Honda K-Series to Subaru EJ Transmission
Honda K-Series to Subaru EJ Transmission
Looking to get big, cheap, reliable and easy power in your Subaru? Are you as sick of spinning rod bearings, broken ring lands and head gaskets as we are?!?
Performance adapters introduces the perfect solution!
Ditch your flat 4 and replace it with a Honda K-Series. Not only will you have Honda reliability but you'll be able to make bigger power much easier than you would with that old EJ.
We do make this kit for the NON-STI transmissions. The flywheel is different than the STI please double check your selection. However, the XT/WRX transmissions are not recommended for anything beyond stock HP. As many of you have heard the XT/WRX transmissions "are made of glass." This isn't exactly true. What is true is that these transmissions lack the case bracing like the STI transmissions. So, when the XT/WRX transmission is subjected to shock loads (launches or burnouts) the case flexes and binds the center diff and destroys the whole transmission. SO, using a K-series with that XT/WRX transmission please consider all future goals/plans. If you do end up buying an STI driveline in the future we do offer just the flywheels. (please call to order)
We have RWD/AWD engine mounting kits that can be added to your order. When Purchased with a kit you will receive a 25 dollar discount off of the mounts.
What makes this kit so great is that we do not use a crank spacer/adapter eliminating a potential failure point. Our flywheel will bolt directly to the K-Series crank with using OEM crank bolts provided in the kit. Secondly we have designed this kit to work with either a single disc OEM style clutch or if you're shooting for a moon tune and need some extra holding power a 7.25" multi disc clutch (Competition Clutch or Action Clutch). This kit retains the OEM Subaru starter as we have made the flywheel work with the original Subaru starter.
We have also incorporated mounting holes on the outside of the adapter plates giving you the option to use the adapter plate as a mid-plate. With the three 12mm clearance holes you will have plenty of options and plenty of strength for your application.
Also included in your kit is two sub-frame spacers helping to give the engine clearance and minimally impacting suspension angles. This also helps to keep the engine lower in the bay.
Lastly, our flywheel is designed to be re-built if needed. Instead of resurfacing the old face we will sell you a replacement. Swapping them takes roughly 30 minutes with the flywheel out and proper tools.
What's included in the kit:
Adapter Plate
Sub-frame Spacers
Flywheel fully assembled with pilot bearing
Hardware kit to bolt everything together
