The lengthened manifold will lower power
The cam
must be reprofiled due to the roller rockers
Roller rockers will add a smidgeon to hp
The lighter crankshaft will add to hp
Piston rings won't make an hp difference
Swirl control valve - not totally certain what this is
Double tipped plats? The SR20 has
always come with them
Variacle muffler might help some
