Need help installing a gtx3076r to my rb25det

I have a stock turbo setup on my RB25DET and received my first turbo replacement today, the gtx3076r. I wanted to know what parts I need to complete the installation, thanks!

The standard turbo is a T3 flange so the turbo will bolt up in factory position providing you haven't got a special rear housing like a tial one. The downpipe will need to be modified to match the v band flange rather than the garrett 5 bolt pattern. Then custom air intake and intercooler pipe work. I'd imagine you can make the standard water lines work with a slight bit of tweaking oil feed may need to be a custom braided line

The gtx3076r is a T3 .82. How will I have to modify the downpipe to match the v band? Do I need new gasket rings, inlets, outlets, any other connections?

Don't forget injectors, boost controller, wastegate, ECU and a tune. You'll also need a Z32 airflow meter unless you're going with a MAP sensor. The 10mm spacer is put in between the turbo and the manifold to prevent the compressor housing from touching the cylinder head. Just fabricate a new down pipe that will bolt onto your existing exhaust system, but you'll need a V-band flange to attach onto the turbo.

Then there's the clutch to support the power, tyres and wheels for traction, possibly coilpacks etc

You didn't mention if it's internal or externally gated. The process is a lot simpler and cheaper if it's internally gated.

      The previous switchover point was 501mv. The stock value is like ~360. They now were idling at about ~880. The thing is, most people get a false lean condition. I am getting false rich conditions. This isn't a quirk of terminology, most cam upgraders get awful fuel economy because the O2's read false lean and add fuel - Mine are attempting to aggressively subtract fuel.

      So... the whole idea was to upgrade the power of the motor from stock. The motor I bought with the gearbox had 'some' stuff done to it in the past, but it wasn't as well thought out/what I had wanted to do. The stock heads typically are a big restriction on LS's and need porting to unlock quite a lot of power. You can then go a bit silly with aftermarket castings to get more, aftermarket intake manifolds for a little more, and then porting those for more. <- We are here. Nobody in Australia really goes down this path (for some reason). It might* make 3kw or something more than doing things the tried and true path for 10X the cost. So that's probably why - I wouldn't even recommend it to people, the money was and is likely better spent on just CNC'ing the stock heads and putting a 6.3L stroker kit in. I didn't want to go down the 'normal' path and then think: But if I'd just done a bit more - I could have had a slightly better result. I assumed the heads were running out of flow and it always annoyed me - Turns out the previous installer advanced the cam 6 degrees so this is likely why it was coming on earlier and running out of puff earlier than advertised. The body panels were just lack of planning/no information on this anywhere on the internet and the fact they came out different was annoying. From test fitting the guard it appears I could have gotten away with GTR guards only, but I got the bonnet and raisers and everything else as well for a pretty decent package deal.

      So you had a car that by all accounts drove well and survived track days, and that was looking great after months of being stuck at a paint shop. Some might call that a finished project. But you decided this is not quite right. So now the car does not run anymore. And the engine doesn't fit anymore. And the body parts don't match anymore. But, this is progress somehow. Greg, I think your subconscious does not like you and does not want you to drive this car. (I know I know, this whole escalation was not intended, but man, what a rollercoaster)

      Yeah, but the narrowband is truly narrowband. So you take it out of the linear zone and it is effectively nonsense. And that linear zone is so literally narrow, that nonsense is not very far away. Unless they are flicking back and forth across the stoich point, for real, under actual control, they can't be trusted for anything except entertainment value.
