Ah I see, if you look up m50 manifold conversion you will find lots of information. With remap it can give 229hp, with your exhaust work maybe more. You seem to like performance mod so maybe you will be interested in this. Car looks great though.Intake manifold from m54b30
I did not notice any effect )
After installing Remus headers ans SS catback bacame much more responsive
I do not have remap, did not find info about it;(
