The guy said, hook everything up, make it look clean, new catalytic converters and you will pass.

Why don't you do the swap and report back with results and refs commentsOriginally posted by wworm View Post2man tried to BAR his m52 swap as an m50 and it was apparently a huge pain in the ass, more of a pain in the ass than swapping back to an m52 manifold for BAROriginally posted by 36brua View PostBut wasn't he using used cats....

Let me clear this up...
I had a M52 with M50 manifold, S52 cams, 21.5# Injectors, OBD1 TRM Tune.
I started with a stock M50 downpipe with ~150k, then to a slightly modified (just to work on OBD1) S52 downpipe then finally brand new Magnaflow CA legal cats. The tune also changed a few times....
I blame 2 things for my car not passing:
#1 I shouldve listened to my mechanic and bought a WAR chip so he couldve created 2 tunes for me, a SMOG tune and a performance tune. I didnt listen and bought off the shelf chips for my modified car.
#2 The ref would let the car sit for 20-30 minutes when I would arrive, so the cats were never really warm enough, and combined with #1 this resulted in it not passing the tailpipe emissions test and No BAR sticker.
To answer your questions, he never checked the engine. I showed him the VIN sticker on the ECU and we went based off that, but your results may vary. The closer to stock the car and motor are, the easier it should be. Mine was quite a big off of what a stock M50 was so it made my life harder.
It all depends on what you are starting with and what resources you have to accomplish the swap. Parts car on hand is the most ideal start. I had none of that.Simon

Just as an "am I going in the right direction?" question; I am looking at a 97 M3 and can potentially make a deal for the entire car. Would this be a good candidate for a swap over to my 88 convertible? Would the extra smog shit (air pump, etc) make it more difficult than another model year of donor car?
Thanks,
Sean
