  1. ...He took it to a driveway mechanic to have a blown head gasket repaired and some "other performance stuff" installed. The mechanic moved before the work was finished and took the car with him. The owner couldn't track him down but inexplicably never reported it stolen. There was also no mechanic's lein on the car.

     

    Pete,

     

    If it makes you feel any better, I had something similar happen to me when I wore a younger mans shoes... I had purchased a rolling chassis '64 El Camino from a relatives friend. It sat in his yard for a number of years and he had never titled it. Shortly after purchase, I dropped it off at a paint shop, along with a deposit. A couple months go by... I swing by the paint shop and its gone... vanished... the car, the paint shop, and the owner.

     

    By the time I figured out what happened, and where the car went, it had found a home at a private lot. This person decided that the car was far more 'his' than mine and filed for lost title. I spoke to him and his wife on the phone a number of times over the course of a week... he refused to negotiate. To this day, I have never met a more self-centered person.

     

    Because I had not yet titled the car in my name, I never received the DMV's notification. And, because I can't prove that the painter never intended to paint the car, I can't prove that he stole it.

     

    My negligence cost me around $4000 and a fair amount of grief. You can bet I wont do THAT again.

     

    I never found the painter. Through lots of legwork, I discovered that I wasn't the only one looking for him. His name was Corbin May... if any of you know of him, I should like to 'thank him'.

     

    Though it doesn't sound promising, I hope it works out better for you.

    There are a couple more escaping my thoughts at the moment...

  3. does anyone have any ideas on modifying NA 280zx dizzy for the 300ZX sensor and chopper wheel? i tried yesterday with one of my extra dizzys but it didnt work like i thought it would.

     

     

    You're not giving enough information on what part isn't working out for you.

     

    More than one person has done this swap... why not ask this question (with some detail) on the thread that's DEDICATED to this conversion?... http://forums.hybridz.org/showthread.php?t=91250&highlight=z31+MAF+swap.

  4. and about the CAS, Isnt the CAS just making the firing pulse the correct length?

     

    Not at all... its job is to provide positional information to the ECU.

     

     

    so does the ECU need this signal for anything else besides the ignition itself?

     

    Yes. It needs it for 'everything'... its the KEY component. You can't replace it with a categorically different sensor and expect the ecu to 'understand'.

     

    If I correctly understand which Crane system you have, it will not provide the information that the ECU needs to function correctly.

     

    A more direct approach would be to start with a 280zxt (late model) distributor, which has a CAS built in. This dizzy will 'bolt on'. Then, per this thread... http://forums.hybridz.org/showthread.php?t=91250&highlight=z31+MAF+swap, adapt it for your intended use.

     

    HTH,

  5. Im using a Crane Cams Optical ignition instead of the 300ZX crank angle sensor. (#1 if anyone knows that this is wrong let me know because no one has done this before)

     

     

    In addition to the item's mentioned by BRAAP, I would ask...

     

    ...a Z31 or Z32 ECU?

     

    ...One of the things the Z32 ECU is looking for (and likely the Z31) is a 5-volt square-wave from the CAS. Another thing its expecting is increasingly longer slots per cylinder, as well as a 360 tooth 'outer count'.

     

    I haven't personally scoped the Crane optical system... is it a square wave? What voltage? Are you getting this wave-form straight out of the pick-up?

  6. what are the pro's and con's of a car with MS installed with tps only or map only or map and tps?

     

    in a turbocharged aplication?

     

    'TPS only' is often referred to as Alpha-N (TPS + RPM). It works well with NA, hot cammed engines, as erratic idle can cause erratic manifold pressures. Sometimes a restrictor is enough to 'calm' the pulses.

     

    HOWEVER, in a turbo application, straight Alpha-N doesn't work. This is because a given amount of TPS doesn't correspond to a given load. In other words, A TPS, used as a load sensor, can't tell the difference between 1 psi and 20.

     

    This is where blended mode comes in... some systems allow Alpha-N to be used below a threshold, transitioning to MAP, above.

  7. can I run without a TPS altogether.

     

    My MS experience is admittedly limited. I understand that MS will allow using Map-Dot for accel enrichment. I haven't personally tried this with MS, but I have with Wolf3D. It works fairly well. Albeit not perfect (and dependent on cam(s), filter rates, TB, plenum, etc) but certainly do-able.

     

    Other possible omissions are (as you mentioned) clear flood mode, data logging, fuel cut, and auxiliary functions (potentially significant).

  8. ....If you were to put a piece of plywood in place of the radiator... and stood the car on it's tail... it should hold water flush to the grill opening.

     

     

    Sounds like that little rubber seal on the upper core support, thats gone from more S30's than not, needs to be re-installed (or maybe improved?). Did you have an opportunity to mess with, or look into its effectiveness?

     

    Thanks to all those that participated/contributed!!!

  9. Then of course ive never heard of pistons giving off light as a source of heat.

     

    ...and I've never heard of 'painting' pistons.

     

    Who knows maybe the ceramic coating just helps shed oil faster so the hot oil doesnt stick to the underside of the manifold .

     

     

    Now I'm confused... are you talking about ceramics or paint?

  10. Doesn't add up to me... painting something a color to gather heat or reject it implies that the heat is a light source.

     

    Paint two blocks of aluminum, one white and one black. Put them in a dark oven and they're temperatures will follow each other.

     

    Put the same two items with a 500 watt halogen bulb pointed at them and they will become two different temps.

     

    Obviously, under the hood, the heat generated from light is pretty well negligible.
