OK, here is the inportant mods on the motor: B16 head with .15 milled and PnP on intake B18a Block with .10 redeck Pr3 pistons JDM ITR intake man. Erics Racing 70mm throttle GSR Fuel Rail 96 LX Ruel Line Stock LX injectors -(tell me if you need more mods listed) Car is 96 civic lx lx harness repinned 96 JDM ITR ECU **No CEL Codes** OK, Here is the problem: Motor starts up ok but revs up to like 3k roughly and revs down then dies. Does this about 3-4 times then will start up, but idle rough. Motor will idle rough, then when ecu kicks in (slight bump in rev), motor will idle smooth. Here is my problem, when I go to give it some gas or throttle, the car will die instantly. If done really slow, motor will rev up slowly then die, but if I close the throttle quickly, the motor will jump back alive again. I have an air/fuel gauge installed, when giving the motor gas, the gauge will read rich then make its way towards lean untill the motor dies. If I open the throttle really fast, I can hear the motor suck air like madd (Really loud), then as if it choked and dies. My concluson for tonight: I am assuming right now that the fuel rail and the fuel line are not compatible with each other. Thus killing my fuel pressure leading to my problem. Why I say this is my LX fuel rail is similar with design function except for one thing. Where the banjo fitting on the fuel line fits over the fuel rail, my LX unit has two holes accesing(sp?) the fuel rail. The GSR unit doesn't have any hole, instead the nut that bolt the banjo to the fuel rail is where the fuel enters the fuel rail. I figure that the fuel line is the problem here? I am still open to suggestions, but if anyone has experienced this or similar, please do tell what you did .
