Hello there,

I'm about to buy a T04R turbo kit, but the turbo probably need new bearings.

I see on garrett's website that they've got this CHRA upgrade:

So does this mean I can send the T04R turbo to them and basically have a T04Z come back to me? Although with the same turbine and compressor housings?

Thanks and sorry if this been asked before :(

Correct the T04R and T04Z use the same wheels so the turbine and compressor housings interchange . Actually from memory HKS had the turbine blades slightly cropped in their spec Garrett cartridges but that's not of any real consequence . Other than that the only difference overall would possibly be the turbine housing if its a HKS special .

The complete HKS T04Z uses different housings and would be the pick given a choice .

Thanks...been reading lots of your informative posts too :P

Do you know the major differences between HKS T04R and T04Z housings? Is it those cool looking anti-surge little holes?

Does a CHRA upgrade mean new turbine and comp wheels as well?

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • 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?
