NEW as of Summer 2022: Our Version 3 K24Z3 Ultimate Package includes the following changes:

-Updated oil pan and pump housing, and pickup design

-Both cable and Drive-By-Wire throttle body options are now available

-The Kpro wiring conversion harness has been removed from this package to make room for new wiring solutions, including Haltech

-The cast timing chain cover has been removed, but can be added to your order here (Kpro users only).

The Ultimate K24Z3 Swap Package is designed to give customers the parts they need to complete the most straightforward swap in a 1990-2005 Miata using all of the proven components in our K24Z3 test car.

This package includes:

-K series to Miata transmission adapter plate

-K series to Miata flywheel

-Machined engine mounts

-Engine mount pads

-Baffled aluminum oil pan with pickup tube

-KMiata K20 oil pump adapter

-Hydraulic clutch release bearing with clutch lines (5 or 6-speed)

-Wilwood ¾" master cylinder kit

-KPower RWD intake manifold

-Intake manifold gasket and hardware

-K24Z3 upper coolant neck

-Slim flywheel dust cover

-Serpentine belt

-3" downpipe with flex

-74mm cable throttle body with billet cable wheel, Acuity TPS, and TPS adapter

OR

-Bosch 74mm Drive-by-Wire throttle body and adapter with gaskets

Notes:

1) in order for this package to fit, a K20 Type S oil pump must be installed. Although a number of options are available for this upgrade, we recommend our K20 Type S oil pump package found here.

2) We now only recommend pairing this bearing to the Exedy Stage 1 clutch. Exedy holds extremely tight tolerances for pressure plate height, which is important for reliable operation of this unit.

3) The K24Z7 engine is identical to the K24Z3, and can be used with this swap package.
