Ok, maybe a dumb question. But.... Went to look at another 914 for a friend. The badge on the rear says its a 1.8 But when I looked underneath to peek at the pans I noticed the heat exchangers were definitely 2.0 The ends where they attach to the exhaust/muffler were short and mostly straight. Which to me indicated 2.0 not 1.7/1.8 which I thought had more of a longer run of pipe that has a definite rise to them before the exhaust flange. Am I wrong to think this car might actually have a 2.0? Will the 2.0 heat exchangers even align with the 2.0 heads? Couldnt get into the engine bay to look as it was at a small dealer that was closed for the evening.

All heat exchangers fit on,any motor.

The big different would be the case number, and the three bolt intake bolts or four.

Check the spark plug locations, the 2.0 heads are different than the 1.8

2.0 exchangers need a 2.0 muffler and a 2.0 muffler hanger too. regardless of engine used on.

1.7 and 1.8 plugs are on top of the engine tin. 2.0 is on the side.

Count the nuts that hold the intake manifolds on the head.
4 bolts -> 1.7 or 1.8
3 bolts -> 2.0
