B18C1

A short code for a Honda engine. It's the engine that you'll find in your stock 94-01 Acura Integra GSR. It's mostly known for having the best thing ever made, VTEC, compared to it's counterpart without VTEC, the B18B (94-01 Integra LS). You can find the code printed on the front of the motor, near the transmission, along with the engine's serial number.

My GSR has a fully built B18C1.

So what? My integra is stock and still has a B18C1. VTEC FTW!

B18C5 

The B18C5 is one of the most sought after motor swaps to be put in Honda Civics. The motor itself is found in the 1997 - 2001 Integra Type-R (DC2 chassis code). It displaces 1797cc^3, has dual overhead camshafts, has a compression ratio of 10.6:1, and comes equipped with VTEC. The intake and exhaust ports come pre-polished out of the factory for further extraction of power.

Power: 195 hp (145 kw) @ 8000 rpm
130 lb-ft (176 N m) @ 7500 rpm

The transmission that comes coupled with the B18C5 is extremely sought after as well. The transmission comes stock with a close-ratio 5-speed gearset, and LSD (Limited Slip Differential).

"I just scored a B18C5 motor/tranny for my CRX! Damn that things gonna be fast!"

B18a1

Honda engine

Cars: 1990-1993 Acura Integra LS,GS,RS
Power: 130hp 121ft/lb ('90-'91)
140hp 121ft/lb ('92-'93)
Disp: 1834cc
Compression: 9.2:10

If I had an Integra with a B18a1, I would probably just sleeve the block, build the internals, and throw a nice turbo kit on it, due to its larger displacement then the b16 vtecs.
