice (though I doubt if that ever stoppen ons of you finish guys), I think it is too big ander long for the 126.
More common engine swaps are:
- fiat fire engine: cheap, good reliability and standard power up to 100hp NA or 150hp TA
- alfa boxer: cheap, fragile, good fitting (bonnet will close with minor body modifications), standard power up to 135hp NA (noy very suitable for turbo)
- Subaru boxers, suitable up tot above 400hp TA …
- andere a lot more…

There is quite some information available in the 126 andere 500(classic) section about engine tuning or swaps
 
Sorry, I did not read your post entirely correct.
The turbo of the Audi 1.8 will definitely be too big for the engine, resulting in a huge turbo-lag and less power then you would be aiming at.
If you would want to turbo this engine, you need a very small one, fitting the power you would realisticly be aiming at, possibly a turbo from a small turbodiesel or such.
