Gen1 4g92 4g93 intake manifold compare

Got chance to compare Gen1 4G92P SOHC 16 Valve intake manifold with 4G93 DOHC 16 Valve MPI intake manifold

have 4G92-MIVEC DOHC 16 Valve also to add to compare

And on OEM intake of 93 has few millimeter bigger TB hole that 92 sohc engine. And TB compared is also have few millimeters bigger TB hole from IN side.

What is visually seen that 93 has way bigger runners then 92

Back side of DOHC and SOHC intake manifolds 4g93 and 4g92 intakes manifold from back, and visually seen that GTI(4G93 DOHC) intake has bigger runners.	TB side of DOHC and SOHC intake manifolds As seen on right SOHC manifold has TB hole bored for EVO1-3,Galant,Eclipse,Mivec etc. TB	MIVEC Gen1 intake manifold As seen this manifold has bigger runners looks same size as GTI one, and has extra 2 sensor holes, one to injectors side other in back.	MIVEC Gen1 intake manifold with partly assembly From top seen mentioned sensors, this picture shows intake just without full rail and injectors, but all in place, TB, engine hanger bracket, ignition module, ignition coil etc.
