just picked up a vnt-15 turbo off an 02 beetle from a buddy. with like 35k miles on it.
Anyways from searching ive done it looks like setting up a controller for the vanes is a kind of a pain in the ass. And altho ive read through quite a few threads.. i dont quite understand limiting the boost of them. i understand the opening of the vanes to ither stop the building of boost or to stabilize it..?
sorry definitely not a turbo guru when it comes to diesels still so much to learn, and ide never even looked into these turbos with opening and closing vanes before until i brought this little guy home last night.
I guess im wondering if its worth going through all the trouble of setting up a controller of sorts.. or if ide be better off sourcing a regular turbo.
this would be going on a 1.6 n/a with a td pump and through a small intercooler. Ive no intent to run big boost.. or a big turbo i just want to add that bit of pep to the diesel for hills and getting on the freeway and such.
thanks for any info you can provide or just pointing me in the right general direction.

If you don't limit the boost it will act like a small turbo with a stuck wastegate, it will overboost and blow stuff up eventually.
That's the point of the VNT, it can act like a small turbo at low rpms and a larger one at high rpms.

right i understand that, i just need to find more info on these things.
the more i read the cooler they sound and less of a PITA a vane controller seems.

Named Tintin, Libbybapa and I all have different versions of controllers for them, and all seem to work well. Just do a search, and you should find details on all of them.

I'd also recommend looking up the differences between the n/a engine and the turbo engine before you make up your mind fully on a game plan.
Yes all the parts will bolt on, but there are quite a few differences between the engines (in particular the block) which help the engine deal with the increased heat and pressures caused by a turbo.
Just be a shame to go to a lot of work on a controller only to have the engine go boom down the road a ways !!

yeah, i know an n/a and turbo block/head differ.
but i really have no plans on super huge amounts of boost.
im looking at getting a whole td setup.. eventually.
its all just ideas right now anyways.. always try to gather as much info as possible before i actually jump in.
