BMW M51 Questions
BMW M51 Questions
Are these a straight swap with a M51 electronic inline pump? Obviously when converting I'd need a 3 series accelerator pedal and cable, is anything else required?

Next, I want to try run this pump (which will have a 12mm head) with my 12cm HX35. Is this just being over ambitious or is it likely to spool it?

Other plans are 3" exhaust, boost controller, large aftermarket FMIC, boost gauge, EGT gauge, external wastegate possibly, maybe water meth.
Lastly, I assume that for over 250 bhp I will need ARP head studs, does anyone know if any other BMW engines have the same size/thread/length head studs? ARP don't stock any directly for the M51.
Hi all, I have recently acquired a M21 mechanical inline pump.
