GFB ATOMIC Manual Boost Controller
It is important to note that the Atomic does NOT use a "ball-and-spring" system like others on the market, for very good reason. The ball-and-spring system is an attempt to increase the boost rise rate by preventing pressure from reaching the wastegate during spool up. However, in practice this method usually creates boost spiking and a less stable and repeatable boost curve. Instead, the Atomic uses a precision orifice and needle valve system to accurately bleed pressure from the wastegate line to increase boost. With no moving parts, this system is ultimately more reliable and stable. For use with any type of petrol/gasoline or diesel turbocharger system using a traditional pneumatic wastegate (internal or external).This Part Fits: Year Make Model Submodel 1987 Chrysler Conquest Base 1988 Chrysler Conquest TSi 1991-1996 Dodge Stealth R/T Turbo 1990-1998 Eagle Talon TSi 1986-1987,1990-1991 Mazda 626 GT 1988-1989 Mazda 626 Turbo 1988 Mazda 626 Turbo 4WS 1988-1992 Mazda MX-6 GT 1989-1990 Mazda MX-6 GT 4WS 1995-1996 Mitsubishi 3000GT Spyder VR-4 1991-1999 Mitsubishi 3000GT VR-4 1990-1994 Mitsubishi Eclipse GS 1990-1999 Mitsubishi Eclipse GST 1990-1999 Mitsubishi Eclipse GSX 1996-1999 Mitsubishi Eclipse Spyder GST 1991-1992 Mitsubishi Galant VR-4 1983 Mitsubishi Starion Base 1984-1985 Mitsubishi Starion ES 1985,1988 Mitsubishi Starion ESi 1986-1989 Mitsubishi Starion ESi-R 1984-1987 Mitsubishi Starion LE 1983-1985 Mitsubishi Starion LS 1990-1996 Nissan 300ZX Turbo 1990-1994 Plymouth Laser RS 2009 Subaru Forester XT 2009-2010 Subaru Forester XT Limited 2010-2013 Subaru Forester XT Premium 2011-2013 Subaru Forester XT Touring 2009-2010 Subaru Impreza 2.5 GT 1994-1995 Subaru Impreza Base 1996 Subaru Impreza Brighton 1994-1996 Subaru Impreza L 1994 Subaru Impreza LS 1995-1996 Subaru Impreza LX 1995-1996 Subaru Impreza Outback 2008-2014 Subaru Impreza WRX 2010-2014 Subaru Impreza WRX Limited 2009-2014 Subaru Impreza WRX Premium 2008-2014 Subaru Impreza WRX STI 2011-2014 Subaru Impreza WRX STI Limited 2010 Subaru Impreza WRX STI Special Edition 1988-1992 Toyota Celica All Trac 1993 Toyota Celica GTS All Trac 1993-1998 Toyota Supra Twin Turbo
