I´ll do my best, it´ll just take a little time, as my hard drive collapsed
a couple of weeks ago and I lost all my files.

Restrictive? IMHO that is BS ;-) It is better than 3B´s one. Maybe it´s not 
the best possible, but good enough till ++300Hp. Only problem is that,
the throttle should be in the middle of the manifold, runners are ok.If You
are going to have an extra injection, the throttle should be moved, or most
of the added fuel will be in the cyl #5. ( or put 5 extra injectors in the runners :))

I´m aiming ~300 with my MC-2, now some 250. Because I won´t keep that 
car more than 2 yrs, almost everything will be done with almost stock or 
modified parts. So it is easy to get back to the stock form. ( = read cheaper,
for poor me :)) I just tried to take part of the lists 10vT-discussion, but because
of the ignorance I did quit ( not the list, just the discussion ).

I´m gonna keep OE I/M and that OE 2-piece exhaust header, the charger 
will be chanced. The original cat is the first to be moved, that´ll happen next
weekend. I´ve been so busy with my other activities, this car has been chancing
very slowly. Allready it is much faster than my former ( and loved ) stock 20v 
CQ in the track and much, much faster in the straights ;-)))

hmmm....IMHO sure it helps, but do not wait too much for it...

me neither, but my next project will have a one...If my family don´t again
need new clothes ;-))))
