Hey forum thinking of getting a garret turbo with these specs:

Turbine: exducer diameter-stage2, inducer diameter-stage2, trim-t4, divided housing and a/r .84

Compressor: exducer diameter-70mm, inducer diameter- 44mm, trim-58 and a/r .50.

What rwkw range should I expect with that type of turbo on an rb25det? Will be running at least 20psi of boost through the turbo.

Engine is built with a stock head with aftermarket ecu, upgraded injectors and fuel pump.

Where are you buying it from?

Sounds like a cheap knock off, that gay 'stage 2' shit is a dead giveaway...

3076 or 3582, Garret ballbearing GT series or nothing IMO... (or hks of course)

It was an add I saw on ebay. Private seller. The pics of the turbo have garret stamped on the comp housing, just thought it was real and would be able to get me to 300rwkw. I have some pics of it attached below.

It looks like a bush bearing t3/t4 sorta thing... Got no info on the exhaust side apart from it being a t4, which is plenty big enough for that power, and a 70mm compressor wheel, and a .5 ar on that side, Which is a little small, so it would lead me to believe it's a turbo designed for lower boost on a big engine, so 20psi would be getting a little past it's efficiency range...

300kw shouldn't be much of a problem though...

I think you mean comp wheel diameter is 70mm, exducer refers to the exhaust side where the gas exits. That being said their claim that it's a 58 trim is wrong, try something more like a 39 trim.

Even though it's probably dirt cheap it's an old style turbo that's probably most suited to a truck and if you did buy it you'd have to adapt your manifolds t3 flange to t4 which would be a prick. :D

Its a truck turbo and its going to cost you lots of money to put it on only to find out its rubbish for what you want to do.

Get hypergear to make you a 300rwkw highflow and bolt it back on.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
