Hello!
I'm Antonio frome Rome; I've bought a nice 914 1.7 litre.
So I started this tuning project.
The basis is to start with the
DPR 66mm counterweight crank (55mm bearing)
I think is better have large rod bearing for turbo modification.
And with turbo is not so important have big displacement.
So in the reason of this I have some question.....
1- Chose of the piston and barrel; I think to use the 98 mm je piston and biral barrel
from AA performance, they build this kit for long stroke crank 78/86 mm.
So to fit correctly the piston which length of rod I'need? Could you advise me if
exist one with 55 mm bearing for typ 4 engine with adeguate lenght?
2- Is really recommended to not go over 98 mm bore? with 103mm bore the case
could crack? I'do not have experience on typ 4 to say which is the limit.
Hope everyone can advise me the better chose....
