Engine conversion.
Hi I'm sorta new here lol but ye basicly I have a 51 plate 1.6 focus its had a miltek exhaust system fitted inc manifold and a k&n panel filter fitted I've had every engine focus bare the st and the rs but this is quick I've had 140 (private road off corse ) but now the millage has hit 130 thou so the bottom end has started to knock so was thinking about changing the engine to a 2.0l but apart from the obvious engine ecu key exhaust and engine wireing loom what else would I have to change ? Thanks in advance jake
Engine/engine mounts
engine loom/ecu/key/pats sensor you may not need to change the engine loom but will definatley need the ecu and pats sensor/key
clutch
gearbox can use one you have but gearing will be different
exhaust
suspension
brakes

1.6 and 140? if so 
oh and just by a 2.0 rather than bother with a point less engine conversion , time and insurance costs, over just buying one ain't worth the hassle.

bud starter motor bolts to the gearbox so 2ltr gearbox must have it located on the other side! there for if you keep you box use 1.6 starter ifyou use 2ltr you will need 2ltr starter however as Fil said its not worth time hassle money etc cheaper easier to just buy a 2ltr

All I no is the cars had the milteck exhaust system and k&n panel filter not sure if its had remap or anything but speedo is correct as my friends Subaru was next to us because he didn't believe it till he sin it
Also bud not to rain on your parade but my FRS which was a 1.8lx 4dr too start off when it had original 1.8 lx running gear in before I converted it had, K&N 57i kit,Cams and veniers, double valve springs and head work(ported and polished) bigger leads,tubular manifold,s/s exhaust 3" and a few other bits and it pissed over st170's but after 100 they would pull on me and it only did an accurate 134mph flat out(no I never wasted time or money doing this car I got it this way to convert too FRS) so you speedo may have showed 140 but car certainly didnt do that speed!

bud your 1.6 gearbox would struggle to get you to that speed with a 1.6 engine its not geared for high speed also the zetec is at its best at high revs but not in basically standard form
Yeye well call me what ever the eff you like ! (Y) I know what my car does so crack on not believing me i simply posted to get sum advice not to get slated cuz dont believe me (y) sad sad people !
Also bud I also dont think you realise about ALL FORDS they are not great with calibration and are almost always at least 10mph out once you reach 100mph so if it says 140=130,150=140 etc etc

Lol can I buy the engine? If its that quick get it repaired as it will be quicker than replacing it and what was up with your mates scobby? As it should eat a 1.6 focus!
I don't claim it to get there as fast as you saffy does ! But it gets there I've got no friggin reason to lie I've raced a remapped fabia vrs and stayed on the arse end off it it couldn't pull away from me
As above Im a FORD nut but my old seat leon cupra R with remap tb.04 turbo,manifold,exhaust injectors, k&n would of eaten a focus in any form let alone a 1.6 and its same engine as golf gti turbo and skoda vrs fabia vrs all VAG engines

The reason people dont beleive you is because the 1.6 Focus produces 98bhp and has a top speed of 115mph... Sadly mate your filter and exahust at best will give it 5-10bhp more which is no where near enough to get to 140mph.
But that aside, to answer your question I also think it would be much easier and maybe even cheaper to just buy a 2.0 Focus than to retro fit the engine, ECU, etc..

My Fiesta had a full Milltek and a panel filter, it'd show 140mph on the Speedo, down a big fucking hill, but you were doing about 125 if you were lucky. Your 1.6 Focus does not do 140mph, they're not even geared to that at the limiter, but it wouldn't pull to the limiter in 5th anyway!
