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.

Ive seen alot of people recommend this: https://frenchysperformancegarage.com/products/fpg-nissan-skyline-r33-r34-silvia-s14-s15-billet-fuel-tank-bulkhead-hat-top-an6-with-high-current-connector-apex-2-8-delphi-fpg-100?variant=42873255198898 My current pump that stopped working is aftermarket but I had no relay mod or upgraded connectors.

      It’s new. It’s the cd009. I did take the transmission apart to mill down the bellhousing and had both housings come off the gears so wondering is something isn’t in right. I am running redline. I can get it in gear running too but it’s just not easier and it’s almost like 2, 4, 6, and reverse all the back gears aren’t happy going in

      Got keys and did a walk around the yard planning the landscaping works with the family that I will be doing Main effort: remove all the woodchip in the gardens that are around (attached) to the outside of the house and replace with 10mm blue metal, having woodchip close to the house is a recipe for inviting white ants, currently there are no white ants within the block and I would like to keep it that way I'll be buying some large raised garden beds to grow veggies and stuff, and the woodchip will be mulched with everything else that gets dug up, pulled out, or cut down during works Next will some minor drainage and landscaping maintenance up one side of the house, where the fuse box, AC, and solar stuff will go, about 12 mtrs long by 2 meters wide, I'll break up the soil, add gypsum and then I'll dig in a French drains about 300mm deep x 300mm wide and fill it with agg pipe and blue metal, then level out the whole area with a 50mm layer of blue metal, the soil, whilst currently pretty compacted, will break up well with the gypsum to aid in drainage, I'll then cover the area with a 50mm layer of more blue metal In saying this, the drainage issue is minor, but that little hidden away area down the side is untidy and weedy, and as all of the main elec stuff is there I want it neat and tidy to appease my OCD Again, the material excavated from the French drains with be added to the garden bed mulch, as will some rose bushes and some other crap looking garden plants, and a old apricot tree that is looking worse for wear The apricot tree is currently in a little roundish garden bed that is in the middle of the back yard with few other crappy looking plants around it, that will all be removed, levelled, re-turfed, and is a perfect spot for a hills hoist There is also a area about 3m x 2m between the rear fence and shed that will get some attention, it looks like some stuff was stored there and the grass is dead, that will also get broken up and mulched, and is a prime spot for a pumpkin patch I've guestimated that I'll need: 3 tonnes of blue metal, 12 meters of agg pipe, 5kg of Gypsum, and a hills hoist, so a few bags of concrete as well to set it in place (the house currently has one of those pull out 4 line jobs, whilst it works, I want a retro old school hills hoist), I am also going to run some chickens, there's a great spot for a coop, so a chicken coop to suit 4 of those lovely egg laying bitches will also be on the job card That should keep me busy for a while, and will finish off the back yard ready for a early spring planting of some veggies and berries  Once the main effort is done I'll start out the front, there's a large rock garden that could use some TLC, but that is only minor works Should be fully moved in within 2 weeks, the landscaping works will start then Fun times, retirement is good

      Steps to DIY sanding car back ready for respray....

      It happens, that's what your single stage filler is used for.  If it is still visible after the 3 coats of 2k primer, it will be visible after the paint is laid down.  Its hard to give 100% perfect advice without being there in person, I'm very tempted to say stop where you are, fill your pin holes with a single stage putty first then keep going.
