hi

can anyone point me in the right direction to getting a exhaust manifold for the M50 conversion, or suggestions on which manifold i can get modified.

many thanks

"Dan The" does a manifold alteration for the oem manifold. Best value and tried and tested solution.

Have a look in the wiki at 'engine swap M5x'

or

if you have the money, fritz' bits manifold for £xxxx

That's the M52 tubular manifold, rather than the M50 cast one, but my first M50 conversion was done with a cast manifold.
IIRC, all that was required was to move one of the flanges upwards.
Conveniently, at the time, a professional welder asked me to sort out the RCD tripping in his workshop*, so we came to an arrangement.

*Took all of 15 minutes!

2.8 manifold fits the M50 fine. It's just that when I did my first M50, second hand M52 bits weren't that plentiful.
Looking for info. on some detail of that conversion was how I originally found and joined the 'zone'.
