Definitely couldn't hurt, let me know when you do that how it goes.

With that said, I still have new tie rods, and some various front end bushings coming to tighten things up even more.

Good news, the straight line shimmy is 100% gone as of today. Went to a buddies and we ran fishing line on jackstands to check toe on all 4 wheels with steering wheel centered (working out degrees later tonight because im curious). Front Left was 4mm toe in Front Right was 9mm toe OUT Both rears were 1mm toe in My Car would track right pretty heavy, and the 9mm toe out explains it all. As soon as I adjusted the front right Tie Rod, we got it dead on 4mm toe in and the shimmy disappeared completely. Can cruise in 5th 2000rpm with a rock solid steering wheel, that use to be the worst spot for vibration.

That's frustrating since i've seen that theme in some searches I did, one guy went to 3 places, at the third shop the vibration finally went away when they balanced it correctly. I just had them balanced two days ago, but i'm tempted to do like you did and get a second opinion. Thanks for the feedback. Good choice in wheels btw . I've heard positive and negative things about a wheels on the car balance, but in most cases it completely solved peoples issues. Seems like an all too common issues on Z's and very aggravating like you said. With my old tires, I was at the point of not enjoying the drive anymore. I replaced my front wheel bearings a few weeks ago, but it didn't have any effect on the vibration. An alignment would be smart for me as well, I think i'll take both your feedback, go to another shop tell them my situation and get re-balanced and aligned.

Also been trying to solve a steering wheel shimmy (vibration) at about 55-60mph not related to engine rpm. I thought these wheels/tires would fix it, which they did help a lot but it's still there just a lot less pronounced. I've done a lot of searching, but the results are pretty much ANYTHING in the front suspension/steering as potential causes other than wheels/tires. So i'm gonna start with the TC bushings since mine are pretty cracked, then tie rods, and test/report back after each, unless anyone else has some advice on that, it would be much appreciated.

Thanks for the tank pics guys, that's definitely a mod I want to do at some point, maybe if/when the external pump acts up. On another note I joined the RB club, I know the wantabe style is used a lot but it's always been my favorite so it was a easy choice. Wheels = Rota RB, 16x7 +4 in Hyper Black (looks like a dark chrome in most light). Tires = Dunlop Direzza DZ102, 215x50r16 (compromised between 225's and 205's) So far zero rubbing anywhere on one hard drive. I really want to lower it about 1" somehow.

If you can, get a ID size of the tank outlet port. The 7/16" hose is a tight fit so it may be 3/8" ID already. So far so good though, I haven't noticed it being a problem when I mash it on my stock LS setup, no big power mods (LS6 intake/injectors is about it). The limiting factor in my setup is the 6AN stainless braided PTFE, the ID of that measures out closer to 5/16", so with actual 3/8" ID line you'll be well off. The Baldwin pre-filter I got is extremely high flow, I wanted something to catch potential debris before the pump but I hear what you're saying with the more constrictive filters. The pump seems happy and quiet being mounted so low it chugs along well.

Shotty vid, but you can at least hear how it sounds and see a little rip. It's tempting to slide every corner, everywhere. ZLS.mp4

You did an amazing job from the looks of it, what a clean Z. I'm glad I could help, just passing on the information I learned here on HybridZ. That custom center console is really nice, did you have that done before the swap and adjust the shift boot, or just do it now? I like where you mounted the fuse block under the dash, that helps keep the inner fender clean on the passenger side. If I redo the wiring i'm gonna move the ECM and Fuse block inside to really clean up the engine bay and make maintenance that much easier. Love the subtle stripes in that paintjob too.

Hey Whitley, Only mechanical updates/issues were a wobbly Harmonic Balancer after I drove for awhile (may have always been there but I spotted it recently). It's a higher mileage motor and i've been pushing it hard so that's understandable, got a new pulley and ARP bolt coming to hopefully take care of that. The car itself with this drivetrain is so much fun, it has the perfect power band for around town and country roads, and with the T56 3.54 diff it cruises so easily at 80-85mph on the highway. Next update will be a brake job and some new wheels/tires. Planning to go with 15x8 0 offset Enkeis with 225/50 tires. From what i've gathered they fit no flare Z's well without much issue and will be a big improvement over the current pizza cutters I have. My only handling complaint at the moment is with the tall skinny tires, I can feel them flex during heavy cornering but the upgraded 225/50r15's should help a lot. Overall, i've daily driven it to work on every dry day and had a blast. It's basically a streetbike on 4 wheels with how fast you can scoot around people.

Sorry to hear you have fitment issues. Those appear to be the 2.75" tubes? I had to send mine back to be modified like the pic below. I'm surprised they sent out the original design knowing it had no chance to clear the #1 spark plug, or #7 plug like in your pics. Passenger side was never an issue, but Drivers side needed the jog on #1 primary (pic below), and #7 needed a dent or jog (I dented mine) because I wasn't going to send them back again.

Thanks Richard. The exhaust was one of my favorites parts to do, i've never done a full one myself before so it was a nice test. Your Z is awesome, that looks really good and extremely clean, especially the 240z bumpers and air dam, love that look. Hope your LS swap goes off without a hitch, you're gonna love it. Where did you find your bumpers listed to get them from Vietnam?

About time to ditch the crash bumpers now that it drives again. Interior somewhat sorted too. Spectre 6284 shift boot worked after modifying it but wouldn't recommend due to the custom nature of it. Working on a leather outer boot now. The shift ball is a trailer hitch modified (shift balls are pricey :X) one day i'll get a real one :D.

Got the last bit done tonight, tucked as close to the diff as possible. Just need a couple hangers here and there and full weld it. *Got it fully welded and driving. The combo of Dynomax Bullet and Borla Pro XS are an amazing combo. Smooth deep and mellow at idle, comes alive with rpms but still smooth and deep with no rasp to note, very happy with those products. I was able to do the entire exhaust with just the mandrel bends listed above, didn't require any straight tubing.

Got some time after work to start the exhaust. Tacked everything back to the bullet so far. Didn't end up needing the 2.5" straight piece, the mandrels above had enough straight sections. Tomorrow hopefully get the 3" section and muffler in place.
