Starting some of the documentation for the planned swap and rebuild ahead. S52 will be gone through and dropped in with OBD-II in tact.
I am not 100% clear on all bits required to keep it OBD-II but I'm sure some
veterans around here can help me out. Only thing I am sure of right now
will be a TRM tune with EWS,secondary O2,and secondary air pump written
out of the DME.
A little background on the current status.
1991 318is acquired May 2011
completed the NV M50 swap in September. Drove it, love it, just want moar power to play with.
So I came across this unit on CL. From a 98 with about 190K.
As much as I would love to just swap the bad boy in for the flogging
this summer I am refraining from such until I can take it down and have
a machine shop go through the head and inspect the cylinder bores
for wear.
So as progress starts and tear down begins I will try to update with as many pics and questions as possible.
