    Fancy Rear Bumper

    I've seen someone use them as anchor points for I think a ski rack that goes along the rear hatch. Not a big fan of them either, the clean rear bumper is just right especially since it matches the front, the over riders just make the rear look busier then it needs be in my own opinion as well.
  2. Congrats! If you do plan on cutting the springs I'd just make sure to grab a set of metal CV ties to secure the springs so they don't fall off the perch or miss the hat on the top or run some limiters to keep the suspension from drooping all the way when you jack it up. I ran cut linear 280z tokico springs for a while in my 240z, but it consisted of lowering the car, stopping part way and slipping my hands between the wheel and the arch to align the spring then lowering it the rest of the way. Good way to loose a hand if it unsettles suddenly.
  3. The cosmos run a pretty stiff spring, the suspension felt crashy for lack of a better word. @Boog has/had them on his car so he may chime in. The car I was in was lowered a fair amount though so a lack of travel could be the culprit. You can install the cosmo's "correctly," in that you remove the spring perch and you can weld a perch for them to sit on, they come with some allen set screws as an install option, but I really would not want to trust a few grub screws to hold up the springs. The GC spring perches are additionally a good choice, you can choose the spring to match. You can only adjust spring height though so you will be winding preload into the suspension to raise the rear. Not really a problem, you just will be "using up" some of the spring tension to get the height. It will also unload without the use of a helper spring when you jack the car depending on the install point. Depending on the spring both of these options would require a replacement shock. The GC if you chose to, you could shorten the shock body, run a shorter stock and have a good amount of travel at a variety of ride height. If you decided you will never go lower than stock, then you could run a stock shock and not modify the shock body, although with the modification you could dial in the ride height without worrying about shock travel (I think Z's sit a bit high at stock height). Cosmo would work, is cheap, but not ideal in a few aspects GC would work, and if you shortened the shock body you could lower it with no ramifications BC or other weld on cartridges style coilover will have independent height adjustment so you always maintain a set amount of shock travel, but yes price is expensive.

    New source for CV axle conversions?

    Welcome to the forums! Glad you understand your market, and I'm sure it is a welcome addition. As long as you don't try and sell outside the vendor section, or respond to every post looking for axles with a link to your site this kind of discussion is exactly what I personally like to see. I will have to agree, I have seen some Z's with upward angles, but they would be at chassis scraping status at that point, maybe a point for Z's would be with the tripod joint on the outer end you get away from potential binding with R200's that the axles face which you are addressing with the "short" offering. CV's have a smoothness that is slightly apparent in my limited experience. Not huge, but I can sometimes notice when I get in other Z's with the stock axle, granted as mentioned they could just be worn ujoints compared to brand new CV's. One point I ran into when talking about STI axles when I had an STI diff, is that keep in mind the power was sent to all 4 wheels in these cars, on drift subaru's they definitely have to undergo upgrades as the axles don't seem to hold much power. If this is a stock offering, I imagine it would be from one of two cars and both are of this type of setup, and it seems that you are addressing this with the low stated power numbers. Just as a warning, we as a community tend to be pretty scrutinizing, please do not take offense, maybe view it as an area that could use improvement to put future customers at ease!

    Custom 3D Printed Fender Mirrors

    That is a neat idea. Kudos for making the attempt!
  6. Howdy, noticed you posted in the FAQ section, that area of the forum doesn't allow for replies. I've moved your thread to the correct area. Take a moment to make sure you are posting in the correct section if you would like input from others :D. I'd be a bit worried that with so much weight off the nose and more in the rear the front will feel quite light under acceleration. I would hesitate to cut the springs as the travel on the stock suspension is not that great and you would be loosing more of it. I'd say a basic set of coilovers from a company that does custom spring rates may be worth the investment (BC comes to mind), to get the height and springs right you could just calculate the static load on each corner and calculate the compression if you aren't concerned with dynamic performance or you could call them up to work out a custom solution which would be advisable with the weight moving around so much. You could go with ground control springs and adjustable perches, sectioning the struts would be a good idea to gain more travel, and a new shock wouldn't go amiss, but in the end you would end up about the same if not more than a set of coilovers as above albeit with arguably a better shock and spring. Lastly you could go with an adjustable spring like cosmo sells. No modification and it sits in the stock area. The springs are pretty harsh and the ride isn't pleasant at least with stock shocks, but it is by far the cheaper of the options. I'm sure others may chime in. I will say I cut 280z tokico linear springs when they were on my 240z. It was a bit of a hassle as every time I jacked up and lowered the car I would have to line the spring up or they would pop out of their perch, same thing on off camber hills. The spring perches have holes that you could use with some CV boot steel zip ties to potentially hold the spring in the perch, but it would have to fight the shock, so I'm not sure how long that would last.

