Turbo and Supercharger Parts

About Turbo and Supercharger Parts

Chasing more boost? Here's the thing about this part of the catalog. Everything on it leans on something else. The intercooler keeps intake temperatures down so the ECU isn't pulling timing on you. The charge pipe replaces the plastic one that splits. The valve handles pressure when you lift, and the wastegate decides how much there is to handle. A turbo upgrade wants the whole list, plus fuel and a tune.

Here's the order that works. Tune first, since the factory map leaves plenty in the turbo you've already got. Intercooler and charge pipes next, for consistency more than peak. Turbosmart and GReddy valves after that, mostly for sound and to replace a factory valve that leaks at higher pressure. The turbo swap comes last, once the tune has run out of turbo to use.

Superchargers are the other route, and they're the one that suits the naturally aspirated cars in here. A roots or twin screw kit brings torque from idle. A centrifugal builds with revs the way a turbo does. Either one arrives as a complete kit with the tune, because a blower without fuel and timing changes is a broken engine. Most of this section is off road only and you'll see that on each listing.

Common questions

Does a bigger intercooler add power

On the first pull of a cool morning, hardly at all. On the fifth pull of a hot afternoon, plenty, because the factory core has soaked and the ECU is pulling timing to stay safe. A bigger core holds intake temperature steady so the car makes the same power every run. Peak numbers barely move. You're buying repeatability.

Is a blow off valve bad for my car

A valve that vents to atmosphere on a car with a mass airflow sensor makes it stumble between shifts. Metered air walks out of the system and the ECU runs rich for a beat. A recirculating valve or a hybrid that vents a little fixes that. Speed density cars don't care either way, so a vent to atmosphere is only a problem on a mass airflow car.

Turbo or supercharger on an NA car

Supercharger, nearly every time. The kit comes complete with the tune and the fuel parts, goes on in a weekend and gives you torque from idle. A turbo kit on a car that never had one means a manifold, oil lines, an intercooler, plumbing and a tune from scratch. The turbo makes more at the top. The supercharger's the one that actually gets driven.

Do I need a tune after a turbo upgrade

Yes, before the first full throttle pull, not after it. A bigger turbo flows more air than the factory map expects and the fueling goes lean up top, which is how engines die on a dyno. The kit listing names the tuners who support it and the fuel system it wants. Pipes, cores and valves live on the factory map. A turbo doesn't.
