    I had considered than in my GT when I had it  see  
web.csuchico.edu/~javad  to see the car.  To do it right, you would swap the 
associated electronics over including the knock sensing ignition.  Maybe some 
listers have some experience with swapping over only the knock sensor?  An 
easier way to do it would be to swap the lower end of the NG motor, and 
minimally run only high octane gas in it (10:1 is high, but VW guys run it 
all the time in old A1 GTI witout too much trouble).  You could also add a 
J&S knock sensor to ensure knocking is not a problem.  
    IMO, if I were to do the work to swap all the wiring and ECU for about 15 
hp, it is not worth it- an MC is going in for that much work.  If more power 
is what your looking after, look to a turbo conversion.  The NG is not going 
to make the car much faster, 
with an MC you are looking at 220 hp potentially, vs 130.
    As for the brake conversion, see the web site...good luck!
