Fantastic job, exactly the owner the car needed.

Looking good! I like the wheels a lot. 8)

Awesome

Looking good. Did you pull the bleeder screw all the way out on the clutch slave cylinder? We have found that the clutch is many times overlooked when the folks flush the brake fluid and it will build up a lot of crud inside. Often we will pull the bleeder screw completely out and clean it to make it flow correctly.

Cheers,

Those wheels are PERFECT. Love love love.

Thanks for the nice words everyone.

Hi Jim, I did not. I will try that tonight. I do have an extra brand new brake bleeder screw. Does the clutch master use the same bleeder? If so I'll just swap in a new one. Any idea why the master is squeaking ? Thanks again for the help!

I rebled the clutch master and my problem before was that I was not pressing on the brake and clutch pedals at the same time, tried that and the master bled fine. Thanks!

Also I'm having a little issue with the motor not pulling like it should. I tested the throttle position sensor and partial throttle reads the correct resistance yet the full throttle position is not reading correctly. I'm going to replace that and see what happens.

Also I feel like I'm getting a little dieseling when shutting off the motor. I check the temp sensors at the thermostat and the one connected (in the photo, pointing towards the rear of the car) had bad wires and I think we're shorting on each other. From what I have read, the sensor should start at some resistance and go to 0 as it warms up. If the wires were shorting then the resistance would never go to 0. So I soldered new wires in to fix it.
In regards to the temp sensor on the other side (towards the front of the car), the wires broke off of it. I believe this in for an electric fan only (which I don't have) yet I'm wondering if it's wired in parallel with the rear facing temp sensor. I have a three prong plug disconnected in the photo below and I'm wondering if it should be plugged into the forward facing temp sensor???? Since the wires going to the rear temp sensor are wired in parallel to that three prong plug, the ground is never connected to the rear sensor making it useless. Can someone clear up where the three wire plug should go (see photo) and also what the bundle of three wires go to (this bundle is just cut and I don't know what plug is supposed to be on the end of it)

The three wire colors are black, brown/black, and green/black

Thanks!

any one?

Hey there, so I am looking for the S14 owners for help on this next issue. After driving the car a bit, I am noticing that the engine seems like it doesnt want to rev quickly. I hear a lot of noise from the front of the motor which appears to be the fan/waterpump? It sounds like a fan would on a hot day, some call is the bus going up a hill noise. The temp gauge is showing normal temps and is right in the center. I did the newspaper test with the fan clutch and it seems to be okay. I am mainly looking for suggestions. I will note that the fuel pump (next to the fuel filter) does tend to buzz pretty loud sometime and is good other times. I just had the fuel injectors rebuild and bench flowed (all looked good ). Please help! I want to enjoy the s14 without being concerned.

Can anyone explain to me how to check the fuel pressure and troubleshoot other parts of the fuel system?

thanks in advance!

[bootlegskate]

I tested the fuel pressure between the pressure regulator and the fuel rail, its measuring at 78psi when I pinch the hose before the fuel rail and fuel pressure gauge.

I tried to move the fan clutch and there is a little slop in it, maybe moves 1mm front to back.

I removed the power connector to the in tank feed fuel pump and it didnt seem to sound differently so tonight im going to run +12V to the pump with the car off and see if it makes noise.

Also I just realized the car has an innovate LC-1 wideband, after reading up on it, it appears this unit requires recalibration about every 6 months. I am going to confirm the wiring is correct and then recalibrate.

still trying to figure out why the slow rev speed/power.
