Capri Technical Forum:

I have changed the worn 137000 mile engine on my 1986 1.6 laser, for a unit from a low mileage 1985 sierra 1.6 E-max. I have found the cylinder head to be identical, but the block is 10mm higher. It must have a longer stroke, as "164" is cast into it (I presume this is its cubic capacity) with the Capri unit have just "16" cast to the right side of the block. I was unaware of this until it was fitted to the car and the Capri cam-belt and cover, would not fit. I initially panicked, thinking the air filter casing would rub against the bonnet, but it turned out to have adequate clearance. The only problem I now face is the front section of the exhaust pipe is touching to the bracket that supports the gearbox, due to the manifold sitting 10mm higher. The only two solutions I can think of are: removing the exhaust pipe and modify a bend using heat, or sourcing part to use as a spacer, between the manifold and down pipe and clamping together using longer bolts? Does anyone have any advice or thoughts to share?

Based on the block being taller, I would say its all 2 litre dimensions.

Check out a 2 litre down pipe or manifold.
