CZeroMedia did a quick video about my car at Mitsubishi Owner's Day a few weeks ago and just posted the video.

I haven't updated this. I've been too busy driving and enjoying the car after waiting almost 12 years to drive it. I've had some issues along the way with getting it to run right and handle right. Currently the motor is out for some cleanup. I'm also trying to track down an issue with driveability ...

jeffball610

Hmm. People aren't very active on here anymore. I figured out the issue. The "sense" wire needs to be attached to the charging side of the circuit instead of directly to the battery as I had initially set it up. Simple issue. It was drawing nearly 4 amps while sitting.

jeffball610

More pics to come soon, but thought I would drop a line to say my car is fully registered and passed smog in Nevada. I even got my custom plate that reads 4G6351O.

I haven't been too active on updates since it's been a lot of little things. I'm running ECMLink in speed density, but have had issues ...

jeffball610

My car is finally up and running out terrorizing the streets. However, I took a peek today and noticed that my water pump pulley seems to be wobbling. The stock pulley sits on top of the power steering pump pulley to space it out and line up with the crank and alternator pulleys. I basically made a ...

jeffball610

It's been a while since my last update. The car runs and drives. i've put about 2.5 miles on it going up and down the street. I'm upgrading to speed density this week because my MAF doesn't like how it's mounted.

Other than that, I've been taking care of "safety" items to get it certified as road ...

jeffball610

Never mind. The water pump/alternator belt came off. I didn't use lock-tight on my Jay Racing alternator bracket. I left it off for mock up and never put it on right. It should be good to go. Hopefully I"ll get some running time with it tomorrow.

jeffball610

I've finally got my car running and taking a few short trips up and down the street to get ECMLink some time with the car. Unfortunately my trips have been cut short lately due to high coolant temps. Further complicating the issue is the fact that the radiator is ice cold. My temp gauge and the ...

jeffball610

After my swap, I noticed I was getting a dead battery within a day or two even though it was putting out the required power when running. I did an amp draw test and found a 4.5 amp draw from the alternator "sense" wire hooked up the alternator "F" post. Disconnecting it gets rid of the draw, but ...

I've been fighting a mess of wires trying to track down why it wouldn't start. Finally after offering a $100 reward, a friend stopped by to help out. Turns out I had a bad connector that tested good for continuity, but wasn't making good contact with the cam angle sensor. Now it makes great noises ...

jeffball610

My CAS is good. All the testing I did helped me to understand what was going on, but the whole issue was a bad connector. The wiring tested good, but there was a bent pin that did not allow the signal to be sent to the ECU causing all of my frustration. A friend spotted it and it now runs. #4G63510 ...

jeffball610

I'm officially wrong about everything. The MPI relay was triggering just as it should. The fuel pump does not fire with the key on, only during the crank and while running. I know this because #4G63510 officially started today. It ran briefly before a skyrocketing idle forced me to shut it down, but ...

jeffball610

I can check that today. However, the fuel pump portion shouldn't matter and I don't get why it's not working would matter. Since that portion wasn't working, I bypassed it and ran the fuel pump off my ignition trigger wire. I have a separate relay near the fuel pump and used it as a trigger instead ...

jeffball610

This is what the stock system looks like
http://graph.darren-criss.org/2016/02/13/charging-system-wiring-diagram-l-b054a2eee28b7d61.jpg

The WR wire (1) is fused power in.
The LB wire (4) is my fuse panel ignition on power
The BW wire (2) is my MPI relay ignition on wire and does have 12v with ...

jeffball610

There are 2 power wires from the ignition. One is for run, BW, and the other is for start, BY. I believe you're talking about the BY wire that goes to the starter solenoid. I believe it does cut power to that part of the relay, but I still can't figure out why it doesn't work.

I had another thought ...

jeffball610

Still no responses huh?

My next thought is the MPI relay isn't functioning correctly. I do get it to trigger on one half. I have constant power and a good ground. When it receives ignition power, it does trigger the ECU to go to ground and send power to the sensors.

