dont see why not, i have an ALH turbo (VNT 15) on my 84 rabbit..

so, anything like that should fit similar..
92 Jetta GLI - Black, 1.6D w/ GT2056V turbo..
86 GTI - 4 Door, Med Twilight Gray, Tow Machine..
86 Audi Coupe GT - Tornado Red, All Stock.. WRECKED.
89 Toyota 4Runner - Dark Grey Metallic, LIFTED!

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

oh okay, I just wanted to make sure it'd mate up to the 1.6 block.

look at the exhaust manifold, if it LOOKS like it will fit, it most likely will.

theres only a couple different manifold patterns, and the ones that dont fit, it will be completely apparent..

what year beetle are you getting a turbo from?

so, that SHOULD be an ALH right?

or was it some other code?

That might be a BEW. You will not be able to control boost with that turbo unless you make a custom actuator.

BEW has different exhaust pattern port doesnt it?

why would he be un able to control the boost? its a VNT isnt it? not like they really need much controlling, unless you want the vanes to work so they spool faster..

All the 8v heads have the same port spacing. It's not until the common rails with the 16v heads that the manifolds change. Well, there is one euro 16v PD that is also different.

He could just keep the vanes at a fixed position like you mention, but I don't want him to think he can just hook up a tube tapped to the intake and attach it to the vacuum can and think it will work like a wastegated turbo.

The OEM BEW turbo has a fully electronic servo-motor vane actuator... previous versions were vacuum-controlled.

It's probably PWM, but dunno for sure. Some research will surely be required to control the vanes without the rest of the BEW bits and pieces... or it may be possible to retrofit a vacuum-controlled actuator.

good point, about the electronic vane control..

No, it's vacuum controlled. I don't believe any VW turbo uses electronic solenoids to directly drive the vane arm. Unless you are referring to the electronic sensor on the vacuum can, which is just a position sensor, not an actual solenoid. Mercedes uses a solenoid to move the vanes.
