TOYOTA SUPRA V6 biturbo
- 6 cyl , 2.5 L
- 2 turbocharger
- low impedance injectors
- VR primary trigger
- stock 12 toothed crankwheel
Dangerous idea
My idea is that to remove 1 tooth (black circle), so we'll have a 12-1 toothwheel. You can see here the picture of the wheel at TDC position.
What do you think, will it work good? We have only this one wheel, no room for mistake.
There is some risk of an abnormally high amplitude VR signal at the missing tooth. Scope (or soundcard) recording of this trigger is definitely a good idea.
Camsync 1 pulse is available (otherwise an M8 screw would do it, used with GT101 HALL sensor, see sensors in WebShop), see InputTrigger/MultiToothNoneMissing and treat it as 24 + 1 setup (as if 24 was on cam; but 12 on crank is better timing precision, of course, because no cambelt sloppniness).
Q: MembersPage/PhatBob what model of Supra is this from? All the Toyotas I've seen have a 12 tooth per crank revolution and one or two cam sync's. I have a fair bit of toyota info so if you could give me the engine number I'll see what I can find
A: 1JZGTE engine. It has two cam sync.
- You should be able to use these triggers without modifying the crank trigger as this is, believe it or not, the same trigger pattern as you find on the Honda, Mazda RX7 and other Toyotas. With this trigger and cam sync you should be able to run semi-sequential and wasted spark very easily.
