My Focus 1.8 16v zetec has 106k on it

Burns no oil
Doesnt use water

Has a full mongoose system on it and a K=n with the recent addition of 18 inch wheels

I have owned it 4 weeks

Runs spot on

I have some cams to go in it. Kent stage 1

Can I just go ahead an fit them an its job done. Will reset the timing aswell.

I will be getting a remap in the coming months aswell to cmpliment this

What gains will i see with just cams?

Will it be noticeable?

Will it kill my engine.

Bearing in mind i have just done all the belts and a full service

Thanks in advance
