+1 to that statement. My AB Mods JX21 B01A is one of my favorite
engines in my arsenal too. I can't understand why Mugen went along
with the new generic configuration offered to them. They dumped
the long l.s.n. in the carb and settled for the three port sleeve.
I think if I had to replace my JX B01A engine, I would buy the Arrow
Racing GTR.21 and have it modded.
