dpfi upgrades? (without mpfi conversion)

[turbo93impreza]

i want to keep the dpfi intake on my 89 dx, but i want more fuel for a low boost turbo.

i dont want to run the risk of screwing up the mpfi swap, as i need this car on a daily basis. also the cost would probably be lower, which is always good . i'm good at fabricating stuff, and i just need to know if there is anything out there i can do. i know that you can just plug in larger injectors into the mpfi, so is there anything that will plug into the dpfi?

what about just getting a pressure sensor that will activate a 3rd injector when on boost? that would save gas as opposed to the larger injector route. i guess i could either run one injector at static (wide open) when ever the car is on boost, and just plumb it in before the throttle body or right after or something (this would also be crazy easy to wire up). or i could run 2 smaller injectors and have one run at the same time as each of the larger ones (splice the wires and run them paralelle).

Any ideas?

okie well you dont wanta mess with MPFI yet you feel ok to boost your car? i mean it can be done but MPFI with or without boost is easier. Not too sure bout other things though

You actually have the best of the best for the DPFI. There is no other plug and play items you can do it with. Unless turbo or some other little gadget that I have no clue about. Personally, the MPFI swap is the only way you'll ever see the greatest improvement for the D15.

this is how one guy ran a dpfi turbo setup.

what about running a 3rd injector 100% duty cycle (static) when ever the car went into boost?

how about forget the 3rd injector or turbo. put in a 75-100 shot of nitro and blow that engine and get a new one....... i swapped a zc in, in 3 days so i didn't have my car for a weekend and monday.

i'm with Ace on that one. more power to ya if you want to turbo a DPFI d15. however, that doesn't make sense (to me) that you say you're good at fabricating and you want to hook-up turbo but are afriad of messing up MPFI

check this link out...Good MPFI info

i'm better at piping than wiring, simple as that. i just havent had good luck at it.

not to mention the added cost of buying the manifold, computer, blah blah blah....

i can make my own citcuits, such as one to run the injector, i just dont like making wiring harnessed etc.
