  1. OEM re-worked castings, with added sensor ports, they are just as tidy inside too
  2. Adjusted the throttle position sensor, that fixed it
  3. I have fitted a new inlet manifold, Nology leads and wired in the AEM AIT and MAP sensors. However, the overdrive light is now flashing periodically, and overdrive does not fully engage. Does anyone know what have I done to cause this?
  4. :search:Still looking:search:
  5. I will have the oil temp and pressure gauges please
  6. For a moment, I thought there was a glimmer of interest in my project, and have spent the last couple of hours trying to resize photographs to post for your interest. Like most on here, I am a Supra enthusiast. Unlike some on here, I have no interest in Supra politics.
  7. I have not been ignoring your posts, just unaware of any activity. Should you have read the whole thread.......... I am aiming for 280bhp, to allow for the average of 20 that will have escaped during the 60k it has been driven. Contrary to popular opinion, I believe 100 hp per litre is acheivable from this engine without spending a fortune. To upgrade the cams would give me hp, but at the expense of economy, so far my focus has been on efficiency, which gives me better mpg when not having fun with the bhp. I am giving the stock cams a go first with the Unorthodox Racing adjustable gears. U.R. claim a gain of 10, but a U.S. magazine made a proven 22bhp gain, but don't know what other mods the engines may have had. Further to the list in my signature, I have taper reamed a throttle body, gas flowed an inlet manifold, fitted it with AEM temp and MAP sensors and have a set of Nology Hot Wires ready to go on next whilst reshimming the tappets. Waiting for the HKS Twin Power, the plug and play loom, and fittings to install the Fuelab regulator. When these bits are fitted, I have some more work to do with insulation and ventilation, then I will be ready to fit the AEM ECU and take her to Silverstone for a trundle on the rollers. Whatever the outcome, I am enjoying tinkering with my Supra, will try and post some snaps.
  8. I will have the TRD oil cap if it is not sold please
  9. These lovely cars are worth more sold as parts. Sad but true.
  10. :search:Still looking:search:
  11. No pm in my box Have another go ?
  12. Active spoiler?............ First dibs if it has
  13. If not sold, I will have the brake lines please.
  14. Looking for an active spoiler, with switch and relay please.
  15. Please be patient, I can't work any faster I have loads of pieces nearly ready to go on, next week I hope, when I find the opportunity and it's not raining Busy working on an inlet manifold, (waiting delivery of sensors) cutting back the lips (done) sound insulating rear quarter panels, (done) modifying suspension (done) ready for the wheels (being re-faced) (need painting) and tyres (waiting delivery) to go on too I am busy, and as I said, the bits will be listed as they go on. Both the induction and exhaust systems are one off's to my spec, I pay great attention to detail of each component, the exhaust system for example. It is proven that for an N/A Supra, 2 ½” is best for torque and 3” is best for horse power, with 2 ¾” being the usual compromise. Ideally you need 2 1/2" for low revs and cruise, and 3" for the track. So I have designed and built a system that lets you have your cake and eat it too! Autobahn88 exhaust manifold, thermal wrapped. Blitz 3" midpipe, thermal wrapped. 3" H.K.S. cat back exhaust system. Magnaflow 200 core racing cat immediately after flange. Wideband sensor fitted into front of cat. 2 X Morosso 94501 spiral racing mufflers, 1 immediately after cat, and the other just before the back box. (1 would be sufficient for most, but I drive long distances and wanted peace and quiet on cruise) Apexi Integration 155-A025 spring loaded tail silencer at back. The manifold, midpipe, cat, spiral mufflers and back box are all 3" bore for horse power, utilizing the spring loaded tail pipe to restrict gasses at low revs and cruise giving torque, which under load opens up and lets the horses out. These components had to come from 'somewhere', so it is understandable that some are T.T. items. Both induction and exhaust systems have given significant power gains, and I continue to develop other components to further improve the induction. Sounds good too
