156 2.0 16v engine

[cabs]

Hi, can anyone tell me if the 2.0 16v engine in the 156 is the same as the one from a late 2.0 16v 155? thanks.

I think it is...if it's the one with the silver cover on then yes.
My 164 has the older engine with the timing chain rather than belt, and no silver plastic cover. I'm sure the 155 had the newer engine.

It's the same basic engine but I don't think it is quite the same version if that makes sense.
The 155's had alloy cam covers - as did the early 145QVs.
The 156's have always had plastic silver cam covers as far as I know, which is a different engine management set up.

i'm pretty sure you are correct

155s alloy covers
145QVs alloy covers upto ~1999, plastic after
156s plastic covers

One point here the early 155 had the 8 valve TS engine same as the 75
this changed when they went wide body to the modular 16 valve
Fiat lump. But both are referred to as twin sparks!

Yes!!
The 8 valve was all alloy and chain driven and quite different from the 16 valves.

Cheers chaps. But do you think it will be a direct swap into a 156? Can I ask what the difference is between the management systems? Will this matter if you are just changing the engine over?

[minimods]

It certainly won't be a straight swap. The later engine has a completely different ECU and wiring loom. It would be a nightmare to do unless you just changed the block and the head, and used the later inlet and gubbins.

I am guessing the 156 engine is shot? Cambelt failure?

[cabs]

I am selling my 155 engine at the moment and someone asked if would fit a 156. If they just swapped the bare engine it would go straight in then?

[Alfa Mad]

I'd advise against- just too much work. When I had a 155 with cam belt failure (not mine), I got a 156 head and swapped the valves etc over. It was still expensive.
You could probably do it, but wou'd need to change all the engine sensors and manifolds over. You'd have to block th ports for the EGR system also. I can't say for sure if it is easily possible, but I'd look out for a 155, or 145/146 Euro 1 instead (without the variable inlet tract length).
