(posted the same on bfc....)
First, I have searched and am very mechanically-inclined. When i'm ready to go on this, I need to get this swap done & running in 3-4 days and don't want any surpri$es.
Here's the deal, I have an 05/96 E34 520i(M50B20) Touring, i'll be picking up an M52B25 out of an E36 Compact w/ 87k km(55k mi) with everything: Harness, DME, EWS module/keys, Transmission etc. Like I mentioned already, in the interest of keeping the swap easy, tidy, DD'able, and keeping diagnostics somewhat easier, i'm staying OBD2(completely original at this stage, later the M50 mani/fuel rail/tune/cams).
-Both cars are EWS2, so the module & chips will be swapped into the E34.
-Physically, i'm set as the e34 mounting arms/rubbers, E34 pan, oil pickup, dipstick(will be modded for the OBD2) will have the motor sitting in the car. The trans is G250(as is the existing 520i trans)so that will stay bolted on the motor and be dropped in with it.
-I'll be researching the wiring on both of the x20 connectors, adapting it where I must.
So here're my issues(some may become obvious after having both motors in front of me....):
-I'll be using the E34 PS pump, I read somewhere that I have to use the M50 oil filter housing.....is that so?
-Are the obd1 cast manifolds and OBD2 SS mani's interchangeable in that they'll bolt up to the E34 downpipes w/o modification? BTW, in Europe there was no Air Inj, so I have no ports to weld, or air system to deal with). Modding the OBD2's or the DP's are no prob, I have a flex/chop saw/welder.
There are a few other small things that I can't remember atm but i'm sure they'll pop-up later.
