Need some help with the different style 5-bolt turbine outlet on a Garrett T3/T4

As soon as I can find the correct turbo, I'll be upgrading...

Hopefully will be getting a T3/T04E, 50 trim, .48 a/r turbine, INTERNALLY WASTEGATED (yeah, yeah, I just want to get the engine running first before changing anything...)

My question:

What are the different 5-bolt style turbine outlets for T3s?!?!

Because the turbos I'm looking at seem to have a "thicker" 3-bolt mounting point for the downpipe (that is, such turbos are longer from the tip of the inlet of the turbo to the tip of the discharge where the downpipe would mount flush)

Here's a pic:



Now here's a pic of my CURRENT turbo:



If you notice, the distance ( E minus F) for my current turbo is far less than the distance on the first picture...meaning if I got a turbo like the one in the first picture, i'd need to re-do my downpipe.

However, what I want to do, to get around this, is to just swap the 5-bolt internal wastegate assembly from my existing turbo and bolt it to the new turbo.

My question is, are these internal wastegate assemblies INTER-CHANGEABLE?!? That is, is the 5-bolt outlet of the first turbo the same as the 5-bolt of mine???

I heard that the first one is a "mercedes" style 5-bolt pattern, whereas mine is a Ford style? (it's a garrett turbo)..But I have also heard of a "saab" style and "volvo" style 5-bolt discharge.

What's the difference between them? Is the Mercedes distinct from the ford and all the other ones, (and does ford/saab/volvo use the same pattern?)

Here's another picture of my turbo (which has the same .48 a/r turbine as the one in the first picture):

Now if anyone has a T3/T04E lying around, would you be able to take those measurements for me??

Because if I can assume that the T3 .48 A/R turbine housing has the same 5-bolt style as all other garrett t3s, I could buy a non-internally wastegated one and use my wastegate assembly from the existing turbo...

Here's a back view of the first turbo...it looks very similar to mine, but of course, I can't be for sure without knowing measurements. Basically, if they're both 5-bolt garret turbines witht he same a/r, is it guaranteed that the bolt patterns are identical?



I know this is a pretty technical question, but can anyone tell me what the hell the differences are between all these 5-bolt discharges?!?!?

Thanks...

Hmm..might have just found the answer...



Those are the dimensions for a TK049 flange- T3 5-bolt Garret Ford / Turbonetics / Garret Saab / Garret Volvo Garret aftermarket / PTE Flange.Does not fit M.Benz T3 turbine housings or Nissan T3 turbine housings.

I mean the turbo's a garrett...but I'm still not sure if all garretts of the same .48 a/r turbine have that same 5 bolt pattern...guess I'll just need to measure mine and see...

if it's a garrett housing, it should work.

There are 2 kind - garrett and mercedes/ford outlet.

Here is the garrett one:



Next time, SEARCH!!!!!!!, hehehehhe, I had to say that.

The 5 bolt pattern will be the same on garretts... it's the inner circle for the turbine that is different.

I basically had the same question. I posted up last night.Here's the link.zerothread?id=158916I was going to get the 5 bolt flange I linked to ATP turbo. Is this the right one? http://www.atpturbo.com/Mercha...e=FLSI was told to get the mercedes 5 bolt flange. but the hole is small, right about 2.3" like it says up there.

I think that is a high flow swing valve assembly. I just bought one off ebay. That .48 A/R might give you trouble though.

Yeah, so I had my dad measure my turbo (car's in CT with him, I'm down here in Chapel Hill NC at school) versus that flange, and NONE of the measurements are the same, meaning I wouldn't be able to swap out my wastegate assembly for another .48 garrett turbine.

And i'm not worried about the .48 a/r...this isn't a race car, a dyno whore, or a drag king...I like boost and throttle response, and I like it immediately. It's the small compressor of my turbo right now that's giving me trouble....not the turbine. People have made well over 300 whp with the .48a/r T3/T04E

So my question: WHY does my Garrett turbine have a completely different pattern compared to the others?!?

Guys...I still need help with this!I aim on getting the car running spring break (March 10), and need to get a new turbo soon...

WHAT kind of wastegate assembly is this?

It's from a Garrett T3 .63 a/r turbine



DOES ANYONE know where I could get the measurements for THIS style of 5 bolt discharge? I have a feeling it may be the same as the kind on my turbo, albeit with a different style wastegate assembly...

Is the above picture the "ford" or "nissan" style 5-bolt pattern!?!?

Never realized there was a difference.Check out MJM turbos page. They have tons of pics, so maybe you'll see something to help you out. http://www.mjmturbos.com/AAAmjm2ndpage.htm

I dont know if this pic shows different swing valves for the same bolt pattern, or if one's THE Garrett and the other's your version.



I never done business with them, but they seem to work with a variety of turbos. Maybe they could help you out if you give them a call.

I just found out the hard way that there are two Garrett 5 bolt patterns. A large and a small.

Why don't you measure yours and compare to the diagram. I have a large pattern and the DP attaches with a 3 bolt flange. The small pattern I believe has a tapered lip that the DP presses onto.

You have a super 60 now? How much boost/HP and how do you like it?

Thanks for the info...that's a helpful site...looks like I'll give them a call.

Actually, they're in South Windsor, CT, which is only about 25 minutes from where I live (but I'm in Chapel Hill NC right now)...I'm sure they'd know exactly what I was talking about though...

As far as the T3 super 60 goes--never dynoed it, right after I had it broken in, engine self-destructed.

Was running 10 psi for a while before I had the engine built. It made decent power, and spooled ridiculously fast, but it ran out of steam past 5000 rpm, hence my desire for a larger t3/t04e hybrid.

Came across this thread today. I didnt read it all, but there is some discussion about the two different 5 bolt outlets.zerothread?id=110586
