  1. This is my Schwinn Suburban 5 speed circa 1973. This was the last bike I had before I got my drivers license. And once you have your license and a car who needs a bike! I saw this on ebay about 5 years ago and figured what the hell and bought it. The last time I rode it was a few years ago but it rode like a new bike.Too bad I can't afford to replace the Apple Krate I had before the suburban!

  2. I’ve had the Datsun Competition Parts “quick steering knuckles” (which are 10mm shorter than stock) on my 260Z for over twenty years and they are definitely a worthwhile improvement.

     

    I have the same ones on my car and for about the same time period.

    I'm happy with the feel. It takes a bit of hefting while parking if your not rolling but it's not too bad at all. I wouldn't change back to stock.

  3. My machine is giving me fits and my wife just had back surgery so I'm dealing with that as well. Fortunately she can wipe her own ass!

     

    I'm inundated with work right now which is good for me and bad for the HybridZ community. At this point I have no idea when I'm going to be able to produce some more stuff.

  4. I've been in need of a KA24DE lower intake manifold, but haven't been able to find one up here.

     

    I've been tinkering with the notion of casting a new one. I've casted before, but not with something so large.

     

    Would there be any benefit in casting in bronze, as opposed to aluminum?

    I wouldn't think that there wouldn't be much of a heat issue, since I have the upper portion, which is aluminum.

     

    Reason why I ask about bronze is that I can easily melt some down with my oxy/acc torch, instead of going to a foundry for aluminum.

     

    I don't have time to get into the ins and outs of it but no, using bronze is a bad idea.

    I'll give you the same advice I give everyone else. Find a small foundry (does not need to be near you) that will work on short run projects. Learn how to make the patterns (which you have to do anyway) and leave the pouring to the foundry.

     

    If you read the three threads I have on casting my EFI manifold you will have a pretty good idea how to get it done. The info is all there.

  5. I forgot to post why I have central locking...

    I shaved the door lock cylinders. The door looks a lot better without them. I still have a key to the hatch and if there is ever a problem I can reach in through the open hatch and unlock.

    Sorry no shots of the finish product. It's raining out!

    Edit: One other thing I did. By removing the lock Cylinder and then installing a metal shield over the latch there's no way to get in there with a slim jim.

  6. I saw this on another site and it worked like a charm. Use a coping saw. Drill a 1/4" hole through the rubber. Pass the saw blade through the rubber and attach to saw. Saw out the rubber letting the blade wipe against the outer steel bushing. It was really simple and I was using some cheap harbor freight blades I had laying around!

  7. The president directed the secretary of transportation to publish higher fuel economy standards for the model-year 2011 cars and light trucks by the end of March, and to re-evaluate the proposed standards for future model years. Automakers would generally begin selling model-year 2011 vehicles in fall 2010.

     

    Should of happened years ago. Then there would be more gas for us!!

  8. Well I made it back safe and sound!

     

    It was great too finally meet you guys face to face as well. Your pop seems to have quite the Z history. That poor deer.

     

    I put about 500 miles on it and it ran flawlessly. I wish all of my projects worked this well. I ran the car at about 75 or so the whole way down and back, using cruise control of course, and it was very comfortable. At this point I no longer worry about the EDIS or megasquirt letting me down.

  9. Sounds like business is good. Do you make castings from photo-overlay, or impressions? I imagine doing stuff for Disney could be lucrative, tho I hear they're slow to pay, at least the movie side of things.

     

    The stuff I bid on for Disney is reproducing a bunch of existing castings. They'll supply me with an original and I'll scan it with my 3D laser scanner. Then I'll derive a pattern from that scan.

     

    So how many sets do you think you'd need to sell to make it worth your while? You were thinking like $2k for a set right?
    Have you been reading my notes?

     

    At this point that's the range for the manifolds machined with throttle shafts and butterflies. Everything else will be À la carte. It will have to be an exceptional circumstance for me to sell a raw casting.

     

    I'm waiting for the economy to improve and then I'll make some decisions as to my long term goals with this thing. I'm lucky to have steady work right now and I'm not too inclined to take any big risks at the moment.

    Derek: To quote a famous line in a Movie "If you build it, they will come" You have a product no one can compete with, you are in that Proverbal Ball Park all by yourself! :)

    You just want me to bring this to market because the price for your setup will seem like the "bargain of the century" compared to what I'll have to charge:)

  11. Yea what Tony said!

     

    I'm not really sure how I came up with that 1.495 number but it was probably a material issue. I had to bore the stainless pipe I was using and I had to take it to 1.495 to get it clean. the manifold then tapers down to the stock port size. I think it's 34mm.

     

    In My opinion the CAM pogram I use is no more difficult than Solidworks. And CNC machining is much simpler than traditional machining.

     

    As far as selling manifolds I still don't know what direction I'm going with these. The egomaniac in me would love to have people driving their cars with these manifolds but the businessman in me say's STOP. The patterns would need to be reworked and the core boxes are total sh!t so I would have to re do those. I'm not a "your on your own" kind of guy so I would feel responsible for helping people achieve success with their manifolds. And that can be costly.

    Awesome work Derek. Really, really cool.

     

    Have a few questions, i hope you can answer them for me.

     

    How hard is the CAD-CAM part of the pattern making? I would love to make parts like this, and am reasonably proficient at Solidworks/Inventor, although i have never played around with CAM packages. As i understand it, it is not as easy as just sending the model to the CAM package, and then to the CNC mill?

     

    I see you are using 1.495" diameter butterflies. Is there any possibility of putting larger butterflies in for a bit more of a worked-over L series? Say, 1.69-1.77"?

     

    I would be very interested in buying a set of non finished castings off you if you ever decide to sell some. I like the performance, sound and style of triple Mikuni setups, however i don't like the tuneabilty, economy and hassle of them. I really like the overall package of your setup. I was considering making some custom ITB's, but went against it as i felt it wouldn't suit the style of the car. I feel yours fit the car perfectly.

  12. Derek, That is absolutely stunning! ave.gif Sorta has that era period, full tilt factory backed race car engine appearance! If Nissan themselves campaigned a 240-Z with EFI, THIS is how I envision it looking! Incredible! bgiorno.gif

     

    Thanks Paul

    That's exactly the look I was going for. The best part is though it actually runs. And I don't mean it runs at full throttle and everything else is a compromise, It runs great period. Sitting at an idle, cruising in third gear at 2500, lugging in fourth gear when you should be in third. I'm running extra code and it even brings the idle speed up when I turn on the A/C!

    I wish I had the skill and the time to properly tune it because there are some areas that I think could be better.

     

     

    Holy speechless...that is simply amazing, beautiful, beautiful work. Love it. Your attnetion to detail with the fuel lines and throttle linkage is nothing short of breath taking. What engine mangement are you running with it? I bet it sounds incredible especially at WOT.

    Thanks Yasin

    I thought you were following the build thread I had going.. Hell I with my ego I figured everyone was following it!

  13. Time to show off my manifold

     

     

    I'm going to be in the West Palm Beach area this Tuesday evening the 12th. I'm driving my car down so if anyone is interested in meeting up somewhere let me know. I'll be in the Blue Heron I95 area.

     

     

    The manifold I speak of
