Hello everyone this is my first time posting so to start off Im Neil and I currently own a brown 1983 Audi 4000s and a Emerald green 1994 Urs4. Im Planning on doing a build in the near future with the Urs4.
Im aiming for around 400whp.
Heres My list of parts so far i Plan on using:

Scat H-beam rods
Arp Head studs
Gt3076r a/r 63
630cc injector
FMIC 30inx9.25in
V.E.M.S

Any input and ideas are welcomed and appreciated Thanks and happy holidays!

That list is a nice start. Sounds solid. You'll need a clutch eventually. Welcome!

Welcome!

Apparently you should probably pick up an Iroz efr turbo and manifold kit. No external wastegate makes it cheap and simple and the power numbers are crazy!

This.^^^

But if you stay the GT3076 route, I recommend going with a .82 a/r hotside instead of the .63. The .82 is more efficient and the .63 will likely surge on you more than you will like. BTDT with the .63.

Which SB clutch did you go with? Stage 2 endurance seems too little but looks like what you got there at least by the color of the pressure plate

HX35 is a great turbo for the URS4. It's just like a 30r, but spools 200 rpm slower (approximate).
