hi i got a fiesta si mk3 withe 2.0l mondeo engine fitted and wondering which cams should i fit kent cams or piper cams??? and will i need to chip it or remap it to make it run ok or will the standed 2.0l injeters work fine?? HELP PLEASE!!!!!!

 

The standard 2.0 ltr cams are good for 170 bhp. Your inlet manifold can only flow enough air for approx 150 bhp. You do not need new cams!!!!!

Your next step is aftermarket management. Then you need to look at a better inlet and only then shoudl you consider new cams.

 

i only got the 1.6 zetec manifold on at the mo but 2.0l thouttle body on it with 2.0l injeters runs fine but wot manif old should i fit on it to make it faster or should i port and polish the 1.6 bigger??? help please

 

The best inlet is the RS1800 one. Your injectors will be fine but you need the 2.0ltr MAF and ECU.

 

has the fiesta rs1800 inlet manifold got begger port than u 1.6 zetec si ports on manifold????iv got 2.0l maf and ecu on it now
just 1.6 manifold but the port seem small is rs begger than??

 

Yes, the RS1800 manifold has the biggest ports available.
