  1. Update time. Been a long while since I did some work on the maxima, but had some spare time in the last month or so, so I did some work. I dropped the transmission to do a clutch job and replace a failing throw out bushing, and while I was at it, took some measurements and documented information regarding a factory 5 speed behind a ld28. I posted alot of information in this new topic I posted in the general forum. A TLDR for anyone who doesn't want to read in that topic. A factory 5 speed in a Ld28 maxima, uses a 225MM Pressure plate and clutch off of a standard 280zx, but uses a SPECIALTY throw out collar. I found that a non turbo 1990-1996 300zx collar is similar looking part with VERY similar measurements, shown in this photo (Silver marking are 300zx measurements, black is old maxima measurements) I did not use the 300zx collar, because I did not get it soon enough to compare it side by side, so I used the old collar with a new bushing. I learned that the manual Maxima uses a clutch damper, very similar to the clutch damper used in the 90-96 300zx, and is a common part that is bypassed by the 300 guys. In fear of the part failing after 230,000 miles, and a replacement part from the 300zx costing 150$, I chose to bypass it as well. It was a simple procedure, reusing one of the lines off the damper, a 10mm brake line union, and a longer soft line from the front brake hose off a 620 pickup. It also lead to MUCH nicer clutch feel, and actually has a clutch feel to it now. This is the crossmember off of my 82 maxima. AFAIK it looks to be a maxima specific designed crossmember, utilizing a 3 piece design. NEW shifter bushings FTW!! While the maxima was in the air, I also replaced the rack and pinion with a rebuilt one off of rockauto. One of the problems I ran into was the rack and pinion mount bushings. I couldn't find anything online about the bushings, and took a gamble and bought a set of 280zx poly bushings and HOPED that it would fit. And I can confirm, it DOES work on a maxima. Poly bushings are a PITA to install with a power steering rack, but it is doable. One bolt at a time, and a large pair of grips to "compress" the bushings to install the mount was necessary. While installing the rack and pinion, I upgraded the inner and outer tie rods. I had issues with the stock s13 inner and outer tie rods, where I did not have enough threads on the inner tie rods, which lead to too much toe out. I bought a set of GKtech M14 SUPER ADJUSTABLE INNER TIE ROD, which is 70mm longer than a stock s14 tie rod, and has more thread length. I chopped them to length, used stock S14 outer tie rods, and now I have proper alignment! I may upgrade to adjustable outer tie rods in the future, to get rid of bump steer. If you go this path, you must use s14 outer tie rods, which are m14 compared to m12 of the s13.
  2. I'm writing this topic for anyone who is in need of some information regarding a factory 5 speed in a maxima with a ld28, and I am also writing this to see if anyone else had any information for this application. I dropped the transmission in my 82 maxima due to a failing throw-out bearing, and took my time to measure and document everything specific about a 5 speed behind a Ld28. I have a early 83' FSM that has diesel information, but is VERY lacking in information about the 5 speed options with a diesel, so I had to do alot of digging, and basically came up short. So below ill show everything I had found. In the FSM, the Ld28 backed with a 5 speed, has a 225MM clutch and PP mount flywheel, specific for a LD28 (thick ass flywheel). AFAIK, any ld28 that is a INDUSTRIAL or boat engine, comes with a flywheel with a 240MM mount and clutch surface. (One of my spare ld28's was a industrial engine, possibly boat, and has this 240mm flywheel) I removed the clutch and PP off of my maxima, measured it, and found it to be the exact same dimensions as a stock 280zx 225mm clutch and pressure plate. If a LD28 manual uses the same clutch and pressure plate as a 280zx, but has a thicker flywheel, that makes the throw-out collar a SPECIALTY part. Here are the measurements of the throw-out collar that came off of the maxima, and I could not find ANY information online about this specific throw out collar. After ALOT of digging, I found that a throw out collar from a 1990-1996 NON turbo 300zx is a very similar looking part. So I ordered a NOS collar, and measured it as well, to find that it measured VERY close. So close, that it might as well be a "superseded" part from nissan. (The silver marker is the 300zx Collar measurements) The design of the part is different in some areas, but I believe the part is close enough to work, or can be modified slightly if need be. I re-used my old collar, with a new bearing as I did not get the 300zx collar quick enough to do a side by side comparison or use the new collar in the car, but may try it later. I do not own a 82 maxima Parts catalog, and cannot find anyone who has one, so finding the actual part number for a 1982 maxima diesel 5 speed throw out collar, is basically impossible. This is the closest I could find so far. Here is the transmission mount that came off of my diesel maxima. Its a complicated 3 piece design, that is kind of similar to the 260/280 and 280zx 2+2 crossmember, but uses more parts. It uses a standard transmission mount, attached to this specialty dual bushing crossmember. If anyone knows of any other model that has a similar crossmember, I'd appreciate the information, as I'd love to get new trans bushings. This is the middle driveshaft and carrier bearing/bushing off of the diesel maxima. Clutch hydraulics! The Maxima diesel with a 5 speed utilizes a Clutch Damper to "soften the clutch feel" and is a part that is NLA AFAIK. The 300zx (z32) uses a very similar looking part (It could be the same part) but is about 150$ new from Nissan. It is commonly bypassed by the 300zx group, due to it failing, or for a better clutch feel. In fear of it failing after 230,000 miles, I also bypassed it. It was a very simple procedure, using a 10mm brake line union, reusing a line off of the damper, and a longer soft line from a front brake hose off a 620. If anyone has any other information regarding a 5 speed diesel maxima, please post here for anyone else who may be in need of information. And for me please 🙂 This here is a question to all of yall. Has anyone on here used the superseded throw out bearing part #30502-69F10 in their datsun transmissions?? This is the superseded part of the old Nissan throw out bearing, and the design of the part looks to be different than the old bearings. Id prefer to stick to Nissan factory parts if I could.
  3. Yessir, the sedans came with IRS, similar to the 280zx it's, if not the same suspension. Also came with power steering rack and pinion, and 4 way disc brakes. The wagon came with a standard rear axle.
  4. I think that Nissan's plans and thoughts were, back in the 80's , was that with the rising scene of high luxury, technology stuffed cars, Nissan needed a luxury family car to go along with their line up of cars. They had the sports car (280zx), the economy cars (510 V2, 210, 200sx) and their updated truck (720). They didn't really have a 4 door luxury car at the time, so they took what they had from Japan/Australia, the 810/910 bluebird, and modified it to cater to the American Market of the time. They added electronic add-ons (factory Power windows, sunroof, Nissan sound system, bigger, plushier interior, Independent rear suspension) Nissan most likely also modified the chassis to accept the l24E and ld28 to make the maxima line more luxurious as well. A big engine for power and comfort, that also provided good economy. Or at least that's what my guess is to the reason as to why Nissan made the datsun maxima in the U.S in the first place. Nissan didn't make or sell too many maximas in the U.S. (afaik), especially when it only had a 3 year run, which spiked my curiosity to the car itself. It reminds me of the Datsun F10 or the Nissan 200sx (84-86), the weird odd ball cars that didn't sell well, but Nissan tried to span its line up of cars for the U.S. market.
  5. I was 12 years old in 09. My first Canby was 2015. Feel old yet?
  6. And how did I not know this?? I've got to swing by to get some pointers 🤔 Also I loved your maxy man, when I saw it at datslocos years ago, it's what turned my attention the maxima. Definitely an inspiration!
  7. Probably not actually. The stock 300zx Turbo is a T28 IIRC, and the diesel is a 2.8 vs a 3.0. Diesel engines also give out alot more exhaust gasses in nature, so it may spool very quickly! I won't know for certain until I try it out, but that's the fun of it. There aren't too many guys who have Turbo'd their ld28s. There's a couple of guys in Germany who have done this, and a handful in the ld28 Facebook group.
  8. Did someone say BOOST? Took a little bit of carbide bit and sanding work to get it to fit onto a LD28. Bought all of these from a guy only a few hours from me. Came with a NOS 280zx Turbo Oil feed line and a Oil pressure Sensor and Tee fitting. Came with a low mileage 300zx Turbo. J pipe plan, using the stock 280zx Turbo J pipe. Not ideal, will change in the future, possibly when I go fmic. No current plans as of yet.
  9. Some fun updates. Put about 9k miles so far, been a nice, efficient daily. Had to work in L.A. for a month and it did the trip twice without a fault. Met one of the maxima guys down there and bought his set of 15" ssr mk1's. Took some parts off the white maxy to fix the hideously crushed fender on the pass side. Not perfect, but better than it was. It wasn't easy to find a passenger marker light. Bought a 83/84 grill and painted it and the headlight surround black. Gonna have to redo it since it's not perfect. Threw on the Tein S13 coilovers with s13 LCA, brakes, and tie rods up front. Install was very simple!
  10. I'm in for sure. I'll bring a different datsun this time around 👍
  11. Still workin hard. 300 mile round trip to pickup the diesel... now this diesel is a special diesel, take a good look at the photos. Youll notice some oddities, like no EGR, mid sump hammerhead pan, Dip stick located in the middle, no thermostat... Making this diesel most likely a boat diesel, either from the states or out 👌
  12. Heres more pics. The beater parts vehicle. Already put work in. Cleaned up a hackjob 5$ walmart parking lot spray job on the roof. Took my time, found some shoddy fiberglass and filler work in the drip rails and window corners. Rust is springing up due to bad prep, so thats urgent work.
  13. Bought a new one, 1982 Diesel maxima, 5 speed 😏. 216k miles on the clock, and still gets 28 mpg combined, and Im not light footed. Dont fret, my 620 is still with me, but this shall be my sweet, comfortable daily. Until I ruin it! Plans are to go shakotan with this mofo, nothing crazy, s13 suspension, and on the lookout for 15 inch SSR mk1's 🤤. Also bought another 82, diesel automatic for parts. It was a too good of a deal, because it came with a diesel, and a spare diesel! So that makes 3 total diesels in my hands 😈😈. Also picked up a set of Recaro lxb's(?) for a really good price. Think theyll look good with some work 👍👍

    620 Grille

    Where are you located? I've got one located in sacramento CA.
  15. Been a bit since I've updated. Some of the prep was for powerland. Put in a 510 aluminum radiator. Picked up a pair of 720 4x4 springs from pick n pull. Made my own air stacks, using a backing plate of a 411 sss filter, and used a press and trailer hitch ball to create a cone. Not perfect, probably not practical, but it works. Due to being lowered four inches, I went ahead and made a carrier bearing spacer, and replaced the carrier bearing rubber with a 1 inch sheet of rubber. Might be temp, might be permanent.

    73 620

    Man that bumper looks like its straight out of mad max. Nice project man
  17. This is an awesome start to a thread! I also live in Sacramento, close to elk grove, and I daily drive my 620 everyday, and use it for work! I've been daily driving for almost 2 1/2 years, and put about 25000 miles on it. I've also done two trips up to Canby Oregon with no issues. If you ever see a orange long bed in sac, its probably me. If you're relatively close to the rancho area, I would recommend looking up Sacramento Datsun Owners club on facebook, and this friday we'll have a meeting at Round table pizza at 2234 Sunrise Blvd. We've got plenty of people who'll have parts and plenty of knowledge! Just as a fyi, I am still running 4 way drums on my truck, and they work okay, if you have them adjusted right. Going to discs in the front are definetly worth it if you have the time and money, but drums are more than doable. In fact, I changed out all of my brake cylinders and brake master, and drove with 30+ year old brake shoes.. I was short on money, so I rocked them for a short period of time, I wouldn't recommend it though. If you ever need help, just message me on here, I have a surprising amount of free time so I don't mind a little drive to help out!
  18. Hey thanks! I'm 5'8 or a 172 cm, so I sit rather comfortably in my truck. My bench is pushed up pretty far, but I think my 'new' bench is broken, as the tilt of the back support doesn't hold a spot, it just leans all the way back. I'll need to fix it when I pull it to fix the seams and cushioning. The Z seats I had made it nice to drive when I pushed it hard around corners in the mountains, but its not very comfortable for long trip drives. The bench is definetly the way to go. If you have trouble finding benches, there should be a couple of threads about people talking about bench swaps, like bronco rear seats and d21 seats, etc etc. From the pictures I've seen, you have a very clean truck there!
  19. Well updates! Been a while since I picked up a new project, not a datto, but a 1988 Mazda Rx7 Turbo II. Here's a pic for whoever cares, sitting since 2003, got alot of work to do. When we pulled it out of the owner's garage. My 620 started to spring a head gasket leak in the #1 cylinder, causing it to burn coolant, and pressurize the coolant system on the engine side. So off the head went. Oh and did I say this was happening over christmas? It was fun, the motor is definitely a low mileage motor, with no ring ridge, and all cross hatches showing. #1 cylinder plug Pulled the valves and put in new valve seals and did a quick valve job. I believe this head hasn't been shaved from the looks of it. And it wasn't warped and within spec according to the book, so I just cleaned it up and threw it back together.
  20. My l20 has SU's and I daily it just fine. As long as you do your normal maintenance (damper oil, lubricating the linkage, occasional tuning), its a great setup. My setup runs too ruch since I have the incorrect floats to float bowl covers, but i still get 19mpg in the city and 28 highway.
  21. Those dually fenders are exciting! I've always wanted to see a dually short bed. Keep up the awesome work!
  22. Hey guys, last night my original fuse block died. The plastic retaining the head lamp clamp melted right through. It was just due time I presume. So I threw the eBay fuse block on to get it home and I got home no problem, but I noticed that with key off, accessories that are supposed to be hot on ign is hot constantly. (Radio and tachometer) and drained my battery. Who can tell me why this fuse block is wired like this, and if I can just splice it to copy the original fuse block?
