GEN 4 Caldina ST215 (GT-T) 260PS(256HP) @ 6200rpm 324 N⋅m (239 lb⋅ft) @ 4400rpm Gen 4.5 / 5 Caldina ST246 (GT-Four) 260PS(256HP) @ 6200rpm 324 N⋅m (239 lb⋅ft) @ 4400rpm as i am looking on E-bay at the motors and looking online. someone said that they use the Gen 5 but run the Gen 4 ECU (something about the Key Fob or something) as i have been digging on the forums there is a lot of info and it goes in all directions so hoping to get some clarity on this, any input is welcome.
