mk4 astra... and want more power (i.e engine conversion)
my question is, what is my best option in terms of cost, performance, and difficulties with fitment?
in my mind at the moment its a toss up between Z20LET, C20LET, X25XE
i also have a vectra v6 which is currently off the road and i need to get rid of, so i affectively have an x25xe sitting there doing nothing atm
opinions and advice please?
sorry if this is in the wrong section btw
