Thanks for the sound info guys!

MDCOS - I just got the engine at a very good price, cheaper than getting uprated valve springs for the 2.0 Silver Top I now have sitting next to it

Simon - Cheers for the great info, guess my next question is what are the limits to these parts? At 291bhp was it still on standard valve springs? Has anyone pushed the standard rods etc...

Also did you uprate the rod bolts as I've heard they are uprated too?

Also very interesting info on the inlet, didnt know that. Guessing ill have to have an inlet made, is there no way of at least salvaging some of the zetec inlet? Cheers again!
