I've been told from my garage that they are different and that I'll have to change them when I convert my 1.4 to 1.8.Is this true?

how are you planning on converting your 1.4 to a 1.8 might i ask?

 

By changing the cylinder liners,pistons,crankshaft and ecu with the ones from a 1.8 engine

if i were you, id either just put a 1.8 lump in it. or get a 1.6 and change the crankshaft for a 1.8 one. would be much less work.
i take it your doing this for insurance reasons?!

 

I searched for a 1.8 lump but I found only one engine at my town and I'm really concerned for its reliability so I'm going for the engine coversion for many reasons,but mainly cause of the unknown past of the engine.

to answer your original question, iirc all the cams are the same. but i may be wrong.

 

A member of another forum told me sth that makes sense..they have to be different cause only the 1.8 non vvc puts out its power from low revs to 5500 revs whereas the 1.4 has power until 6200 revs so this could be due to the different cams.Isn't that logical?

the 1.8 non vvc will rev up to 6200rpm. same as the 1.4. however the extra stroke and gauge of the 1.8 over the 1.4 will give much more torque lower down the revs. same as the 1.6 does, and i know for deffinite that the 1.6 share the same head etc as the 1.8.
i truely think making a 1.4 a 1.8 is too big a step. maybe one engine size is enough?!

 

I believe that converting my car to 1.6 would be too much effort and little gains so I have decided to make it a 1.8 that has many potentials for advance and as standard is a quite powerful engine.

 

Is there any possibility that although the cams are the same,their timing is different and thats the reason why I have to change the cams as my garage suggested?

timing will be controlled by the aggressiveness of the cams. so if they are the same, then the opening/closing timing will be the same.
not been funny an all but, most of the members on this forum know a hell of a lot more than most if not all garages i can think off.

 

I would have thought the profile of cams on the 1.8 to be different as they have to cope with the longer stroke of the engine.

thats what i would have thought ashy. but people have asked on here whether 1.8 cams in a 1.4 will make it more powerful, and they said it would make little if no difference at all.
id dig the thread out but im currently putting my engine back together, if youd answer my thread id be greatful.

 

All 3 standard K16 engines, 1400,1600 and 1800 share the same camshafts.

The inlet cam is part number LGC106010 and the exhaust is LGC106950.

 

6800rpm..........
