im racing a 1600 zetec but i want more power , can i use cams from a 1800 or a 2000? also would the heads be interchangable?.
my other question is does the IB5 have a lsd?

 

Firstly, do you have a Zetec-E or a Zetec-S? No IB5 came with an LSD, dut they are available from Quaiffe and Gripper. Also the LSD from the BC gearbox of a RS turbo Escort will fit the IB5.

 

its the early silver top zetec, its in the fiesta mk3 si.
i dnt really need the lsd as im racing on grass.
i just got bike carbs but i dnt want to fit them just yet, i was thinking bout using injectors from the 1800 silver top, do u think this would give any benefits? thanks

 

Interchanging parts from other engines in the range will only lose you performance.
