Wow lots of emotional reactivity here, ok I am done playing dr phil. But seriously guys calling people dimwits kinda pisses them off when they are getting advice from people who actually tune zetecs for a living. The car ran ok with the suck through system but it runs much better with the blow through setup. What pisses me off is that one group of "experts" say to do it one way and another group of "experts" claims another. Give me some credit I did the first 5 speed swap when everyone said it couldn't be done without swappping the subframe, I did the first focus engine swap, and I did the first home brew turbo setup on a zetec in a contour in the US. So I may not be an expert but I know my stuff. Also anyone who knows anything about dsm eclipse turbos knows that a blow through setup is what the high horsepower dsm cars use. Thank you everyone for the information you have provided but my engine has not gone boom yet and won't because I don't let it run lean or over 5 psi.
