If that's a month's worth of carbon, your engine is sick, big-time. Rings worn plus valve stem seals plus it looks like it's running WAY too rich.

You replaced those only a month ago?!? If that's the case, your engine is running terribly.

ok, so you on the right track, but. the 413 Red label is an OBD1 ecu. your M52 engine is OBDII. so unless your going to convert to obd1 which is easily done, your going to have to use your original ecu

would you recommend going obd 1 and what are the downfalls in your opinion will i lose the benefits of an obd 2 system

It depends what you want. I'm going obd1 because at the current time I don't have the skill or time to learn how to tune a obd2 system. But from what I've read the obd2 system is a much better at almost everything.

To do the obd1 swap you need a m50b25tu obd1 engine wiring harness and that red label413 ecu you have. As well as all the obd1 sensors. You also get to use the m50 intake manifold which will give you better airflow and thus more power. You need the obd1 fuel rail and m50 valve cover, or you can modify you m52 vc. Bimmer forums has a few different resource forums on odb1 conversions. I would look there if you were going to do it.

As far as expected power gains you might see 10-20 horse power gain with the right tune

ok so i got all the parts for the conversion but will retain my m52 manifold as i did not find an m50 manifold. is it possible to keep my manifold and do the conversion to obd 1 now and later change the mani when i have one?

Oh man, if you do that, you will be lacking top end quite a bit and the speed will flatten out quickly. You will be torquey still.

As my good Canadian friend jkmeisl said, OBD II is so much better in many ways. The wiring is cleaner. Everything underneath the intake manifold is cleaner. But the problem you will run into is tuning. It is more expensive to tune an OBD II car versus an OBD I car. However, with an OBD I car, you will have much more tuning potential (just pop out the chip and get a tuned chip from Turner Motorsports).

Concerning your plugs, you can also put in a small amount of autotragic transmission fluid in the engine, and a very small amount in your gas tank. Then run the car VERY hard. That will clean out the internals crazily well. You can also get BG Products internationally, as well as Seafoam. If you are near downtown Beirut, there should be plenty of shops there that sell products like BG and Seafoam and Marvel's Mystery (it's ATF) oil.

If you go with a different manifold, you will need to re-tune. You'll might as well put the intake manifold on now and get it all done in one fell swoop.

I would look high and low for an m50 intake mani if you and even thinking of the obd1 swap. The intake manifold is were 80% of your power from the swap will come from

ok so its gonna happen obd 1 swap will comence today.

The tune i have is pretty good but i learned today it is for an engine with an m50 mani but i still havent found one, im planning to turn the car over tomorrow will i be doing harm by driving it with my m52 mani. im also going to delete the vanos, unless you guys can convince me not to as the car will be drifted(high rpm the tune gets the car to 7200rpm) and i do want to have the ability to tune for agressive cams (i did drive an e30 with an m50 stroker and to be honest it had more low end torque then i did).

also i know this is going to make me look stupid but when i have the funds i will be going turbo but that is going to take time and will be on a perfect block, head, and will be built before i take this engine out of my car(i might even buy another e36 for that engine but that project is too far in the future to talk about now.), also everyone keeps telling me that obd2 is better for turbo why is that.

more pic later today.

OBD 2, from what I saw on the Bimmerforums posts, is much easier and more stable to tune for a turbo modification. But no real solid reason why, aside from getting the proper tune.

As far as driving your car with the M52 mani, not really. Just might be running a little rich. Just make sure to unplug the battery for 10 seconds, then plug it back in. Then run the car hard to train the ECU.
