Time and Time again in this forum I have read comments that it best to convert your OBDII bimmer to OBDI if you are interested in making performance modifications to your Bimmer.
Im curious as to where all the benefits lie with this conversion.... are the increases in performance amplified with the OBDI conversion with other addon's?
Im debating making some performance upgrades to my OBDII bimmer and with my budget Im not sure if the investment in the conversion to OBDI is worth it?
~$2200 (that leaves $300 to buy a girlfriend a nice gift so I won't 'hear it' for spending all this money on my other baby :cheers
If I go with the OBDI conversion then basically I will need to chuck Intake Manifold, & Pulley Kit just to make the budget........
Is this conversion still worth it for those of us that a modding on a budget?
I've looked at the M50 intake on m3motorworks website. I didn't think you could just swap intakes. I thought you had to change the ECU and wiring harness also.
I wanted to go back to OBD1 too, but then you can't sell your car =/
Not to mention if your car gets a police check they're going to impound it, oh, and you'll have to pay a couple hundered bucks to pass smog depending on where you live.
Well my car is registered in the NYC metro, so emissions is an issue.
I know my mechanic will hook me up, he has before..... but I don't want to make modifications that would adversely effect the resale value of the car like that
Im aware the fact that making modifications to a car CAN have an adverse effect to the resale value of a car.
Since, I live in Manhattan, and this car basically sits in a garage 26 of 30 days in the month I expect the car will be around for awhile.... hell thats why I bought a 96 that I could pay cash for instead of a 2003 on loan. But, its one thing to add mods (CAI, underdrive pulley, intake, exhaust, shark) that may hinder its resale then make a total conversion (OBDII to OBDI) that makes the vechile impossible to sell because it won't pass NY emissions.
so why would people do an obd1 to obd2 conversion, would you do it just to be able to chip your car, obd2 was made because of new emmissions laws, everything dealing with emissions had to be controlled by the computer, i still don't see why someone would do this to their car, can someone post a reason for it not more reasons against it, which is what the original question was
Sorry I didnt' see this thread earlier, maybe I can help clarify a bit....
Yes doing this conversion is illegal. So is adding a free flow stainless steel exhaust. Or going with aftermarket software (a chip). But there is no way anyone who could do anything about this would ever know. I have a very strict emissions testing process residents of middle TN must go through, and I have had no problems at all.
Secondly, it's very well worth the money, because in addtion to a 30 hp gain (yes, a true 30hp gain on the M52 2.8L), it gives you a much improved throtle body, airbox, and the ability to gain even more power by giving one the ability to add custom software.
And for those who don't know, the conversion consists of the following...
The OBDII-OBDI conversion is a complete intake/engine management change. The air flow meter, throtle body, air box, intake, wiring harness, dme, etc. are all taken from the '92-95 cars and replace the more restrictive OBDII components.

I'll work on that, been real busy lately. Here's the link.....{HERE}
Their good people. They certainly understand BMW owners and carry a variety of cool mods. I would love to pick up one of their 6speed conversion kits, but just can't justify the cost.
