I might as well post about the builds I´ve been active in for the past many months.
I have two customers buying freshly rebuilt M50B25´s non vanos that I´ll be turbocharging to 500hp. I´m not sure if I´ll torque limit them or what but with electronic boost control I can basically control the torque curve all I want.
M50B25 Non vanos
MLS 0.140 headgasket
6 puck clutch
Sachs 618 pressure plate
Holset HX40 7blade 16cm turbocharger
Split pulse custom manifold
"3 downpipe and exhaust system
24x12x3 intercooler most likely and "3 piping
440cc injectors @ 3.5bar or more fuel pressure
Walbro intank pump
It will be powered by a PnP ecu I´m working on for the M50/S50/M42/M60 families. The base of the ecu is VEMS but I´ll be designing it so that it´s 100% plug n play and no further wiring is needed to get it working (no loose wires outside or inside the ecu).
I´ve been using VEMS on alot of turbo bmw´s and it´s been great and keeps getting better.
I don´t really have any pics at the moment but I do have alot of the parts all ready here just need to buy a E36 for cheap that has or used to have a M50 in it.
If anybody has any questions about the builds then just post them here.
