Any one know where I can get a 13B N/A for a 91 RX-7. I am in So Cal. I was thinking of a rebuild but I cant find anyone who will give me a warm fuzzy that they know what they are doing. I bought the car little over two weeks ago. It was high miles but super clean. There were no problems. Then I coulden't rev past two grand. Replaced fuel filter an o2 sensor Then 10 min later it was running great. 20 min later no oil pressure and smell coolant burning. In two weeks I feel in love with this car and need it running but I only have 2g. I dont like to beg but someone please help me. I can't stand being without my car.
