Inexpensive power upgrades for the 325i/iS/iX motor

[civic_eater]

what is involved in changing it to a 302 ford injector. do i need the ford injector plugs to splice them in or do the m20 plugs fit?

[everlast]

They fit right in, but you'll need some serious supporting mods to make them work. With the standard chip in the bmw ecu, they'll just flood the engine.

what kind of chip do u recommend?where can i find it and price range?thanks.

[everlast]

depends entirely on your goals, $ willing to invest, etc. Mark D (here on the board) has great chips available for 17/19# injectors.

Unless I'm wrong, 302 Ford injectors are either 36# or 42#. You don't need anything over 21# unless you're have forced induction (turbo / super charger).

If you're keeping the motor stock, just get 17# injectors from an M50 and a chip from Mark D. You'll see the most gain for the dollar that way.

When I picked up my car, it came with a M30 AFM. I need to get a new cone air filter but w/e. What is the price range for Mark D chip? I've been reading the forum a lot and his name is posted on pretty much everything =\. I might stop by within a couple weeks after I get my brake and fuel lines changed and some other things done. Might look into the m50 injectors and get the chip from Mark if the price is reasonable.

You can see prices on my website. www.dsylva-tech.ca

Did you see the banner here? Just click on it. The banner says "Enhanced Automotive Technology"

There is also a group buy happening here, it was really for OBD-2 files but you can get in on that if you like.

The price is more than reasonable for what you get.

Sorry I didn't track you down MarkD. I'll just pop by one day in the future and get it done at your shop so that way it can be fine tuned if need be. I wouldn't want to mess things up since I'm a newbie with BMW's let alone any GM product car. Thanks for the website link I'll be sure to keep 250$ on the side so when the car is ready (I'm doing the floors right now and then the brakes).

Does anyone know or have a 86-88 3 series (325i) convertible engine for sale or perhaps a car they are parting out. Need trunk lid and some interior components also. Lemme know.

Any suggestions for making a heat shield around my cone filter?also what are your thoughts on a velocity stack?
