This question at hand may be one of the most hotly contested for all rotarians. Not being shy at Rotary Performance to give an opinion, we’ll answer an unequivocal yes. Depending on the circumstances, both are absolutely right. Let’s explore…   WHY PREMIX First, why is premixing, or for that matter oil injection required on a rotary engine? Ever since the earliest days of rotary engines, controlling wear of the apex seals has been a challenge. Apex seals have a unique place in the world of internal combustion engines. Rotaries operate like a two stroke engine. Every time a face approaches...

We love the Apexi PowerFC. No other engine management solution combines its features. With all this appreciation, nothing breaks your heart like when things go wrong. When they do, we can help. Most common mishaps can be repaired in house at Rotary Performance.   Injector driver failure (commonly secondary) Radiator fan driver failure Air pump driver failure AC compressor signal driver failure 2-speed fuel pump driver failure Oil metering pump servo control failure   There are other possibilities, but these are the most common.

Not every bad part is noticeably broken under normal circumstances. Today's post focuses on a performance complaint which the customer described as a fuel injection problem. Everything was fine at idle, but there was a distinct miss under load. Proper diagnoses is critical to fixing cars quickly and economically.

It's certain to raise eyebrows when tragedy is combined with restoration. Unfortunately, that is commonly the case when projects begin with a rope, a tow chain or  a buddy's truck and trailer. Let us begin with the "Greekly Tragic" proper prologue. Enter one 1986 RX-7 Sport model. A worthy candidate stored lovingly in a garage for 15+ years. Being a Sport model, this steed possesses the simplicity and lightness of a base model combined with the brakes and wheel diameter of a GXL. Having an undented aluminum hood and straight body without corrosion, worthiness of resurrection is obvious. May we introduce the catalyst of the tragic, the innocent...
