Hello to all,
Why am I here in the Turbo discussion ? Well because I jumped in to the deep end of the pool and decided to build a turbo project with no experience in fuel injection, turbo chargers or electronic controllers
The basic build will be around a BMW b130 M10 marine engine that is factory new . It was sourced from a boat project that stalled out in the late 1980's and has been sitting ever since
Compression ratio is 8.3 to 1 with flat top pistons so it should be a good candidate for a turbo
The plan is to use L Jetronic fuel injection and a small turbo with 8lbs. of boost all controlled by a Haltech ecu It will have a trigger wheel for ignition and some sort of simple signaling device in place of the distributor to act like a cam sensor so that fuel can be sequential rather that batch
Somewhere I've seen the ignition curve for the turbo and which had a fairly normal advance curve with 10 degrees of retard under boost Does anyone have the curve to share ? It will help tune the Haltech
The other thing I'm looking for is info on the turbo oil return line I know the original was returned to a tap in the front of the oil pan but I think I would prefer a tap in the front timing chair cover
Somewhere in my search I saw a write up of where to place the tap but cant find it now, Anyone have info and or experience with a return to the front cover ?
Thanks in advance for your help
