I'm new here so forgive me if this has been covered before.
I am looking into the purchase of a 914. I would prefer a 70 or 71 because they weigh the least. I am 6' 4" and would require some modifications to the seat & shifter to drive one comfortably, but I think this is doable.
The question I can not seem to find answered (I used search) is if the 1.7 engine in the 70/71 can be built up to 2.0 liters or more to make a reliable 100 or more HP/torque number? If not is it easy to retrofit a later model 2.0 into the early chassis? I am not really interested in a 914/6 conversion as I would like to keep to the original design as much as possible, just a little bump in power (torque mostly).
