1984 Datsun Maxima 910 Project.


Recommended Posts

The B/W T5 Tranny is excellent. Every shift is like closing the bolt on a precision long range rifle. The transmission alone changes the entire feel of the car. It is one of the best upgrades I have ever done. The shift is very short, I cant even imagine it with a short throw........ and a Hurst is the next upgrade......

 

One thing I am certain of is you need to use the Amsoil Synchromesh MTF for the best performance. I have yet to find a better gear lubricant for this type of transmission.

Not much has been done in the past 6 months. I daily the car so it has just been minor maintainence and fluid changes and such. I had a radio issue so I am working on getting the stuff together to do a nice stereo in the car. I also finished the rear speaker deck which sits behind the rear passenger seats. I did it in the suede that I did the armrest inserts in. Soon going to be building the rear suspension with the AGX from a camaro. Hopefully soon going to be working on some a pretty gnarly new turbo manifold for the L28ET. And the MegaSquirt. So the direction of the car has not changed. I am just stuck in a rut right now from starting my own business, which is where all the money goes right now lol.

The car now sits just shy of 240,000 miles and runs flawlessly on a daily basis. I have about 20,000 miles on this drivetrain now and still no real issues. I got the driver side axle rebuilt now as well, so both are pretty new. I do have the problem of my driveshaft bolts getting loose over time, which only becomes a problem if I dont check them, which I do.

I cant believe I have not updated this since May of last year.

A lot has happened since then but it is hard to seem like a lot since the car is my current daily driver.......Thank god for all the work I put in over the first year I had the car.

 

The biggest thing that happened is that I was registered in JCCS this year, and I am planning on going again for the 2017 event. It was a ton of fun. I met some cool people and we actually had 4 1sg generation Maxima 910s there.

There have been quite a few upgrades in that time as well, as well as many I have planned for the soon to come future.

 

Here are the pics from JCCS ths year.

I finished the sun visors in the same black suede material of the door panel inserts. They turned out better than the picture can show honestly.

I do not have an installed picture, but anybody with an L engine needs to do this if you have an electrical system that will handle it. The Dodge Monaco CS130 alternator, its a direct bolt on once you swap the pulley and get a GM CS130  alternator pigtail. Its 96 amp output at a much lower activation speed than any Nissan BS 60a alternator. This will allow you to have great reliable power and run electrical accessories.

I plan on putting electric fans in the car before the MegaSquirt goes in (yes....I am still doing it....) and a small amp for my speakers in the car. So with the ECU, Fans, Stereo, and potentially some other items in the future like a larger better fuel pump, my electrical demands have out powered the 60 amp stock alternator.....which the car was probably underpowered electrically almost from factory anyway...........

I did a complete exhaust on the car, mild steel since I am in AZ, but all Stainless V bands. 2.5' all the way back. I do not have a damn picture. I need to get one next time I put it on the rack.

Right now my brake system is starting to go, calipers have slight seepage of fluid. And my tension rods have taken a shit......SO.......I am going to upgrade the entire brake system with Z32 30mm thick rotors and 4 piston calipers.

022_zpskgklktox.jpg

 

Maxima rotor vs Z32 rotor.

Thickness: 18mm vs 30mm

Diameter: 250mm vs 280mm

WEIGHT: 7.8LB VS 17.5LBS!!!!!!!

 

Maybe I went overkill.............Nahh..........


And for anyone thinking that............An S13 track car weighs about 2600 lb........a moderately built Maxima with no people inside is about 2800 lb.....

Also got a 280ZX master cylinder, they are 15/16 instead of 7/8 on the Maxima. The lines face a different direction, but thats an easy fix with the several flare tools I have.

The other suspension upgrade I am finishing up two parts for this week is the rear coil overs. I have been using a pair of S13 Tanabe Sustecs for a long time and they, and my top hats have started to go bad. So I designed some new top hats in Fusion and programmed them for mill to cut tomorrow or tuesday. That solves the problem of rear top hats for these cars.

Last but not least, here are some parts I built for future upgrades and for my shop, Techno Classic.

240SX 1.125 inch Throttle body spacer

Nissan L6 manifold flange with built in injector bungs.

All the machined stuff you see is completely designed, programmed and ultimately run on the mill by yours truly.

I would like to hear more about your shop and products. Do you have a website where you sell these?

