This kit is designed to work with 02-04 Acura Rsx base model axles which you can pick up at any auto parts store**

**This kit requires you to make clearance onto your passenger side frame rail as shown in my youtube for the water pump, AS WELL AS, small section on the drivers side frame rail to clear the rear corner of the transmission mount**

This kit is purpose-built to support a Honda K-series engine swap into 2002–2006 MINI Cooper vehicles. Every component has been fully redesigned and upgraded to CNC-machined 6061-T6 billet aluminum, delivering the strength, precision, and durability required for high-performance applications.

Paired with 88A polyurethane bushings, this kit provides a firm, controlled drivetrain connection that significantly reduces engine and transmission movement under load. The result is improved throttle response, better power delivery, and increased confidence during aggressive driving—without the harshness of solid mounts.

The switch from steel to billet 6061-T6 aluminum offers several advantages:

Excellent strength-to-weight ratio
Reduced overall mount weight
Increased corrosion resistance
Improved damping of high-frequency vibration
Extremely precise and repeatable fitment

Designed with real-world performance in mind, these mounts are ideal for street-driven swaps, track cars, and motorsport builds where drivetrain control and reliability are critical.

Kit Includes the following:

Engine/Transmission Brackets
Engine/Transmission Mounts
Fuse box Stem
Frame Rail Spacer
Hardware
K series Tucked Engine Wiring Harness
Conversion Harness

Be sure to also add the K swap aluminum oil pan to your order as this is required for the swap to bolt the rear engine mount.

FAQ to the swap:

What Ecu can I use with this kit?

The engine harness is based off a 02-04 Acura Rsx so the simplest ecu to use is a 02-04 Hondata Kpro V3, or V4. You can also use AEM V2 for a 02-04 Rsx. If you get a jumper harness you may run AEM infinity or Fueltech ecu as well. Options are endless.

What Engine can I use with the kit?

K20a2, k20a3, k20z1, k20z3, k24a1, k24a2, k24a4, k24a8

What Transmission do I use?

There are many options when it comes to transmissions, all depends on your goals:

02-04 Honda Civic Si Ep3 (5 speed non LSD)

02-04 Acura Rsx Base model (5 speed non LSD)

02-04 Acura Rsx Type S (6 speed non LSD 4.3 Final Drive)

05-06 Acura Rsx Type S (6 speed Non LSD 4.7 Final Drive)

06-11 Honda Civic Si (6 Speed LSD 4.7 Final Drive)

NOTE: Honda Accord/Acura TSX transmission will not work

What shifter cables and Shifter box do I use?

Shifter box and cables must match transmission. If you are using Rsx or Ep3 Transmission you will use a Rsx style (A2) shifter box & cables. If you are using a 06-11 Civic Si transmission you will use the shifter cables and shifter box for the (Z3) as they work backwards from the Rsx.

NVH Disclaimer-

This mount kit is designed for performance-oriented applications and utilizes 88A polyurethane bushings. As with any performance mount, some increase in noise, vibration, and harshness (NVH) compared to factory rubber mounts may be present.

In most cases, NVH remains reasonable for street-driven vehicles and is primarily noticeable at idle or low engine speeds. Vibration levels can vary depending on factors such as engine condition, tuning, exhaust configuration, and overall vehicle setup.

These mounts are engineered to provide a balanced combination of drivetrain control, durability, and drivability, making them suitable for both street and track use.
