I am about to pull the 2.3L motor out of my 86 190e w\5speed with about 170k on it. I bought an 88 190e w\auto car with 105k 2.3L that runs like a clock and no noises, for a donor and to canabilize.

My question is there appears to be differences between the two engines. Single and dual row timing chains, probably two different flywheels etc.

Mechanically, what engine parts are not interchangeable? Besides changing flywheels to take advantage of the 5 speed setup, do I have to change the oil pan and pickup tube? Can I use the 86 dual exhaust manifold on the 88 motor, the intake\KE-Jetronic setup from the 86? What year clutch assembly should I order?

What other nuances can I expect? I want to set this car up to squeeze as much economy out of it, within reason.

In another forum, it was mentioned that I should pull all of the ignition parts & engine wiring harness from the 88 tho make this fly.

Any other tips or experiences that I can glean from readers would greatly be appreciated. I want to set this car up to maximize its economy, within reason. I am at the point of buying gaskets, clutch package and the necessary new parts to make this swap work.

The 86 190e is one of the best designed and balanced cars I've ever had. As a hobby car I am willing to spend the time to do it right