 

What is going to happen with that intake manifold flange? An aftermarket intake for the L28 would be great.

facebook and instagram. Currently I only make the flange, I might make an intake for it in the future too but currently we just make the flange. We are going to make more parts for the L engines in the future too.

I finished up the top hats on the machine. the other day. I also got a piece to finish the sleeve to go over my Konis so I can mount an adjustable perch on them.

These are the clevis/heim parts I am using to make my front LCA setup. All designed in house.

I finished the rear shocks. And got them in the car. I cant believe it took me so long to get around to doing these. The car rides amazing now, its so tight.

The parts are in for the Oil Cooler. Im using the 280ZXT Auto oil sandwich plate. adapted to AN10.

I just ordered a new PS rack and quite a few other parts. Next thing I will be doing is getting the brakes and front control arms situated. Rack is getting plumbed with SS AN lines as well as everything else. Fuel system is going to come right after the suspension is fully complete in the front end.

In late April we decided to go to Nissan Jam this year. That meant I had to get a lot of the stuff done that I needed to do for JCCS except 3 months earlier!!.But there is no motivation like a deadline.

The first thing I really needed to do that had been pressing is the fuse upgrade. Like other Nissans of this era the Maxima 910 uses fusible link wires instead of modern links or fuses. The system is only rated to 80 amps on its largest link and I have now a 96 amp alternator in the car as I documented earlier on page 23. In order to do this I needed to separate the alternator from the rest of the system since it runs on a shared fusible link from factory. To do the fusing I decided to use two triple Mini ANL fuse holders.

This operation started by removing the relay box and the fusible link holder and cutting the wires back to where the alternator leads into the main harness. On our new setup the alternator will go directly into the fuse box with its own independent fuse.

When I got the loom cut open, around the back of the shock tower, inside the loom I started to see a lot of corrosion, and that lead me to finding that where the alternator lead splices into the main loom, the lead is connected with about a good solid 4 wires........which broke upon me moving the lead. So luckily I caught all this before it actually caused me an issue. Something to keep in mind for those of you still using old harnesses in your vehicles.

Here are the fuse boxes mounted up.

Here is a picture of the alternator lead itself, it uses two 8 ga wires wrapped and soldered into a ferule that goes into the fuse box. The other end uses a copper ring that mounts to the alternator.

This is the finished product mounted where the AC control solenoids used to go.

The next thing I needed to finish this year is to fis my chassis harness to EFI connectors.

The factory datsun circular connectors were pretty beat, and very corroded, so on both the EFI/MAIN harness connector and the MAIN/SUB ENGINE harness connectors I replaced them with 8 pin GM Weatherpack connectors. And at the same time I fixed the issue of the Cylinder head temperature sensor going through both of those connectors before it goes into the EFI harness. Mine now bypasses those connectors and goes direct to the EFI computer. I used newer EV1 connectors with push clips on them that do not come off. Also re wrapped the whole engine EFI harness and used a new TPS plug. At the same time I replaced all the old hoses on the injectors and put in all new injector seals to make sure of no air leaks. This is after completion of the harness rewire

I also needed all that done because I needed to do an intake/exhaust gasket and replace the freeze plugs on that side of the motor. replaced all the plugs in the thermostat housing as well as a new thermostat for the first time since I did the timing chain/tensioners. As you can see, Cylinder number 4 was a bit lean and also burning oil through the valve seals more than the others I believe. Air being the main issue which came from bad intake/ex gasket.

As I stated earlier, on page 23, I am going to be making brackets for the Z32 calipers and rotors. But to be able to drive the car for now I had to rebuild the front brake calipers, they just started leaking too badly.

Here are the calipers with new seals.

I also discovered that the rubber lines were getting a bit too old so I had new lines custom made at Parker from BrakeQuip line and ends. I did not use the wierd box style end that is used ont he maxima from factory as it is not neccessary.

The last two things on the list were to install the oil cooler and shorten the bumper sides.

 

I have had a 280ZX turbo Automatic engine complete for a long time so I used the housing from that as it is an OEM part

041_zpsuw8mo3wr.jpg

 

I wanted to be a cool kid and put it out the bumper and show off....BUT in arizona people drive like crap and are also assholes. So I decided to hide it behind the grill

042_zps3e0ds4bb.jpg

 

 

For the bumpers I decided to use the quick releases popular in the Honda world and shorten the sides. I feel it looks more aesthetic personally.
