Im considering turbocharging my b16a. I want to, if possible, use stock internals and injectors. I realise this severely limits my boost so I'm looking to run at 5psi. This should yield about 30% more power (I hope!). Can I use a rising rate fuel pressure riser to increase the fuel pressure on the back of the stock injectors in accordance to boost level to supply enough fuel for 5 psi of boost without running lean or detting (im going to run 98 Ron fuel, and an air-air intercooler to help.) I shall also retard static ignition if detting occurs. What are the problems with the ecu/sensors etc when turbocharging this engine, will the engine check light come on or will the motor cut out without electrical modification when boost is sensed?? thanks for help
