    BMW 3 Series Forum - Technical Talk on the BMW E21
    After "modding" my airbox, AKA cutting a hole in the side of it, I can now notice a VERY distinctive change in induction note at 4500RPM. It's really noticeable, it's like VTEC crossover nearly. I'm not sure if theres a power gain when it happens, maybe slightly, but I was just wondering what it...

    BMW 3 Series Forum - Technical Talk on the BMW E21
    I have the same engine "M43 1.8l " putted in a E36 replacing the M40 '1.6' on the first time. I noticed the idle isn't stable, so I started by cleaning the MAF, it's gets better and I still have the prob though until I realized that some bolt linked to the injection system is a bit loosen, I...

However i wish to start with the manifold, but nowhere (even ebay) seems to be showing me much luck. Im not looking for...
