V8ZRACER260Z

I had to do some trial & error on this. Somebody else probably has a chart. I went to the dealer and changed out gears till I got close. Mine is still a couple % off but good enough for street driving. Another sugestion would be to get a electronic speedo from Autometer(only avail in 160mph) and set it by the touch of a button, This is what I would reccomend. I opted for the 200mph speedo which is only avail in a manual config. RICK

I agree on the 3.45 R200. This is what I run in my Z. Trust me you don't need a 4.11 with the V-8. Z's are light cars and do not need a short gear to get them moving ask Scottie he has a 3.07 running 10's! My Z with a 83 T-5 turns about 2700 rpm @ 80mph on the freeway. Rick

Just a diferent idea on my guages I dissasembled the factory guages and used the original bezels. I super glued the small ones back to their original locations (note use professional grade superglue!). This allows you to insert the guage from the front and use the included hardware from the back. This way they are adjustible & removeable if necessary. I also install mechanical guages but utilized the factory plugs to wire up the guages(remove the end off the factory guage leaving as much wire as possible, use solder & heatshrink on all conections to minimize problems later). This way if I do need to remove one I just un plug the guage from the factory harness. The spedo & tach bezels needed modification to fit the Autometer Guages. This can only be done by removing the dash, this is not as difficult as it seems. Plan on spending a good weekend to finish this task. I have had mine in for over a year now with no problems. I will post photos next time I have the dash out. I used the Phantom Guages which look very trick with the white background and the red pointers.RICK

Your cooling system pressurizes when the engine is running. If you fill it up when it is cold as the coolant heats up it expands and with out an over flow there is no where for the coolant to go but out of the system. Eventually you will loose enough to cause over heating, Not to mention leaking toxic antifreeze on the ground. Overflow bottle are easily availible and are required to maintain an effective cooling system. You may also want to do a pressure test on your system to check for any leaks or bleed down indicating a leak you can't see (such as a heater coreor internal leak in the engine) also be sure to pressure test your cap the rating should be on the cap itself.
