Does anyone know what type of speed sensor is in the 5sp supra gearbox? i.e. is it a pulse width modulated one or a analogue signal? Where can you get these from?
jut found the mark IV supra manual online and it uses a pulse width type speed sensor which is bugger as we're after a sinewave frequency modulated one so time to drag out the old electronics textbook to design a ciruit.
what will it be used for? also i thought MKIV came wit that six speed box, and the MKIII came wit the five speed?
it's a supra gearbox bolted up to a 1990 ZR1 Corvette engine in a LX Torana. We keep getting a speed sensor fault which shuts it out of 400HP mode so can only hobble around in 250HP mode at the moment. This car is a weapon at 450HP and the car weights 1150Kg with max torque at 22000rpm and it revs up to 8000rpm It still easily spins the wheels in 4th gear.
Hey Chewy, yummmmmmmmm >>>> Is that motor the LT-5 DOHC alloy 5.7litre??? As I understand it all ZR-1's came with the LT-5 motor - and the ZR-1 option nearly doubled the price of the car.If it is, I'm guessing there ain't too many of them here in Oz. All I can say is NICE![image]http://www.zr1.net/gifs/lt5_blowup.gif[/image]
Mikey, yep that's the one >> Quad Cam All Alloy 5.7L V8 LT-5. It's the first of the test production engines to roll off the line too (were 25 test dedicated engines prior to this one) so it's done a total of 37.0Km in the last 13 years . It has two throttle butterflies in the plenum that open up until 3000rpm when the 8 other secondary butterflies open up which are located inside the heads. The engine itself cost $20,000 and then there's the custom headers and exhaust system that cost $6000. All up I think my friend spent 10 years and $70,000 on this LX Torana of which I've helped for the last 6 years.There was one black ZR-1 for sale here last year that went for $120,000 and that's on a 12 year old car.
