  1. Loren, is there any test for an iacv? Resistance etc???
  2. Thanks Loren. Was hoping if anyone knew it would be you! Thanks anyway for your help.
  3. Does anyone know what the idle valve frequency should be in herz?
  4. thanks guys thats really given me some food for thought!
  5. Hi I've a Boxster track car with a 5 speed transmission. I'm thinking of upgrading it to a 6 speed from a Boxster S. Does anyone have any comments on any disadvantages. Are there any appreciable weight dfferences / installation issues? Cheers Marcus
  6. Hi there I've recently swapped to a coil over setup. Stupidly, I didn’t take any stock measurements on the standard setup before I fitted the new suspension. I've researched a range of settings which go from minus 10mm for use on bumpy roads to a drop of -30mm for race / trackday setups. I believe the new Spyder is dropped 20mm. However I don’t have a base measurement to go from. I don’t like the way Porsche quotes the ride heights from an underbody point as it doesn’t take into account any variance in wheel / tyres diameters, and is also a complete pig to measure. Can anyone get a tap
  7. Hi Does anyone know what the bump/rebound damper rates are for the GT3 Mk2 front bilstein insert / damper? Thanks Marcus
  8. Hi some technical info is needed here... Obviously the drive comes out in a different direction in the 996 box to that of the Boxster. In other transaxles there is often an option to reverse the Crown Wheel and pinion positions to switch the drive direction. Has anyone stripped a 996 C2 gearbox or that of a Boxster to see if this is posible ???
  9. Hi Does anyone know if 996 GT3 Cup doors will fit a standard 996? There's a pair on eBay: GT3 Cup Doors - Boxster GT3 Its going to be used for track days so not too worried about the lack of....etc. Thanks Peter
  10. If you mean are the ignition coils actually step-up "transformers" then the answer is yes. But externally the 12 volt battery voltage is "amplified" via a DC to DC inverter to ~300 volts and that is used as the coil primary "switched" voltage. 12 volts to ~300 volts to ~25,000 volts. Thats great thanks for the info. Marcus
  11. Can anyone tell me if coils on a 2002 3.6 Carrera are internally or externally amplified? thanks Marcus
  12. Hi Does anyone know what the is the position of the crank sensor relative to engine top dead centre. It should always be before TDC. It can be anywhere in 360 degrees of crank rotation. I need this position to setup an aftermarket ignition system. Also does anyone know if its a Hall Effect or Magnetic / VR type sensor? Thanks for any information. Marcus
  13. Thanks Todd. I've retimed the valve lift actuation, and its a fair bit better but I'm missing out on a lot this engine can offer. I think I may be tempted to follow you down the Bosch 7.8DME and canbus conversion route. I dont think I'm going to be able to get the all round driveability & torque band out of the engine without spending vast time mapping & remapping all the various controller permutations. Have you uncovered any articles on swapping to 7.8DME from 5.2.2. My limited knowledge led me to believe I need an eGas throttle pedal & throttle body, and canbus wiring fr
