    1982 Caprice 5.0litre engine. Check Rockauto, you'll see a huge selection of 10SI alternators available. Clocking is 6:00, which means the top mount is 180 degrees from the lower mount. Most are 63 amp.

    There is one listing in there for this thing, Might work for us.

    PURE ENERGY 7127SW3 Click for more information about this part

    Remanufactured

    GM Universal, Single Wire, 63 amp alt.

    Here's the thing. None of them are 100+ amp one wire alternators. But it's the right case, and all it takes is a 12v wire to the exciter terminal to get them to work. It's a way to get back on the road in 60 minutes rather than 3 days. That's all I'm trying to do, give us options when traveling.

    I wish I could find autoparts that last 150,000 km, but that does seem to be realistic in this part of the world. I'm also not interested in originality, I'm interested in maximizing my enjoyment of my Z and doing everything I can to ensure I take whereever and whenever I feel like without fear of left on the side of the road when I can't get a super quality Nissan part.

    BTW, re not being able to find Podunk on the map, Poduck un-incorporated and closed as a townsite in 2011. Seems the AutoZone closed and it was the major employer in town, and it couldn't maintain liquidity. Sad, this is happening all over the US and Canada as small towns struggle to keep their young population from moving to more lucrative bigger centers

    Long term update:  The alternator listed here and the one that fits the 1982 Caprice use a 10.414mm (0.41in) wide belt, and my Z motor uses a 13mm belt system.  The actual belt that zKars used is a 13mm (1/2") belt so the original instructions are correct but this cross reference section is not.  Initially the 1982 Caprice alternator bolted right in and with a thinner belt it seemed to work OK.  Under heavy load, perhaps due to my 3.0 Rebello motor, the thin belt gets thrown.  I was able to source a replacement pulley and am happy to report that with the correct pulley everything appears to be working correctly.  I attempted to find a better cross reference with a 10SI alternator that came with the correct pulley but I never found an OEM equivalent, though I did find several advertised for tractors that looked right.  Here is the pulley info:

    +1 for a lighter flywheel.  I have an aluminium one that is a lot of fun to drive.  Takes a minute to get used to it but that's it, then "vrooooooom, vrooooooooom!" like a street bike.

    +2 I also have one, a Fidanza mated to a centerforce.  I love it

    Did you leave the dished pistons or go with flat tops?  I'm curious as to whether I can swap out my dished with some flats from a ZX motor and top it with an N42 head I am currently running without any problems from too much compression on pump gas.

    Thanks for a reply.

    Is got 89mm Nissan KA24E pistons in it.  They appear to be "reversed dome" style dished pistons.  Also remember that here in California the highest octane fuel available is 91, and its got ethanol in it.  While I only use the best (garbage) gas available it runs fine in day to day usage.  I also told Dave that I prioritize daily driving over power so he may have chosen dished pistons to match that request.  This thing makes plenty of power without flat tops so I have no regrets.

  4. My Rebello motor is an N42/N42 combo at roughly 3 liters.   Even 3 years ago neither Rebello or I were able to find a serviceable N42 head.  We sourced 5-6 of them but most were degraded past what could be used.  Luckily my car already had an N42/N42 setup so instead of swapping motors with a replacement he rebuilt what I had.


  5. The claims that seafoam is a mechanic in a can or cleans up carbon in one shot are dubious, but the stuff has its place.  I use a bunch of it on my dirt bikes here in California, home to high ethanol content gas that was never approved for use in my dirt bikes.  Ultimately the stuff is a solvent that burns well enough to use on fuel systems.  My typical use is cleaning out bike carbs but I also find that if I drain the carbs before storage and also spray some sea foam up the overflow tubes they don't clog up in storage.  Other chemicals probably work just as well but I find in this application seafoam does work better than WD40

    I think if I was going for a non-240z, surely the 280z would be the better option as stated from @rturbo 930they seem to be the best built?

    Frankly the 260z is almost completely overlooked outside of the Z community.  Like @rturbo 930 said the 280 headed towards GT car style in that its longer and heavier.  To me 280's feel more 80's techno-fantastic vs the 240/260 vintage feel.  The 260 is an improved 240 instead of a whole new car like the 280.  

    My 260 has 240 bumpers on it and even people with Z's assume its a 240 because they haven't seen a 260.  From the outside I think the only give away is a different set of tail lights.

  7. OP:  Are you familiar with the 260z?  They get a bad rap because the motor was choked down with emissions compliance and the bumpers were larger, but you wouldn't be dealing with those things on a modified car.  The way I see it a good 260 is a 240 with upgraded electrical and a stiffer chassis.  I'm getting close to putting mine on Bring A Trailer

    Dave Rebello will built that engine for around $7,800 with not core parts, if I am not mistaken. I would like to know what the dyno output is on this engine. Looks like a good deal if that is the style Z you are interested in. 

    Pretty darn close, ask me how I know.  My motor is very close except for the cam (Rebello custom vs Isky) and Dave estimates it a 285hp+ on SU's and he claims 300+ on triples.

  9. Verify your fan clutch works.  I also drilled 2 1/8" holes in my new thermostat when i had a similar problem in my Z.  It allows the warm water to surround the thermostat a bit easier and in my case it started opening correctly.  Its an old hot rodder trick and supposedly not necessary with a good quality thermostat but those seem to be hard to find.  Google it
