1. CX Racing FMIC 2. Water/Methanol Injection - the delivery is never consistent and I don't trust these systems worth a damn unless it's properly engineered with proper safeties and a multi parameter map to control delivery. The problem with most of these systems is they duty cycle the pump to control delivery which is a poor way to do it. The pump should be run continuously and they should have a solenoid / injector to control delivery. 3. Jecs 555 injectors... The only injectors for side feed I would get would be Nismos. Too many other injectors are redrilled and don't flow consistently. This leads to all kinds of damage down the road.
