Hello group ,
Im new here in r3vlimited, i dont know if i should post directly here or make presentation, if im in the wrong section please admin feel free to redirect me.
Im Harry, driving a 1973 bmw 2002, m20b25 eurospecs (late model with lambda sensor ) my engine really need a rebuilt (smoking and ticketing) as my gearbox (getrag 250 , too fragile ).
instead of just rebuilding it in stock form , i was thinking to stroke it using m51d25 , as s52 is not aivalable in this small island, i know a guy in Sweden did it using 130mm rods , stock piston (machine it 14mm ) and m51d25 crank from e36 325turbo diesel, i plan to do the same. my questions are :
1/ In some website , they said i should deck the block down to 1.1mm , if my calculation is right that will give me 11:1 , perfect but does the decking affect the timing ?
2/ Which piggyback should i use ?
3/ Should i use 280degree cam ?
4/ how much bhp i can expect ?
5/ I can found a e36 m42 engine for cheap, should i swap , its week end car , but also want to run 13sec quarter miles for next year season.
thank you
