- Well ethanol definitely helps with that and also helpful when you are running still that stock F20C with a compression ratio designed for a naturally aspirated engine, you've added boost so yeah the ethanol's definitely going to be helpful there, making sure the engine's going to run reliably. Your F20C or F22C engine is seriously strong, but over 400 whp means you should get your engine properly built. <<<<< with some good tuning, that should net me around 500whp on pump gas. Turbo This F20C engine is good for boost, and can withstand high loads. To get 300 HP, you only have to buy a supercharger kit, and install it on stock internals. Anything more than this is going to need some internal engine modifications. I just wanted to see what turbo setups guys had on internally stock k20's. they have made as much as 700hp bone stock, even the intake manifold and tb! The Honda S2000 can handle up to 400+ whp on stock internals and with the right tuning, you can push it to 600 whp. Again, that's with a stock intake manifold still. An F20C with intake/header/exhaust and tuning (stock cams, stock cam gears, stock intake manifold) will make 250 whp/165 lbs-ft. Note that compression will increase by about .5 (8.5:1 = 9.0:1) in the 2.2 engine. Stock internals be damned, the 5.3 had come to party. Pretty soon I wont be stock internals any more Im going with vitaras and rcautoworks custom length rods. It all depends on your driving style to go with forged internals or not. actually, because the internals on the f20’s are forged, they handle boost nicely. The 2002 was available with a variety of powerplants over the years, including a 170 hp turbo 2.0-liter. As the practice F20C/S2000 Pistons (Forged) For the most part, all F20C pistons (S2000) fit the new F22C engines. that way i can extract all available hp from the engine. Instead of having a thread Titled how much power can a stock k20/a2/z3/z1 make, I thought i would make this thread. I've turbo charged a few cars and stock internals don't like a whole lot of boost. FA20 stock internals keep more than 500 WHP, and if you use sports fuel and adjust ECU correctly, than over 600 horsepower. The F20C and F22C1 were inline-4 engines produced by Honda for use in the Honda S2000.They are one of the few Honda 4-cylinder automobile engines that are designed to sit longitudinally for rear wheel drive.. Throw in cams (Hytech makes a great set) and adjustable cam gears and it will make 270 whp and 175-180 lbs-ft of torque without i-VTEC. 400+ horsepower can be added to S2000 with the use of a turbokit that can also be installed on stock pistons. i plan on running 1 bar on my gt35r with stock internals. Future Shock. The plan is stock head, IN900cc injectors, ebay 50 trim and 20psi boost. Such kit is possible to install on stock internals and to receive 400 ++ WHP, and even up to 500 WHP (sport fuel). The 1,000hp mark was eclipsed, followed soon by 1,100 hp and then, finally, the peak power of the night, an amazing 1,203 hp at 26.8 psi! But those vintage motors look rather archaic compared to the mighty F20C, an all-aluminum masterpiece with forged internals and sky-high redline. Instead of supercharger kit, you can install turbo kit on the basis of Garrett GTX3076R. The plan is stock head, IN900cc injectors, ebay 50 trim and 20psi boost. These engines are a distant relative to the F-series engines found in the mid-1990s Honda Accord and Prelude. Me i would replace the internals first since the f20c runs a high compression ratio.
