My 1992 E36 325i Coupe has just ticked over 324k's and is fairly buggered. Shortly it will be getting a new engine and manual conversion.
I'm tempted to wait another 1000km's so my 325i will have done 325k's...
The current engine is M50B25nv with a Jatco trans and everything else pretty stock.
The trans was fully reconditioned under insurance about 11 years ago and has done 210k's and is still going. The local trans-shop did a very good job!! It's near buggered again now though - the jerk is back and it flares a bit from time to time.
What's going in:
M50B25nv stroked to 3L (M54B30 internals)
S50 Schrick Cams + Vanos conversion & oil filter housing from a M52B28 (this is supposed to work)
Update - S50US Schrick Cams...
Getrag 6-speed manual conversion kit
M3 Full Exhaust
Update - Including Headers
New all Ally Radiator
Link G4+ ECU
M50TUB25 Wiring Loom
The engine will be dyno tuned.
Using the Link ECU means I should be able to use the M50 crank and cam sensors but will learn if this works at startup.
I have a M52B28 donor engine to rob all the vanos parts required. Depending on advise the injectors may also be used from the B28.
With the B28 available to rob parts off, if crank sensors, harmonic balancers, cam sensors etc need to be change over to get things working they will be immediately available to install.
Many hours of research has gone into the project to make sure all the interchangable parts will fit but due to the amount of conflicting info on the net I'm not 100% sure all the ducks are lined up. The non-vanos to vanos conversion of the M50 head should be straight forward - the S50 cams will drop straight in and only the front right corner of the casting need to be dremelled a bit to get the vanos clearance. The two heads share the same vanos gasket and same cam trays.
The reason for using the M50B25 as a base is so the car looks stock when the bonnet is opened.
At this stage the car will be going into the workshop in just over a week.
Have I missed anything, that's going to bite me?
