Will a b16 fit both crx and 1988 integra?

Yes, a B16 engine can fit both the Honda CRX and the 1988 Acura Integra, as they share similar engine bay dimensions and mounting points. However, some modifications may be necessary for proper fitment, such as motor mounts, wiring harnesses, and possibly changes to the exhaust system. It's advisable to check compatibility with specific models and configurations, as variations in trim and drivetrain can affect the swap process.
