Oh boy, you're going to love a boosted VR6.

First things off, what are your power goals? What is your budget? What are you looking to get out of it? Do you want a laggy turbo? Do you want a turbo that spools up at 3k rpm or 4.5k rpm? Kind of depends on what you want.

Engine wise, the VR6 is a great to boost. With a headspacer (to lower the compression) and head studs you can get some high numbers. Whereas with the 1.8T you need to pull apart the whole block, new rods, valves etc.

Most people boost up to 10/12 psi without any engine mods. That's a safe point. With Head Studs and Headspacer you can up the boost and ofcourse, More Power!!!
When adding a headspacer, the VR6 becomes a non-interference engine, which is always good!

Lots of information online, do you research and always double check!

$2000 ain't gonna do it, 2JZ boi. Start stripping out weight if you want it Fast n Furious and spend that money on maintenance items, its going to need it.

Speed kills! You should look into slowing your car down to be safer. I'd suggest running some aftermarket software that drops 3 cylinders while driving to conserve gas.Also install a governor speed limiter and set that to around 67mph maximum top speed.
