  1. Rob at Z Car Garage is great but don't expect it to be cheap.

    How to search?

    Go to google and type in: 280Z turbo swap site:hybridz.org
  3. When I was first looking for a cheap (<$1000) project car circa 2006 it had to have RWD, a manual gearbox, and fastback styling. My first target was the Porsche 944. Thankfully, I struck out on a few of those and expanded my search to A70 Supras and S30 Z-cars. Ended up getting a 240Z and didn't look back. Similarly to Jon, I ended up with a Z because it fit my criteria and was dirt cheap at the time. If I were searching now under similar budgetary and performance constraints, I bet I'd end up with some sort of E36. That said, the Z has been a great platform to learn on and play around with. The added bonus is that it has a timelessness that the 944 and A70 Supra could only dream of.
  4. The 260Z VIN is an "RLS" prefix. "HLS" is 240Z or 280Z.
  5. Paid $1637 for the wheels + tires originally. The tires are very grippy (200tw extreme performance category) and have lots of life left. I can do $1200.
  6. I have a set of almost-new 16X7 ET0 Panasports with 225/50-16 Bridgestone RE11-A rubber. I bought Wats and would be willing to sell these. I'm local, if you want to have a look sometime.
  7. What do the other cylinders read on the flow meter? If the others read 5, then you possibly have a vacuum leak, bent throttle rod, or misaligned butterfly. If the others read 4, then you likely have either a bent throttle rod or misaligned butterfly. Remove your progression hole covers to diagnose a bent throttle rod. Use smoke or spray for vacuum leaks. If everything comes up inconclusive, then a butterfly is misaligned. This assumes proper valve lash and even cylinder compression.
  8. The ball-and-socket kit won't bind or snap TC rods but it will be harsher than rubber.
  9. Ride comfort is a systemic attribute, it's not just springs or bushings or... Spring rates set ride frequency which sets the amount of force, thus acceleration (F=ma), your body will see from road inputs. These accelerations are tuned via dampers and isolators. This is mostly reflected in how "stiff" the car feels when hitting bumps and dips in the road. Then there's the matter of impact harshness from road imperfections. This is more of a noise and resonance issue. This is dealt with via something called compliance. The bushings responsible for controlling the amount of longitudinal compliance were already mentioned in the post you found. This is all assuming you're not running out of travel on your suspension. Fixing harshness is going to involve making sure you have soft compliance bushings and top mounts. If you're running coilovers with a solid top mount (ball joint), that's not helping.

