I worked out around 8 grand for me. To an already nice mini (no paint or body work, just toyota mod)
But it all went to crap when I found out I can't get a motor with ECU. Well I can but it's 150,000kms and $2450 (front cut) or $3600 with a spare motor (no ecu) of unknown milage, which is very expensive compared to what other's in SA have paid for thier engines.
Subframe I can get done for a grand, but still need engineering. Plus guages, drive shafts, radiator and everything else it adds up.
And if I worked out that it would cost 8 grand that probably means 10.
It's worth it if you intend to keep the car, I don't think i'm willing to go into this (which I had planned too), instead I'm looking at other unfinished projects of other cars around the place.
The best setup I've see is the K series Vtec from USA, only problem is it makes your front track wider, not sure about engineering that.

. K series is highly powered, but I think they are expensive and they only come in 2 or 2.2 litre (too big!). BUt the kit (althought fairly expensive, $2500US) comes with chromoly drive shafts, the kit has many hidden cost.
Overall, kenno, I reckon your doing good. Although I've seen a Qik Brix racing subby for a suzuki swift gti motor and thought it looked dodgy, but that might be an old version or the starlet one might be tons better.
