  1. Dave,

     

    I've got a set I can donate for the cost of shipping. I probably won't have time to ship until early next week, if that's okay?

     

    To clarify, your subject line is plural, but your text says one. How many do you want?

     

    PM me your address if this works for you.

  2. Ron, that was one of my most favorite car rides EVER!!

     

    I've never been very scared as a passenger, but when you took me down Ten Eyk road that one time, I about pee'ed my pants!! :D

     

    Nice linear acceleration, and insane grip.

     

     

    :mrgreen:

     

    That car became the most overall capable street car I've ever owned.

     

    Anders and I worked together experimenting with different set-ups on each others M3's, essentially sharing the development costs and time. In a short period, we both ended up with very capable cars that were still everyday live-able. Not a bad way to go when you're starting fresh with a platform.

    That looks great

    But dont you need a dampner on the L series engines

     

     

    With all due respect' date=' yes, you do need a damper, unless you are planning to tear-down the bottom end of the motor after every few runs/outings (depending on how hard you are hitting it - ask Jeff Priddy) and have the budget to replace parts fairly regularly.

     

    Even on normally-aspirated inline four-cylinder engines, we have seen crankshaft journal flexing of two degrees or more with no harmonic damper installed, in our dyno/torsiograph tests. In serious performance applications, you can expect that much flex to shear cranks at the flywheel after a few laps in a road race environment. Inline-six cranks are notoriously worse (ask the BMW racers what they have been going through.)

     

    Anyone who wants to read-up on exactly what harmonic dampers actually do can click the link below for a technical document which our head of damper development wrote:

  4. actually they are mounted in a functional way, ALOT of drifters and racers mount them that way if you research on the net it IS so you can adjust slight camber AND caster changes.

     

    It is getting WAY more popular these day and you will start seeing more and more.

     

    Any adjustment that adds caster and concurrently reduces camber is considered functional in the drift world?

  5. Stop it. Just stop.

     

    This thread is terrible and I don't even know why I bothered looking at it. I was toying around with the idea of getting an E36 as a DD a while ago but now I think you've sealed my fate. Jerks.

     

     

    We aim to please :wink:

  6. While Bart has been fun, quite honestly, it doesn't 'drive' all that civilly. The rear of the car is squirmish and unpredictable. The 37 year old bushings aren't helping much. The front, despite the new BJ’s and poly bushings, is darty and unstable. I’ve tried various adjustment's with some results, but it's so far from where I want to be, I've resigned myself to a clean slate... sort of.

     

    BRAAP and I have been talking about swapping in the front end of an E30 BMW. We finally got around to meeting up at a JY and taking some inital measurments. Comparing the BMW layout to the 510’s structure (and SR), it was looking doable enough to take the next step, acquiring the mock-up parts. Back to the yard we went and pillaged an E30. A nearby friend donated a wagon to the cause (thanks Aaron!).

     

    Vice-griping the crossmember in rough position confirmed that this swap is close enough to take seriously.

     

     

    Crossmember & front view...

    Steering shaft is looking yummy...

    The more challenging aspects are looking to be strut tower rework and capturing the rear inboard pick-up's (lollipop's for the BMW familiar).

     

     

    Approximate postition of the upper strut mount, netting 1.5 deg. neg. static camber and 9 degrees caster...

    Lollipop area...

    Installed in this oreintation, the geometry is very close to the original BMW E30 spec, with a bit more static camber/caster added. And the frosting?... it's looking like this contraption will fit very comfortably into the pocket between the SR's sump and bellhousing.

     

     

    There is one facet of this that I would like to see work out better. Track width. The BMW suspension, when used with as high a backspace wheel that will clear the strut (with 15x7 wheels), is about 2 3/4” wider (overall) than what I would like. I decided I would rather run flares than compromise the geometry (with a narrowed crossmember). I’m leaning towards ZG flares, like Anthony (Supra510) has done with his wagon...

    On the bright side, the 1st Gen. Miata's rear double-A arm suspension is only about a 1/2" wider than the E30 front, and the wheel bolt pattern is identical... 4x100. Hmmmmm.

  7. You were impling that sequential was not a major feature worth worrying about

     

    Not quite what I said. Placing a major portion of your priorities on *any* single feature may not be the wisest choice. That's a bit closer to my intentions.

     

    I was saying what is the feature that mega squirt has that would make me buy it over another ecu that has sequential.

     

    Price, support, installation complexities, consistency, reliability, compatibility, software intuitivity (is that a word?), etc, etc, etc, blah, blah, blah, etc, etc, etc, etc.

     

    My point is simply, basing a decision on *a feature or two* is not something I would recommend.

     

    If i was driving around at 100% throttle all the time then i would save money and go for a batch fire , but the reality is no one actually does that

     

     

    Point taken. Driveability is a consideration for me, as well. Everyday driveability is not limited to sequential this-or-that. Sequential may be a contributing factor but it's not *THE* contributing factor.
