So far we've seen people add extra injectors + standalone fuel controller or else do a returnless-to-returning fuel system conversion.

What if I left the system as returnless but got bigger injectors with a larger pump and used a Haltech E6K standalone ECU to control spark, fuel, and vtec?

Any reason why this wouldn't work, or why I shouldn't do it?

Thnx,

I don't know if you'de need a bigger fuel pump. I'm not sure what psi ours are rated to? Bigger injectors, definately. Maybe upgraded fuel lines as well (bigger diameter). See, the sucky thing is the initial configuration. I know that the AEM EMS comes with a harness and an intitial MAP that will just allow you to plug and play. I'm not sure about the Haltech. Probably not. The configuration for boost with the AEM EMS is complex, but it's described within their EMS forum online. I was just looking at it actually. Do you know how much the Haltech and the AEM ones cost?

One injector and a boost controller and a Missing Link check valve is less expensive I think, but having a fully tubable ECU would be very sweet. It's not emissions exempt though and I'm not sure if the diagnostic port would still work or not?

Anyway, if you're got the knowledge (or know someone who does) the Haltech and bigger injectors should be all it takes to set up a turbo. Well, a solenoid for the wastegate is necessary too. Maybe a new MAP sensor that cap take boost too, but maybe the stock one can take a certain amount of boost? Who knows? Too many variables and too little information out there to tell you with 100% accuracy. I'm 70% sure that it would work though.

My suggestion is to get a FPR before a larger pump man. too much pressure and the injectures just won't work
