Hi, Im writing on behalf of a friend who owns an 89' MA70 7MGTE supra. The car was purchased about 2.5 a half years ago with a number of pre-existing problems. Since the purchase of the the clutch, timing belt, steering rack, centre bearing and a heap of vacuum hosing has had to have been...

I'm almost certain that the TPS is out of calibration because grounding the IDLE pin gets rid of the error 51, instead throwing an error 41. The idle problem is very strange. Sometimes the engine will run perfectly while others the idle will cause the car to stall when standing still. Are there...

Hi guys, Im writing this on behalf of my mate who owns an 89' MA70 and has recently been having troubles with his battery going flat after a couple of days or so. He original purchased the car with an old battery installed and began having issues with it draining. We assumed that the battery...

no one knows or has the correct wiring diagram?

If someone can help me out with the + 12v parking light wire in the drivers junction box I'll be sweet. I've successfully got the remote start, alarm and remote central locking working but I'm waiting on a multimeter probe to test for the parking light wire. I can't seem to find the correct...

Think I may have worked it all out. Might write up a guide once its all installed and working

Well i made a couple of posts on supramania and had a look around but i didn't find all that much stuff. Has anybody installed a Viper alarm and remote start in their MKIII that I could possibly ask a few questions please? Just can't seem to find the right info for the Viper.

Thanks guys... I'll have a good look at it and I'll let you know if i manage to find them.

Yeah thats what I was using but they're all US. For instance I can't seem to find the correct door trigger and parking light wires in my supra. The wires just aren't there or are different colours. I think i might just have to get the multimeter out and test for everything. Makes a lot more...

Hi Guys, Started to install an alarm in my mates 89' MKIII but i have come across a major problem in that the US wiring diagrams seem to be different to the Japanese model. Has anybody installed an alarm in a JDM model or know where I would be able to get the wiring diagrams from? Cheers Toby

Hi guys, my mate owns a 89' 7M-GTE MKIII Supra - Japanese Import and we have decided to install an alarm in it. We've both have a reasonable understanding of electronics and began tackling it a day ago. However I have run into a bit of a problem. All of the wiring colours I have found on the...

Hi guys, just interested to know about the best way to tune an MKIII with the e-manage. I'm fairly new to cars but am keen to get into it. I've done a fair bit of research into fuel mapping and stuff like that but i wanna know more detail. The main reason is that currently my MKIII is having...

ok, so if we look at in terms of an air compressor. If i were to attach a nozzle to the end of the the guage pipe would the air coming out the end be at the same pressure as the guage or would the restrictive nozzle change the pressure?

EDIT: I think it may have something to do with the ideal gas law. Can anybody confirm this? Cheers

hmmm, slightly confused, and I've even studied fluid mechanics at uni. Only just passed though ---------- Post added at 11:28 PM ---------- Previous post was at 11:14 PM ---------- Apparently at low mach numbers bernoulli principle also applies to compressible flows such as air. Anyone got any...
