    fuel rail return line question

    When I was installing a aftermarket fuel pressure regulator, i had to cut the return line hose shorter for fitment reasons. Upon doing so, I noticed that the hose has restrictors inserted inside the hose. I assume these are placed inside the hose for fuel pressure related reasons. Just in case...

When I removed the coilover assembly from the car, i noticed that i can pivot the top mount with barely no resistance, while the passenger side required a bit of force. When i...

    motor/engine mounts recommendation

    im looking to replace the motor mounts, but seeing how my s15 is a daily driver, i prefer not to have excessive rattling at idle. That being said, i dont need the mounts to be completely rattle-free (aka i dont want oem mounts). Im aware that nismo mounts probably meet this description, but...

    will 235/50/18 tires fit?

    I bought a set of wheels that came with tires (18x8.5 +35 with 235/50/18 front and rear). I knew from my previous set of 18's that ill have trouble fitting a 50 profile tire on the fronts, so i bought 2 tires in 225/40/18's. However, seeing how the rear fenders are deeper (plus, my fenders are...

    quick question about o2 sensors (s13 vs s15)

    I just bought a dump/outlet pipe, and it came with a s13 o2 sensor(and screw adapter) screwed in. Rather than going through the hassle of removing it and swapping it for my s15 one, can i just use that o2 sensor on my s15?

I know its common practice to relocate the wiring across the strut tower, but i think it looks ugly that way. Ive heard that you can rotate the engine bay fusebox to make...
