you are credited with this one: So over this summer, I refreshed the suspension and brakes that are going on the -6. I’ve had a set of front suspension with delrin bushings, 21mm torsion bars, big aluminum calipers and -6 rear trailing arms with delrin bushings. It’s all repainted and ready to go in. A mild heart attack at the end of September and a triple bypass 6 days later postponed a bunch of work. I’m getting back to it cleaning parts for the winter project of building a motor. I’m looking for motor advice. I want a small displacement screamer. We don’t have freeways on the Maine coast and it’s not going to be a daily driver just a toy that I will never sell. So, I am building this on a 914-6 case, not the original which I have, counter weighted crank with matching rods, 69S heads, 81 mm 906 pistons and cylinders with 40mm Webers. Which cams? I am looking for a willing motor with explosive ( for a small motor) revs from 4500rpm up to 7500. What does the group say? Our old track 911sc was a 3.2 with ge80 cams which did that but I don’t want that kind of power for a street car. What does the group say? 911s, mod S, 906, Dc60? |

You have already gotten some very good and knowledgeable input……I am going to add mine because I was looking for similar end result. Your 4500 rpm up is interesting but not very good for the street…..as Mark said. I went with 69S Mahles ( old school mfg) .
Had head work done on original six heads ( now have 46/40 valves). If I had to do it over I may change to 2.2 heads ( I think) as the valve angle is better than the 2 liter heads and improves combustion pattern. This came from Post build research. I went with Dougherty DC 30 ( I believe those are referred to as modified solex or close) S cams too high rpm curve, E runs out of gas too soon……based on my info. Not sure this is necessary but went with an early Bosch distributor. Engine is done but car is far behind so can’t provide actual feedback. I’m going with stock bushings and stock front bar with 100 lb rear ….90 is stock. The 100s are shorter so drops ride height a bit. 125 or more too harsh for my goals. Sounds like fun car. |
