  8. Help! My car is driving me crazy

    E30 (1982 - 1993)
    I've been having a seriously annoying problem with my car the past 8 months. It's been having some trouble idling. It idles very roughly and then stalls. I've had two instances where it seems to be misfiring as a result of this, and I can smell fuel in the exhaust, so I assume it's running rich...
  9. M20 Oil Pressure Source

    E34 (1989 - 1995)
    Quick stupid thread... Still more dreaming and planning.. :rolleyes: So, I want to run an oil cooler, which with the turbo, would make things all messy with oil hoses everywhere. I could do things traditionally and run the turbo out of the oil pressure sensor (t fitting) ending up in the oil pan...
  10. Drivetrain Weak Links

    E34 (1989 - 1995)
    Hey, I'm wondering if you guys know if I actually have different drive-train parts other than diff and tranny? Like if I will need 540i axles for a large power increase, etc? Also, I did an M20 turbo build parts list on FI forum. If I wanted to make a molehill a mountain, I could call it my...
  11. M20 Turbo Parts List

    Forced Induction
    Hey guys, the FI forums are always quiet, so I figured I'd post the parts needed to build a 330ish WHP M20B25. This is less of a build thread and more of a BMW cooking show. Anyway, the total should range from about $3300 to $5000 with optional parts listed. I've done every calculation in the...
  12. 1986 BMW E28 520i low compression on all cylinders after head gasket change? HELP!

    E28 (1982 - 1988)
    Hello, After recently servicing my 1986 BMW E28 520i Lux I now have low compression on all cylinders. All around 4.5bar/65psi :cry: This was tested hot and only a minor increase when doing a wet test (small amount of oil on the top of each piston) During the service I have done the...
  13. M20 Low Vacuum

    E30 (1982 - 1993)
    I attached a vacuum gauge to my m20 with 133,000 miles and it has a steady vacuum at about 15inHg when it should be at 20inHg . The engine idles rough, but runs perfect when not idling, and gets about 17mpg which I believe is low. I have checked the valve clearances and some vacuum lines but...
  14. Compression Test

    E30 (1982 - 1993)
    I have 213k miles on my 90' 325I and my compression is very low in cylinders 6 and 5 it's 120psi. And it increases as I go to the front of the engine. What is the reasoning to this? About 140 or more psi in cylinders 3 2 and 1. I also have a lot of carbon build up on the spark plugs in cylinder...

    E34 (1989 - 1995)
    Hey guys I've been having a problem with my '90 525i for about two weeks now. When I'm in low rpm (under 3500) my car has hardly any acceleration, if I'm cruising at 50 in 4th and mash the gas it very slowly picks up. The other (worse) problem I have is jerking/stuttering around 1800-2200 rpm at...
