Hi again yeah I was searching the Internet about alternatives and found a 1.8 litre zetec http://www.nettivaraosa.com/viewPart.php?id_part=862657 I believe it's a silvertop not sure and from my understanding this is the one that most people go for.it is for sale for 300 euro I guess that's about 280 quid is this a reasonable price (the thing at the bottom has a lot of rust though). I think this is best bet and understand they are quite easy to get extra hp out of.
