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...
