    Turbine size matters

    I believe I said this on another thread but your adapter is a very clever design. I have a very similar setup as you including a .62 turbine T3 housing but with a first generation GT35R. I'm thinking I probably have the same issue as you but haven't driven it enough to know. If anybody has a Garrett GT3576R .82 T3/v-band turbine housing, let me know and I will take it off your hands :).

    Your issue sounds similar what big-phil experienced back in 2009 except you aren't hearing the turbo flutter as he was. The solution, as recommended by Tony D was to go with a .82 turbine.

    That's what I figured! But he did turn it around pretty quickly. The cheapo scanner I have at work takes quite a bit of time to turn into a good solid.

    So cool indeed! I'm curious what scanner you used and how much labor was burned creating the solid model.
  5. The goal of this project is to have a stock looking 1972 240z with a much more powerful engine and beefed up drive train and some suspension modifications to match. This car will be mostly a weekend driver with some track days. The only constraint (besides money ) is that I want to stick with the L6 and Datsun/Nissan parts as much as possible. Here is the current list of performance parts to reach this goal.

Here is a video of the car a few weeks after I purchased it. It turned out that the valve train noise was caused by a very poorly machined head. There were indentations on the pistons where the valves were hitting them. Here is what it looks like now. Kinda sad. It's been sitting for a while and is all dusty. The L24 is out. I expect to have the Rebello long block in a couple of weeks (January 2009). Here is my gearbox collection and the L24 block that I pulled out of this car. The clean gearbox is the one I pulled out of this car. It's a good box. The one to the left of it is an '82 close ratio. I may install one of these to begin with. When it craters, I'll swap in a Z32 box. Here is the F54/P90 core that I will be sending back to Rebello. My messy benches with lots of stock and performance Z stuff that I have been collecting over the past year or so. More when the engine comes in...

    Very cool, thanks for sharing! I have the impression that it is an expensive process to develop the tooling for casting. Is that not the case anymore.i don't expect that I would produce very many of these. Cheers, Ross

    Welcome! Very nice car!

  9. That's good to know!
  10. Stokked, Welcome to Hybridz! That seems high but I haven't priced an engine build since 2008. For reference, my Rebello (Google it) built long block wasn't much more than $5K back in 2008 for a long block build with forged internals, custom cam and mildly ported head. You can do the math. I'd recommend shopping around, and be sure to read about HZ member experiences with California Datsun. I believe they used to be called Datsun Parts. Good luck with that! Not personally, but search around there are quite a few people who have paid for their services. Search and form your own opinion about California Datsun, a.k.a Datsun Parts. Talk to Rebello Racing (or read more HZ) and get ready to open your wallet. You won't be able to run pump gas with that kind of compression. It's all here, right at your fingertips. I certainly don't have the time or will to spoon feed information maybe some other nice soul will. FWIW, the best way I've found to search Hybridz is to open a new tab, go to Google type in your search term followed by "site:hybridz.org". For example "250hp l24 site:hybridz.org" results in this post: Lots of good information in there. Good Luck!!!!

    I developed a 280zxt rotor cap for my car. I'm considering printing/selling more. Let me know what you think! Here is version 1.0, test fit on the dizzy. I didn't spend much time making it look good, just testing the fit. Turns out it fit perfectly. Here is version 1.1 as-uploaded to my print queue. I spent a lot of time sketching the "Z" and optimizing the look. My printer is a Markforged Mark Two. The material will be Onyx, a chopped carbon infused nylon. I'm not sure how well it will stand up to engine heat. My other option is Stratasys ABS although, if I sell these I'll farm them out so there are many other options including metal. They could also be machined but the Z will be difficult to produce correctly due to the tiny radii. Any feedback is appreciated!

    New to the Z world! Wanted to say HI!

    Those bumpers and the trim will just unbolt and you'll be left with fresh matching paint underneath assuming he previous owner removed the bumpers to paint the car. 240 bumpers will cover the holes, you'll just need to get some adapter brackets for mounting the bumpers or make your own, it's not difficult if you have decent, basic fabrication skills. Motorsport Auto sells aftermarket air dams and bumpers in fiberglass and carbon. A lot of people just paint them flat black and bolt'em on. Looks pretty good in my opinion although I'm not a fan of the side skirts and rear dam. I ran no rear bumper with the holes exposed and a flat black Type II front air dam on my 280z for years. I liked the minimalist look.

    As for starting it, first you'll need to drain and flush the fuel system. I'm sure the carb bowls are full of gunked up old fuel. A lot of people ditch the flattop carbs in favor of the older style round top SUs although I've read that if you know what you're doing you can get the flattops to run well. Personally I'd start planning for fuel injection and Megasquirt or some other aftermarket FI.

    New to the Z world! Wanted to say HI!

    Welcome! Must be a very late production date as those bumpers are the same as 75/76 280z's with fuel injection. I assume you plan to modify it since you're here. The first thing I would do is ditch those bumpers and bumper shocks. You'll lose close to 100 lbs that's hanging off the extreme ends of the car.
  16. Yah, me too. I've seen at one other person on HZ notice the issue. Maybe others just don't realize it's moving around. I also found it ridiculous that T3 put the cut-out for their logo right in the load path, further reducing the stiffness of the mount.
  17. Your bracket looks like it will hold the load much better than that flimsy T3 bracket. To drive the point home all you have to do is run some simple numbers. Lets assume your engine will be putting out 400 lbs-ft of torque at the crank with a 2.66:1 first gear ratio, 3.7:1 differential, and the mount is 6" from the center of the output flange. With that setup your engine will be applying (400 x 2.66 x 3.7) / .5 = 7,873.6 lbs at that interface! And that's just constant load, not considering the dynamic effect when you dump the clutch from a stand still. That case would be at least 2 times higher. To make things worse, the t3 bracket is cantilevered so you're applying that load in bending on chassis mounts that were designed to take the straight pulling load from a stock, ~150 lbs-ft engine.

    Valve cover issues

    I didn't. RTV will eventually break down but it's soft so it may be OK.
  19. Autopower makes more than one version for the S30. I recently purchased the one that attaches to the wheel arches for ~$500 from MSA. http://www.thezstore.com/page/TZS/PROD/50-1924

    Valve cover issues

    Of course you can. Underneath the larger blobs of epoxy are screws that you'll have to remove. I cleaned all the epoxy off mine, and just reinstalled it without the epoxy. Use Loctite on the screws. I'm not getting any excessive oil in my catch can. This is a common issue with these old cars. Search around to see what others did.

    The holes in the rails are currently just plain holes. I just purchased a cool rivnut installer so I'm planning to drill it out for 1/4" rivnuts. Regarding the angle, I just used 1x1 angle, tacked it to the sides then welded on 14 gauge to the side to tie in the floors. If I did it again, I would just use 1x2 as you mentioned. The challenge is getting the angle to fit on all sides to the irregular shape of the floor. I made many, many trips back and forth from the car to the bench grinder. Probably should have just clamped the grinder to the floor pan in the car to save myself so many trips! If you're that tall I wouldn't recommend using S2K seats. They sit very tall even with shortened rails. I'm a tad under 5'11" but have a long torso. I can only get 3 fingers between my head and the headliner.

    Update time! I've been working on the Z intermittently, the inside part of the floor pans are painted and ready for sound damping. I'm currently working on the underside, wire brushing the surface rust off. I'll follow that with Ospho, etch primer then finally 3M underbody coating. Top side of the floor pans done... Test fit the S2K seats...yah these are gonna work Oh, and I got my son his first car, a Z of course 2004 with only 37k on the clock. Spoiled rotten kid!
