What motor is in a 1998 Acura Integra?
The 1998 Acura Integra in the United States primarily used two engines, depending on trim: RS/LS with a 1.8-liter non-VTEC B18B1, and GS-R with a 1.8-liter DOHC VTEC B18C1. A U.S. Integra Type R was not offered in 1998.
Engine options by trim in North America
The following list outlines the two most common engine configurations you’d find on a 1998 Integra sold in North America, along with approximate outputs and distinguishing features.
- RS and LS trims: 1.8 L inline-4, B18B1, non-VTEC, about 142 horsepower (and similar torque).
- GS-R trim: 1.8 L inline-4, B18C1, DOHC VTEC, about 170 horsepower (factory rating varies by market).
Note: Power ratings can vary slightly by country due to different emissions specifications and testing standards.
How to identify the engine in your car
To confirm which motor your specific Integra has, locate the engine code on the engine block. Common codes are B18B1 for the non-VTEC 1.8L and B18C1 for the VTEC 1.8L. The B in the code stands for the 1.8-liter displacement, while the C indicates VTEC.
Where to look for the engine code
Engine codes are typically stamped on the engine block near the transmission bellhousing or on the valve cover. If you’re unsure, you can also check the Vehicle Identification Number (VIN) and cross-reference the build sheet or owner's manual to confirm the engine family.
Market variations beyond the U.S.
In Canada and other markets, the Integra 1.8L lineup generally mirrored the U.S. options: B18B1 for the base/LS variants and B18C1 for higher-performance variants like GS-R. Some markets offered different emissions-tuning, but the basic engine architecture remained the same.
Always verify with the vehicle’s documentation and the engine stamping to be certain of the exact motor in your specific car.
Summary
In brief, the 1998 Acura Integra offered two main engine configurations in North America: the non-VTEC 1.8L B18B1 in RS/LS and the 1.8L DOHC VTEC B18C1 in the GS-R. The U.S. did not officially market an Integra Type R in 1998. To be sure, check the engine code on the block and match it to the codes above.
