    It's the pin 86 not being continues with the dual press switch and pin 85 not having a ground is what's preventing the a/c controls to turn on the condenser fan. And that also explains why the condenser fan only goes ON when ECT is higher and...

    When the vehicle reaches operating temperature and commands the cooling fan to go ON, it is normal for the condenser fan to turn ON as well.Going back to all 4 wires having continuity with pin 87. This could be a normal phenomenon for pin 87 to...

    Pulled all the relays out this time. Found the relay where the 2 rad color wires have continuity with pin 87. Also found that all 4 ground wires between the 2 connectors have continuity on pin 87 for a separate relay. Not sure what the relay goes...

    All right so I finally got all the stuff in and I swapped out my fuel filter and my spark plug wires with ngks. I did not get new spark plugs because those are new already. I also checked the ohms on the coils through the plug and both are...

    Just did another test where I pulled the compressor relay and left the fan relay out too. All 4 ground wires between the 2 fan connectors all had continuity with pin 87 of the compressor relay ONLY

    @Vladimir You're not going to believe this. I got curious due to the conditions at which both fans kicked on so I thought "maybe they share some part of this a/c fan relay". And boy do they HOWEVER, the wires don't make sense. Just like the a/c...

    Alright so I checked the 2 black wires and they do have continuity with chassis ground whereas the blue and orange wires do not.Can I use the power probe to just send 12v to pin 87? Do I need any ingnition or can I do it without even putting...

    It is too damn hot to work on this car. Head is back on. Parts keep going back on. I guess that's a good thing. It will run this weekend.

    I did the relief and smooth out the oil gallery on the block for the front case housing, I also left in the squirters and I run 10w-40, I’m on the looser side of the factory tolerances.My oil pressure has never been better, traditionally always...

    ty for reply. hmm well i might have to try without the port first and see how it goes on the initial break in, hopefully no crazy psi during my first cruise and go from there. I have the pump gears packed with petroleum grease, lots of assembly...

    Cyclic Idle/ Anti Lag -In this section, we will cover implementing cyclic idle using a cable-driven throttle. To have an efficient setup, you will need to have a DBW throttle or a throttle kicker. Since I do not have an ISC, I will not touch...

    I didnt bother porting the relief valve when I did the BSE kit. I can't say that I noticed much difference, but I don't have an aftermarket gauge either. Also stock build. These 4g engines don't have a lot of oil pressure to begin with.First...

    Yes, also my first time ever racing at the shootout! I usually drive my X from Buffalo for the last 10 years or so and decided it was time to start racing, and man I'm so glad I did!

    Thank you! ACT 2600 6 puck. It's old and does need replacing. I don't think the car needs a twin disc just yet. Considering a Comp stage 4.
