Top Ten JDM Engine Swaps

It's hard to mention talk about any aspect of import or Japanese sports car performance without discussing JDM engine swaps. JDM stands for Japanese Domestic Market and it's a great source for engines and transmissions to swap into your import vehicle. Whereas many of the incredible Japanese supercars and engines made their mark in the 80s and 90s, these unfortunately never made it to US shores. JDM engine swaps are easier than ever with the ever increasing choices of JDM engine importers out there.

Many of these importing companies have a large selection and inventory. Being able to pick out the best engine or transmission of choice is great, whether you are modifying your car or just repairing it. Because these are used components, it can really be a much cheaper alternative than buying a new engine, shortblock or transmission from your dealer. If you are modifying your car these JDM engine swaps can really give you a far better base for modifications than your factory engine ever could.

If you are in the market for an replacement engine or transmission, here's 10 of the most popular and best JDM engine swaps out there for you to choose from.


Honda K series JDM Engine

Honda K series JDM Engine

The new i-VTEC K series engine is reached a point where it's become an incredible choice for engine swappers. Honda enthusiasts who are tired of the same old DOHC B series engine, have gone with the engine from the RSX. Six speed transmission and a 2.0 or 2.4 liter displacement is available with intelligent VTEC controls.

Lots of aftermarket support and modifications give you plenty of options. It's still relatively expensive to swap and difficult to source a six speed transmission, but it's a great JDM engine swap to start this countdown.