However, it does not trigger ...

jeffball610

Wow. 2 weeks and no one can help? I'm still not any closer to finding an answer. I did manage to do a little testing on 2 spare CAS that I have. One is a 90 and the other is a green top 91+.

What I've found:
Not much. Black next to red is ground and red is 12v. Duh. White is the RPM signal. Duh. It ...

jeffball610

I have no spark and no fuel. Fuel pump works and pressurizes the system. The engine turns over. 12v is present on all appropriate wires and grounds are good. This is what I've done to test the CAS itself:

Pins #1 and #2 on the CAS test as 5v with ignition on. #3 tests as 12v and #4 is a ground. So ...

jeffball610

Whoops. This should be a part of the "no CAS" thread.

No help huh? This is what I've done to test:

Pins #1 and #2 on the CAS test as 5v with ignition on. #3 tests as 12v and #4 is a ground. So wiring should be fine. I don't have a testing procedure for the CAS itself, but have tried the one in the ...

jeffball610

I've got just about everything done, but I can't get it to start. I have a thread in the Electrical section trying to figure out why.

I'm not getting spark or fuel for some reason. I'm trying to find a way to test the CAS to see if it's sending a signal. If it is, then I need to look at the ECU ...

jeffball610

I'm in the final stages of getting my Datsun 510 project #4G63510 running and have hit a road block. The first issue is the MPI relay not triggering properly. I might also have some issues with not getting a signal from the CAS and that in turn sending a signal to get spark and fuel, but let's ...

jeffball610

I haven't posted any progress in a VERY long time. Life got in the way as it tends to do. I've made lots of progress and hope to be tearing up the road by the end of June.

Getting some sun.

jeffball610

LOVE this project. My 510 project is on the back burner right now, but I hope to get back to it next month.

Those PR guys love classic Japanese cars for drag racing. Info for their cars might be tough to come by, but there should be plenty of examples to learn from. I'm looking forward to seeing ...

jeffball610

I've been following this build on Facebook and love the attention to detail. I'm hoping someday I'll be in a position to own a Starquest along with my other projects.

That's an interesting oil pay you have. Is that a RWD pan from a MM/D50? I'm thinking I'll need a different oil pan setup for my ...

jeffball610

Bill is a stand up guy. He has lots of projects on his plate and if you were neglected, I apologize on his behalf. It sucks you had a bad experience, it happens in every business, but don't go smearing someone's name through the mud over one experience. You can choose not to deal with him again, but ...

jeffball610

Sweet, well thought out project. I'm excited to see the outcome. Looks like it's pretty close.

jeffball610

$500 is too much in my opinion unless they're including all wiring and accessories. You could probably find a running car on Craigslist for $500. There isn't much need to magnaflux a 4G63 unless it's beat to hell. They are tough motors and I haven't seen one with cylinder cracks or major issues to ...

jeffball610

Bill shared this on Facebook. I think it makes sense now.

The "S" side is hot all the time from the fuse, then the ignition switch powers up the "L ...

jeffball610

This isn't much help. Why are there so many different diagrams for the same thing and why can't I find the one I'm looking for?

jeffball610

Progress has been continuously halted by the confusing wiring process. I was working with a 95 Accord fuse/relay panel, and things just weren't making sense. Very little information exists on how to make it work with other vehicles. So I scrapped it and got a 2G NT fuse/relay pane (same as turbo ...

jeffball610

I promised some updates, and then forgot to post the small one from about 3 weeks ago. I finally got the fuel pump mounted in the stock tank. It's a Walboro 255lph on a Z31 fuel pump mount.

In hindsight, I should have ...

jeffball610

I'm back! Just moved into a new place with a garage a month ago and getting things set up. Updates WILL be coming soon. Wiring is the first order of business. It's been 2 years without my car. I will have this thing on the road by the end of summer barring any major disasters.

jeffball610

Sucks about the motor. On a brighter note, this should be basically the same swap that I'm doing to the 510. Check out my build. Hopefully it will answer some questions for you.

jeffball610

Just putting some info out for everyone being a recent 350Z owner.

