I'm pretty sure most T04's are externally gated, this means it wont bolt onto your existing exhaust manifold. You will need a new one which will take an external wastegate, or you can do what I did, had the external wastegate welded onto the exhaust housing, do a search on "td06 stage" in this thread and you might find some photo's of it, if you want photo's pm me your email and I will send them on. Next you will need new oil and water lines (I'm not sure if the T04 is water cooled, correct me if I am wrong) if it doesnt need a water line you will need to have the existing water line plugged up. Next you will probably come across some sort of boost/fuel cut as the stock ecu doesnt like much over 12psi of boost. Following this you will start to lean out at the top end as your stock fuel pump cant cope with the demand of the bigger turbo requiring more fuel. Next your stock clutch will start to slip and then die because it cant handle the extra power. Have I missed anything guys??? Fitting a bigger turbo isnt just a simple case of swapping them over it requires a lot of systems to be upgraded prior... oh I just remembered do you have a bigger intercooler? you'll need a fmic to help stop detonation.

Is her car completely stock? Geez... she started at the wrong end :) If your car is stock, I'd either sell the turbo and get an exhaust (the absolute first thing you do on any car to increase HP is change the exhaust) or put the turbo on a shelf and do a lot of other things first.

What are the actual specs of the turbo?

Coz it might be 2 big or mismatched for the rb25 and u will waste all your $$ putting it on there and will give u shit results.

the same turbo as mine (which may be up for sale) on a auto soarer 2.5L starts boost at 2100 rpm and has 1 bar by about 3300rpm

im told it would be a little sooner on a manual 2.5L

the exhaust housing a/r is 1.00 from what i could gather. front housing is 0.7 a/r i think

not sure on the wheel sizes

but these turbos can come in heaps of different sizes

      r34's love to squeal

      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.

      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.
