when doing a 2.0l or 1.8 ZVH, do you need uprated fueling to conpensate??
i think you do myself, but whats the best way to do it on a buget?

the only 2 ways i know of are 5th injector or cossie management.

is there other ways round it?

iv recently 2.0zvh-ed my S2, and it defo does need more fuel iv been looking at 5th injector systems and it is the cheaper option but i belive if your going big in the future tis better to go stright to cossie mangament. iv not done either yet but im not driving my car until i have done it. heard an uprated fuel pump wont hurt niether.

cheers, im only going 200 bhp on mine, not big power at all, and i think im going to go for a 1.8 zetec now, as i can get a 1.8 cheap, plus i know the history of it, which is piece of mind to me.

so hopefully my fueling wont need to be changed to much to cope

320 bhp

YOU NEED COSSIE MANAGMENT IM RUNNING A 2L ZVH WAS 224BHP WITH ENRICHMENT MOD ON METERING HEAD BY PTS AND A COSSIE FUEL PUMP STILL MELTED A PISTON THATS WHY IM GOING THE COSSIE MANAGMENT ROUTE WORTH IT IN THE LONG RUN

ye cossie or an aftermarket management all the way.

fuel pumps on standard RS's don't need uprating unless you just want a cossie one on your spec sheet, original ones work fine.

well i need help as well, how much is cossi managmnet gonna set me back? tried asking in the general room but some sarcastic traffic warden was most unhelpful and told me to "do my OWN reserach" thats what im doing by asking people on here isnt it? any one who can help me with this issue will be most appreciated as i dont know much about cossie managment.

cheers
