Sup guys. I got a 92 honda civic with a d15b swap on it that i just boosted. Its a t3t4 turbo with afpr and 255 wally. I'm running BKR7Es in it too. I'm currently running the p08 ecu with no tune and stock injectors. When i go wide open throttle it boosts and then spits hard feels like fuel cut. Now i know some people in the beginning would run stock injectors for a little and be fine. What can i do? I don't have the o2 sensor hooked up at the moment either cuz i'm having issues connecting my downpipe to my exhaust. In the near future i'm putting 550s in it and getting my p06 chipped and a base tune put on it. But for right now, using stock injectors what can i do to get it to boost right and run fine?

It's because of both not having proper fuel injectors and not having a tune. Your ECU doesn't know to give your engine enough fuel, and your injectors wouldn't be able to give it the fuel it needs even if the ECU was tuned.
Don't go into boost with your car like that, you risk running lean and messing up the engine.
Using stock injectors I still don't think it's going to run fine, but at least with a chipped ECU and the right basemap it should do a lot better than it is now.
For the injectors, look around the honda-tech marketplace. You can find barely used injectors for great deals all day long.

Try adding a FPR and a missing link. This will trick the ecu.
Also use s300 in a p28 and get it tuned right!

so #2 your saying that if i just get a base tune on low psi i'll be able to run atleast decent? What's base fuel pressure should i be running at ?

for a temporay fix till you get injectors and a tune is either a Vortec or Blox FMU 12:1 and a missing link the FMU will raise your fuel press. 12 parts for every 1 psi of boost these are basic componets that come with the Drag and Revhard kits but the best would be get injectors and get it tuned

See this is just a toy car and nothing i'm taking too serious but of course i don't want to hurt it either. I have a 99 gsx that is my good car. But i love my honda and i would like it to be my street/toy car. So your saying get injectors and a basemap and i'll be good? There should still be a base fuel pressure right? Also my p06 will be fine to tune on correct? And do i need to have my o2 sensor hooked up to run correctly?

go here http://www.phearable.net/ for more info on the chipping

and yes the o2 will help tremendously on seeing what the car is doing if its a wideband o2 sensor because you are most likely dangerously leaning out and when that happens detonation occurs and i can turn your motor into a pile of scrap metal

You think i can get a base tune on a narrowband? the guy that is giving me a basemap of course prefers a wideband but said i could get away with a narrowband
