Engine swap
From Wikipedia, the free encyclopedia
An engine swap is the process of removing a car's engine and replacing it with another; this is done either because of failure, or to install a different engine, usually one that is more powerful or more up to date and maintainable.
While one can work wonders with engine tuning to achieve greater power, the same techniques applied to a better engine are unlikely to be much more expensive and may be much more rewarding.
An engine swap can either be to another engine intended to work in the car by the manufacturer, or one totally different. The former is much simpler than the latter, of course. To fit an engine the car was never intended to take may require much work -- modifying the car to fit the engine, modifying the engine to fit the car, and building such things as custom engine mounts to interface them.
A common anecdote among tuners is that the easiest way to make a car faster is to drop in a Corvette engine or a small block 350 and be done with it. Other popular engine swaps are putting a Porsche engine in a VW Beetle or a turbocharged engine from a Saab 900 in a Saab 99 or BMW[1].
In the world of sport compact enthusiasts, engine swaps are common with Nissans and Hondas. A stock US Spec Nissan 240SX produces 160 hp in stock form with its torquey KA24DE 160 hp engine. Swapped out with a Japanese SR20DET, a Nissan 240SX will produce over 200 hp right out of the box, with mild modifications that can increase power anywhere from 250 hp to 300 hp.
In the Honda world, popular engine swaps include the Civic Si (B16A), Integra GSR(B18C), and the Integra Type R (B18C5) engines. Swapping it into a 88-00 lighter Honda Civic chassis, greater performance can be achievable. Not for the novices, other high-powered and less common swaps include the RSX Type S (K20A), and the Prelude (H22A) engine swap.
Engine swaps are also somewhat common within the Volkswagen tuning scene, often placing Mark III and Mark IV engines such as the VR6 and the 1.8 T into the Mark II GTI, Jetta and Corrado. Less common is the swap into a Mark 1 Rabbit or Cabriolet, giving an amazing power to weight ratio even with minimally modified powerplants.ja:エンジンスワップ
