first off, you should be in the EG forum. Neways, You can put the H22A in your car or the B18C1 or 5. I recommend the C1 for price and ease of installation. If you have a few more bucks to kill go with the C5. The H22 makes awesome torque but that is very deceiving, making the car seem faster than it is. Bone for bone the C5 will outperform. It has the best gear ratio's for an allmotor car, LSD, and plenty of power.
