  1. Oil pan drawing?

    Does anyone have or know where to find, a drawing for the L28 oil pan bolt pattern?
  2. L28 Crank Angle Sensor Mount and Trigger Wheel

    No problems with mounting the trigger wheel on the non-rigid part of the pulley? Seems it would give an incorrect trigger signal due to vibrations in the rubber mounted part of the pulley. I know a guy that install lot of both MS and Vems systems, and he recommends not to do it that way. Otherwise it seems like a neat solution!
  3. S130 vs S30 at high speeds 100mph+

    With a front airdam and lowered aprox. 2 1/2" and a modified suspension (and around 280+bhp to push it), my 280ZX was stable all the way up to a speed of 249km/h (155,6mph), calculated, not "speedo". I had to break then cause I ran out of straight, but it felt like the car could top out at somewere around 255km/h (159mph) My friends car (280ZX) with no airdam and stock ridehight was getting nervous at around 185-190km/h (115-119mph)
  4. twin turbo

    So getting quicker respons is worthless!? I´ve gone from one turbo to twin on my L28, and though the respons was rather quick on my "single" installation, the twins where noticebly quicker! The best way to feed a turbo (on a 4-stroke engine) is with the exhaust from 3 cylinders with evenly spread ignition sequence (that is 240 degrees apart). You can achive that with (on a 6-cylinder) twin turbos or with one turbo with twin entries. Here´s some pics of my twinturbo-arrangement: http://speedfreak.nu/forums/gallery2.php?g2_itemId=38685 http://speedfreak.nu/forums/gallery2.php?g2_itemId=38678
  5. intake manifold clean up - info

    I've cleaned up my intake and got rid of a lot of bungs and protrusions among other things. Also "cleaned" up the inside of the intake, by cutting the plenum in half and then weld it together whilest widening it a 1/2 inch. Look here for picture's: http://speedfreak.nu/forums/gallery2.php?g2_itemId=38685 http://speedfreak.nu/forums/gallery2.php?g2_itemId=38697 The car is slightly "nervous" from start-up and for a couple of minutes, but then runs really well. I never drive it on the winter though!
  6. Looks to me he has to make new bracket since these seem to be made for a sedan! The wing itself seems to be pointed in the right direction.
  7. L6 supercharging pully idea (pics)

    Yes, you will kill the water pump pretty quick!
  8. You will frown. Guaranteed. McLaren F1 ...

    The text says it's (was) the only car that were driveable after crash test...
  9. Hi from Sweden!

    Welcome! Nice to see more people from Sweden!! Have you visit the site "www.speedfreak.nu"? If not, please do, it's a site dedicated to all Datsun/Nissan Z-car (and some others). I, myself, own both a 240Z and a 280ZX and live in Ornskoldsvik. Tack och hej! (that's in swedish)
  10. I mounted the oilcooler under the IC between the framerails. Had to modify the rails and the parts were the headlight case mounts to the chassi, but I think it was worth it!

  11. Splines?

    Used Z31 parts don't grow on threes in Sweden, and buying new ones ain't that cheep. I had plans for doing a completely custom made axle with 35mm bearings and beefier splines, but than I will be forced to make a custom made joint for the CV-axle, and time is somewhat short...
  12. Splines?

    "Zhadman" It's only a centering device for the brake disc, and it is that thin to save weight... "zcarnut" The Z31 pattern is 5x4,5" (5x114,3), and BMW is 5x120mm (5x4,72"), so they are not interchangeable. This is taking some time, but the cost is almost nothing. I will be running 8x17" wheels up front with 312x20mm brake discs, and 9,75x17" wheels at the back with 300x10mm discs
  13. Splines?

    These stubs I´m making will cost me nothing, so I think it´s worth it! I guess I just have to send the old ones with the drawing and let them make the new splines from the old ones. BTW, here are some pics from the front hub and a drawing of the rear ones. http://speedfreak.nu/modules.php?set_albumName=album436&id=Nav&op=modload&name=gallery&file=index&include=view_photo.php http://speedfreak.nu/modules.php?set_albumName=album436&id=108_0833&op=modload&name=gallery&file=index&include=view_photo.php
  14. Splines?

    Pictures and someone telling me how many splines there is gives me nothing... I need to know the module and/or as many measures as possible of the toots. I searched through all (I think) the posts on "splines", and came up with nothing! I´ll send a message to Scotty and Tim to see if they know, or maybe Ross C has the answer!?
