You Can Honda S2000 turbocharger kit

The car was first shown as a concept at the Tokyo Motor Show in 1995, The whole world would have to wait another 4 years to buy it. The S2000 is named for its engine displacement of 2L, carrying on in the tradition of the S500 and S800 roadsters of the 1960s. Honda altered the car's setup multiple times throughout its production to include changes to the chassis, powerplant and crivetrain. There are 2 versions according to the Honda specifications, chassis AP1 was pre '03 and the second designation after. Though cosmetically similar, the AP2 incorporated significant changes to the drivetrain and suspension. The car was discontinued just before the turn of 2010.

The most dramatic change to the second-generation S2000 was the new engine. As the F22's stock engine internals are forged, it can make an incredible amount of horsepower on a turbocharged stock engine block. There are examples runinng the standard block with almost half the power of a Bugatti Veyron!.

Things you'll need:

Turbo intake
Exhaust manifold
Inter- or charge-cooler
Blowoff valve
Oil/coolant lines
A suitable ECU

If you're on a budget, second-hand units can help keep the costs down considerably. There are many models out there from Mitsi 18G's to some of the smaller turbo diesel units to help eliminate the low-mid range gap in the S2000 powerband. Those with the money should certainly not scrimp in this area - always try to get the best, highest-throughput turo that you can afford. Measure your turbocharger's air inlet, and purchase an aftermarket turbo air intake with the same neck diameter to replace the F22's stock intake system.

A tubular manifold from and aftermarket company will really help with the numbers so consider it over a home-made welding job. These can be custom fabricated by an exhaust shop to bolt to the F22 and accept your specific turbocharger. Alternatively, numerous aftermarket exhaust manifolds that mount to various turbochargers are available for the F22.

Charge or intercooler is an often-debated point. A turbo really heats up the air as it's forced throught the turbines so you need this system to safeguard agaiinst pinging and detonation. As the F22 is a high-compression engine, a large, front-mount intercooler system is ideal, as the engine will perform poorly with high intake temperatures. You will need to modify the valance to make it all fit.

Purchase a blowoff valve. These mount to the upper intercooler piping, intended to release excess charged air from the intake track when the throttle is lifted. Dump valves are largely a "one size fits all" solution and will fit most applications.

The turbo will need new oil/water lines dependent on how it is cooled. Putting your own pipes together is easy - just get the lengths you need of stainless braided lines from a local auto factor - the relevant fitting are always available on eBay.

The final and most important step is to get the engine and turbo setup properly mapped, preferably by a professional with a rolling road. For budget setups, a piggyback ECU tuner can be used. Professional dyno tuning for turbocharged F22 engines is important, as a poor engine tune will lead to low horsepower numbers, and possibly engine failure.
