is an h22 a direct dropin in a 97 accord with a f22b2

yes & no, u will still need a new ecu, the F22 is r known to be the only motor out there that u can do a SOHC to DOHC head conversion on, no motor swap is a direct swap affair, but u can probably get away with using stock mounts, even though the increase in horsepower, now would be a good time to change out ur mounts anyways, l usually do, its not typically necessary but it will help u in the long run & its only like 300 more to do, l also highly suggest that u do ur clutch & flywheel at this time too since its already exposed

Nope, there is some wiring involved, as well as either modifying a Prelude driver is side mount, or buying an aftermarket one. It also depends on the year of the H22A that you're trying to put in the car (and whether it is USDM or JDM when it comes to the 1996 H22A's). Putting an a '92-'95 H22A (and the '96 JDM H22A) in to ur car will be different from putting a '96-'01 H22A (or '97 is it is JDM) in to ur car. Then it depends on whether it is a regular H22A/H22A1/H22A4 verses a US SH model, or the REAL Japanese Type S ( l say the real one because engine sellers often sell the SiR S-Spec engines as Type S engines). Those 2 engines have a traction control system called ATTS (Active Torque Transfer System). So the transmissions, the physical blocks, & the way the axles work r different from the ''standard'' H22A's.

So basically, u need to be far more specific about what engine you're talking about.
