That's not much of a difference at all. I think after seeing what you do with your setups though you might want the .63 exhaust housing. The .48 housing will tend to make a decent bit more backpressure, although it's spool time is a decent bit faster.

That's a valid point.. It's hard to find dyno graphs of the impact of different housing ARs on various vehicles.
It looks like a t3-60 or t3-super 60 are both decent choices for my application. I'm more concerned with power under the curve on this truck than peak power... Investigating a few sources for the t3 60/super 60.. I'm not willing to dump $700 on a turbonetics version.. At least not yet.

Here's what I've found so far on the 60 trim vs. the super 60...




I don't know if any of this helps, you probably already have the maps if you're doing this much research.

i dont know where your getting that at. .07 is almost nothing. there is a noticeable difference. up to you to beleive a website or someone that has used both turbos...

can you see the difference?




definately more than .07 of an inch

to me it looks like the regular 60trim has a bigger sweet spot, not thinking about the price difference i think i would rather have the 60trim instead of the super60

I see that the outlet of that 2nd turbo appears to have some port work, but it narrows. The inducers - no way for me to tell a difference just by looking at them... I appreciate the photo reference though!

The oem 60 trims have a step on the inlet. If you upgrade a T3 to a Super 60 compressor wheel, you will have to get the housing machined to match.

Rule of thumb:
If it's a GARRETT, it can't be a super 60 since the super 60 is made only by turbonetics.

that's great information, if it's true.. but maching a standard garret housing to accept an inducer that's .07" larger shouldn't be that big of a deal...

Here are a list of vendors that are selling "super 60s":

Generally speaking, every single "super 60" I've found isn't authentic, other than the ones made by turbonetics. I even have one ebayer comparing it to a "known" super-60 turbo. Turns out he had two t3-60s based on inducer size...

super 60's are very rare because they have to be purchased from turbonetics as an aftermarket turbo.
While of course, normal 60 trim t3's are all over the place because found on many factory cars.

What's the point of spending huge amounts on a turbonetics super 60 while it performs basically the same as the 60 trim?
dcg9381 is right: it's possible to over bore a 60 trim into a super 60, provided you can find that rare wheel, but why just a super 60 while more efficient and cheaper wheels are available Here, I fitted a t04B 63 trim wheel in the t3 60 housing. It will outflow any super 60.
