This is a 155T belt and the old-style tensioner/pulley. If you look, you'll see the tensioner and pulley aren't connected. The belt is tight enough to not need the tensioner, so I'm just going to make it a fixed pulley. The tensioner is mainly on there for the small roller. I figured it couldn't hurt to use it.

With this setup, the cam pulley is 1/2 tooth off, so I may have to come up with an adjustable pulley. I've been told the 16V 2.0s use the same cam pulley......

And yes, the hood does close with plenty of clearance

Here's some pics of the wastegate actuator bracket, I had to hack it up quite a bit to get it to fit with the rotated compressor housing.

This is a what-not-to-do pic. The oil return fitting hit the bolt for the wastegate actuator bracket. I had to grind the head of the bolt down to get it to fit. And yes, the line does fit with no problems.

Here is the piping I'll be using for the downpipe and turbo plumbing. I'm still waiting for the silicone connectors, should be in this week.

One small problem I came across is the turbo oil feed line has an NPT type fitting, but the oil housing has a PG (metric) thread. I need to come up with some kind of adapter for it.

i cant see anything else except that turbo.. OMG it's BIG

DustysA4

did you actually figure out what sizes your gonna need already? Or were you gonna cut/weld(frankenstein) the stuff together yourself?

Man, it's good to see people follow through with big projects like this. I can't wait to see her up and running. Then you can make room in your garage for my car=P

You're going to run it without the tensioner?
Is that wise? I've never heard of anyone using a timing belt without a tensioner.

I think you should just convert the timing system over to chain and be done with it

Good luck, and nice job!

teh mechanic doesn't over tighten the belt or keep it loose. Once the mechanic tightened the locking bolt, the tensioner pulley is fixed, similar to xr4tic's setup.

xr4tic

to tie it all together.

Basically, there will be a silicone 90 degree bend on the turbo inlet, that goes to 3" 90 degree tubing, then the MAF and filter.

The outlet will be going over the frame rail, straight down, then curve back to go into the stock crossover tubing (which is 2")

It's all going to be cut/welded together.

xr4tic

and the tensioner will keep it tensioned correctly.

I plan on replacing the belt much earlier than the recommended 60k, probably every 30k or so, and will be inspecting it probably every oil change or so.

I can't wait to see what that monster setup does.

mau

turn w/ the diameter mentioned and not hitthe A/C fan? Which way is that piping going to turn?

xr4tic

the 90 degree silicone tube is a tight bend. I was going to turn it to the side, but I might hit the headlight.
Otherwise, I'll go down, then back up, kind of like what SmokinA4Turbo did:

I could always pull the headlight off, would be great for a ram air setup
