Turbo Kit for Honda S2000 F20 F22 (2000-2009) 2.0L 2.2L AP1 AP2

Complete T3/T4 turbo kit for the 2000–2009 Honda S2000 (AP1 F20C 2.0L and AP2 F22C1 2.2L). Built around a polished 321 stainless tubular manifold, a hybrid T3/T4 turbo, front-mount intercooler, internal wastegate actuator, oil feed/return kit, blow-off valve and a full aluminum intercooler piping set. A tune and fueling upgrades are required, and the S2000-specific downpipe/exhaust connection is not included.

Why this kit

• TIG-welded 321 stainless tubular manifold with large primaries, thick T3 flange, ported and polished
• T3/T4 hybrid turbo: .57 trim compressor, .50 A/R compressor / .63 A/R turbine housings
• Internal wastegate actuator pre-set to 8 psi, bolts straight to the turbine housing
• Front-mount aluminum intercooler with 2.5" hot and cold inlets plus full 2.5" piping kit
• Braided -3AN oil feed, high-temp oil return line, billet adapter plate and blow-off valve kit

Package Includes

• (1) T3/T4 hybrid turbocharger — oil fitting gaskets & mounting studs included
• (1) Stainless tubular turbo manifold (T3 flange) — full install kit with bolts, hardware and gaskets for turbo and exhaust manifold flanges
• (1) Front-mount aluminum intercooler — 2.5" hot and cold inlets
• (1) Internal wastegate kit — pre-set to 8 psi, direct bolt-on to turbine housing, V-band flange and clamp included
• (1) Aluminum intercooler piping kit: (2) 90° 2.5" bends, (2) 60° 2.5" bends, (2) 45° 2.5" bends, (2) straight 2.5" pipes, (2) 2.5" 90° silicone couplers, (6) 2.5" straight silicone couplers, (16) stainless worm-gear clamps
• (1) Turbo oiling kit: -3AN braided stainless oil feed line, 18" 5/8" high-temp 550 psi oil return line, 2 additional fittings for adapting to the engine, CNC billet adapter plate, extra drain and feed gaskets
• (1) Blow-off valve kit with complete install kit

Turbocharger & Manifold Specs

• Turbo: T3/T4 hybrid, wet-float bearings, balanced
• Compressor: .57 trim, .50 A/R housing, 3" bellhorn inlet, 2" outlet
• Turbine: .63 A/R housing, T3 inlet flange
• Oil inlet: 1/8" NPT
• Manifold: 321 stainless, TIG-welded tubular, large primaries, polished finish
• About +100 hp on a healthy stock engine at 8 psi; 450–485+ hp is the marketed hardware ceiling at 25+ psi with a built engine and supporting mods — not a dyno result

Exact Fitment — Honda S2000

• 2000–2003 Honda S2000 AP1 — F20C 2.0L DOHC VTEC
• 2004–2009 Honda S2000 AP2 — F22C1 2.2L DOHC VTEC (Base and 2008–2009 CR)
• Manual transmission (all US S2000s are 6-speed manual)
• Intercooler piping is universal 2.5" aluminum and may need light trimming/modification to fit; verify routing around the radiator, bumper support and A/C lines before final install

Not Included

• S2000-specific downpipe and exhaust beyond the turbo outlet
• Larger fuel injectors, fuel pump, and engine management/tune
• Oil-pan return bung/drain fitting welding
• Upgraded clutch, gauges (boost, AFR, oil pressure)

Installation Notes

• A proper tune with upgraded injectors and fuel pump is required — do not run boost on the stock calibration.
• The oil return must drain by gravity into the pan; most installs need a return bung added to the oil pan.
• Expect to fabricate or adapt a downpipe/exhaust connection and trim intercooler piping.
• Blow-off valve flanges can be installed at the installer's discretion.
• Let the engine idle 30–60 seconds after hard driving so the turbo can cool down.
• The high-revving F20C/F22C uses stock pistons and rods; keep boost conservative on a stock bottom end.
• Professional installation is recommended.

FAQs

Will this fit both AP1 and AP2 S2000s?
Yes — it's listed for 2000–2003 AP1 (F20C 2.0L) and 2004–2009 AP2 (F22C1 2.2L). Piping may need trimming.

How much power will it make?
Around 100 hp over stock at 8 psi on a healthy stock engine with a proper tune. Higher numbers require a built engine, fueling and more boost.

Does it include a downpipe?
No. Plan on a downpipe or custom exhaust connection from the turbine outlet.

Is it plug and play?
No. It needs a tune, fuel upgrades, an oil-pan return fitting and some fabrication.

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