    Bummer! There's always next year. Seems they're finally giving some credence to Japanese car makers. I'll be curious in what you come up with.
  11. I finally have a few minutes to sit down and start a log for the "new" 260Z. It all started with JCCS last September... I took a trip from the Bay Area to Long Beach in the orange 260Z in September. My fiancee came along and we made a vacation out of it, staying in San Luis Obispo for the weekend and driving to Long Beach and back on Saturday for JCCS. I tried to contact one of my favorite professors from college in order to meet up with him while we were in town, but unfortunately he got the email too late. He was my Ground Vehicle Dynamics professor as well as the adviser for our FSAE engine development senior project. During the early stages of the project, while discussed ideas with my teammates and browsing an old ICE textbook, a picture of SU carbs popped up and I exclaimed, "hey, those are the same carbs as my Z!" At the time, I still had my (first) blue 240Z and the red shell. My professor overheard this and it all began. As an aside, he's worked for Dan Gurney's All-American Racers and the Benetton-Renault F1 team, pretty damn awesome! Back to the present... In one of his emails, he mentioned that he was thinking of getting rid of his Z in order to make space for a new race car - an F2000 open-wheeler. Of course, my interest was piqued! He was the second owner and had owned the Z for 24 years, and it had gone through many moves, across the country, and even to the UK and back with him when he went to work for Benetton-Renault. It had also gone through a few colors: originally gold, "baby sh*t brown or depending on who you talk to 'caramel'", BMW BRG, and finally Jaguar BRG. He had the paint done at a high-end hot rod shop, a 2 stage base/clear job. While the paint was being done, so was the body repair, welding in new metal in the fender and rocker, and rust-proofing everything. It has an essentially brand-new interior, including a new Nissan dash (!), new weatherstripping, new brake and fuel hard-lines, new wheel bearings, rebuilt braking system, new or re-chromed bumpers, coilovers, fat front and rear ARBs, and on-and-on. Of course, it came with some extras including: ITS L24 with Rebello-prepped E31, Tilton flywheel, coated MSA 6-1 header with mandrel-bent exhaust, 260Z Euro tail lights, a copy of the '73 FSM, binders filled with records, etc. Clearly, it was tough for him to make the decision to sell it, but it's nice to keep it "in the family" so to say. Needless to say, I'm quite happy to have this Z! Before leaving SLO, we had to hit the Pismo Dunes so we rented a pair of ATVs. I haven't had fun like that in a while! I had to make sure to represent (yes, I am wearing a pink helmet ): I rented a U-haul auto transport and borrowed my future in-laws' 4Runner to be the tow vehicle. Our fears were confirmed however, as by loading the Z ass-end first too much weight was placed on the trailer tongue. We unloaded the car and repositioned the trailer. The Z rolled out of the garage and into the street, probably the first time it has seen sun in years, if not close to a decade. The most important job of all went to Melissa. We were all just hoping we wouldn't pull one of these: www.youtube.com/watch?v=CH3i1Y0yXIg In the end, we prevailed! Getting some lunch at one of our favorite spots in SLO, Jaffa Cafe, before heading back home... Oooh, nice engine bay! Damnit, who's the a-hole tailgating me! And she followed me all the way home. Can we keep her mom, please can we? And a nice sunset over South San Jose It was a successful trip and now she lies, waiting in the garage. More to come!

    I haven't had the time to swap in the new bits due to family commitments and race car stuff. I did drive the Z down to Laguna Seca for the Historics yesterday and man is this car terrible to drive! The lack of suspension travel makes for an abysmal experience and the rev-hang in between shifts is really aggravating. I won't drive the car again until I can swap the suspension. The rev-hang needs further investigation but the symptoms point more to a vacuum leak than a linkage issue. I'll do a quick linkage check and then put some smoke through the trumpets to see if we're leaking air anywhere. Reinstalling a speaker so I can finally use the radio, in combination with the above, will go a long way to really refining the car.

    Triple carb intake length

    The length has nothing to do with it, it's all due to the balance tube and misaligned holes for the throttle rod bearings. Pierce Manifolds is a vendor, they do not make their own manifolds. I'm guessing you're looking at the TWM manifold that they sell. I run one on my Z, it's definitely better in quality than the Cannon but it took some hogging out to make the ports match, FWIW.
  14. I'll be there Sunday with some friends, managed to get a spot in the ZONC car corral at Turn 3. I haven't been to the Historics for about 6 years or so, should be fun!
  15. Sounds like you guys have damping/travel issues.

    Great! I appreciate that man, send them over. Would love to have a look.

    You don't wanna know! It's some fancy-pants scanner, I can't remember what it is at the moment...

    Leon's Other 260Z

    Scan data is complete. He went pretty in-depth with modeling it up. Andrew, I sent you an email. Let me know if you don't get it.

    Gollum's DD L28ET 75'

    Congrats man, great to see this thing finally running!

    Leon's Other 260Z

    Right on, I'll let you know when I get the file! I'm definitely spoiled with the equipment and people I have access to at work. Things would certainly go a lot slower if I didn't have these resources.

    2.5" vs. 3" comparison

    I'll do it on my L28 if you would like to pay for a 3" exhaust for my Z.
  22. Leon

    Leon's Other 260Z

    Right on man, thanks! The scan data is currently being converted into a solid model (it's raw form is STL) so hopefully I'll have something today. Do you have a preferred file format?

    re-mapping and live tuning L28ET 1982/83 S130 ECCS

    Good to know! I don't have any EFI Z-cars but it's cool to see somebody playing with it at this level. I'm in the SF Bay Area as well (Burlingame), I'd love to check out what you're doing sometime.
