i knew that was sus :sick:

bit weird you would have that number :action-smiley-069:

thanks for the correct help tho, though ill believe its the right number when i find out lol

you could always, you know, look yourself. Its result no. 2 in google lol. :)

Just a quick question.

If i get an engine rebuild with all the internals done like pistons head work etc and the stock turbo rebuilt if for some reason i have to go threw regency will they pick up on this at all?

Would they be able to tell whats been done to the motor and turbo seeing as will still look ''stock''?

If you change the cams, they'll be able to notice it by the idle, if not the emissions (if they do an emissions test that is).

Stock turbos rebuilt with steel wheels will be undetectable if theyre in the stock turbo housing however you wont be able to have a boost controller fitted as that is a defectable mod.

Depends on how stock you go - obviously getting new gaskets, seals, springs, forged internals etc are just replacement parts but if they suspect you've worked the engine they can quite easily suggest an emissions test - and lumpy cams are a dead giveaway

I had a rebuilt rb25det and a highflowed gcg turbo. Now the turbo looked brand new as it had been sandblasted, I made sure to remove the GCG logo and just told the guy it was rebuilt to standard specs.

As far as the motor theres no way in hell they are going to know if its got forged pistons or not, I know they couldn't tell with me.

im running cams with a lumpy idle and i didn't have a problem at all when i went through regency

Guess you were lucky then dude... knowing regency, I wouldnt give them the rope to hang me with...

Also, a customer of my mechanics had a very lumpy cam put into his commodore - 3 weeks later he was defected because the police officer suspected modification (due to the idle creep) and sent him down to regency who then told him he could only keep the cams if it passes the emissions test.

No idea if he had the test done as I've heard that emissions tests arent cheap - just think its something to be wary of.

Like Damo said tho, they wont strip ur engine apart to see whats in it, but its really not hard to chuck a gas analyzer on the exhaust and see how its running...

hmm ok but what do u mean by throwing a gas analyzer on the exhaust to see how its running? high emmisions from the cam? :S

well im not a mechanic, but from what i understand, modding the cams changes the efficiency curve, ie it might burn richer at lower rpms but be geared for upper end power...

each car has a certain emissions target due to the standards of the day, and so regency sometimes use this as an excuse

a gas analyzer will not only tell the air fuel ratio but how many hydrocarbons are being generated and what type they are - again I don't know the details but like the others have said, forged internals will be fine - its more cam and ignition timing that changes the efficiency of the engine under certain conditions

this bloke with the v8 was pretty pissed off cause changing cams on his particular engine wasn't anywhere near as easy as doing a DOHC engine like an RB

Regency don't do the emission test themselves so i dont think you really need to worry about it. my car passed and it idles at 1000rpm when it should only be 600rpm or so. If you fit a standard exhaust they wont be able to notice as easily.

Depending on the type of the piston used the dome design might lower/raise compression, it might also change the burn characteristics so that you get different emissions.

Most workshops will dodge something up for you though as they know regency will only check if the values are absurd.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
