2.5 Short Stroke Project
Dear all,
I am a new member and a great fan of early 911, specially the special models ie. R, T/R, S/T, RS and RSR.
I have got a 1971 911 S which I am converting into a 2.5 Short Stroke, currently I am using the following parts:
Original engine case
89 mm Mahle P&C
2.7 RS pump
S cams or Sprint cams
R exhaust
I am also replacing the following parts with fiber.
Front & rear bumpers
Hood & engine lid
front wings & Rear fenders
and would really appreciate if you could help me with the following, taking into account that I would be using the car for twisty velocity rallies, hill climbs and occasionally circuit racing:
Which cams do you think are better S or RSR?
According to the figures of the 2.5 ST it had 41mm of I/E, is it too much?
Regarding the parts I am replacing in the front of the car with fiber. I was thinking of reinforcing the chassis by making a cross in the fuel compartment like the 935s. have any of you experience lack of rigidity or feel in the front of the car after replacing the front part of the car with fiber?
Many thanks in advance for any advice
PS. Wayne, great book, it has been my guiding light.
