Honda B18 Swapped Mini

 

Ground up chassis and engine harness completed on this nuts Mini with a Honda B18 engine installed.

The car had various issues, so our friends @tdinorth passed it along to us to sort out. They’d already sorted the mechanical side, and it was decided that replacing all the wiring was needed.
Installation included:

Brand new fusebox, using high quality automotive cable protected by braided sheath.

Custom 3D printed centre mount.

@link_ecu Atom ECU

Brand new engine harness in braided sheath.

COP conversion using our own install plate and parts.

Brand new battery and power cables including our new carbon bulkhead mount.

When utilising just a crank sensor on COP conversions we usually have to use wasted spark ignition. After consultation with Link and @king_tuna1 it was decided we’d use a great feature of the Link Atom which is their virtual cam sync. By installing a map sensor into trumpet number 1 the ECU is able to sense barometric change on the cylinder, and uses that information to work out the position of cylinder 1. Once the sync is locked even changes in butterfly position don’t effect it, as the rest is worked out by crank sensor rotation.
An innovative way to get fully sequential ignition without a cam sensor, and worked really well once it was set up.

It will only work with ITBS, but would be a great solution for Clio’s, B Series and Peugeot’s that are being swapped onto bodies.

A lot of our own newly designed parts were used on this build, and really pleased how it all came together
