  1. Awesome looking car dridge! Nice neighborhood too! ;-) I guess I will need to change my login picture and signature if I am going to hang around here! Hope the Z treats you well!
  2. Royce,

    Long time man. I've been under a rock for the past few years.. getting back into cars again. I jumped from cars as a hobby and made it my job. I now work for RUF Auto Centre in Dallas Texas ( www.racperformance.com )and we were talking about the Lotus Cortina. Made me think of you giving me that ride in one out at Infineon. Sill got em?

  3. Mitchka, I don't think you can do much better than validation from Bruce at Ztherapy! I'm sure he has seen many of the manifolds and had the chance to inspect them from different angles. Thanks for the good info Bruce. The only thing I would like to add is just that neither of your 260Z's would have come into the US new with round top SU style carbs nor an E series intake manifold (E46 or E88). I would assume that on your early 260 car someone just swapped the carbs and on your later car someone swapped both the carbs and the intake manifold. One advantage to the earlier style E46 intake
  4. From zhome.com, Documents, Index Of Technical Articles, How To Determine what ratio a specific differential contains. "The Following is a note related to an easy method of determining which rear end gear ratio any Z differential is - before you take it out of the car, or install it in your Z. Sent to the IZCC's "Z Car List" by: Ross Corrigan, IZCC #255 -------------------------------------------------------------------------------- Want to know what gear ratio that Z rear end is, before you remove it from the car or install it in your Z? Take a buddy, and just turn it to find out. My dad and
  5. Nissanman, Good call. You guessed correct. I did measure the rotor hat from the outside starting at the rotor surface and not from the inside which would include the rotor surface. Thanks to you and Stephen for the information. I was just on MotorSport auto web site and it "seems" that the wheel bearings and seals are the same from '70 240 - '83 280ZX. So that seems to support my theory that the 240 hat/rotor combination might be able to be swapped with the later 260 hat/rotor combination. I tried to confirm on the Courtesy Nissan site, but they do not list the wheel bearings. I may hav
  6. Howdy folks, I have a 09/71 built 240Z ('71 model). I just received new rotors but they don't fit. The "hat" height is different. I used a tape measure and got the following measurements. The new rotors have a hat height of ~1.25". The old rotors have a hat height of ~1.5". I did have some old rotors around from a parts car that look like they match the new rotors. In fact on the spares it looks like the hub is thicker and the rotor hat is more narrow. So the net result looks the same, using eyeball only. I am sure they came from a first generation Z but not sure what year or 240, 260
  7. jimmypleitez, You may have relized that posting was from several years ago. Sorry, I don't know if the cars are still around or even have the guys contact info. I don't have any parts for 280Z fuel injection system either. Hope you find what you need. Happy Holidays! Royce *<| : -)
  8. That car looks familiar! Didn't Zmefly have it in his avaitar at one time. Maybe he knows something about it to!
  9. I have some old ones that I would like to replace and have not been able to find the same quality these days. I like them with one of the hooks right on the ratchet and about 3" wide and about 6' in lenght. I got some at either Jegs, Summit Racing, Racer Wholesale, or Pegasus. But they just don't work as nice as the old ones I have. The newer once have flimsy straps that bind in the ratchet. Also, the ratchet action just isn't as good. You may want to try those places to find what you need. They all can be found on-line. If anyone finds some they consider good quality let me know. Than
  10. Howdy, I am sure a good cold air induction system would help a little. I think it is somewhat of a scam with how heavily they are marketed these days. But for a track or race car I am sure they help a bit. Scott B., former owner of Ztherapy, used to make a custom airhorns and a airbox for the 240Z SU style carbs. But it wasn't cheap, something like $400. It looked good with about a 3" round inlet so you could easily plum to the front. I think he opened up one of the holes in the radiator support and ran a cone type filter like K & N. I have also seen someone show a picture on the web
  11. Compression tests and leak down tests are best done with the engine warmed up to operating temperature. If the engine is not in a car and cannot be started it is very hard to tell what you are getting. I would ask who rebuilt it and ask for receipts. If they cannot produce an engine builder and receipts for the valve job, vavle seats, rings, bearing, machine work, etc. then you might as well flip a coin. At that point it is a gamble at best! You might end up with a great deal on a rebuilt motor or spending money for a fancy looking chunk of metal! If it is on an engine stand you could lo
  12. One thing I didn't really touch on is the external differences between the diffs. Remember the diff assembly has many pieces. There is the diff carrier which is generally what you see on the outside. Then on the inside you have the ring and pinion gears and all the bearings and other bits. The interior and exterior of the R180 and R200 are different. The R180 diff assembly is physically smaller and lighter than a R200 assembly. The big difference, as far as compatability is concerned is that they require a different rear suspension member on '70 and '71 model 240Z's. The early 240Z's had
  13. Here I go again with the fancy Z ratio tool again. I added this to the links on this site under "Z car transmission calculator" See http://www.geocities.com/z_design_studio/ and you can graphically compare different preset Z trans, diff ratio, and tire combinations. So you can see what the difference really is in terms of top speed or revs and any MPH or vis-a-versa. It is very cool and I used it a lot when comparing different parts I found for my car. The key to gear ratios is that in performance situations you want to "have the engine where you want it!" That means so that you are not wa
  14. Actually, "over restored" cars is much an issue with all makes. If you watch the restoration shows on SpeedTV they are always talking about the need to match the factory overspray on the undersides and door jams of classic cars- like Corvette's, Mustang's and Mopar's. I am sure the same is true fo the European restoration. In fact, I was at a very high end Italian car restoration shop in Berkeley, CA. I was commenting on a beautiful '50s Maserati OSCA MT4 that was still on the shops transporter. The shop owner said how it was such a shame that the owner paid more than half a million dollar
  15. Oops! Rewind... ment to say the car had never been "repainted". I mean, the paint was original. Oh, it's not a DeLorean! Good catch Mr Camouflage! Too funny!
