Filled up the tire that has a slight leak. Was down to 7 psi after sitting for 6 months. Prepping some 15 x 7 alloys to replace the 15 x 10 steel rims for daily driving. I figure cutting well over 100 lbs off of my wheel weight will help mileage and power... also continue continued to tear down my old rig. Today will be dismantling the front end to reclaim my 2wd steering mod parts and steering damper/idler arm brace as well as any other goodies to swap over to the new rig. Also going to throw a battery into the old truck so I can run a compression test on the vg33e swap to determine if I should rebuild it before swapping it into the new truck. It's going to need to be healthy to handle 15 psi or greater worth of turbo

So nice! Very cool rig. I'm jealous that you guys get them made into the 2000s!
-
Thanks for the advice.
My circuit uses 4 of the digital outputs of the arduino to signal a separate 4 channel relay driver. I'm using relays to control the Solenoids (Shift A and B , TC Lockup and the over-run clutch. This gives me enough power to drive the solenoids while the arduino remains at 5volts in/out.
Once I finalize the complete circuit setup and run it for a bit, I'll post up the specs.
very nice! Small relays will work just as well as transistors. I'm excited to see your results!

When you checked for parasitic drain, you detached one of the battery terminals and then placed an ammeter set to the milliamp range? There must be a drain if your alternator tests good (should be over 14 volts measured across the battery terminals when the vehicle is idling), and your battery is new..

P.s. one option may be to send in the injectors to be bored and reworked. I believe most injectors can be reworked to a higher cc rating. There are a few companies out there that do it. Might be an option if you are having difficulty finding over sized oem replacements.
-
My bad. I was unaware z31 used top feed injectors. I can for sure say however that z32 and q45 use 370cc side feeds.
-
I'm interested in this as well. The vg30 and vh45 injectors are 370cc. I believe they are the fatties as well but that will have to be confirmed...maybe check the z31 boards? Those guys would probably know better of different oem options for vg3Xe injectors.

^^ pics!!
yesterday was a very busy day but today I'll have time snap some pics of how she is sitting now.
-
Right on! Glad you got it all fixed up. Always a nice feeling when it all works out, eh?
-
Just mounted the 33 x 12.5 x 15 tires and 15 x 10 wheels on my new black pathy. Got a guy coming over to buy the 31s that came on it for 500$.
and not on my pathy but I changed the slave cylinder on my 240sx...have a clutch again yay! -
I know how it is man. Good luck!
-
Neat. Keep posted on how this works out. I've got an arduino 2560 mega board that I've been playing with lately. Really cool devices. I would say it is a good idea to keep the stock tcu as a failsafe though like you plan, since the arduino boards are not industrialized pieces of hardware they will probably not stand up to the abuse and vibrations of life aboard a 4x4 truck. Build a nice dampened enclosure for it though and it should last a while!
also my advice is to go through the transmissions harness with an ohmeter to determine the resistive/inductive loads of the solenoids etc so you find out the source current needed to drive them. I don't think the arduino will be able to source enough current to drive the system. You will probably have to build a transistor array and use the arduino just to drive the transistors to saturation and control the logical side of things. Tip31/32 power transistors might work for the job. I believe they will drive 1 amp without heat sinks and generally you want to run a transistor at 50-70% of its rated current throughput.

What I usually do is attach the two heater core hoses to the upper plenum first when it is detached from the lower section. I eyeball how they need to go orientation wise to be close and I make sure that the clamps tangs are facing in a direction that I will be able to get at once I slide it down into place. I then use my set of long needle nose pliers with varying bent tips (one is straight, one is at a 45 degree and one is at a 90 degree angle) to reach down and quickly loosen the clamp in place so I can maneuver the heater core lines onto the heater core end.
Placing those tubes to the plenum after it is bolted down in place is a pain! I have also done that too but it is MUCH easier to attach them to the plenum first, before you place the plenum back into place. I've pulled and replaced pathy plenums 7 or 8 times now and i assure you the first time is definitely the hardest ! Long needle nose pliers are key!
-
Jeez. Must have been quite the impact to bend a rim, steering and cause damage in the engine bay. Glad you are okay man!
-
Got t-boned in it...these things are tanks. Though she will need repairs.
No injuries I hope? Vehicle accidents are never fun.. Hope you are okay!
On another note, I ordered some silicone couplers today to build my custom intake. Going to be running the vg33e intake manifold and throttle body, 2.75" pipe for the intake to match the throttle body, 2.75 to 3 inch couplers to adapt the N60 maf(inside diameter of the maf is actually near 2.75" when the center element restriction is taken into account), and then replacing the current 2" snorkel pipe with 2.75" snorkel pipe. I'll definitely post pics of the setup once the parts show up!
I also took some measurements for a sleeve that I need to machine to finish my custom throttle body setup.

A really nice trick for testing injectors on a pathfinder is to use the injector harness plug. The fsm states which pins relate to which injectors and from there you can ohm out all your injectors in a matter of a few minutes while only having to unplug one connector at the front of the truck. Can't remember off the top of my head which one it is, but if memory serves it is the connector with the many small pins (I believe the largest one in the cluster of 3 plugs at the front of the passenger valve cover, where the injector harness meets the main engine harness).
-
Nissan oem manifold gaskets are the best I've ever used although not as cheap as the parts store variety. They are layered sheet metal and seal very well as long as you have good studs.
-
Looked at it.. about to install an N60 maf.
-
That looks really clean cd n _ s4.
I just started thinking about this too... about to start my ham radio training course!
-
Keep it coming! Love this build. One day I would love to long travel IFS my pathy but keep it 4x4.
-
Yes I do all of the board work and programming myself. I am a certified electronics technician as well as an automation technologist so it's a bit more than a hobby for me!
Pm me for rates if you would like your ecu socketted and chipped! (No they do not come socketted from the factory, although that would have been nice! Haha)
-
Hahaha. Well i don't know about most powerful ever; but I do have an LSD.
I may be able to claim that title once the remote turbo setup is finished though! Lol17 psi worth of boost will sure make it feel like a different beast! Another of the fun things in the works.
-
Got the 92 ecu socketted and running on a modified tune. 95 pathy fuel and timing maps. Runs great. Next will be to wire up the N60 maf and plumb an inline air filter to my snorkel.
-
Yep. Going to be running the n60 maf as well as modified fuel and timing maps on the 92.
About ca smog. You can still modify the tune to run the n60 maf while retaining the factory fuel and timing maps. This would allow for a higher over all power (with supporting mods of course) without changing your emissions values significantly.
I feel for you guys down there...those are some strict emissions laws! The sad part is, it's the diesels and heavy machinery as well as production plants that are causing the majority of the pollution. This is what was found in Vancouver and they are now eliminating passenger vehicle emissions testing and moving the tests to commercial vehicles and heavy equipment, since passenger vehicles only account for a single digit percent of the overall emissions of the city.
People finally realized it's just a cash grab!

A turbo ka24de would be awesome in a pathfinder. They are very torquey from the factory and are also efficient. Now if any 4 cylinder was going to make it into a pathfinder, I think that should be the one. 155 hp and 160 lb ft torque from the factory. Easily obtainable 275 wheel horsepower / 300ish lb ft torque with a moderate turbo setup around 10-12 psi depending on mods. Now that would be a fun and efficient pathy!
