jdmfreak69 Posted October 7, 2010 Share Posted October 7, 2010 ok so heres the deal my lil bro bought a car off a guy its a 1996 civic ex but he has a d15b motor swapped in the motor head has two v tec solenoids and the v tec cracks around 6500 rpms and it barely pulls so im trying to figure out why there are two solenoids and why the v te doesnt crack correctly also what year the motor is and what car it came out of. the guy said it came off another civic 96 ex but i think he is full of crap. so if anybody knows anything please post here or email me please thanks email: jdmfreak69@gmail.com Link to comment Share on other sites More sharing options...
EK HATCH Posted October 7, 2010 Share Posted October 7, 2010 3 stage D15B Vtec, its got 2 vtec solenoids, but there are 3 stages: Vtec-e Normal 16 valve mode regular SOHC Vtec To further clarify things these engines used a P2J ECU, the OBD1 plain old SOHC vtec D15Bs used a P08 Read more at http://www.honda-tech.com/showthread.php?p=43603912&kcplink=1 oh yeah and they come off 1991-1995 Honda CRX Del Sol Link to comment Share on other sites More sharing options...
jdmfreak69 Posted October 7, 2010 Author Share Posted October 7, 2010 ok cause im running a 96-2000 civic ex ecu on the car right now and around 5500-6000 rpms where the v tec kicks the car kinda bogs down and slows. is that because of the ecu? \ would i just have to change the ecu to fix that and make the v tec work correctly? and would it be a 1.5 L or a 1.6 L motor????
