Blasphemy? Crank triggers.....

[RedMist]

I've been speaking with Link in regards to triggering my "Toyota" VQ35DE 350Z engine with another triggering set.

My problem is that the 350z engine has the crank angle sensor trigger wheel attached to the flexiplate. I'm replacing the flexiplate with a Kennedy flywheel and adaptor plate to my Fortin gearbox.

The easiest thing to do is to transfer the trigger set from the flywheel to the pulley end of the engine. I wondered if there was any modern Toyota engine that is triggered from the pulley end that I could adapt to my "Toyota" 350z?

Beams 3SGE engines have a hall effect CAS counting teeth on the circumference of the crankshaft cambelt pulley.

I can take a picture later on if you like.

[Mr Revhead]

theres a few that have the sensor up front....
most of the new generation engines.
the new yaris etc have the CAS mounted in the end cover "looking" at the crank. yaris CAS is also stupidly cheap due to a recall on them.....

That may be the way to do it. I've discarded the AC unit and all other ancillaries run off a single belt. As such I have a second pulley drive idle. It could be possible to machine out the ridges and cut some groves in the outer of the pulley.
A pic would be lovely.

With the megasquirt ecu's a lot of people used the ford edis setups.
You would need to weld a ring with teeth on it to your crank pulley. and obviously ballance it.

Then you fit a module which counts the teeth and directly controls a pair of waated spark coils.

With the Link its a bit simpler..... the Nissan a bit difficult.....

The Link supports basically any trigger combination you can get. You simply configure the teeth and teeth missing. The reason I wanted Toyota is I trust its reliability and I know Link have already configured the Toyota trigger set with VVTI.

The Nissan being a V6 with two constantly variable intake cams has two cam sensors and still requires a crank trigger.... as the cams are variable. And although I havent looked at it closely yet I've been told (although I'm doubtful) that the ignitors are integrated into the 6 coils. Hence a bit difficult and forcing me to run the Plus G3 in this car and my rally car. In a way I'm glad as I was making compromises in order to cut inputs and outputs on the LEM G3.

The 7A engine I had, had a sensor mounted into the oil pump housing that triggered off the rear of the cambelt drive pulley.

Is that the sort of thing you are thinking of?

just sitting in my garage about to get biffed out if you want some pic's of it,
or want it.

Not exactly what I wanted. But may be more supportable as I can get to the sensor (the engine butts hard up against the cell). Its not going to be as accurate as a crank sensor though is it? The ZE CAS I ran on the race 4age allowed a couple of degrees of timing deflection at the crank. This could have been a coding issue with the LEM4 I was running.

Should work with the G3 Link... I think.

What you could do is fit a toothed wheel to the crank pulley. And instead of using the edis module, use another type of vr sensor and feed the signal directly into the ecu.

when he says cambelt drive pulley, he means the pulley on the crank
thats they type of system i was referring to above.
the yaris/echos had a recall with failed CAS (in the pic i posted above) as such those sensors are about $18rrp...

from my (limited) understanding of the system and the link system all you need to do is mount that sensor so it can read a trigger wheel.....
sounds pretty easy! hardest part would be making/modding a trigger i imagine

Thats what I'm looking at doing. Replacing the trigger wheel on the flexiplate with a trigger wheel on the crank pulley or cam pulley (prefer crank as you dont get slight variations due to belt or chain stretch). Its just a matter of stealing a trigger wheel and VR sensor from a real car "Toyota".... actually Link have played with VVTi before but not the Nissan version of the same. Its easier to keep the triggering something with which they are familiar.

Ahhh lots of noodles!!
Emailed you yesterday re Yaris parts.

Cambelt drive pulley... never heard the crank pulley refered to the cambelt drive pulley... but logical I suppose.

[strx7]

why aren't you playing with a 2GR-FE?

[Mr Revhead]

probably price....

[RedMist]

350z engine, $2150 to my door including loom.

Better yet same bolt pattern as the 3.7 ltr VR engine and probably the new GTR engine.... if I ever need the power.

[RedMist]

probably price....

You calling me a tratorous cheap arse?


..... you know me better than I thought.

does this read the notchs on the flange? (hehehe flange)

[nite b]

Seems, plenty of later toyota engines might have the setup you need. Lexus maybe? Usually pickup on crank and sync up on cam tho.
Running my Beams 3S on a Stink and its been a prick of a thing, runs great but will pick up error counts below 1200rpm and is a b*tch to start. Either fires straight away or not at all. Many calls to ChCh and weve tryed different camdrives (less teeth with different sub boards etc) and still cr*p.
No dramas with Link on all other toyota crank triggered engines though..
Maybe also look at Batman/Cosmo 13B-Turbo engines, pretty sure I saw them with a cool as factory setup with trigger/sync system all in 1, easily adaptable too. If you find a pic, it may be suitable.

Good luck,
Brendan
