if your t04e is a divided, twin scroll T4 turbo, no changes are necessary.

otherwise, to properly use a t04Z, you will need a divided twin scroll t4 manifold. dual wastegates are best. it might make more sense to use a different turbo however

Depends what type of T04z, Garrett or HKS and the rear housing etc.

I dont think the dimensions of either are the same as a T04e

Although, i dont see how dual wastegates are better than a single if you properly design it all and the manifold is correctly made

Technically speaking Geoff is right , a propper "TO4E" turbo uses a T4 turbine and T4 turbine housing . For the record so does the TO4Z turbocharger which has the TO4 "P" trim turbine and any T4 turbine housing profiled for the P trim turbine wheel . If you had a TO4E with the P trim turbine its housing would interchange with a TO4Z turbo/cartridge .

Where TO4E turbo's got confusing is that small shaft TO4 and T3/TB31/TA34 turbines all use the same basic shaft dimensions and so the T3 etc/TO4E hybrids grew out of interchangeability . Mind you just because they fit together doesn't mean they work very well , sell yes , work maybe .

TO4 P trim type turbine housings are availabe in single and dual entry T3 , T4 and T4 International stud/flange pattern . HKS's unique housings are large T4 twin entry (though open to single entry not far inside) housings with a particular V band size . Garrett makes TO4 housings in a variety of outlet styles including four bolt , six bolt , V band and slip ring type .

Basically what the feller that started this needs to ask himself is do I need a 700 odd Hp capable turbocharger or would a 500 Hp one do the job required , that's the real issue here .

Cheers A .

thanks guys for the replies

the turbo I was thinking of is the garrett t04z (not sure about proper rear housing for my application though)

do I need a 700 odd Hp capable turbocharger or would a 500 Hp one do the job required

the 500 HP will do

    • 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.
