Nothing. That's the code for the engine from an Integra GSR. The GSR is a pain in the ass, IMO. It is in my car and I'm replacing the GSR head with a Type R head, and all toda internals. I'm running a B18c5 USDM ITR block now @ 10.5:1.

You can do an h22a swap, but the motor is really heavy. You will need to beef up your suspension quite a bit. If you want a 1.8 liter, get the Type R. There have also been numerious threads about this subject in this forum. I suggest you utilize the search feature.
