Summary of change:
'''Big Six Turbo''' BMW called M30 engines as "Big Six" (M20, just like mine is "Little Six"). This page is about an M30B34 turbo engine, originally in a 745i from 1985. http://www.bmwpower.hu/gallery/albums/userpics/10152/normal_45i%20017.jpg It's not a weak car even it's stock form (3.5 Turbo, automatic), but this engine will go into a light chassis (e30), with manual gearbox and possibly motor tuning, more efficient turbo design, etc. Here I try to put together what's needed to GenBoard it :) '''Original setup''' Car outlines originally: * Engine: M30B34 turbo, 3400cc, '''6 cyl inline''', 12 Valves, SOHC * Fuel injection: Bosch injectors (part no. 0 280 150 200?) maybe 270 cc/min@3bars. R=? Ohms. Needs to be verified * Fuel pump: Stock * Stock pressure regulator * '''Turbo''': stock KKK K27 * Idle control : stock. (What kind? need to be verified) * Intake: stock AFM, Small stock air-to-air intercooler * Factory throttle pos switch (3 state; idle, between and WOT?) * '''stock 60 teeth VR crank-trigger''' no missing tooth AFAIK! This will need to be replaced by the late model M30B35 with 60-2. ** Now it's equipped with the 60-2. Do someone know the missing tooth position relative to cyl#1 TDC, or any other parameters? *** Maybe the M20 baby series engine uses similar crank triggering, see http://www.vems.hu/wiki/index.php?page=MembersPage%2FGergelyLezsak%2FTrigger * Cam position sensor? * Coolant sensors? * '''Knock'''. Two factory installed knock sensors. * More sensors: O2 sensor? , IAT? * orig '''ECU''': Bosch Motronic 0 046 430 136 0 ---- * Here is a similar car: MembersPage/MattiasSandgren/BmwSevenTwentyEight - Unfortunately the owner had to sell it for 1300 euro.. * Another similar car: MembersPage/MattiasSandgren/BmwFiveTwentyEight (Will be my daily driver //Mattias) and a [http://media.savarturbo.se/~mattias/vems/bmw_e23_728_turbo/pimpride_2005.avi movie clip] for motivation //Emil Larsson ----
