Just joined. Hoping I might get a bit of information from you folks about my JDM S110. 
To start, can anyone tell me if the HC engines share a bell housing pattern with the EF engine? It would be great if I could “bolt” the larger engine in, and replace the 660-cc EF.
Welcome and no to the HC. Ejde or ejve. Twice the power four times the torque
Welcome to the forums. As Mr G said go for an ejde. they have the same bellhusing as an ef and if like what is in the mira’s and moves should mount to your mounts. Ejde is the largest engine with way more torque you can get that will bolt in with that gearbox pattern in mind.
