    Thabks @Datz44. I am running square setup 15x8 +0 225 50 R888. I'm considering 235 or 245 on 15 if I can find a wheel that will fit over my brakes

     

    I was thinking that to, size 235 on 15*9. Thank for the feedback! I like the colour choice. It was my initial choice then decided to stick with blue as the original colour.

    @Datz44 thanks friend! I think you should decide one of the following courses:

     

    1) race in an SCCA class w/ very very specific rules

    2) race in a vintage league. Less competitive and the rules are really loose. 
    3) build whatever you want, and just enjoy track days, time trials, etc. 

     

    your decision on what car to build and how, will be very dependent on this decision. 
     

    If going with #1, definitely go for the 240z. It is one of the most competitive weight/power potential in the production class. If going for #2, id buy a cheaper 280z chassis and lighten the heck out of it. If I was going for #3, I’d buy the various panels and build a tube-frame from scratch. The only component I have not found so far available aftermarket in fiberglass is the roof. Every other exterior panel is available. 
     

    I think the ultimate track Z (just my opinion) is a full tube frame, with flat panels in either AL or fiberglass. I’d look at a Honda K24 engine w/ a small quick-spooling turbo. I would source forget aluminum hubs and control arms, make my own crossmembers and subframe. I bet you could get the weight down to 1700lbs, and still have 350+hp to play with. The problem is, it will not qualify for any class that I am aware of. If it does, it will likely be uncompetitive without some serious aerodynamic mods. 

     Thank you for the advice. I'll look up the rule book for each choice. 

  3. @AydinZ71Nice work!! I admire the beautiful work. I began HPDE (2 events: Nelson and Mid-Ohio) this month with my daily (Elantra GT) and I'm thinking on a stock track car. Something to will eventually spank Porsche's on the straights with work.😉 The Elantra is doing that on corners 😇  I'm debating on putting the 240Z (blood, sweat and tears+love) on track or get a 280z (rust resto then track build with more track experience in it) + storage. I'm learning a lot from your blog/forum!

  4. Hi, 

    I kinda figured you were in the Wake area from the pic of the missionary baptist church and one way lane test track video. Awesome build and good to have more zed fanatics in NC!!

    I haven't logged on for a while, but read you build and had to say 'hi & kudos'.

    I own a 73 240z. Finally running/driving, currently tuning. I reside in Wake area, but temporally at Troy NC (also car).

     

     

     

  5. Hello All,

     

    I own a 73 240z. Im having problems getting the rebuilt motor to run. And would like some advice and help.

     

    Motor Specs:

    81 280ZX lower block with standard size flat top pistons, rebuilt.

    73 240z heads cylinder cleaned, rebuilt and valve change. the camshaft is a Schneider 274F. (The head was "decked" bottom resurfaced)

    an E12-92 equiped distributor.

    SU carbs with 73 intake manifold (Unknown yr of SU's).

    header in 6 - 2 outlets(No muffler yet).

    82 280ZX 5 speed transmission.

    Mechanical pump.

     

    The car has been hesitant to start but doesn't. I rebuilt the carbs and found one of the jets was seized. i did change the jets with new ones from Walker rebuild kits. I sized the floats according to the walker guidelines, but once installed no pressure was going into the empty float tank. I resized the floats and tested by blowing throw the fuel inlet for passage and also while installed. I filled the float tank slightly with fuel and installed everything. The float sealed due to the fuel inside the tank. Did the same for the rear carb. I had a difficultly  understanding camshaft timing, then found an hybridz post MSD video that helped. The initial pics are the cam set at 2nd notch with the dash slightly to the left of the groove. Both 1st cylinder lobes pointing in a v pattern at TDC. Upon cranking, motor was hesitant, but didn't start. No starter fluid used. No backfire or smoke from carbs or exhaust. The 2nd pics posted are the same setting, but set to 1st notch with dash slightly to the  left of the groove. A whine upon cranking. Had to use starter fluid. It would bob and backfire on both the header and carbs. Rear carb backfires loads, sometimes spits sparks!! The front carb hesitates when fluid is sprayed and the rear backfires and sometimes out of the front carb.The carbs are turned 2 revolutions down from the  top flush. I drained the float tanks twice and there was fuel inside. 

     

    Now, I need advice and help before I burn this beauty!! Any advice on using schneider 274F cam? how to set cam timing for such cam. Cant upload the videos, Ill try to attach them.
