The ‘I4′ DOHC engine first introduced in the Ford Sierra and Granada models of late 1989 was only available in the Sierra in 2.0-litre 8-valve form. While power output improvements can be made to the stock 2.0 8v engine, as documented in a separate article entitled ‘DOHC tuning’ and available from http://www.crustworld.co.uk/sierra/dohctuning.pdf, the engine output is ultimately limited by the availability and cost-effectiveness of off-the-shelf tuning parts.

The s14 200sx seems to have been designed and marketed not as an out-and-out sports car, but as a sporty car with suitability for the company-car market. With this in mind, the air intake and the exhaust are quite restrictive, making the car more refined. Removing these restrictions will unleash a good few horsepower just by allowing the engine to do its job unfettered, and as such, may even increase the fuel Read the rest of this entry »

While simple in principle, the S-Flo for the 2.7l twin turbo produces quite tangible increases in engine power and smoothness. The improvements are from a combination of air filter design (the unique venturi shaped base of the ITG filter) and the precise mandrel bent transition tube. Our scan tool measurements recorded an average increase of 25 grams-per-second of air through the mass air flow sensor (MAF), with a dramatically smoother flow curve. We believe you will be quite pleased with the S-Flo. Thank you for your purchase!