    Luxury Daily restomod 280z Questions, Help?!

    I found some features that I think I have been spoiled with. Of course blind spot indicators are nice, but things like TPMS and backup cameras are really handy. I've even bought those for the datsun. TPMS is nice since I don't drive the car much it gives a nice little reminder if one is low and backup cameras are just nice if you are in tight spaces. As long as the car isn't overtly noisy or at least if the noise is limited to either mechanical via engine whine, exhaust, etc I'm fine. I think it is the little squeaks and odd rattle that gets me more.

    Z Car weights

    @Ben280 Had some interesting number when I spoke with him. Something along the line of the doors being much much heavier than I expected. Like 70-80 lbs for the 280z?

    280ZX 2jz transmission help

    Probably not. Nissan bell housing isn't removable. So no bolt in swap type scenario is going to happen. If you had an access to CAD and a CNC machine you could theoretically make an adapter plate, but then you are looking at custom off set fly wheel and such potentially. If you had a TIG that could weld 1 inch aluminum you could in theory graft it together, but then you are looking at trying to piece together the correct clutch scenario which most likely won't happen. R154 are generally made for the 7m, the 1jz variants would work. If you used the R154 bell housing, you would have to either covert the engine to the push type via W58 gear, or covert the nissan trans to a pull type (or vice versa). That would of course be assuming you have perfect distance to the input shaft and the flywheel splines and all that jazz mesh, which they don't. Also not sure what you have, as auto R154's don't exist as far as I know. If you are on a budget you can go with a W58. If you can't afford that, then you can stick with the automatic and convert to a CD009 using that bell housing and a collins adapter conversion thingy in the future. Keep in mind transmission options are expensive for 2jz's. I've done both the R154 and the CD009 and both will put you in the hole about 2k with minimal effort. Best not to limp in on something like this.

    Thanks, I think I am going to try and get some lift time soon and I'll grab a few more photos. It really does look like stock, maybe even better with the speed grooves. The tank is from when they switched over to the LS-1, so 99+ I believe. Notes while I still remember. Most parts you can buy from rock auto, straps, hardware, fuel fill neck, gas cap, lock ring, etc. The Spectra V6 pump says it will push 50gph, but I'm not sure if that is true, I have the pump, but I've never tried it. Their pumps are clipped into a plastic ring and are not readily replaceable other than another spectra pump so be advised. The stock style bucket was found on amazon for about $30, it has the rubber sleeve, jet pump assembly, etc. You can get a stock replacement for something ludicrous like $5-700 from the parts store. Racetronix sells a plug and play kit for the STOCK bucket. It puts a 255lph pump that uses the jet pump and is all wired up, but it is for the STOCK bucket, if you use aftermarket they switched to wider tabs for the fuel pump wires and the plug will not fit. You will have to harvest the new pins from the new bucket and crimp them onto the thicker wires from the racetronix kit. The part that is seemingly non existent is the fuel fill hose that connects the neck to the tank. According to the junkyard they cut those to drain the tank. Given the tank has a roll over valve that seems completely unnecessary, but I believe the stock fill neck is welded to the car so it may be how they remove it easily. I found a hose for an old jeep that is the correct diameter, if you can find 1 inch hose rated for gas as well as some 1 inch hose barbs you will be in business, I could not find any locally. Still looking for the right fittings. Company/part number: Omix-Ada 17740.05 it seems to have sufficient bends and curves to figure something out with some couplers/90 fittings. Note the V6 and the V8 tanks are identical as far as I can tell. The internal bucket mechanism is different. My setup is a combo, I have the top half of the V6 bucket and the lower portion of the V8, the only benefit is that my fuel return goes straight back into the bucket instead of shooting out from the removed regulator port, not sure if it will make a difference. The difference once again is the V6 has a feed and return and dumps into the bucket, no regulator in line. The V8 setup has a regulator built into the bucket and will not return until 70psi or so. I am pretty sure these are the fittings I used to adapt to the top of the tank https://www.amazon.com/Russell-640853-Quick-Disconnect-Female-Fitting/dp/B001P2CKVY/ref=sr_1_15?ie=UTF8&qid=1548038859&sr=8-15&keywords=3%2F8+to+6an+quick I already have 6 an line so plug and play. The pump needs to be primed on your first go around, preferably with adequate fuel. I had it all installed and poured in a few gallons into the tank and the pump wouldn't circulate. Pulled it out and filled the bucket a bit and it gurgled then started pumping. Make sure you prime it the first time before you load it into the tank. The bars to mount the tank against should be about 2 inches wide (note the frame, not the straps). Make sure you use foam on the pressure points, you can see where they used it on the factory tank from the cut outs they have for it (weather strip foam bought at home depot). Ohm range is like 40-250 for the sender. Not many gauges seem to do this range. https://www.ebay.com/itm/Fuel-Gauge-2-52mm-full-ranges-LED-low-fuel-warning-001-F-BB-17/261697663603?hash=item3cee657273:g:PukAAOSwKSRa4yMw:rk:30:pf:0 That is the one I bought and it works well. Pretty nice as mentioned above.

