E36 Coupe 318 or 318is?
Discussion
Hi all.
I have just aquired a 94 3series coupe with a knackered engine. I havent picked up the car yet so im unsure of what engine it has. The owner thinks its a 318i, but i thought there was only a 318is made in 1994? Am i wrong?
Not sure what my plans are for it yet, either strip it and make a starter track toy for myself, or put an engine in and sell it on.
Will a 318is engine fit straight in if its a 318i?
What is the power output of the "is" engine compared to the "i"? I know the "is" engine is a twin cam 16v compared to a single cam 8v but thats where my knowledge ends!
Thanks in advance!

318is engine was an M42 upto about 96 - 1.8L DOHC. 96 onwards was the M44 engine - 1.9L. Both approx 140bhp
The M42 went through a couple of revisions and has a known history with the timing chain - basically if it's noisy, then overhaul it, the chain guides, tensioner, etc.
The M44 is generally more reliable.
The 1994 318i will be the M43 chain driven engine, and approx 110 or 115bhp.
If you change the type of engine, you'll need to take into account the electronics too. And if you put an M44 engine in, the ECU will very likely have EWS, so you'll need to get the EWS module matched up and the ignition keys too.
The M42 is generally regarded as more tunable.

I think the chain/tensioner is generally more reliable in the e36 M42s.

Either way, the M42 and M44 are the most reliable engines in the e36 range.
