Basically First Letter is the Engine Series

Then the two numbers are the engines displacement.

Then the revision of that motor.

For Example. B18A1

B (series)

18 (1.8 liter)

A1 (a1 referring to a 90-93 Integra LS/RS, if it just had a letter no number following, then its a JDM motor which was intended for use in Japan)

Your Basically Asking the difference between, B16/B18/B20 and H22.

Well all of those are DOHC (what is that, you might say, Dual OverHead Cam)

as shown below:

All B16s are DOHC VTEC in stock form.

B18's depending on the exact engine, it can be just DOHC (no vtec) or DOHC VTEC, for quick info, its basically B18A1 (older LS) B18B1 (newer LS) B18A (japanese accord engine) and B18B4 those engines were NOT VTEC in stock form, they can be converted to VTEC aka LS-VTEC conversions but none of the previous were VTEC, Now for the Rest of the B18s like the B18C, B18C1-7 those engines were DOHC VTEC.

B20 NEVER CAME STOCK VTEC, its a Honda Cr-v Motor, which people use the same concept of LS-VTEC (for the B20's called B20VTEC or CR-VTEC) and convert it, basically poor mans way of having a DOHC VTEC B-series.

H22 is DOHC and VTEC, the B-series rev harder because there smaller engines, yet this engine has more torque than the B-series (stock).

Which is the Best engine for YOU? It depends on your preference, and whether you are going to go naturally aspired (non-turbo) or forced induction (turbo).

If it was me i'd go H22 engine, B-series transmission, and possibly turbo.

Edit for ae: Yes look up H2B its a adapter plate to mate a H22 to a B-series transmission (best of both worlds).

Hey what's up, I got a question about the h2b kit and mounting a h22 to a 91 Hatchback.
Is it possible to do that?
With my hatch
