Hey man, awesome bit of info you have there. Just wondering if I can take your method and do it in a 2005 rodao? (2wd)For those trying to fit a vz 3.6 into a rodeo and cant find any info on it and actually get it running but the engine light is on and its in limp mode (limp mode wont rev over 4000 rpm)and have been told its impossible due to ecu not reading and sensor this and sensor that and the looms are different yada yada yada..
Im here to tell you it can be doneusing the rodeo cps and original wiring loom,I have a 2008 2wd rodeo with a 2005 vz 3.6 engine now running perfect..
So Heres the problem,Your rodeo 3.6 alloytec has only 1 CPS (Cam Position Sensor) on the front of the left hand side head and the vz 3.6 engine has 4,,This is because the vz ecu reads the 1st head (BANK A) as having 3 cylinders which is why they have 2 CPS,,3 per side (BANK A & BANK B)
Where the rodeo has one CPS on the left which reads 6 cylinders hence the reason people say theyre incompatible due to wiring loom being totally different,,which is partly true.
But if youve stumbled apon this writeup then your f...ing sorted cause theyre aint any info on the net for this conversion,,TRUST ME IVE LOOKED EVERYWHERE lol
SO ARE YOU READY FOR THE SOLUTION ARE YA WELL WELL HUH LOL
The solution is you need to swap the rodeos reluctor onto the vz engine,,sounds easy ay lol..Well its pretty simple really,,
Now in a perfect world these would just bolt rite on,,WRONG this uctually would be an easy fix but holden decided to change everything so it didnt suit,sprockets chains bolts,every damn f...ing thing is different,so heres what you do..
Undo the bolt on the cam on the rodeo,Gently pry off the reluctor which is on the front sprocket of the cam,,it does come off but be gentle as you
dont want to damage it. http://forums.justcommodores.com.au/images/attach/jpg.gif
Now find a 3mm thick plate and trace around the rodeos reluctor,,
On the vz engine take out the cps and remove the cam bolt,,dont even attempt to remove that skinny looking reluctor on the vz sprocket,,we tried and im pretty certian it doesnt come off.
Now put your new reluctor in front of the vz one with the vz cam bolt and tighten it up,,
But not all the way as you need to set tdc(Top Dead Centre,,it should look like this http://forums.justcommodores.com.au/images/attach/jpg.gif
Now go to the rodeo engine and find tdc,,now go to the vz engine and do the same,,once done line up the new reluctor (which is now in front of the vz one) relavent to where tdc is on the rodeo engine..
Tighten it up,,Now With a dye grinder you need to very carefully grind the old relucter through the gaps of the new one(which is now the new 3mm front plate) so it matches the new reluctor,,
If you dont do this the cps will read the old one as well as the new one and send all sorts of weird signals,,and make sure you cover every open area to ensure no metal shavings enter the engine or you mite as well give up now and buy a hilux lol..
Once your done with the grinding you need to put a rubber seal/ring on your cps to step it out compensating for the 3mm difference and also to stop any oil leaking out,,if not done when the cam turns the new relucter will smash your cps and probably damage your new relucter..And youll be pissed if youve come this far.
When youve finished that as long as you have done the plate and the timing relativly correct it should fire up with no problems.
If it the timings a little out dont worry as the ecu will compensate if it needs retarding or advancing..
And there you have it..No engine light faults anymore
