Are you referring to the Super Eta? That's not badged any different than the original M20B27 it's based on, it just has B25 valve springs and a few other minor enhancements.
springs, ecu, and pistons and i think camshaft are different in 325

Thats how the "I" engine intakes are. They have larger diamater, short runners for more high end power. There are a lot of differences between an "E" and "I" engine. They look somewhat similar but internal parts are very different.
