Looking in too this for a mk1 focus.

What are the differences between the 1.8 and 2.0?

2.0 engines are going silly cheap on ebay, and its tempting!

Is it anything more than just an ECU, bottom end and head?

 

i wud be interested in this too!!

Free bump!!

 

what do you mean ???

18 is 105bhp and 2.0 130 loom is the same just need change ecu. also gearbox aswell as 2.0box is very very good

 

is this for the blacktop zetec? I no you can swap silvertop stuff like cams/ecu/tb for instant gains?

Would changing the ECU from 2.0 focus make much difference with other mods (exhaust/cams etc)?

 

for the focus mk1 with black top zetec e engine

1.8 is 115bhp and 2l is 130bhp. cams are same, dont think the heads are quite the same.

you can swap the whole engine over piss easy along with ecu but the 2l's do run the stronger mtx75 gear box whereas the 1.8 runs the ib5.

you can prob run either box on the 2l but not 100% sure and you'd have to check on what clutch to use.

 

iv kind of decided against this now as if i buy a 2nd hand engine i wont know the condition of it unless i rebuild/buy new and the costs wont be worth it for 15bhp.My cams are uprated now on mine. Just wondered if swapping ecu to 2.0 one wud make any difference as i think ford said they are different?!Matt

 

has anyone done a 1.6 to 1.8 conversion? im loking at buying a s reg 1.8 complete car to put the engine etc in a 1.6 on a 52 plate. anyine done this and know whats involved?

 

i just taken 2.0l out off mine wich is for sale as am stinking an rs lump in

 

Absolute pain in the arse job and massively not worth the effort!

Even a 1.6 - 2.0 litre conversion isn't worth it for the effort.

EVERYTHING has to come out of the 1.6 to fit the larger engine and all the required parts - seeing as they are fitted the opposite way to each other!

Woolford - You're talking about Silvertop engines, completely different to Blacktops from the Focus.

G T M - 1.8 to 2.0 litre isn't 'that' difficult to do depending on how much you want to change. The blocks are different (obviously) and the cylinder heads are only different due to the larger combustion area in the 2.0 litre head. The camshafts are exactly the same in both engine, the mounting points for both engines are the same and the 2.0 litre engine can be made to run with the 1.8's IB5 gearbox and shafts if you use the 1.8 flywheels and clutch. As for the ECU - I'm not sure if it will have enough tolerance in its running parameters to 'self-learn' to cope with the larger engine and air/fuel delivery but I'm planning on finding out later this year. Don't just swap the ECU's over - the PATS system and PCM/GEM systems are built into them so not only will you need new keys and transponders for the immobiliser you will also over-fuel the engine as the 2.0 litre ECU will be expecting to use 2.0 injectors which are either bigger or will be kept open for longer (can't remember right now if they are the same as 1.8 ones or not - either way it won't work).

 

i thought the 1.8 and 2.0 zetec cams are different, but the injectors are the same?
