I didn't pass the sniff test. It might be the O2 sensor.It passed! Man am I stoked.
It was a painless process.
I showed up for my appointment time, told them that I did an engine change with a 95 3.0 M3 motor. They looked at the car for about 20 minutes and then ran it on the dyno. It didn't pass the tailpipe test the first time, so they let it idle a while and then re-ran it after the cat got hot and it passed.
Basically, here is what I have
s52 with s50 valve cover. I did this for visual reasons and so i could run the proper cranckase vent with the 2 hoses off of it.
e30 charcoal cannister with the e36 evap purge valve mounted on the side with all lines in place
s52 exhaust manifolds with the o2 ports and air injection ports welded shut
k&n cone air filter
magnaflow cat with 1 o2 sensor
my swap looks pretty clean, which i think helped a lot. they said they get all sorts of junk in there, and when your work is clean, it shows that you haven't cut corners and probably makes their job easier.
i've got the bar label on the shock tower now so i can smog it as a 95.
if anyone else has questions, pm me or post here.
Which O2 sensor are you running the M20 one or the S50 one? Does that make a difference?Comment
