  1. My model of MX-5 is: 2.0ND2
  2. I’m based near: South Lakes
  3. I’m looking for technical help or recommendations on: Exhaust manifold compatibility

Hi.
Can anyone confirm whether the exhaust manifold (with Cat) as fitted to the 2.0 litre 184 bhp ND2 engine will fit the 2.0 litre 155bhp ND1 engine? I know it was modified to make it freer flowing but is it a direct swap.

They are the same pattern yes! Do it properly and stick a 4into1 on it like we run on the MK4 race cars, 500 quid job done! :grinning:

Hi MX-5 BRU,

Already done that! :+1: I wish to sell the standard manifold I have taken off and wanted to know if it fits the ND1 as it will increase the sales potential (market size), especially if it improves the breathing on the ND1 as it was one of the improvements from the ND1 to the ND2.
