Turbo d15b7
I have a 93 civic hatch dx with a d15b7. I have already turboed the engine, but I need more fuel. I have plugged up the fuel pressure vaccum line, so it runs fine when I am at lower rpm's and when in no or low boost. What should I build fuel wise to get the fuel that I need? Also, would my engine light come on if It were to be gett6ing too much air and not enough fuel. That happenes when the turbo spools up high.

Re: Turbo d15b7
If you aren't getting enough fuel when your turbo spools you're running extremely lean. If your motor hasn't let go yet, it's on it's way. Anyway, are you using an FMU? That is what you need to get the fuel delivered under boost.

Re: Turbo d15b7
i was told to get an fmu but is that all i need? I am only running about 7 psi of boost. I'm running a TD04 off an eclipse, 1st gen. Should I get a better fuel pump as well or can I live, or should I say can my car live, without it?

Re: Turbo d15b7
Wow, did you do any research before you turbo'd your car? If you have more air you need more fuel and your ecu will only compensate for about 2 psi. You should have an adjustable FRP and an FMU at the least. Are you using a missing link or check valves for the MAP?

Re: Turbo d15b7
yah, i did research it, but there isn't much on my specific turbo and engine that tells me what i need for fuel. I know i need more fuel but I'm not too knowledgable on the exact details of what i need to get the fuel delivered efficiently. I knew that i needed an FMU and already have one ordered, but is that all I need or do I need more. My question i guess is will my stock injectors be able to support the turbo or do i need to get larger ones. I was thinking i need maybe 310's and possibly a stronger fuel pump. Just wondering if only an FMU will solve the problem.

Re: Turbo d15b7
Yeah, larger injectors are a good idea, so is the fuel pump. You never want to run lean, but running too rich will kill power. Personally, FMU's and missing links are unrelaibe. I don't know your budget, but I recomend getting a 3 bar MAP, bigger injectos and getting the ECU chipped and tuned. No FMU's or missing links or check valves. It's the best option but also the most expensive. Either way, you should read this and other posts there. It's a great site.