The 03-early04 transmissions have weak synchros on 3-4-5 gears. Used 04-06 transmissions go for about $1k, but a NEW unit can be had for $1800k from Nissan. The 07+ is a different bell housing. However, the internals of all of these ...

jeffball610

Yes, a 2.1L is a 4G64 block with 4G63 crank. (2.4L block/2.0L crank) There is a stamped number on the block just under the water pipe near the water pump. If it's a 2.4L block it will be stamped as 4G64.

But if the guy is saying VR4, then it's likely a 2.0L JDM or USDM Galant motor. Those were only ...

jeffball610

The bolt hole on the trans that doesn't line up is probably due to the 7 bolt vs 6 bolt components. 2G motors moved their motor mounts to the transmission, so there was a little more on the bell housing portion.
You shouldn't have to worry about crank walk with your engine. It's still an issue ...

jeffball610

I guess I've been mis-quoting my own diagrams. The BG wire goes from the MPI relay to the fuel pump and sends the required voltage. The BW wire from the ECU simply monitors the voltage. But from what I can gather from several sources, the MPI relay and ECU cannot handle the amperage draw from the ...

jeffball610

Bill, I understand the injector circuit in the ECU, but it doesn't perform the same way as the fuel pump from my understanding. I'm assuming that enough power gets to the fuel pump and I won't lose any performance by leaving the wiring system as is. At a later time, if it becomes necessary to run a ...

jeffball610

Well hell. Now I'm thoroughly confused. Then how do any of the stock items work on the DSM? I know there are several items that run on 5v, but many of these items run on 12v. (the coil for one) And I don't see how the ECU is grounding out most of these items. Especially when the wiring diagram ...

jeffball610

So I guess the real question is can the ECU send enough voltage AND amperage to the fuel pump without a separate relay?
I've looked over that, and many other wiring diagrams several times and there is nothing to lead me to believe there is a separate relay or wiring system in the stock wiring. The ...

jeffball610

Thanks for the response, but it doesn't help answer the question. I know the original 1G stuff was meant to increase performance over the stock wiring. But I don't know if the ECU is sending out the same voltage I can get from running a separate wire. I'll keep searching and see if I can get an ...

jeffball610

Sad face for no responses.

jeffball610

Well, I'm getting to that point and need some clarification. I thought the BW wire from the ECU and MPI Relay sent power to the fuel pump, but I want to make sure I'm getting enough power. The old DSM trick was to put a dedicated power wire to the fuel pump with a relay near the pump. Is this still ...

jeffball610

Holy shit! Has it been that long since I updated this build? Guess I've been posting progress of individual project areas and not on the build as a whole. Well, here's the fuel lines I've been working on:

Great project. But I also wish your pics were bigger. It's great that someone with your experience has joined our small community. I'm sure we'll learn a lot from you in the future.

jeffball610

So I've posted my progress and troubles of bending up new fuel lines for the 4G63 510 project and thought I would share all of my findings here.
First off, bending 3/8" fuel line isn't that hard, but it takes some effort. First thing you need is a tubing bender. (duh) Everyone says to go out and buy ...

jeffball610

I personally think the front end looks to long and "heavy". Maybe you can move that grill back toward the motor more and possibly section it to be smaller. I know it's a lot more work, but I think it will look much better.
Other than that, I think the front end looks cool. Keep up the great progress.

jeffball610

Keep reading the forums. Most of your questions can be answered in detail. But here's some quick answers:
Pick a block and go with it. If you really want the FD trans, make sure the motor will clear with the trans in the stock location. The biggest firewall fitment issues are the cam angle sensor ...

jeffball610

In case no one has seen it yet, Bill is mentioned in the April 2012 issue of Modified magazine for his bellhousing adaptor for a 4G63 S2000 build. Hopefully one day he'll get some more publicity for his work with us here on the forums.
Bill, you're awesome!
