325i or 320i?

[hellrotcompact]

Hey guys,

Just wondering if anyone knows JUST by looking at the engine in an E30 how to tell the difference between a 320i and a 325i as I believe they both have the same engine block but just one is bored out and the other isn't.

Are there any tell tale signs?

cheers

should have 2.5 stamped on the head near the exhaust manifold and the 325 normaly has an oil cooler.
The inlet manifolds are diffrent shape/size but someone could of put a 2.5 inlet on the 2.0

[Cloggy Saint]

The intake manifold on a 2.5 is more rounded than on the 2.0

oh ok cheers mate, would the 320 have a stamp saying 320 then for this matter?

what is the difference in the look of the manifolds?

[ed325i]

The 320 or 323 will have 731 on the head and the 325 will have 885.

[hellrotcompact]

basically.....is this a 325i engine?

[ed325i]

yes it is.

[hellrotcompact]

cheers mate....its the manifold that gives it away eh?

[dazleeds]

but that car sure aint an original 325

[ed325i]

Whats it in a touring ?

[hellrotcompact]

why is it not a original 325 engine?

[dazleeds]

oh ok cool thanks for telling me would this matter? And does it really make a difference?
Why would they put it in the boot? I know 5 series have it under the rear seats lol

[dazleeds]

wont make any difference

it was in the boot to aid weight distribution on the car as far as i know

[hellrotcompact]

Thats what i thought but BM's are RWD lol so where is the sense in that

[Rosc0PColtrane]

BM are anal about 50-50 weight distribution
