The charge for this machining would be $100.00. We would not suggest it however, the wheel is heavy and inefficient and would not work well with your engine. They had more negative effects than positive, so they were replaced with the wheel that you have now
this is what gpop told me... very interesting it makes sense too since the merc turbo diesel was available in the late 70s, where the vw didn't get introduced until 1983. great info.
and then i asked them, excluding the effects of the mercedes turbine wheel being heavier and less efficient, how does the larger turbine inducer with the same exducer effect things?
In theory the larger fins catch more exhaust flow and cause faster spool up. What was found though was that it was better to direct more flow to the turbine than to try to "catch" more flow. They also found that more curvature of the blades (instead of straight paddles) not only "caught" more air but also started the flow in the right direction reducing turbulence. We hope this helps, let us know if you need anything else. Thank you,
so keeping this in mind, the newer staged wheels for the t3, all have the same inducer size as the mercedes, but they also have larger exducers as well, which increase as u go to higher stages. they also are curved and more modern in design than the ancient oem t3's, so with even just a stage 2 wheel, you would be able maintain or gain spool up, while increasing flow greatly.
yay i did some work on it this past week or two... just small stuff
Mind if I ask what the copper tubing to going to be for?
I would think a driver pressure gauge.
Yeah for an emp(exhaust manifold pressure) gauge. for the turbo I'm putting on I'm not particularly concerned but in the future I plan to experiment with bigger compressors possibly a 50 trim to4e. But I'd really like to find a 50 or 55 trim t3 Compressor with the stock vw turbine housing bored out for a stage 3 turbonetics turbine wheel that should be good for a fast spooling 200-250hp. Unfortunately tho the 50 and 55 trims are pretty hard to find and usually cost more than I wanna pay for a 30 year old turbo
Cool thing is tho it gives u an idea of when you're running too much boost, or if u can crank it up some more
not that i got much of anything done, but i have the turbo put together and most everything bolted to the head. i just wanted to post the picture because i think its funny how the turbo looks almost completely stock yet it can flow nearly 100 more hp than the stock turbo. it is the stock vw hot side and a volvo 50 trim t3 compressor. ported head, ported intake, ported aaz aluminum elbow, and ported exhaust manifold.
Oh the joys of a build taking 2+ years. You sir are dedicated. And if I liked turbos I'd say that's a pretty sexy picture right there.

hey i'll never give up on this car, its just my little project for when i have free time or need something to make me smile, doesn't matter to me if it takes 10 years, and i'm a car guy so i'll always have a project of some kind. although the build is more like 8-9 years since i've had this car from when i was about 15-16, and its been off the road for 4 years. right now i'm kinda stuck on a decision i need to make. i ahve my 81 rabbit i got 5 years ago with only 85k(130k now), its a clean one with almost no rust, and we all know nice rabbits don't grow on trees anymore. So i don't like daily driving it like i have been for the past 5 years, and i found a pretty nice tdi to buy from someone i trust, but then i
should sell my rabbit cause there is no purpose to having so many cars, and so little money haha.
