Hi Solh,

I meant the intake. If the 2.1 is a stroker (longer connecting rods),
would the standard manifold on a 1.8 suffice?  I mean, would it mean a
couple pistons shooting through the 1.8 manifold without proper
clearance?  I know the 2.1 is really a drilled 2.0 but I figured that
longer rods were installed to make the compression (???) higher.  Are
the 2.0 intake manifolds identical to the 1.8 or are they slightly
larger?  50mm?  Clue me here!
