Newbie with project

[Super Eta]

I say its a 323i engine. Theres my vote.

BTW looks like a fun project. :up:

i am pretty sure its 2,0 or 2,3 liter m20 engine m20b27 intake runners are thinner and longer, 2,5i runners look like on diegom6 sig. remove one of the plugs, and measure your stroke, that will give you an ansver

O.K guys I will try to get pics of the tac at 6krpm. The redline on my tach is like thin and then it gets thick at 6500 rpm. What does that mean??

if so I bet is a m20b20 or m20b23 (323i)

All E30 m20b25's had Motronic, even in Europe. If you have an L-Jetronic it's propably a m20b23. Also, in a genuine b25 it says 2.5 or 25 on the exhaust side of the block, just above the serial number.

thats correct there should be 2.5 or 25 casted on the exhaust side of the block. right under the head twords the front of the engine can u get us a pic of that side and the stamped number?

[hammoj28]

There is a number on the other side if that's any use. Engine Number???

[hammoj28]

Here is the engine number. 24433502

[YAN-3]

no no dude trust us check the other side or just take a pic and upload it

[hammoj28]

Iv'e looked on the other side and I can't see anything. Is it below the exhaust manifold??

[mikeedler]

that motor is definately not a 2.5. Like said before it is a 2.3 or old 2.0. All 2.5, and 2.7 motors dont have a distributor like that one. (notice no spark plug cables to the front of the motor) As far as the battery goes, all euro models have the battery in the front except for the 2.5 liter models, and all tourings have them in the front. Is that car a right hand drive model? I have a r/hand drive car in my yard and it has that same resivour(spelling) next to the batt. too. anyway it looks like a nice project. good luck.

[hammoj28]

Iv'e seen lots of 325's in the U.K with the battery mounted in the front :?. Yes it is a right hand drive car.

Guys, this is simple , we have manys BMW here, most of them are German specs, came many US specs too(used units from US)....all the M20s that has distributor in the block are or 2.0L , 2.3L or the 2.7L but no way it can be the 2.5L "is" or "i", the b20 , b23 and b27 has the coil and distributor in the pilot side....trust me , I bet it! for me, is a 323i or has the ECu of a 323i with the eta bolck perhaps

[YAN-3]

i agree the casting im talking about is ubove the exhaust manifold ill take some pics toworrow and send em ur way

[hammoj28]

Haven't got pics yet but I thought I would mention this. I heard that the 320 engine didn't have 2 pipes coming from the exhaust manifold!! Well how come mine does?? :?
