I was wondering about the jdm d15b vtec swap. 1. Is it cost effecient for a fourth gen hatch? 2. Is it easy to convert the 91 hatch to obd 1. For instance using a modified harness? 3. Does the same performance parts for a d16z6 fits this motor? Ex pistons, cam, rods and timing belt. 4. Where I can find one of these engines and/or ecus for this engine? 5. Do i have to change axles, hubs, mounts or linkages? I would perfer to use either a 91 si trans or dohc zc trans, if so what do i need to use these transmissions. Any input will be greatly appreciated. Im just trying to get some direction.
