If money is the root to all evil we need to get rid of it fast like this gentlemen here. I kid.
UPDATE on HEI:
Unfortunately I was unable to get my HEI swap running correctly so it has be postponed until I can determine what to do.
According to some hybridz.org members, my diagram is correct. I think there may be some wiring that needs to be done on the old transistor ignition side especially for the 1975 Datsun 280z (california model). It could also be that I blew my coil during the process. I’m not sure So after failing to get that going I decided to just revert back to stock… for now.
After going through my intake manifold recently, I noticed that my fuel injectors were in critical condition. All of the pintles on the fuel injectos were cracking. It would be very bad if one decided to crack into my combustion chamber. Considering I still have a loss of power at higher rpms, I figured that maybe its tired fuel injectors/fuel pressure. So I bought some good condition “newsed” injectors from a Hybridz member.
Pic (not some are getting prepped so are not in the picture):
As I was removing the injectors I noticed some already cracked. I’m so happy I bought newsed ones. Yikes.
New ones in:
I was messing around the other day and test fitted some headlight covers that I’ve had for a while on the Z. Not sure how I like them.
I have an HEI install on the way. Hopefully, this covers my loss in power at higher rpm. I may be out of ideas after this… Look for an install post on that soon.
Also, I did some shopping recently. Its on TOP SECRET access for now. I’m excited for more posts on this later.
When you start your Z do you get a clicking noise coming from your starter but the car doesn’t start? This is the simple mod that will fix that. The clicking noise is from the starter activating but not getting enough juice to spin. This can be from old wires or corroded connections. The Z’s used the ignition switch to activate the solenoid for the starter. Using the relay mod will ensure that the solenoid gets a solid 12v every time the key is turned. I found this mod on XENONS30(John Walker) and I give him credit for most of the thinking on this project. Check out his site.This mod can be done for less than $5. Besides the relay, I had most of the materials laying around.
The centerpiece of this mod is a 4 or 5 prong relay. I bought a pack of 5 30/40 amp 5 prong relays off of eBay.
- 30/40 amp relay
- 14 gauge wire
- Electrical connectors(I used an assorted kit)
- Wire cutters/stripper
- Electrical tape
- Hand drawn Wiring Schematic(made connections easy)
- Disconnect the battery
- Find a good mounting place for the relay.
- Run a 14 gauge wire from the (+) side of the battery to the “87” connection on the relay.
- Run a 14 gauge wire from the solenoid to the “30” connection on the relay.
- Run a 14 gauge wire from the wire that originally was connected to the solenoid to the “86” connection on the relay. This wire is to the ignition switch.
- Finally, run a 14 gauge wire from the “85” connection to a good ground.
- Tidy things up. Re-connect your battery and start it up!
Here’s a close up of my connections at the solenoid and ignition switch:
This mod has been great for me. The Z started instantly and has been doing so since I did this mod. Great stuff!
Went to a meet tonight saw a lot of cool cars and met some cool people. There were a lot of crazy 510′s and of the 4 Z’s (mine included) 3 were AMAZING(hmm which one was the bad one??) . There were some Toyotas that came through, along with an old school Mini Cooper.
I didn’t take too many pictures. Here are the ones that caught my eye.
Pristine 5 Speed Toyota Cressida. On Hoshino Impuls.
Rotary swapped 510. Completely Overhauled. Clean clean clean. and fast.
I was talking to a Z owner and I noticed his stock-looking Z had a swap. RB20det. upgraded Turbo and bored to 2.2 liters. This thing is FAST
Then there was this. It was the first thing I saw in the parking lot as I pulled up. This Immaculate white 240z. Just the right amount of drop, Just the right amount of wheel width, just the right amount of modernization in the interior. A white whale If I should say. There she blows!
It was a cool event and I’m looking forward to some of these later in the Spring as more people will be willing to bring their cars. Look for more posts about meets and events later.
I realized that I needed a catch can when I opened up the intake manifold and saw the thick layer of sludge that lived in there. For time related reasons and in trust of quality I went with a Husky water/air separator filter from my local Home Depot Market. It set me back about $60 +fittings, but because of its filtering abilities and detachable chamber I went with it.
I rerouted my main engine harness and used the two grabber hooks there to hold it in place. I ziptied it there for good measure as well. Here is the final mock up and position of the catch can:
Arrows show locations of the new catch can system:
Next step may be some more tuning but for the most part its done until a full engine rebuild! o.o
We shall see.

Good News/Bad News…
Good: Runs better!
I have eliminated the large amounts of back fire, the engine bay looks much more orderly, and improved the overall smoothness of the engine.
Bad: Not fully fixed.
Still hesitates when pushed hard (heartbreaker!), the engine burns oil, and it doesn’t backfire like it used to.
>>Next Post is on Catch can!!
