Hi everyone, just wondering does anyone know if its possible to fit a 2.0 zetec
into a mk3 1.8i 16v fiesta xr2i? and what kind of work would be involved
cheers folks

 

yer mate you would need to just swap the block and the sump and water pump off your 1.8

 

Can you not just drop the 2.0 straight in

 

nope

 

Surely you've got the bits from the 1.8 still? If not, they're quite easy to source.

Think you'd need the ECU from the 2.0 too.

Other way is to upgrade to rs1800 spec? Don't think there was much difference other than cams, ecu and i think there was something else.

 

yeah i'm running it right now, i'm just trying to work out what all i need and see if it's worth doing, thanks for your help guys

 

Inlet manifold, which is also recommended for the 2.0 conversion too

 

as above pal swap your sump,and water pump over to your 2.0l

 

dont need a 2ltr ecu at all for it to run, you do need the 1.8ltr sump and oil pick up as the sump bowl is on a different side to accomodate the front pipe, the water pump flows in a different direction on the 1.8 which is why you need to change this too, also keep your original inlet and get an rs1800 throttle body as they`re bigger, if you do fit an rs1800 ecu make sure its correct as the earlier rs 1800 and 2i had similar ecu description one is 2fdc the other 2fcd cant remember which is which, when you fit these you need to rev the engine at 2,500 rpm for around 20 min for it to program itself to suit the engine, you will hear the revs alter several times even though your foot will be in the same position,if you just plug in the ecu and run it,it will be ok til around 3,000rpm then it will feel like its holding back,its well worth doing as i had a 2ltr 2i a couple of years ago and it was so much quicker than standard, especially midrange, you could also dump the exhaust manifold if it has the egr pipes on it as they poke quite far into the exhaust ports restricting gas flow, can find a non egr manifold on some escort 1.8si`s but not all hope this helps,roy
