Hi all, I have not been a member here for very long, but I have been a lurker for over 6 years and have read probably hundreds of hours of threads. This thread is for my build I am starting on my 2000 ALH new beetle with a 02j. The engine in it has pretty bad blow by due to being driven with a bad thermostat by a previous owner for at least 50k miles. I have a good motor that I am swapping in it with 130k on the clock. I am aiming for power and efficiency. I want a relatively mild tune to keep efficiency and keep the bottom end together. I plan on tuning this myself, I have adequate understanding of tuning principals and am going to shoot for keeping the turbo at peak efficiency by datalogging, calculating, and comparing volumetric efficiency. I also am going to attempt to keep the tune smokeless.
My build plan is:
ARP head studs
New head gasket
(Mildly) lightweight g60 flywheel
McLeod vr6 clutch (40% greater torque capacity than stock vr6 clutch)
Fluidampr
Diesel geek shifter
Boost/EMP/EGT Gauges
11mm injection pump
R520 injectors
4 bar MAP
GTD1752VRK
Custom equal length header
Custom long runner intake
FMIC 2.25 inch post-cooler pipe 2.5 inch pre-cooler pipe
Custom cold air intake( with a atmospheric vent)
Future AERO mods
I plan on using the BMW Hella actuator instead of the N75 for its better response and more simplistic nature (I have chased down over boost issues, not fun). From looking at these threads below it should be do-able by using a resistor and tuning pulse width modulation only, though I am not 100% sure on the wiring of the resistor yet. The BMW actuator and N75 valve should both operate at 300hz.
Questions about:
3 or 3.5 inch intake pipe?
vr6 or r32 MAF?
2.75 or 3 inch exhaust?
My questions for you all are:
Have I vastly overlooked anything?
Should a vr6 MAF and 3 inch intake pipe be adequate or should I jump up to r32 with a 3.5 inch pipe?
The rough calculations I did for piping sizes all pointed to 2.75 inch exhaust, will I notice performance losses from going to 3 inch? (3 inch is more widely available)
Is the best place to purchase a stock GTD1752VRK in the US Darkside Developments? They have them for about $1k including shipping and tax.

Electronic actuators using N75 on MKIV
I'm looking for some help on a turbo upgrade project. I've got a GTB2056VK on it's way. I have read somewhere that it may be possible to remap the N75 to control an electronic actuator. I do not have the technical knowledge to figure out the computer side of things, but I am quite adept with...

Somebody PLEASE do a direct PWM turbo controller already!!!
We tested the BMW PWM actuator with pulse generator and the working range was ~290Hz to ~310 Hz. Mercedes actuator is supposed to be ~140Hz. Both actuators have same part number so you have to know what car was it from. You can simply swap the cover from BMW ectuator to VW/Audi actuator and it...
