Key Features / Product Warranty
We now stock 4 of the most popular N75 valves:
034H "Race" Valve - OEM style N75 valve, this is the fastest reacting valve with the higest boost capacity of the N75 valves we've tested. Also works well for universal application boost control like with our new Stage I and IIc ECU's. Also known as the "H" valve and came stock on 2.2 Turbo 5-cylinder applications like the 3B and AAN, offers a 1-2 psi boost increase in newer 1.8t and 2.7t applications.
058 F Valve - This valve is stock on all 1.8t motors and is a good stock replacement.
078 B Valve - This valve is stock on all 2.7t including RS4
034 J Valve - This valve is stock on 3B motors and is a good stock replacement.
These valves are a "bleed" type valve, boost signal pressure to the WG is bled off to raise boost, simple 2-wire PWM solenoid.
We can supply virtually all versions of the N75 valve, just shoot us an email if you're interested in a different version.
INSTALLATION - bottom port to turbo pressure, short side port to wastegate, long side leg to turbo inlet or vacuum or atmosphere.
