#337824 Hi guys, my ride is a 93 eg running on a B20v engine. This may sound stupid but my question is what compression ratio I'm having since it's a so called Frankenstein engine? Block is a B20b (CR-8.8:1) whereas the head is a B16a (CR-10.4:1). Pardon me if I got the CR wrong. It's basically bone stock without any kind of up-grade of any performance internal organs except whatever parts that's necessary to make it runs. It's utilizes a p30 ecu, accompanied by the usual IMH. So my question are (1) what should my CR be now? And (2) what kind of HP range I'm roughly in now? Anyone pls???
