Until you measure the actual turbo's that we're talking about, I won't rely on the fact that you work at a turbo shop or that you feel so superior in knowledge to a guy that simply measured two different turbo's and didn't find a difference. You're not fooling anyone.

the exducer size is the same between a .42 and a .60 compressor, so you can use the same backing plate, just put on a .60 compressor wheel and compressor cover. Only the inducer size is different.

Did you not say this? Were you not talking about the 50 trim wheel that is found in the .42 A/R housing? Regardless of what car you found it on, your numbers don't matter. Quit saying .60/.48 which are A/R terms and have little to do with this discussion.

The .60 A/R has a 60 trim wheel and the .42 A/R has a 50 trim wheel, regardless of what car you took it off of. They're still Garrett T3's and are still the same turbo. You still suck at measuring, and you're still wrong. Why you can't admit defeat is something that YOU have to work on.

I'm showing you proof and you're still struggling to hold on. You lost a long time ago.

Close. The exducer is the same on all Garret T3's. What seperates them is the inducer. Of course you can fit a 50 trim wheel into a 60 trim .60 A/R housing, the 50 trim wheel is smaller by 4mm overall diameter. Try putting a 60 trim wheel into a .42 A/R housing and it won't happen without a change to the backside/inner radius of the compressor housing.

But tell that to thick headed Steathmode who can't take being wrong.

You must be forgetting that one of us actually measured the turbo's we're talking about. I said that JD mentioned they were different but didn't say why he thought this to show that:

1. I measured them, and didn't see any difference whatsoever.

2. JD said they were different, but didn't say why he thought that.

Simple study of communication will show that I was giving a reason why I could be mistaken, but it hadn't been discussed. Your simple this is that and that is this and I'm supposed to have missed a 4mm difference isn't cutting it. Especially since you haven't even measured the two turbo's we're talking about. You're going off of theory, and against a real world measurement, I'm not seeing how all of a sudden there was a 4mm difference when there wasn't.

Yes, I need to be right soooo bad that I offered up another theory after stating what I saw. If I wanted to be correct sooooo bad, I wouldn't have even offered the unbacked opinion of someone who said they were different. The bottom line isn't who needs to be right, it's what is right. What is right can't be found by a self proclaimed turbo genious without the two turbo's in his possession. How many times do I have to say it?

Hey look, here's a super 60 "60 TRIM" with a .42 A/R COMPRESSOR HOUSING. Durka durka.

Interesting... I knew you could put a 50 trim in a 60 housing, but I always thought it would never work right? I thought if the housings didnt match up to the wheel ( being 4mm or whatever it is) smaller it may not boost right? Is using the larger housing with a smaller wheel going to benifit that much?

hmmmm, maybe I should just try it since I have several sitting in the garage.

my guess is that with a 50 trim wheel in a 60 trim housing youre gonna be losing a bit of compressor efficiency because its probably gonna have to spin faster to create boost because of the improperly sized inducer on the 50 trim wheel if used in a 60 trim housing, but itll probably still boost fine.

I have that turbo with the same .42 a/r housing. Maybe I'll pull off the compressor housing and measure the blades for you guys, but all I have is a cheap ruler.

With every reply, you make it abuntantly clear that you completely have your head up your ***. Did you miss the part about a 50 trim being a 50 trim wheel whether it's in a Volvo or Saab? Do you think that they have different Garrett T3's? Different sized 50 trims? Do you understand how to calculate trim? I'm not talking about measuring, I'm talking about calculating. If your mathematical skills suck half as bad as your measuring skills, it's a good thing you don't run a turbo shop and stick to stupid things like mandrel bends and silicone couplers. That kind of easy ---- is right up your alley.

Exactly. Because you suck at measuring, we've already found that out.

Becasue he measures correctly, and you don't. I bet his IQ is higher than yours and mine is higher than both of yours.

Wow. Now we're getting somewhere. Are you admitting that you measuring sucks? After I SHOWED YOU WHAT A 60 TRIM LOOKS LIKE, COMPARED IT TO TURBONETICS NUMBERS, NOW YOU'RE STARTINGT TO REALIZE? Do you not understand what makes a 50 trim a 50 trim and what makes a 60 trim a 60 trim? Do you think that because Turbonetics shows measurements for a 40, 50, 60 trim and I showed you that a 60 trim is exactly as they say as well that a 50 trim is the same measurement? Are you really that stupid?

You need help. Luckily you only sell couplers.

I've measured more turbos than you've ever seen in your life. Did you miss the part about a 50 trim being a 50 trim whether it's in a Saab, Volvo, or T Bird, etc etc etc etc etc?

You're the wishy-washiest motherf#%ker I've ever argued with. You've changed your opinion so many times to try and get out of being wrong that you just keep rambling and keep making yourself look worse. You've been wrong since the beginning and I've called you on it from the beginning.

Do you honestly think that there isn't a difference in the 50 trim when I clearly showed you what a 60 trim is supposed to look like and conveniently Turbonetics numbers back it up? What about the obvious difference in compressor map. Is Garrett lying about that too? You're a fool.

Urine idiot. The Super 60 measures 2.367" major and 1.900" minor. Itl works out to be a 64 trim. Do you know how?

I'll show you:

1.900^2=3.61
2.367^2=5.602689

3.61/5.602689*100=64 and whomever is selling that turbo is as moronic and ignorant as you are. the .42 A/R housing can easily be machined with a bench lathe. You do know what a bench lathe is right? I bet if you took the compressor housing off you'd find someone hacked away at it with a dremel instead of doing it correctly. You can fit whatever you want with whatever you want provided you're not an idiot, can measure correctly, and have an IQ higher than 4mm or .156"...wait...I meant an IQ above 95.

Durka Durka.

Only on the butt-dyno. You can fit a 50 trim wheel ina .60 A/R housing but you'll have trouble doing the opposite with a 60 trim wheel in a smaller housing. This is because the wheel is larger on the 60 trim. Something Stealth still doesn't grasp.

Exactly. And for that you'll get better results on the butt-dyno. You should read Stealth, these guys are smarter than you when it comes to this ----.

You won't know which wheel is which until you measure. When you do, you'll get these results: http://64.225.76.178/catalog/comp_wheels.html just like the 60 trim wheel that I showed you earlier. The 50 trim measures 1.674 and 2.367 respectively.

1.674^2=2.802276 and 2.367^2=5.602689

2.802276/5.60289=0.5001662*100=drumrrrrrrrrrrrrrrolllllll.5 0 or 50 trim.

Hopefully this will now sink in to Stealth but I highly doubt it.
