im considering buying these off a friend for my c14se. What i want to know is what sort of cost am i looking at to make full use of these. The engine was rebuilt 3000miles ago. I would also like to know what sort of power i'll be able to get from them. I have 89bhp at the mo but the timing needs adjusting so there ahould be about 93bhp in it. Is it worth my time/effort/money or not really. I appreciate that i could get more power as standard from a c16xe but im doing my best to be different at the mo!
