Hi guys
I will not bang on too much about the track day I had with a few 914 pals at abingdon airfield in Oxfordshire last Friday, although it was great to meet new people and new cars , I sadly limped home in my 1.8!!!! Fan belt came off damaging the fan and now the engine has to come out. I have been thinking of a big bore kit for a while and I know I have options.
I am aware I could go for @ 96mm slip in which will take me up to 1911cc , or 2056 with a 2 litre crank. Am I correct?

Or I could put a 78.4 mm crank in which would take me to 2270 cc , now that is more like it. I do have twin dellortos on the car which is good and I am aware I would need to re-jet those, no prob.

Is there anything else I would have to do ? Would this be a reliable conversion? Would I need to change cam?

I am keen to do this and do it correctly without having to sell my mother to fund it!!!

Look forward to your very welcome advice.

Hope you are all enjoying your 914s

David
