hi guys i am concidering putting an xr2i engine in my mk4 fiesta as i can get it for a good price but i would like to tune it upto rs1800 spec at least. how much would i be looking at roughly?

i have found an ecu on ebay for the rs1800 how much would you pay for one tops?

I think you just need cams, ecu and air flow meter.

I don't know if you'll have the same problems that I did, but when I put the 130psi lump into my si, it wouldnt start because of the pats imobiliser system. It would run with my original ecu but then as soon as I put the rs1800 ecu in it wouldnt want to know. Might be something to look out for when putting into your mk 4

Noticed u have a mk4
