I bought a used SCM-6152E, it is supposed to have the GT40 comp wheel, same as what's in the GT35R.

This isn't that wheel is it....looks more like the GT37 series wheel....



Thanks guys,

Wayne


**MOD EDIT*** When using pics over 800 pixels, please use only links.

Sorry, I fixed that.

Looks like the same comp. wheel thats in my fp3565, a.k.a. GT35R. Inducer and exducer measurements would verify this however.

So your GT40 wheel has double fins on the inducer like mine, and they're slighty curved? the other pics of the GT40 I've seen were a straight single fin design.

It looke like a 50-trim wheel to me...

FP GREEN:

^^^ Im not an expert on those comp wheels, but the first pic sure doesn't look like the 50 trim wheel you posted. That 50 trim has straight blades, while the top pics are curved.

Dude, you're absoluely right. I didn't even notice that. I have no clue then. It is really hard to tell diameters with just a picture too.

I guess I'm not really asking, "hey what wheel is this", it's more of, hey, can a GT40 wheel look like this, or did I get jipped?

6152E is not stamped on the Comp housing, but actually 6169E is SCRIBED in it, kinda wierd.....

6169E is the same as the 6152E, but with a t4 hotside...wtf is going on here.....

http://arizonazcar.com/mini-GT40.jpg That's a pic of the only GT40 I've seen, and it has solid blades. The only blades I've seen that are split like that are MHI wheels.

Uhhg, someone help me figure out what wheel this is man, I'm freakin out here....

Is there a way that I could find out without pulling the cover? Or can I pull the cover without havin to replace an gasket or O-ring etc?

could I just measuer the Inducer and get a good guess.....

Man...what a shitty day....

Yes you can remove the cover without having to replace anything. Infact you probably should remove the cover so that you can spray copper gasket sealer on where the cover meets the backplate. There have been reports of compressor housings leaking. I don't know if this turbo should be suspect or not, but it's worth the effort since you want to know what the he!! this turbo is. Mic the inducer and exducer diameters. It should be enough to decipher the wheel.

My 60-1 has six 13 mm/half inch bolts. Loosen them in stages and in a star pattern (there are close tolerances in there, of course) and carefully remove the compressor so as not to bend the blades. Before replacing, make sure there is no debris on the wheel, in the cover, or on the back plate. Tighten the bolts in stages and in a star pattern... Do not overtighten. Just nice and snug.

Is there somewhere I can get actual torque specs for the housing?

Does your 60-1 have the 59mm wheel or the 61mm wheel?

Or should I ask, 5252E, 6031E or 6!52E

Also is your compressor hosuing marked in any way besides for the A/R .60?

The max torque specs for the compressor housing of that sort is 33ft/lbs. But hand tightened is good enough.

Cummon, where's all the 60-1 users here? I'm tying to discuss things will the seller etc, so I need all the info I can get here, thanks.

Well I DO have an FP RED, and it looks the same to me so.... j/k. I like your user name btw, I've used DSMonster on many forums for years . But back to the topic, like mentioned earlier you can't be 100% sure without exducer and inducer measurements. I wouldn't be too worried if I were you, as long as there wasn't to much shaft play.

EDIT: I take back what I said after taking another look at my RED. They do look similar, but definatly not the same wheel. Heres a pic of my RED.

My/all 60-1s has 7 sets of blades not 6 so. . .

And, I didn't bother measuring the wheel while I had the compressor cover off because it was purchased from a reliable vendor . But Don't let that discourage you. I don't know the diameter. It is not a 60-1. the 60-1 wheel has 7 blades. The 60-1 wheel is the FP RED wheel. Keep searching. Don't buy unless you know what you have?

To be optomistic: it does look like a big wheel .

P.S. Also, my housing has TURBONETICS in big fat letters ground on it and it does not have the A/R noted on it.

My T-netics 60-1 blades are split like that. My little garrett t3 60 trim on my stock T-Bird turbo coupe are split like that too.

I've seen a bunch of split garret wheels now, I am just wondering if any of you guys have one with blades that curve like mine do, all the ones I've seen are a straight.

I'm pretty sure this is an SCM-61, I just want to know which one. I did a half ass measurement of the Inducer, looks like 61mm to me......

Uhhg, this is frustrating...

quick FYI, gt37 and gt40 wheels are used for each other. pretty much the same thing.

Quick fyi, you don't know what you are talking about. The Gt40 wheel is a lot bigger than the GT37 wheel

If you want to know what turbo you have, take the cover off and measure the inducer and exducer of the wheel. It's a lot more accurate than having people guess.

#### it, looks like I'm gonna pull the cover to make sure of things here...to bad I don't have a micrometer here.

Ok here's what I found

Compressor housing is marked "CCE 61" on the outer edge

Inducer - 61mm
Exducer 81-82mm

All I have is a tape measure it was kinda hard to get it exact, I'll borrow a mic from work tomorrow and make sure....

So things look good there.....does anyone know how to verify Garrett wheels, by some of the number stamping on them etc?

The seller is a good guy, even called the shop that rebuilt it and asked about the wheel, the rebuilder says he doesn't rememeber the details of doing his turbo, but that he always uses genuine Garrett parts.

Looks like you have a GT35R wheel.

I know I do by the specs, so that's good, but what's up with the curve at the outer edge of the inducer blades...I've never seem that in the GT40 series wheels....

You don't have a GT40 series wheel. I think it was AGP that started the "56 trim GT40 65lbs/min" hype. There is no such thing.

The GT35R is a dual ball bearing turbo that uses the the GT40 wheel...you're saying I have a GT35R wheel....but it's not the GT40?

There is a GT40 wheel that does have a 61mm inducer, and a 82mm exducer, and it is 56trim....but that's not my wheel?....

I wish a vendor, or wiseman could chime in here.
