What up all. Im thinking about picking up a 90 CRX B18A. Not A1. I understand this is a JDM engine. I drove it and its all good. I would like to know what the red line is on the engine. I think the crx rpm guage only goes up to 5.5 or so. If anyone could shed some light on the subject i would greatly appreciate it. The crx forum has been no help so far. Also I would like to know if there is a good company online i can look up for engine rebuild parts. Thanks so much.
