its going to be a vacum hose, check the ones by the throttle bodies and the ones that go to the map sensors check for cracked or holes on the hoses

It he's using bigger injectors with an ecu that still thinks they are stock 240's, it will run like ****, if at all.

Try to give us more info, unless uselessly short responses like "it's your timing" are what you're looking for.

killer91civic

he got one of the ecu's from turbo edit made for the set up he has . the injectors r 440 and he hase nuttin eles

Boosted Power

List the mods...that may help.

Whats up kev

Did you install all the wireing yourself? Try and check the TPS clip and MAP clips on the TB. They are the same type of clips on the harness and you might have them switched and this can cause the sputtering/no power.

yes damn good advice. ive seen this happen to a few cars, and its a very easy mistake to make

That and drop the spark plug gap down .30 isnt gonna work to well at 7 psi .. my single cam turbo is set down to .22 at 8 psi. For another EF .. best of luck

Bserieskllr

did you install a check valve on the line to the map sensor????

killer91civic

yea we did the wireing the motor ran be for the turbo wit no proublrms but after the turbo when we try to drive it it hase no power and it putters

I'm going to guess that by saying "it ran good before the turbo", you mean that it was fine before changing anything. If you added the injectors, ecu, etc and it ran, then I can't help much beyond what is already posted.

If you just jammed all the parts on at once before checking parts individually with it N/A, then I'd say do so. Back up, take the parts off, then put them on one at a time (mainly the injectors). Also, try the stock 240cc injectors again (but DON'T BOOST WITH THEM!!) and see if that is the prob or not. Flooding the cylinders with gas can create symptoms you are seeing. Double check the turboedit tune. There's absolutely NO WAY that anyone could possible create perfect ign/fuel maps for your car w/o physically being there to tune it, so the ign/fuel maps might be the problem too. One thing to understand is that any turbo setup can essentially be run w/o a turbo present, since most cruising is done w/o boost present. Hence installing each part individually and checking that it works.
