Help me build a stock looking, compliant TDI MK4/MK5. PD130 or PD150 look stock? VNT17 or BV43 or gtb1756 bolt on?

I've been researching building a TDI engine. I know ALH/BEW are capable of a bunch, but what about looking factory?

If I built a FWD BEW/BHW, would it look factory like a BEW? Would a PD170/BV43 or gtb1756 or VNT17 turbo be nice and low key, no custom manifolds, no FMIC? What turbos should I run? What power level can I expect?

Should I find a PD130 ASZ or PD150 ARL instead?

I'm trying to keep things as emissions compliant as I can in California. I'm subject to visual inspection, obd plugin, and a smoke check. I know I can get 174 from a BHW on factory hardware, but unsure if I can use VNT1749a in a FWD configuration with FWD manifolds.

Cook me up a stock looking bang for buck compliant looking TDI recipe.

Things that look stock. Stock intake, keep egr, Vnt17, and larger nozzles. Have Malone do a tune, and then knock the IQ back a little so it smokes less during inspections.

We have emissions here to so I'm in the same boat.

So I might be able to get by on an VNT17, good to hear. There is..what..170whp if I do it right?

Is the stock BHW turbo (VNT1749a) the same as the VNT17 that everyone uses on BEW? Is a BV43 bolt on?

Thanks Morg. What check do you do up in OR? What have you done to your car?

I'm not certain what the gains will be with a BEW turbo, but the vnt17 looks very stock.
I have a vnt17, 1019 injectors, Malone stage 4 (with EGR still fully functional) and a 2" exhaust. I also have the catalytic converter and a magna flow muffler. No issues yet and I had to run emissions early last year.
