Distributorless 2jz-ge -Need guidance on cam sensors other than the TT cam sensor mod

[rx22nv]

Hi guys,

Been collecting parts for my 2jz-ge NA-t conversion for a while and am about to start putting it together. I have the TT oil pump and lower pulley. I need to sort out what to do about a cam sensor.

I don't want to use a 7m CPS, or cut down the original dizzy as I will be changing cams at a later date. I also don't want to run the TT Crank sensor only as I wish to run full sequential injection.

Anyone know of a solution? I have seen people welding bungs in the side of the head for the TT cam sensor but I'm not capable of this myself and I don't know if any shops in Australia would know much about it. I have also seen heads warped from this method.

I have searched but couldn't quite find what I'm looking for. I have seen a picture with a cam gear and rare earth magnets but that's all they were - pictures!

Any assistance, advice or a previous thread would be great.

Daniel

I'm in Brisbane and the engine shop where I work would be able to add the sensor bungs for you if you really wanted to pay what the job is worth. And btw its not hard to straighten warped heads. I do it all day.

another option is putting magnets on 1 of the cam sprockets and attach a hall sensor to the metal shroud behind them...I believe daveh did this mod, theres a thread somewhere on here with more info on it...no need for a tt cam if going this route

That is probably what I'm after most. Something portable that can be swapped between motors should a blow up happen.

I have a set-up that might interest you. i use me stock dizzy as my cam/crank signal and run a 2jzgte ignitor coil packs and runs waste spark through my Aem. been a few years since i have had mine fired up, but let me know if this interests you.

Thanks for the reply. Only trouble with that is that I plan to run different cams so want to get away from the cam driven dizzy or the mk3 cps.

on my 2jz-gte i run haltech hall trigger with their trigger wheel, its really easy to mount and wire, so this might be an options for you. other than trigger/magnet and hall sensors your pritty much left with (if you dont want to use 7m CPS or stock dizzy as CPS) welding a bung like other has said. as far as wat I can come up with now, these are your only possibilitys.

[rx22nv]

Can you tell me more about the haltech trigger wheel? Is it a crank angle sensor only?
I live about 20 mins away from Haltech head office in Australia.

if you have gone that far I would almost say get a used GTE Head on the cheap and source some GTE Intake parts and you will be able to run OEM Management with a few wiring mods. I used to run a hall effect Crank Trigger setup with Accel DFI & FFIM on my NA-T before I swapped over and I am much happier now.

[rx22nv]

The only trouble is that in Australia and TT heads are not cheap or widely available. It would make things so much easier I do realise.

I'm going to be pushing it fairly hard so If i have a blow up, I'd prefer replacing a $500 NA engine that uses more expensive bolt ons, rather than a $3000 TT engine.

I have found someone who can modify me a cam gear with magnets, just have to see if it will work with a haltech or a microtech.

there is nothing wrong with the haltech hall trigger. is dead easy to install and pritty reliable. though you need to install it right, else it has a tendency to fire on the wrong spots

[rx22nv]

Have you got the one that uses the magnet or the one that picks up on metal?

[hybelkaninen]

on my GTE I run motec m800 with a regular magnetc trigger (its a custom harness, sensors and triggers) . but hall effect works basicly the same way, hall uses a trigger wheel with notches, sort of like a sproket with one missing tooth. you could just run a magnet on either the harmonic balancer or one of the cam gears. though placing the magnet on the cams is a pain especially if there is variable cam gears on your engine. if i where you id run a trigger wheel mounted on the back of one cam and a hall effect sensor (this wont be effected if you run variable cam gears since it's mounted on the cam itself and not the gears) and call it a day. easy and simple if you have management able to use it.

how would this mod run on a NA (non-turbo-ed) engine??

you wont be able to keep the stock ecu if you want to run a trigger. these are made for standalone ECU's that can utillise hall/magnet triggers. If you have an ECU that handles these triggers, it doesn't matter what kind of engine you got. BTW this ain't a mod you can do to make it produce more HP, its trigger systems for the ECU to know when to fire, just like the CPS in your stock GE dizzy ;-)

cheap solution.... 7mgte wiring harness,ecu and cps...

This is what I will be doing

Hey I'm looking into this method as I am having clearance issues , except I run a pro efi. Can you elaborate a little more on this set up? Larry from sp mentioned something like this to me over the phone but I kinda brushed it off as he mentioned the expensive pro efi smart coils.

bumpity bump for an old thread.

Do you have more info on this? I can't gind anything on the forum or on Google.

Use the 2jzge distributor with no cap or rotor for your cams and crank sensors sensors get a 97 sc300 oil pump which has the crank sensor provisions with the 96+ crank timing gear if you want to. My 97 sc300 has a crank sensor on it.

[rx22nv]

Using the dizzy would be easy and perfect but it won't allow you to change to TT cams.

Using the oil pump and crank sensor only is also good but the computer won't know which stroke it's on. The cam spins once for every 2 rotations of the crank.

I think It's probably the most cost effective to weld the sensor in the head.

[jwinproductions]

Schneider cams make regrinds for 2jzge motor. Tell them what you want and they will make it for you. TTC makes cams for 2jzge as well. I think to go through all that trouble to run TT cams.
