B18 swaps are becoming increasingly popular as people look for ways to increase the power output of their Honda engines. There are a few things you will need in order to complete the swap, which we will outline below.
First and foremost, you will need an engine. A B18 engine can be sourced from a number of places, including salvage yards or online retailers. You will also need a transmission that is compatible with the B18 engine. The most common transmission to use for this swap is the B-series 5-speed manual, although some people do use the 6-speed manual or even the automatic transmissions.
Once you have your engine and transmission, you will need to source a few other parts to complete the swap. These parts include an ECU (Engine Control Unit), wiring harness, clutch kit, mount kit, and header. All of these parts can be sourced from aftermarket suppliers or through salvage yards.
The last thing you will need before starting your B18 swap is a shop manual. This will walk you through all of the steps necessary to complete the swap correctly. Once you have all of your parts and your shop manual, you should be able to complete the swap relatively easily!
