d16y8 all stock except for turbo running 7lbs, skunk2 longtube intake,fuel pressure regulator ,cold air intake, 5zingen exhaust

car runs better when at 5lbs then 7. its set up for 7 but i ease the pedel to 5lbs and she goes better. also a/f guage drops to very left and light sits at lean low side after highway driving but works around town. i'm thinking o2 sensor what about you guys. and got electronic boost guage and mechanic said i need bigger injectors because of something wit fuel pressure regulator and injectors being held open at certain boost and thats it. I need some more info about this too . need the help and have about 1000 to shop wit and can do most things

 

you need to have someone tune your car after you get an EMS or ecu socketed/chipped with the right program/maps
get a wideband o2 sensor and gauge
That narrowband is just a glorified christmas light

If not done correctly your motor will end up with a nice hole on the side or scarred internally

 

agreed, a narrow band is a waste of 30 bucks, loose the narrow band and see how far off your afr really is

 

Please tell me you are NOT boosting on stock injectors... thats a horrible idea and asking for scrap metal..

You need bigger injectors and to tune the car, and what turbo is it? because itll probably handle more than 7 psi unless its a large turbo.

 

You need the following ...

* Chipped, socketed and datalogging ready OBD 1 ECU
P05 : 92-95 OBD-1 Civic CX (D15B)
P06 : 92-95 OBD-1 Civic DX (D15B)
P07 : 92-95 OBD-1 Civic VX (D15Z1)
P08 : 92-95 OBD-1 Civic/CRX VTi/VXi (sohc vtec)
PR4 : 92-93 OBD-1 Integra RS/LS/GS (B18A)
P28 : 92-95 OBD-1 Civic Si/Ex (sohc vtec d16z6)
P61 : 92-93 OBD-1 Integra GSR (dohc vtec b18c)
P71 : 92-95 OBD-1 Integra (sohc vtec d16a)
P72 : 94-95 OBD-1 Integra GSR (dohc vtec b18c)
P74/75 : 94-95 OBD-1 Integra RS/LS/GS (b18b)
* OBD2 to OBD1 conversion harness
* Bigger injectors (440CC MINIMUM)
* Bigger fuel pump (Walbro 255hp)
* A tune

 

What he said. And thats just the cheapest route to not blowing your engine (but hell, its a y8..itll spin a bearing soon anyway) There are lots of other tuning options available as well, in addition to the socketed stock ecu.

 

...good luck

 

Hmm, Hondata s300 or aem ems 550 injectors and 255lph pump! Thats the way it should be done.

 

+1 for alpha he took the words rite out of my mouth

 

Oh and trash the garbage narrow band! Burn a hole in the piston or valve gauge! get something u can really use for a/f
