Turbo Kit for Volkswagen Golf Jetta Corrado VR6 12V (1992-1998) 2.8L

Complete intercooled T3/T4 turbo package for the 1992–1998 Volkswagen Golf, Jetta and Corrado with the 2.8L VR6 12-valve (AAA / AFP). It pairs a cast T3 manifold with a hybrid T3/T4 turbo, 35mm external wastegate, front-mount intercooler, stainless dump pipe, boost controller, blow-off valve, oil cooler, turbo timer and fuel-system parts in one box. Most installs keep A/C and power steering, and it works with manual or automatic transmissions. Expect strong gains at a conservative 8–10 psi with a proper tune. The 390+ hp figure is the hardware's ceiling at 20–30 psi with a built engine, fueling and supporting mods, not a dyno result for a stock car.

Exact Fitment — Volkswagen

• 1992–1998 Golf (MK3) 2.8L VR6 12V
• 1992–1998 Jetta (MK3) 2.8L VR6 12V
• 1992–1995 Corrado 2.8L VR6 12V
• VR6 12-valve engines, e.g. AAA / AFP family
• Not for VR6 24V (MK4/MK5 / R32), 1.8T, 2.0L 8V, 1.9L TDI or later 2.0T engines
• Not for Audi / Seat chassis that need a different manifold or intercooler layout — this listing is Volkswagen Golf / Jetta / Corrado only

Not Included

• Chassis-specific downpipe and exhaust beyond the dump pipe
• Larger injectors, fuel pump and ECU tune (required)
• Clutch upgrade, boost gauge and wideband
• Oil-pan return bung if your setup needs one
• Battery relocation kit (not in this package)

Installation Notes

• Professional installation strongly recommended. The intercooler piping is universal, so expect some cutting and fitting
• The manifold is street cast, not equal-length tubular: stronger and more affordable, with a different spool character
• Oil return must drain by gravity; prime the turbo with oil before first start and check for leaks at feed and return
• Blow-off valve flanges are installed at your discretion
• Keep boost around 8–10 psi until fuel and tune are upgraded, and let the turbo timer handle cool-down
• Confirm clearance for the front-mount intercooler and oil cooler during mock-up

FAQs

Does this fit a VR6 24V or R32? No. It is for the 12-valve VR6 (AAA / AFP) in 1992–1998 Golf, Jetta and Corrado only.

How much power will it make? Strong gains at 8–10 psi on a healthy stock engine with a proper tune. 390+ hp is the hardware ceiling at higher boost with a built engine and full supporting mods.

Can I keep A/C and power steering? Most installs keep both; confirm clearance during mock-up.

Manual or automatic? Fits either when the engine matches.

Is it plug-and-play? No. You still need injectors, a fuel pump, an ECU tune and some pipe fitting.
