Yet another turbo choice thread - what is happening in the turbo market these days?

OK, here we go, I'll try to keep this short:

-I did my homework, albeit more than a year ago.
-the turbo is going on a built RB31dett (forged, cams, etc).
-having looked at compressor maps and similar builds on here, I am going for something with similar dimensions to a T88
-I have started collecting parts, including a good quality tubular high-mount manifold with a split-flange, merge-collected T4 and (TiAL) twin 38mm external wastegates.
-Given how much I spent on my motor, cheap chinese turbos are out of the question. I want good VALUE, in terms of price per performance/durability. I understand I will have to pay for that.

At that time, there were limitations in what features a T88 turbo could have. Few had ball bearings, none were water cooled, I don't recall seeing any billet compressors.

My question is, which of the following features on my wish list can I now have in a reputable brand, and where is a good place to buy it:

-T88 size
-ball bearing
-water cooled
-billet turbo wheel
-t4 split flange
-(are there any other features I should be chasing)?

I'm surprised both of posters above didn't say Borg Warner EFR.

Me too!  however if it were me then I'd go the EFR9180 1.05 EWG which would be perfect for an RB31  for everything except drag racing.   My 2 bits haaa

I always say it depends on application, given a turbo size like that my gut feeling its a drag racing application, and a 9180 probably wouldn't really be suited. Also i don't think it'd be big enough anyway.

There might be a non EFR borg warner of a good size that would be ok (SXE range?) but i don't know anything about em, and the precision might be just as good/better.

Interesting that your last year's search ended up with T88 variants as that was 2006 for the GK and in the 90s for the D.

They were all +1000hp turbos so none of the EFRs would do the job on the top end. Considering you want water cooled turbos then you are basically looking at Garret GT42 and above or BW SX lines as mentioned above.

That's S400SX-E territory as the 500 seems to be T6 flanged. Not familiar at all with these turbo either but they're not BB nor watercooled. I don't think that BW is doing any BB/WC CHRA of this size, and for what I see garrett is only doing watercooled one. To big for ballbearings I think.

The first suitable would be a GTX4202R as it has billet wheel, is watercooled, available in T4 twin scroll and about T88-38GK power rating.

Thanks for the responses - All very useful.

In terms of goal/usage, I am trying to selection the turbo to match the flow potential for the motor more than anything (the current twin low-mount HKS2530s are just producing heat and not much else above 23psi), and usage will be occasional weekend use (although at some point I'd like to take it to a 1/4 mile).

Having the actual model numbers/names of these turbos makes googling around a lot easier.

It seems like advances in technology are allowing relatively smaller turbos to flow more air, which is a good thing.

The GTX4202R looks to be a very good contender so far - but how come they all quote the price without a compressor housing? Not a big deal but just seems strange.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • 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.
