Do you mean an E36 Daz? I only know of one E30 M50 B20 and that was an accident!

Guess you could fit the M50 B25 mainfold, they are different part no's but not sure how much bigger the ports are. A good Remap maybe?

Think the kindest thing you can do to an E36 is to find a stone wall..... winkeye

There is absolutley nothing you can do with an M50 2 litre. The 325i manifold will fit but the ports are so much bigger that the incoming charge will hit the step down top the smaller ports and lose power. The manifolds are O ringed and plastic so fitting a 325i TB isn't an option.
The only thing that can be done is to get it remapped. The £250 that costs will buy a 2.5..........
