On a 3.2 OBD II to OBD I conversion...does that swap include swaping to a M50 manifold? If not, were does this supposed extra power come from. If the added power is from the different electronics couldn't that power be gained through a programer (ie shark injector)?

yes, the OBDI swap includes the m50 manifold. The power is in the manifold conversion, nothing more.

If its just the manifold then why do people do a whole OBD 1 conversion? Couldn't they jus switch the manifold for a lot cheaper? Just curious

There is no power to be gained from doing an OBD1 conversion that can't be gained with OBD2.

So why do people do it then?

I don't know. My only guess is because upgrading the software used to be difficult on OBD2 and some people think that's still true.

It was only till about 2-3 years ago people learned how to swap the m50 manifold on to an OBDII car.

OBDII tuning has also advanced to where you don't need OBDI anymore to custom tune.

What he said, it used to be hard to tune obdII it is now easier for the tuners although I have no idea how/why since I don't tune :)

That's what I thought...the manifold is where the power was gained. Everybody was saying the whole conversion is where the power is at.

If you have an OBD-1 car will it be helpful in making everything work correctly as far as computers hooking up and what not. SO would it make evrything more seemless and easier if i for instance bought a 3.2 for my 325is, to turn it to OBD-1?

You do things by th chassis not the motor, your car is OBDI so you would convert the motor to OBDI. Which is really easy, you already have all the parts.

Just saw your a euro, which means you don't have OBD anything.
