I have a K11 1.0 Tempest and would like to increase the performance to make it a fast road going car. I would like to help from the very knowledgeable folk on this site to make suggestions as to how I can go about this. For example could I improve the performance by making mods to the existing engine or would it be better to replace it with a larger one, if so what do you suggest, also tips on suspension, braking etc would be gratefully received. Look forward to your replies
