I know someone who was looking into either lowering the compression or running very low boost, for a 30-40bhp gain on his 210bhp Tipo.
Far better, in the long run, to keep the original masterpiece of an engine it has, and the turbo system should be OK on (some of) the Uno Turbo's management system.
At a guess, I'd say lowering the compression by 10-15% by getting a custom spacer made up, and running a T3 Turbo at 1.0Bar with a Mig welded flange on the manifold should do well, and make a standard Tipo run at 260bhp+
More than that would entail a 5th injector and other fuel management system bits to be installed.
Low comp turbo @ .5bar should do for a "My First Turbo"
One thing to think about, though... which is awesome...
Uno Turbos can be run stably at 200bhp after a good few grand is spent on the lump, but they have been known to get upto 240bhp and still be fairly manageable on a road. That's on the 1.3L.
On the same bhp/litre, it's 306bhp or 368, respectively. Imagine that in a Tipo...
It's enough to get me thinking about copping a sedic' for myself >=)...
and even at low compression, you'd still have enough power to get around pretty quickly at a hugely low boost, if you wanted a standard engine.
The Uno Turbo's always been more of a turbo powered engine to me, whereas a turbo should assist an engine. No objections, it's a hell of a lot of fun, but you get the feeling that, weighing 50-60kg over a normal 1301cc Uno, it'd be a bit of a slug without the turbo attached.
