  1. Wait a second, you had someone donate a RT mount to the project? That's just hilarious if you ask me.

     

     

    Your entertainment is justified :wink:

     

    Probably three people know the history, so why not here?

     

    In 1997 I had completed and was campaigning the LT1/T56 powered 240z http://forums.hybridz.org/index.php?/topic/52346-lt1t56-240z/

     

    Bob Maggio had completed the same swap in a 280z roughly six months prior but, as far as anyone knows, it had never been done in a 240. There was no documentation and no HBZ.

     

    I was having problems tearing the diff mount. I don't recall how many mounts I tore or how many band-aids I applied. What I remember is, Friday afternoon, 'busting another'... with a race scheduled for Saturday. At the time, I was much more fanatical, and this was an EMERGENCY dammit! All I had on hand was some scrap aluminum, a MIG machine, and a local, cheap auto parts house. In desperation I built the ugliest diff mount in history. If you've ever welded aluminum with a MIG machine, you'll likely empathize with that sort of 'fun'. I was gun shy and concerned about tearing the isolators again. The long nose R200 has four holes right? Why not *TWO* turbo 350 mounts? So there it was, in all it's funk... two trans. mounts, on top of the diff, mated to a soda can bridge, a few hours before flag down. It survived the race.

     

    At the time, I was also struggling with driveline vibrations. This led to further experimenting. Pinion angles, lower contact areas, shaft material, and so on. In the end, I built a steel 'bridge' with a single, shim-able, GM mount. I was on mount number three or four by this time. It was simple and I was making progress.

     

    I don't recall the specifics, but I remember a few of us talking long distance. JohnC, Rags, Ross Corrigan, Pete Paraska, Jim Biondo, BRAAP, etc. This was before HBZ's time. In fact, it was before Internet forums were generally in vogue. Pete and I began discussing this very topic, and I shared my 'experiment'. He asked me to replicate it for him. So, I made ONE more, expressed my desire to avoid production, and asked him to keep the cost to himself ($20.00!).

     

    Pete kept his promise, and posted the mount and prints on his website.

     

    Regarding the donation, my relationship with Roostmonkey is top secret :mrgreen:

     

    The few I built for myself are destroyed. Does this make Pete's a collector item? :P

     

     

    In my best Paul Harvey impression... "...and now you know the rest of the story..."

  2. I haven't made any effort to keep a running tab. Even if I had, it probably wouldn't be terribly useful to others. I've been very blessed in that the 260 was virtually given to me, BRAAP sold me the BMW drivetrain for less than a 1/3 of typical pricing, my ties with Wolf resulted in reduced EMS costs, Roostmonkey donated an RT mount, I own a machine shop, so related work is 'free', and the list goes on. My out-of-pocket expenses aren't real-world reflective, so to speak.

  3. Couple more items off the checklist. Poly motor mounts arrived (Ireland Engineering) , and drive shaft is completed (Driveline Service of Portland)...

    A note on the poly mounts: Close friend has a stunning E30 M3 2.5 4 cyl, with a handcrafted turbo conversion. He tried the poly mounts from Vorshlag and they were not street friendly. He switched to Ireland Engineering poly and noise/vibration are much more tolerable. Enough so, that I'm expecting them to be not completely unreasonable on a 6 cyl. Fingers crossed.

  4. Funny, my sister in law gave us crap about buying a BMW saying it was an image thing and we paid for image and all that...

     

     

    Some people own BMW's because there is, in fact, a difference. Screw image. I want a skillful, tactile, AND pleasant car. Not many manufactures bare the fruit.

  5. The Engine angle looks a little steeper then the z motor but after losing my brain trying to figure out the angles you were mentioning about the position to line everything up im guessing thats the only way.. might be the pic angle too..

     

    The trans output shaft is within 1/8" of stock. The front of the motor is a bit higher than stock (at the crank damper). In angular terms, the BMW drivetrain is 1.4 degrees more inclined. Combined with an adjustment of pinion angle, I should have driveline geometry equal to, or better than stock.

     

     

    Great beauty, great union.. Great Photo!!!

     

    :cheers:

  6. As a owner of a 77 z and a 97 BMW 328IS i am really really really really looking forward to the supercheap well built completly turnkey kit you will surely be selling this week to swap the bmw motor in to my beloved z...

     

     

    Absolutely. Please deposit $19.95 in my paypal account :wink:

     

     

    more posts and pics please =0)
