Good move, why not do almost everything while the motor is out and easy to work on. Maybe a new water pump ?

Don’t tempt me😉

The new timing components arrived today so might as well get them installed. I also bonded the Nissan plaque to the valley cover using ThreeBond.

A few more goodies arrived today. The first was a billet cover insert for the back of the valley cover.

The next piece was so that I can continue to run full sequential injection after I ditch the custom setup using the OEM CAS. The Electromotive uses the 60-2 trigger wheel on the crank for batch fire, but if you add a home signal off the cam it will allow you to run full sequential fuel injection. I wouldn't normally care whether it is batch fire or sequential, but the traction control works by cutting the fuel pumps so there is some concern that batch fire may leave extra fuel in the cylinder.

The current setup runs full sequential off the OEM CAS since that outputs 2 different signals, but requires a custom conversion box that is finicky on startup.

Not a big thing, but the -12 fittings for the valve covers showed up today. For now I will just use the stock PCV and hook directly to the intake manifold and turbo inlet, but I will create a catch can setup after I get the car running again.

In order to run the new crank trigger and cam trigger setups for full sequential, I have to order some shielded wire. Not too complicated, but just one of those things you have to do.

Finally got the new OEM timing belt installed yesterday after receiving the new crank seal. I went ahead and changed the idler and tensioner pulleys as well since they were 20 years old.

I waited to order the 5 SpeedHut gauges since they have a 15% off sale every March. Gauges are the same as previously shown with grey background, but I opted for the Datsun Z style artwork. Below is the artwork for the two 4.5" gauges and again mine will be grey and not black.

Got a lot going on with the car specifically reworking the wiring harness so I'll post picture of that once all the pieces arrive. In the interim, Greggs Customs sent me some pictures of the crank trigger wheel setup with the 60-2 trigger wheel. The wheel is attached to the front power steering pump pulley, which is then bolted to the damper. Below you can see the back of the power steering pump pulley machined to accept the trigger wheel.

Power steering pulley mounted to the damper with new gap for trigger wheel.

In the picture below the trigger wheel is machined so the ID fits snug over the pulley prior to any bolts being used to permanently attached.

The picture below is the setup mocked up prior to machining the trigger wheel and pulley for the retaining screws.

nice job

nice job

Yea, he does great work!

Started on the rewire of the main harness since I am making substantial changes to the setup. There are just too many changes on the setup to leave the current harness in place so I decided to make a new one from scratch. When I ditched the dash logger this eliminated the EGT's and the various pressure sensors (boost, fuel, oil) that were reduntant to the stock gauges and/or sensors used by the Tech GT. The initial task was to mockup the current harness on a board, which is about 50% complete. The remaining things to configure are crank trigger, cam trigger, knock sensor, fuel pressure, oil pressure, IAC, DFU, and wideband.

Since I'm starting from scratch I upgraded to a sealed connector. You can see the orange silicone seal where you insert the wires through the CPC.

Sweet. I'll get this trigger wheel setup wrapped up and shipped in the next couple/few days.

SWEET!

SpeedHut finalized the artwork for the gauges.

Gauges look sweet..

like your work.

^ Thanks and Thanks!

Made progress on the wiring harness and at the point where I am now adding connectors as I work from the CPC connector to the end of the harness. It is definitely a slow process, but so far so good.

The sealed connectors are such a PIA to pin because after you insert the pin through the silicone seal you then have to move the pin around to find the hole behind it. It literally takes about 5 minutes per pin to get them inserted. I ended up making a special tool to help, but it was a painful experience!

Just about filled up the CPC.

No normal fully trained GTR tech could undertake this project. Admirations plus....

Thanks, but I don't think there are any RB26 GTR techs in the USA. It's not that difficult, just initially daunting until you map out the original wiring harness. I still have to decode some of the internal wiring, but have about 95% of that figured out. Took me a minute to get my head around how the traction control was integrated into the system so I needed to make sure I didn't disrupt that feature because it works well.

There are plenty of RB26 GTR specialists in the US, just not super widespread.
