To begin welcome to HAN.Second only the VX had the Vtec for fuel economy.Third don't go forced induction on any of the motors GSR or Type R. You can get a strong motor just going all motor. Plus if you when races at the track only more respect.The CX is the lightest. Do you have AC, power steering or not. Also look at your vin number. You can always take your car pass any Honda Acura specialist & they'll tell you what model you have.The CX is the easiest to swap engines because of the wire harness & it's the lightest 92-95 hatches.Good luck & post some pictures when complete. One important rule on HAN no street racing allowed only at the track...
