can you guys tell me exactly what the first numbers of the gt means and then the second numbers? Like when people say gt35r and then other people say gt3540. What is the differance? Thanks. The gt seriese turbos have always been a tad on the expensive side for me so I've never really researched them much.

I know on garrett brand turbos, it represents the hotside.
GT42xx (GT4208) = 1.08
GT3572 = 0.72
GT3540 - you're not going to have .40 hotside on a turbo that size, I am not sure where that comes from... but as far as garrett is concerned, that 2nd set of number represents the hotside.

it doesn't represent the hotside housing, but usually the compressor exducer. The first number is the class of the turbine I believe... so a gt4294 has gt42 turbine wheel with a 94 mm compressor wheel. For the gt3540, the 40 represents that it is a gt40 based comp wheel, although that particular wheel is not available in a gt40 turbo... Its not very consistent that's for sure. There's also Aspec's gt3574 in which the last number 74, represents the turbine wheel major..

It's been awhile but if memory serves the 40 35/40 comes from the 82mm wheel. being stuck on the smaller 68mm turbine. It was never a garrett designation and more of a street name used overseas (Aus) Kinda similar to when you here T3/T4 and that could apply to a lot actually. You notice on your chart that both 40 designations run the 82mm wheel.

The OP's chart just illustrates why you should not buy a Garrett turbo that costs more but is stamped with HKS on it. All the various wheel and housing combinations that most people would want to run are available from distributors like ATPturbo.com
First of all, in the "real" Garrett nomenclature, the last two numbers are size of the compressor exducer. This GT3037 for example is HKS just making up a proprietary name.
They are just taking regular garrett names and switching them up slightly so you think you are getting something that is significantly different than an off-the-shelf Garrett part. Those two turbos with 82mm wheels are GT35 compressors. The one with the 76.2 wheel is the T04S or the GT3076 (would have to get other measurements to be sure). The 71.1 is either the GT3071 or the GT2871, and the main difference between those is the hotside. The two 60mm turbos are probably the GT2560 and the GT2860.
Great example: I have a Garrett T04R with 1.0 divided hotside. HKS wants $2480 MSRP, and I think the only difference is that they clipped the turbine wheel which is not necessary for most people. ATPturbo has that same turbo for less than half that.

Coming from a marketing perspective:
Garrett Japan has a huge presence, and HKS would not be so stupid so as to rebadge Garretts and sell it as theirs.
Another note: At the 2008 Auto Salon i had a chance to see Garrett and HKS turbos side by side taken part (along with their T62R BB Prototype), and they are different turbos.
COMP/Bullseye power turbos with the triple BB turbos are great these days too. You will spend 2000-4000 dollars for these too.

I'm sure when you pull a Garrett and an HKS turbo apart they don't look exactly the same, but just how different are they in terms of performance?
Therefore the real question is, in terms of noticeable performance, is the HK$ T04R (~$2500) $1500 different than my (~$1000) regular Garrett T04R? I doubt it.

I've never heard a turbo sing like a T51R does. Haven't heard the T62R yet, but I'm sure it's going to sound just as good.
A GT45 probably performs the same, but the bling is that much more with the HKS. People buy it because they can!

With the options I have available to me now I'm not so sure there is a need. I can get a garrett built jsut about anyway I want as they can, and precision has a good line up of wheel and such to mix and match. They just need divided housings and all would be perfect with them in my book.