    Thanks for answering all my questions, it is a bit odd not hearing the pump, but at the same time quite nice to have one noise gone.

    Curious, do you pictures from the other side? I wonder how well they smoothed the diversion point for the waste gates.

    Another problem that came up during the autocross was fuel starvation. Part of me thought it was because it was autocross and I was running the fuel cell fairly low. It did seem to get better when I filled up the next day. Then I went on a local drive. A little over half way through the car started bogging and surging pretty badly running pretty lean even at low load. I could hear the pump cavitating. I filled up again and it seemed to go away after I let the car sit, and only returned after 30 minutes. Sent off the fuel pump for warranty in case it was going bad and started assembling a new fuel system. When it returned I threw it back on for a photo shoot only to find the fuel flow from the hose was less then the fuel flow from the fuel cell. I took off the inline filter to find it was about 1/2 blocked. Even after a bit of cleaning it still had fine debris. I think this stemmed from when I drained the fuel into a plastic fuel jug and when I poured it back in the little plastic bits from manufacturing also went into the cell. So the car would run ok until enough of the fuel passed through the filter to bring the debris into clogging the filter. After sitting the debris would basically backwash into the cell. Good thing is the filter did its job, and being reusable is a wash away from being clean. However I had already started down the road of replacing the cell with a tank. Thanks to posts by Joe and a lot of feedback from Omar I decided to go with a camaro tank. That was a whole ordeal in and of it self to acquire and prepare it. We tigged this frame together, only to find it was too long and wouldn't sit on the mounts I had from the fuel cell. So it was modified to allow it to slide in at an angle. A wee bit of undercoat to keep it from instantly rusting. If desired, the tank could be dropped with the straps, and then the subframe could be removed if needed. Much more discrete then the fuel cell that used to be there. The GM sender is also a different ohm range than normal and really difficult to design. I did find a gauge online that worked, but it kind of ruins the current scheme I have going on. Might have to slowly convert everything else around it now, but the gauge has the startup dance, a really nice back lit LED and when you get low on fuel the gauge buzzes and the logo at the bottom turns orange. Not bad for $40 or so.
  14. Tamo, you posted in the FAQ section! I've gone ahead and moved it for you. Are you saying you keep getting bubbles? Bleeding can take quite a while depending on your booster size and how many turns you have in the system. Either the standard pedal method or the pressure bleeder on the master seems to work the best in our cars. I usually go through about a 1/4 of a bottle per caliper if I replaced a line.

    Luxury Daily restomod 280z Questions, Help?!

    I mean it seems like you want to do exactly what the B is for Build guy did. His swap would be considered a donor swap, swapping everything over from a donor. A shell swap or body on chassis swap, which is more of an older term as we are dealing with mostly unibodies, has to do more along the lines of dropping the body/panels on the floor/chassis of a donor. Might be good to look at terms to figure out what you really want. There was a 240sx kit that grafter the front end of a 240z/280z onto it if aesthetics is more or less your goal. Otherwise it is a matter of finding an engine and interior that you like and figuring out how to make it all fit. There isn't really anything about this that is going to be easy or require a minimal amount of fabrication work. Some swaps have been done so they may be easier or kits may be available, but they usually revolve around loosing things such as power steering and a/c. I would look at the how much it cost video he did to have an idea of the cost you will be looking at, if I recall it was almost 50k all said and done.
