  1. Clearance issues aside this is looking pretty sweet. You're one of the first I've seen running the newer G series turbo on an L engine, much less one with carbs.
  2. You're gonna be out by an entire inch from where you are now. More aggressive negative offset on top of the extra width is going to require flares or some pulling and rolling. The front fenders have a bit more clearance, but the rear will definitely be rubbing and the top of the wheel will be outside the body line unless you get some fairly aggressive negative camber. I'm with jhm that's it's partially the style of the wheels that will determine the look of the dish You're near the limit of what you can do on a stock body with reasonably wide tires and camber.
  3. Based on the mark on the exhaust manifold I think it's coming from the NPT to AN adapter on top of the extension. Looks like it's sort of "spraying" so really only leaking when it's really hot on the long drive. Doesn't seem to drip or anything otherwise, just need to tighten it a bit more when I'm back home. I've just used basic white thread sealant on NPT threads or the BSPT threads and haven't had issues honestly. (Using the fluid one, not the tape stuff)
  4. Most of the interior is well coated, the cup holder and something like the shifter are the few "open" areas that can't be be totally sealed off or are going to get hot over time anyway. The entire interior is coated in lizard skin and everything but the roof has dynamat. No issues with anything carpeted as far as heat goes. I think at this point the issue is preventing as much heat as possible from getting to the metal to begin with by treating the underside with more lizard skin ceramic or some kind of transmission tunnel cover. In town and really in a drive less than an hour or two you'd never notice it
  5. Heading back to Mexico. Had a nice final cruise and coffee run in my hometown. The drive back was SMOOTH after a Datsun friend in Washington got my alignment back where it belongs. Massive difference with the bump steer spacers under the brand new steering rack and having raised the inboard mounting points of the front control arms with the new crossmember The beauty of longer drives like this is I get to REALLY test it and, especially in the heat, notice things that would otherwise never pop up. -Pinion seal on the diff needs to be replaced have a nice spot on my otherwise clean stainless exhaust from the fluid. -One of coolant fittings in the back of the head isn't quiiiite sealed. Looks like it splattered a bit on the the Cyl 6 runner for the exhaust manifold and probably at least partially responsible for the streaks I saw on the transmission bell housing. -Something's up with the oil pump or area immediately around it. Seems like once the oil is warmed up it's leaking slightly and the fan is spreading things around. Gasket looked good around most of it though, saw drips of oil on the bolt heads mostly. -One of the injectors is possibly not perfectly seated. It took a LOT of miles but there's almost a fine dusting on the last couple and on my fuel hose and pressure gauge. -The seal around the oil fill cap is cracked. I'll debate whether I just get a new seal or a really nice cap around birthday time haha -The plastic ring/sleeve on the backside of my horn has been cracked for a long while. Typically holds fine, but I'm stiffer bumps it falls right between my legs haha. I remember seeing some kind of 3D print replacement somewhere. I'll look into that more or figure out an original replacement. -The screws that hold up the fresh air vent thingamabob switch thing are M5x... .5. no one carries them locally but it's finally time to bolt this thing up and not have it just dangling around under the dash by the passenger foot well. - Finally - looks like I need to do even more about heat, especially off the transmission tunnel. My cup holder from Milkfab was getting nice and hot and turning my drinks into tea by the end. The cabin stays nice and cool despite no AC for now. The lizard skin SERIOUSLY helps, but I think I need to coat the underside so less heat gets into the metal to begin with. -Another consideration is using my vented hood. It's been sitting outside my dad's shed for a while, but I'm debating getting it sand blasted then paint matched and swapping to it. The other option is a carbon hood. Either way, I need to get heat out of the engine bay. All Things considered, pretty small things for a nearly 50 year old car built by a music teacher who does this as a hobby with this as my only experience building a car
  6. Almost ready for the drive back to Utah tomorrow. Car has been running quite well since swapping the ignition coil. I'm currently in "square" GM truck coils, and next year plan on fully swapping all of them out for reliability so I'm not having the issues I had this summer. Christmas visit I think will finally be time to run the AC lines. Over 1000 miles on it just since Thursday, and probably another 1000 between short rides here and the drive back to Utah before I head off to Mexico again. Got to do some nice rides out here on the islands as well as up to Vancouver. Despite the repeated frustrations, and various rattles and small noises I'm not expecting becoming extra obvious with so many miles in it, it really is a joy to drive and I'm happy with how insanely different this thing is from even a few years ago. I was telling my brother in law that it's weird looking back at old folders of pictures I had of other cars for motivation because my car is better than most of them in most ways now haha
  7. Made it to Washington! Bit of oil is leaking from the oil pump or the front of the oil pan. Not severe enough to do an emergency fix while I'm around for a friend's wedding a few days but probably something I'll address when I'm home for Christmas. Ignition coil on 6 went out with a couple hours left in the drive. Was going crazy thinking it was a connector again, but ended up replacing the coil this morning. Unplugged the injector and turned off EGO correction so the rest of the cylinders would at least be close for the last bit of the drive and took it easy but I think these old LS2 coils are just going out. I'll need to upgrade all of them, I think they were already old and pulled off a junkyard engine by the PO. Only other hiccup was more vibration than I'd like but I don't think it's the alignment. Getting tires rotated and balanced right now. Haven't done that since I first bought them which at this point has been several years and close to 10k miles between the now 3 round trips from Seattle area to northern Utah and the cruise down the Pacific coast highway. First time around I had them done at Discount and I feel like the guys there didn't do a couple of them right anyway Mostly small things but with how many miles I like to cruise around they get very noticeable
  8. I assembled them with plenty of grease (which actually made inspection a bit messy haha) I did manage to tighten them properly with the help of my brother in law's impact and the seem well seated now and aren't just loosely spinning around. I really think they just didn't seat as well as they should have when I first installed and it gave a false sense of security when I first torqued them down. If the few miles I put on them last summer before moving wore down too much and they tell me I need new ones I'll definitely reach out. Ball joints are easy, I'm mostly hoping the bearings don't have to be replaced, since those have maybe 6-7000 miles. Took so long between installing and really using the car that I never bothered to double check the torque after a few drives.
  9. Wasn't charged for alignment. They said my wheel bearings and ball joints were loose. They got the toe close and it's driving well but I'm noticing the playin the center. Probably wasn't noticeable before with all the play in the steering rack. I've tightened the wheel bearings and noticed the improvement immediately, next up is ball joints. I think brand new nicely greased parts from Apex going into nearly 50 year old components just didn't seat completely on install. Inspected the ball joint yesterday and it seemed completely fine, just loose. Need to find my 1/2" impact attachment, was only able to tighten a bit yesterday since it was just spinning.
  10. So cool to see you back around! Definitely took a lot of inspiration from your threads back in the day, though I've gone full turbo since
  11. Oh I forgot the most important detail... My annoying noise seems to be solved. I did replace the driver side CV, but there's a chance the new stiffer Kameari mounts stopped some movement and it was slight exhaust issues all along... Should have tested separately but I have things to do haha.
  12. Fairly positive it's never been in an accident, but it's so hard to know on a car nearly 50 years old. Gonna ask T3 if anyone else has had the issue. There is always the chance that the mustache bar studs are slightly off on the body. Got the car back on the ground yesterday. Shaved the fins enough to mount the dog bone but I need to get longer bolts to mount the rear sway bar. The ones included from T3 are a size thicker. I think their design has changed just slightly since I purchased mine, I have a hard time believing they've included the wrong size bolts twice now, once when I bought the new sway bar, and once when I got the fancy caps. I got the alignment shockingly close just by measuring both sides to the end of the tie rod end. We'll see if I'm actually close or just imagining things when I get an alignment tomorrow. The front camber is slightly more negative now since I moved the inboard mounts on the front control arms up a spot from what I think is stock on the new crossmember. Between that and the bump steer shims in the new steering rack I think it should be driving waaaaay better. Three or four days left until I drive it up to Washington for a friend's wedding and really see how it's going on a longer trip
  13. Zero issues. I finally got better screws for the connector case and tightened it up properly. Started running rough halfway through my first longer drive. I guess the vibrations shifted it out juuuust enough that some of the pins didn't make full contact, which makes sense in retrospect because at cruise it was sort of subtly surging, which I know know was one of the coils not firing every time. Agree on the T3 fitment issue. The problem isn't just that it's thicker though, it's the shape of the top. It doesn't dip down at the sides almost immediately like the stock bar, so at the top it has less clearance. I probably could have kept the studs honestly, but with the fitment and lack of flexibility I couldn't even slide the thing on to check without removing the whole diff and just assumed that I'd be needing the spacer and the studs wouldn't be long enough. Would not say I'm unhappy with the angle of my CVs, but it's also so hard to see it properly while on my back. I can tell they're very slightly angled back to meet the diff, but it's less than the angle they're at vertically just while sitting. It's not a huge deal, they'd be a pretty horrible part if they couldn't handle tiny variations outside of perpendicular As far as your fitment, do you have an older version of the bar? I think they've changed slightly over time. I can live with skimming on the mount. I'm more bummed that I have to slightly shave the fins on the diff cover to clear the mustache bar. The diff cover was near perfect condition original piece (minus some grime), but I don't plan on selling so the value isn't tooooo big of an issue haha
  14. We got the diff cover studs out, but I feel like I'm not totally happy with the fitment of this t3 bar Seems to be just skimming the fuel tank mounting point on the spare tire well even after a bit of thumping and hammering. We'll see how it holds up. Also only used some washers instead of the spacer provided by T3. I think I still have some adjustment on the RT diff mount and the spacer might get the CVs completely perpendicular to the wheels but it's close for now. Other major project is the new crossmember/steering rack/Kameari engine isolators. I couldn't use the adjustable engine mounts I bought for now because the top runs into my oil pressure sensor due to the T underneath it for the oil feed to the turbo Aanyway, mostly done with this major project. Just waiting on a new tie rod end since both the ends on the new rack are right hand thread unlike the original Last little problem I had was a cylinder not firing. Racked my brain over it for hours only to find out the DB37 connector on my MS box wasn't completely seating... The side of the connector that was just slightly lifting enough to have intermittent contact issues happened to be the side with the wires for spark control
  15. This is looking so sick! Especially impressed with that harness.
  16. I'll take some pics of how it works during the week. Car is parked at the show I was prepping it for. Even if they stuck with studs I'd have to replace them with longer ones. The billet is thicker than the steel mustache bar. It's also completely straight and has a billet spacer to account for the curve in original bar to meet the mounting face if the diff cover. Original studs barely get you 3/4 of the way through the material on the new one. Haven't worked on it a ton, but aside from being more pieces and more hardware to potentially back out, I think their mustache bar would actually make it easier to service everything
  17. Summer Update before the show and parade: -Fuel filter replaced -Intake piping between IC and throttle remade and working now -Ended up have to purchase a new battery ($$$ ☹️) -Cleaned out inside of car -Vacuum lines for ECU and BOV redone -Car is now back to driving! Notable problems/hangups: -Did not have time to install the new crossmember and engine mounts. Will save for next week. -I was mostly ready to install the new T3 mustache bar then realized it uses bolts instead of the studs on the diff cover. Spent several hours trying to remove the studs with no success and ended up putting the OEM one back on. I'm so sick of this type of work and hang ups that I'm ready to just drop it off at a shop and have them pull the studs for me -Car can't seem to idle below 1100-1200 once warm. Can't tell if I'm missing a vacuum leak somewhere, but idle timing correction IS kicking in and PWM on the IAC is near zero. I'll check it when I'm not rushed to show it off this weekend -After driving again after such a long break I'm now pretty certain what I thought was an exhaust rattle is actually unfortunate timing and one of my CVs has gone bad. I think I just had a luck of the draw in a part that didn't last. When I was checking the sound I noticed it only happens under load and the speed of the tapping depends on the car's speed - not on RPM. Exhaust tapping would get faster with engine RPM, I tested multiple gears at the same speed and it made no difference. Rock Auto replacements of what I have are cheap so bought another couple. Hopefully problem is solved because that's the only thing that makes this car unenjoyable to drive right now. Most other things feel pretty good!
  18. Oh I'll absolutely take a ton! Flight is scheduled for the 26th this month. 27th and 28th of June will basically be full car work all day with some food breaks haha. I want it to be ready for the Cache Valley Cruise-In. I've considered that, but opted against it. If the mounts don't work I'm just going to cut and splice in about a 1/4" section to the middle of the downpipe. The midpipe also has to be remade to add clearance to the resonator anyway. Had incredibly good exhaust clearance until i opted to add more to quiet the sound - my frame rails were the lowest part of the car. I think I have enough room for an upturn in the midpipe that raises the already dented Vibrant unit.
  19. More recent purchases for the summer work: -T3 mustache bar: I ran the original for a long time, but it actually rubs against the dogbone for the drop mounts which concerns me -Kameari Engine Mounts: after consulting a lot of people and posts I decided against poly mounts since this is a full street car. RHDJapan with shipping was about the cost of buying OEM rubber units so I went for it. I'll report back on quality/comfort. -Adjustable engine mounts: for whatever reason my engine always sat high when first installed. I had to go without the front/rear isolators or my valve cover would rub the strut bar (it already put a notch in it). Lowering it slightly will fix that, PLUS hopefully fix my downpipe issue. When I added a spacer on the new turbo, the added angle on the downpipe to clear the floors made it just high enough to rattle against the trans crossmember. Hopefully I get a two-for-one on this part and don't have to redo the downpipe.
  20. If you're gonna get aftermarket that fit poorly and require a bit of work, just get the ones from Z Car Depot. At least they're $37 ea and you're not out so much and they're probably from exactly the same place originally. I believe I got mine from JDM Car Parts. Paid $140+ and they fit well, but I can't tell if they were OEM at the time. I thought they were only available OEM when I purchased mine. https://jdm-car-parts.com/products/rear-hatch-hinge-seal-set-240z-260z-280z-69-75?variant=766736517 Still need the plates, they definitely seem more important than you'd think.
  21. The front end of these cars is already so questionable in terms of aero, that I'd be weary of doing anything that let even more air go places you don't want it. The hood in particular is already prone to lift due to the air flow. Sealing that top with the appropriate rubber strip can help mitigate some of the issue and make sure you're getting airflow to the intercooler and radiator where you want it. If your car is not done and you haven't driven it at highway speeds it's hard to grasp just how noticeable the front end lift is. Steering starts to feel very light above 75-80mph. Scarily light even. Enough that I was scared an avoidance maneuver on the highway would quickly make the car lose control and put in me in a ditch when I was trying to keep up with traffic through Idaho a couple years back. The difference in confidence I had when I finished my seals on the front and added a splitter was night and day. I'm not sure that upper area does anywhere near as much as the splitter, but I still don't want more air pressing up against the hood. Realistically, how much are you losing by bolting the intercooler to the bottom instead of the top of you cut it? 1/4"? Maybe 1/2" in some extreme situation where you add washers on top of the plate to avoid rubbing against the paint or something? If it creates tiny clearance issues with your intercooler piping just bend the plate out a tiny bit so it doesn't drop as much.
  22. Tiny updates and partially just a list for me to do over summer while I'm thinking of it: Recent purchases: -Floor mats (finally). We'll see if these even work, Between my sound deadening and carpet, I think the gas pedal might start rubbing against the carpet. -Engine lift hooks (mine were cracked). Important for lifting and replacing the crossmember and steering rack this summer -OEM brake booster check valve. Summer work in order of priority for this summer: -Replace glass fuel filter -Replace crossmember along with steering rack and re-align -Purchase correct size coupler for new throttle -Chamfer IAC inlet on throttle with a dremel (some serious whistling sounds happening, really obnoxious) -Redo intake side of intercooler piping -Tighten coolant lines and refill coolant. -Make power subharness from relay board on passenger side out to driver side where the ECU is under the seat -Install catch can (even if hose routing isn't super tidy) Lower priority -Redo center section of exhaust to improve clearance (would be high priority if I was driving more, but moving to mexico changed things haha. -Replace exhaust hangers with more rigid pieces to remove rattle. -Finally bother to build the AC hoses and charge AC system. -
  23. You always seem a few steps ahead of me and with better attention to detail haha. That RMS is a job I'm hoping to do this summer. I have a leak in the same area. Same with the Z Car Garage brakes.
  24. Are you still running the original ammeter? There's a reason they switched to volt meters with the 280z, lots of current going through the dash harness.
  25. Where did you get the flywheel tool? And any chance you can share the file for that seal tool? I've had a notorious leak that I'm almost positive is the rear main seal so I may be doing this next time I'm home. My brother wants the leak fixed so he doesn't have to have cardboard under the car when it gets stored at his new house haha. Debating going with a lightweight flywheel while I'm there, but since I'm making less money now (though saving as much with fewer expenses) I'm avoiding too many "mid cost" sort of items so I can save for a major brake upgrade down the road.
