hello
i have recently put a 1.6 engine into my focus as i blew the 1.4 engine up lol
however its still slow and i was wondering how i can improve the performance of the engine without spending a lot of money. does the 1.7 puma inlet manifold fit this and make much difference? i was also wondering about changing injectors and the throttle body to a bigger one off a 2 litre or something? can someone help?
thanks
