Go look in your local phone book for hydraulic shops, then call them up and you can probably find one that can make lines for you.

I recommend a rounded tip cutter like the one I linked to. The Prussian blue is handy for determining exactly where the waste gate flap is making contact.

It was an ebay listing called:
For Turbo Charger T3 Internal wastegate COM.42 A/R 45 Trim.48A/R

But that is no longer active.

In other news this blew a head gasket on the first ride, some pics:

Porting just the hole didn't do the trick, you will need to do a lot of porting of hole and make a valley to the hole. What I ended up with was sort of like this but without the deep valley near the flange.

here is a pic of the car almost finished. it made around 250 on the virtual dyno at 15psi boost creeping. I will see what I can do now with the ebc hooked up...no more power but a lot more midrange

I still need to work on the undertray and get the slicks mounted for an event this weekend.

Megasquirt, 670cc injectors, 212KPA. It has an open downpipe that I cut right to about 15"

I have since dialed the boost back to 175kpa

I got a steal on these rims and mounted some used SM7's on there for now to learn the car. Will probably go with A7's or the RS4's eventually depending on whether I really want to switch wheels at events.
