Good project, should be kinda easy to set up once you have the spark sorted,
The old quattros had 200bhp on K-jet so should be very feesable.
I was in a Mk2 16v golf with a tuned k-jet TSR 1800 lump, chap said it dynoed at nearly 170hp and a few runs around a track I believed him
I love my k-jet, its so feking reliable, after I removed the ISV she behaves what ever the weather.
I don't see why it it should be a gas guzler either, all you would need it a adjustable fuel (control) pressure regulator so you can set it to run daily sensible power or weekend toy
Ps, get some pic's up !
