m20b28 turbo

[abit]

Hey, could someone can help, planning to turboing my NA m20b28, now setup is m52b28 single vanos crank, 130mm rods and late model m20b25 short skirt pistons, no material removed from head or block.
planning on low boost ~0.5bar, I want to build it with stock parts from other bmw engines, so what pistons/rods should I use to get proper compression rate for turbo, or maybe the current setup is ok for that boost?
planning to o-ring block, stock headgasket + arp or so headstuds.
and if m50b25 green top inectors could be enough for low boost engine, or better to get ''bigger'' ones, maybe can reccomend something from oem injectors? running on 3.5 bar fpr.

Why only .5 bar? A stock engine with head studs can handle more than that and remain relatively reliable.

yeah I heard about that.

I just want to stay on m50 management, but I heard that going over 0.5bar it starts to go lean, even with remaping. Or I'm wrong? If I'm wrong, ~1bar would be fine :D

I'm not sure what your budget is but if you're spending the money to build a stroker I would recommend spending the extra bit of money on a good management system (megasquirt, miller, etc) and fuel system to get the whole potential of the m20 (~1bar+). Good luck with your build, sir!
