What is B16a2?
1.
The stock DOHC VTEC 1.6 liter engine in a 99-2000 Honda Civic Si. This beast produces 160hp and 111 lb-ft of torque (thats 100hp per liter!). At 5500RPM VTEC kicks in and you can really hear and feel it.
"Yeah man, I put the B16A2 motor in my hatch, it's hella tight now!"
2.
The Honda motor which came stock on all 92-95 EG6's in Japan. Often a J-spec/JDM motor, this engine is largely affiliated with American Honda Civic swaps. The SiR II B16A differs in the extreme from the B16A SiR which came on all 88-91 EF8, EF9 CR-X SiR. The B16A2 came stock in JDM SiR II EG9 Del Sols, EG2 and EG6 CR-X's or 3 and 4 Door Civics. The B16A SiR II is also a direct swap into USDM 92-95 EJ1 (EX Coupes), EH6 (Del Sol Si), EH3 (Hatchback Civic Si), and EH9 (EX 4 Door) Civics, it can be swapped into a DX, LX coupe and DX, VX, and CX Hatchback as well, yet requires a VTEC switch. The reason why most Honda enthusiasts are after this engine is because of it's universal characteristics as well as it's practicality. Increase your performance with minor weight gain (The B16A Sir II is only 10lbs heavier than a stock USDM SOHC VTEC D series or D16Z6) and still be able to rely on getting excellent gas mileage and Honda dependability. The A1 and A2 mean: A1 - First Generation (88-91)....A2 or SiR II - Second Generation (92-95 and 96-00). The B16A1 is a weaker version of the B16A2, 10hp less and less ft lbs of torque.
B16A2 and SiR II are two different engines, yet they have the same characteristics. From two different times in two different vehicles. B16A2 is a USDM version of the B16 SiR II which is primarily a JDM engine.
