  1. I have several things for sale I have removed from my Z over the years. Everything is located in New Jersey and mostly negotiable (I'm not up to date on most of these prices so here's what would make me happy).

     

    Weber 32/36 DGV carburetors with E88 manifolds, balance tube and linkage that should be complete.

    These could probably stand to be rebuilt but did run when I took them off ~2 months ago to install triples.

    $250

    Unused Cannon triple Weber DCOE manifold with linkage and carburetor mounting/insulation kits:

    Old Canon exhaust manifold. My research tells me it is a Canon manifold which haven't been produced in some time. Comes with a collector to a 2.5" exhaust:

    $150

    Four Eagle Alloy wheels. My last measurement put them at 7.5" wide with 4x114.3 and 4x100 patterns. All of the tires pictured with these are 225/50R15. Two of the tires are badly scalloped although the other two are Toyo Proxes4 and in decent shape. The tires can be dismounted and discarded if desired, I don't expect anything for them.

    $200

    240Z master brake cylinder. Came off my '72. No leaks or bleeding between seals when it was removed around May. I went with a 15/16th's cylinder for bigger brakes:

    $50

    240Z distributor with a Pertronix electric ignition conversion box and 3 year old NGK plug wires. Upgraded to a 123 Ignition unit:

    $75

    Finally, the pièce de résistance, one fabulous aftermarket 'Z' steering wheel. I don't know a thing about this other than it will bolt right in place of a factory steering wheel and use the original horn contacts. It was the first thing I took off my car so a $20 bill would thrill me:

    $20 SOLD

  2. If you decide to do adjustable suspension at any point I can vouch Techno Toy Tuning as rossman has said. Silver Mine Motors has a ton of brake options at a few different levels and price points like jhm said. Only thing I could think to add that hasn't been mentioned is Apex Engineered. They're still new but fantastic quality from my experience and if you ever want to do an engine swap their cross-member has swap-able engine mount points.

  3. WTB a triple carb setup. Preferably something complete but willing to entertain partial sets of just carbs or just a manifold to put together something unique.

     

    I had ordered new OER carbs a week ago but RHD Japan decided to tell me after I placed my order and they approved it that the price had gone up a few hundred dollars so I'm searching for alternatives. Thank you.

  4. It definitely wasn't easy to get a decent reading. With the engine fully dressed and in the bay I didn't have anywhere good to attach a dial indicator or have a magnetic base handy so we ended up making this jerry-rigged contraption to hold the indicator in a good position. It uses two bolts from the cam cover to hold itself down and worked well for something thrown together. Figured someone might get a good chuckle out of it here...

    I'm sure they'll be fine. I guarantee the buying has only just started though! 

    Tell that to the 123ignition distributor sitting next to me and the fuel fittings going out today! There's suddenly a lot going on at once for my Z.

    Regarding measuring the cam, did you measure directly on the cam or on the valve?

     

    0.050" on the cam equals  ~0.075 on the valve.

     

    This is also not true because your lash will affect the real lift as well.

     

    How do you find exact TDC with engine in car? If it's a cam with fast lobes a 5 degree difference will make a huge differnce. My current cam has about 0.006" lift per degree change during it's opening phase. 

    I was trying to measure directly from the cam which is probably why I was getting such strange numbers then. I imagine a proper valve adjustment would be key in measuring real lift since lash has an affect on that measurement as you mentioned.

     

    Also, and you'll have to excuse the ignorance of youth and lesser experience, but because I was originally only trying to find the lift and duration from on the cam I figured TDC was irrelevant to this case; only the starting and ending degrees of the measurement. I wasn't trying to degree the cam itself or change cam timing, just to get a better idea of what cam is in there since that was the original direction I was pointed to in picking a starting venturi set.

  6. Thank you jonbill. That makes good sense to me. In my use I wonder if I should go with a slightly smaller venturi. Using Frank Honsowetz's method and considering I don't really go over 6k on the street I came up with a 34mm venturi size:

     

    sqrt(458.79 * 6,000 / 1,000) * 0.65 = 34.103

     

    Even though this would probably limit the 6-7k range, my cam definitely doesn't have any hidden power up there and if the slightly smaller size makes for easier tuning and or more driveability then that tradeoff could work.

     

    However if that 2mm reduction in size would affect things across the whole rpm range then it may be better to stick with 36mm.

     

  7. I am in the process of picking out new carbs for my 240Z with a 'Stage I' Datsun Spirit motor. It's an L24 based 2.7L stroker that has been (in my opinion) burdened with the Weber DGV setup that came with my Z. At the time of setting up this motor I found myself unable to replace the carbs the car came with but I'm now in the position to do it right. After some back and forth I thought I would go with some Z-Therapy SU carbs since they should be plenty for the engine and I've heard nothing but great things about them. The problem is I don't really have 4-5 months to wait for a set.

     

    I also don't have experience with sidedrafts which would be my second preference. So after reaching out to a few people and dredging old forum posts I got in touch with Josel from "SidedraftSpecialties" in CA about getting a new set of 45mm OER carbs. He explained to me that the most critical choice in picking a set that will run well, particularly on a mild 2.7, is the choice of venturi size which would naturally be based on the size of the camshaft. So here's my problem:

     

    I don't know my cam specs. I've reached out to Datsun Spirit who even found my old measurement and spec sheet which was able to narrow things down to it being a "DSI274 non drilled cam". Unfortunately he didn't seem to have a cam card anywhere for this particular cam or recall the lift and duration. The cam itself has "Japan" and "E30" in raised letters along with an "A" stamp near the firewall so I'm assuming this may be a re-grind cam. After deciding to measure it myself I got (I think) inconclusive results. Using a dial indicator and measuring directly on the cam in the car I found an intake and exhaust lift of .317" but a duration of 195 degrees measuring from .050" of lift from of base circle back to .050" of lift. I could see the .317 lift because the engine is pretty mild but the 195 degree duration doesn't make sense when the original "A" cam specs I find say the original duration should be about 248 degrees. I tried measuring from .006" to .006" which gave me 289 degrees which seems a little long for a mild cam. I could assume that "DSI274" refers to a 274 degree advertised duration, not too far off from 289, but we all know what happens when you assume things.

     

    What am I doing wrong in this case? It's been a few years since I had to measure a cam but I feel like I'm missing something. Should I be measuring duration and lift from the moment the rocker arm moves from and back to .050"? Or does taking these measurements straight from the cam base circle suffice? Was the advertised duration of these L-series cams based on a standard before the .050" standard I remember being taught about? I appreciate any advice at this point because time is a factor for me but I'd rather do it right in the end.

     

    EDIT: I'll eat some of my own words before someone else makes me.... Just found this wonderful thread about cam timing with a degree wheel and dial indicator by BRAAP and others:

    Pretty much narrows my questions down to should my .050" measurement always be taken from the top of the valve retainer?

     

  8. I'm not sure what it's worth but I'm interested. From what little I found on them at jdmjunkies it looks like they're from

    FET / Far east trading / Kyoku-To

    Later versions came branded as F.E.T. and had the additional Balancer tube on top. This is what i got for my car. I heard the balancer tube makes idling adjustment a bit tricky but i got it mainly because of the finned design will fit my Kakimoto valve cover excellently.
    Compared to some other brands this one has very short funnels which is great if you don’t have much space.

     

    I would also like to find a finned Kakimoto or Kameari type valve cover eventually and this would go great with that and the OER's I'm about to order. Shoot me a PM if you want to just sell it and we'll see if we're close on value. As far as coilovers I'm not sure what you're looking for but if you need some original cores I have a complete original suspension with struts and control arms that I would be happy to trade for.

  9. Because there aren't enough options for you to choose from already, I run Joe Gibbs Driven conventional 10w-40 break-in or hot rod oil on recommendation from my engine builder. I have a Datsun Spirit 2.7L 'stage 1' motor and the car seems very happy with that syrup. It is $10-11 a quart off amazon and supposedly the 'hot rod' oil is the 'brake-in' oil with a different label for the same price.

  10. I'm fortunate enough to have a garage for winter storage right now so salt and rain really never touch the car. It's the unexpected 10-15 minutes of standstill traffic that's all to common in NJ that has me concerned. I think I'll try to fab up a plate to go between the tank and pipes once I go ahead with the kit. Two different layers of air should be plenty of insulation even if I end up sitting in a little traffic.

  11. Hello everyone! I'm doing a slow restoration on my 1972 240Z and I'm at the point of sorting out the exhaust. I believe we're going to go with the twice pipe setup for 3-2 headers from thezstore.com. This kit from what I understand recommends that you widen the opening in the rear fender to accommodate both pipes which is something I definitely don't want to do. My solution would be to modify the piping in the kit so that I have a center-exit exhaust which would go with the retro-racer look I'm after with my car.

     

    The only concern I have would be that there would be more heat in a much closer proximity to the stock fuel tank. So what would be the best insulation for the exhaust? I would assume header wrap would be plenty being that far down the exhaust system. Any input is greatly appreciated as I'm used to lifted trucks with miles of space between everything.

    Thanks in advance!

  12. ^^^just a hint, the time to visit your local Z-Club is BEFORE you spend all the money!

    Since my last post I ended up with a Datsun Spirit STR Stage I engine (based on an l24 block rather than an l28) with some extra goodies. I feel like it'll suit me pretty well for where I am and the driving I'll be doing with it. I did have a budget which I went slightly over for the engine, but I'm still plenty well enough under my overall budget for the car. There's nothing left I can't handle now and hope to have the car back on the road in two or three weeks.

  13. Thank you all for the information. I think this was just an unfortunate case of a new cam being rounded out. I've decided to do a complete overhaul/rebuild with Eiji at Datsun Spirit and will be posting a hopefully lengthy thread about it after it's all done.

     

    IF they put an internally oiled cam in, and just put bolts in the spray bar mounting holes, the oil feed holes will still be open. You need to either swap the cam towers from an L28, or make some block off plates for the oil holes. Motorsport has them too.

     

    NJ has a pretty active club, with lots of knowledgeable Z owners: http://www.njzclub.com/

    And thank you z-ya. I can't wait to drop into one of their events when the cars all finished!

  14. Thanks for the info guys. Definitely comforting to know the internally oiled cam was just a good alternative. Looks like I'll be shopping for a machine shop to get this head rebuilt. Datsun spirit is close enough but it's a shame I haven't found any reputable Datsun shops in NJ yet. Really slim pickings here in general.

  15. Hello! I'm new to the forum and Z ownership. I have a fairly clean '72 240Z that's having some engine issues. It's had a very noticeable valve train tap since I brought her home about three months ago. I decided to pull off the valve cover last week to discover the camshaft is being rounded out. Fortunately I put less than a hundred miles on it since I acquired the car and now have the engine bay most of the way apart. The previous owner claims that the top end had been rebuilt a little while back, but then the engine smoked so he later had the bottom end rebuilt. Unfortunately the previous owner has since passed away and I have no records of what or where the work was done. My suspicion is that the top end of the engine was not rebuilt correctly. All the pictures of E88 heads that I've seen have externally oiled cams with oil squirting rails on them. When I pulled off my E88 head I found an internally oiled cam and shiny new bolts where the oil rail should be. Does it make sense that there should be an oil supply rail there? If so does anyone know where I can find a new one?

     

    Also, if I end up going for a complete overhaul and decide not to do it myself, what's the best option as far as well known Zcar engine shops go? I'm definitely attracted to Rebello and DatsunSpirit. Unfortunately I can't seem to find anyone on the east coast.

     

    Thanks in advance!
