    My Swiss 1972 S30 240Z rebuild project

    Wow, this is crazy! Just scanned thru your thread. You've been at this for what, seven years or so? Very cool, keep it up!!!!

    38's aren't going to cut it for what you want. Look at U20 engine specs that uses 46 SU's, 9.5 compression, 1.75 intake ports, 1.75 in valves, 1.38 ex valves, plus a large bore to allow it to breath. That last part, a large bore, The U20 had a 87+mm bore stock.

    For $5k u probably could do a KA swap and get a very reliable runner stock. If L is your route, gotta use 46mm SU's and poor all the money into the head, porting, welding the combustion chambers, larger valves, cam, valve train, etc., need a good honest 10.0 to 1 compression but the KA would probably still be faster.

    610 street demon resurection

    That master cyl, isn't going to fit unless you ditch your booster or drill holes in the strut tower for the bleeders, just another thing to deal with! Keep at it!

    My Home Built Rear Coilovers

    What a steal! $39 to my door. Chinas best! Springs are to short & to hard. Figure about 425 in/lbs. The threaded pcs just fit over the front strut tube though, so I'll hold them up with split collars. Then I'll be able to use the threaded part to set corner weights, a lot easier than trying to move the split collar a skosh. Might use two springs in tandem, that would bring the rate down to about 210 in/lbs while keeping a fare amount of wheel travel. Rule of thumb for spring length is the springs need to be about 2 X the shock travel.

    Olde Skool 610

    Success! Put on about 40 miles yesterday. Probably more miles then its seen in the last 5 years. It was hot (90's) water never got above 205. That was after a lot of spirited driving (3500 to 5500) and a couple good pulls to 6000~6500. Thinking of painting the center of the wheels satin black? Got to find some center caps as well. The tires (205/50-15) are just a tick taller then the 205/60-13s.

    Holy crap! Its been over 2 years since Ive added anything here! And its pretty much been over 2 years since this car has been on the road, and it still isn't. Tomorrow, we shall see. New shoes, out with old and in with the new. Of course just cant post a picture in here without knowing the secret hand shake. Some things never change. https://imgur.com/xwa8SEh

    Anybody tried a DGAV?

    Get a manual choke conversion kit, like $15.

    Anybody tried a DGAV?

    FWIW, early Capri's and Pintos used water chokes. As far as parts go, Pierce Manifolds is the place.

    L20B intake/exhaust gasket... help!

    Stoff, According to the Remflex website, I believe they crush to half their original thickness.

    L20B intake/exhaust gasket... help!

    One other source that might work is Remflex. They produce solid graphite gaskets that crush, they will also do custom stuff. http://catalog.remflex.com/NISSAN_Header_Exhaust_Manifold_Gasket_p/15-001.htm

    L20B intake/exhaust gasket... help!

    I believe distrutorguy is looking for a gasket that actually seals the 2,3 exhaust ports from each other, he's racing. Most of the manifold gaskets that are out there for 4 cyl L engines, do not seal the 2,3 exhaust ports from each other. Street motor, who cares, racing, different story, especially land speed record sht. What stoff suggested, that gasket cut up, would seal the 2,3 exhaust ports from each other. Just my 5 cents, inflation!

    I believe its Top End Performance? There listed on Ebay. Maybe not? https://www.ebay.com/itm/Datsun-510-Exhaust-Header-GASKET-For-L16-L18-L20-510-and-Pickup-/312184834731?_trksid=p2385738.m4383.l4275.c10
  15. UTQG ratings are typically required for manufactured tires of over 2000 units or more per year. No UTQG rating is the same as a UTQG temperature rating of 'C'. Traction and tread wear ratings are a manufacturer supplied number, nothing else. Temperature rating on the other hand, determines the severity of a DOT required test. An 'A' temperature rated tire undergoes a more severe test than a 'B' rated tire, and then 'C 'in terms of severity. Other determining factors of DOT testing are of course tire size, load index number and load rating IE 'extra load', 'standard load' or 'light load'. Any speed rating on a tire 'S', 'H', 'V' and so on are manufacturer supplied ratings, like traction and tread wear, and do not require any DOT tests to actually verify the rating.
