Whenever I run the car and rev it up it comes up to boost fine, as soon as you try to run any boost at all it sounds like its hitting a rev limiter and wont rev any higher, guessing the ECU is cutting the fuel but no idea why. This happens at exactly 0 PSI just as the system is starting to create boost.
I'm running prelude injectors, the EM light comes on when I turn the key but goes out after about 3 seconds once the fuel pump has finished priming. Do you think thats what it is then, low fuel pressure?
ETA: Can I raise the fuel pressure on the stock pump or do I have to buy a high flow fuel pump?
Hmm, hopefully th CRX lot won't rape you, but try on there, start a new thread.
What size are the injectors (can't remember off the top of my head) ? Other than that, FPR? Or fuel pump. At least it sounds fixable.
Don't get yourself down or lose interest, more kudos for turbo-ing than just going more cc's! It'll be worth it. :twisted:
Go on to ebay and by a cheap FMU (fuel pressure regulator) theres loads of them, Yeah, I think its your problem, I used standard injectors first of all (190cc) and mine would not rev past 4k, increased the pressure and it ran really well, by raising the pressure you put more fuel in the same time frame with standard ECU settings.... basically a mechanical cheat
I'm still using the stock Honda pump with 265cc injectors, but will change it when I replace with 650cc
What have you tried and / or checked, as I have had teething problems with Fuel Pressure, Cam Timing, Map Sensor, Spark Plug Gaps, not letting the engine get to correct temperature before making adjustments Etc...
