These elements are vital for future modifications and represent the cheapest methods of extracting more power from the car's engine.Īnd best yet, you can expect a power improvement of 20-25% PLUS an improvement in fuel economy. Stage 1 Kits usually consists of a new exhaust, LCB exhaust manifold, intake manifold, performance air filter and replacement carburetor needle, and is available for all engine sizes. This method has the advantages that the engine is all-standard and there is no need to dismantle it for its camshaft and cylinder head.īut sometimes, it is not practical to swap an entire engine and if you already have a good 1275cc engine installed, consider this instead.

If you have a small-engine Mini, consider replacing it with a larger car engine as your first step towards more power, as a larger engine is a better base for future modifications. However, they are noisier and vibrate more than the smaller engines. Their 1275cc engines are usually cheaper than smaller motors with extensive modifications plus they are more tractable when giving the same amount of power. The cheapest way to add more power is to add more cc's. Improving your BHP - Standard Engine Swaps Differences in camshaft, cylinder heads and carburation account for the differing bhp figures for motors of the same capacity. Some car engine configurations are lumped together such as the 1300GT and Cooper S, despite the engines not being exactly the same.

There are other configurations, such as the 997cc Cooper and the 970cc and 1071cc Cooper S, that are not mentioned as these are too expensive and rare to be used to boost the performance of other Minis. Harder to install, "Mini Turbo" has a certain ring to it. These engines are a great starting point for building a Killer Engine!
