i have a 92 civic hb with all wires ran for vtec and everything problem is my engine wont rev to its potential. my setup is as follows

8:5:1 srp pistons
tunertoy h beam rods
b16a3 head
gsr timing belt/ waterpump
arp headstuds

my timing on my car is right on but when i take a timing light on it it says the timing is off a tooth or so. my car runs fine and everything. it doesnt like to start up in the heat.

if someone could help me with my redline problem plZZZZZZZZZZZZZZZZZZZZ!!!!

the car actually redlines at 6500rpm. there is no knock sensor but i dont believe that would cuz this drastic of a problem

 

You do have a LS/VTEC kit right? Also what computer are you using, any codes?

 

Yes i'm using the LS/VTEC Kit and i'm using the JDM P73 ECU. The CEL is on but I don't know how to check which codes it's throwing. But AFAIK it's the CEL for the 02 Sensor.

EDIT: Actuallyy I know how to check it but I forgot all about it. I'll go do that right now.

RTFF - read the ****** faq

 

Okay I definately can't find that plug to check the codes. I know what your talking about because I can always find it in my Accords. But when I try to find it in a friends Civic it's nowhere to be found?

 

jdm p73 is obd-2 and if you are throwing a code, then its gonna be in limp mode and not let you redline the car. why do you have a p73 ecu in a 92 hatch, why not get a chipped p28 or something

Same thing I was thinking.

 

Okay actually.. I found that damn plug. The description in the FAQ is wrong about the colors thats why I was confused. But none-the-less I figured out the problem to my friends car. He posted it up looking to get the answers and I researched it on here and found it.

He bought a kit from rywire to wire in vtec and the o2 sensor and him or another one of my buddies wired the D6 pin (VTEC Pressure Switch) to the empty D5 position. We changed it last night, and now he's just throwing the code for IAT and the o2 sensor which we're going to fix today.

It revved to the max potential of 8200 and it hauled some major ***. Thanks for all the help guys. If he runs into another problem i'll check back here. Later!
