The Kit Will Fit All EJ20 Crank Cases With A Rear Position 5 Thrust Bearing Classic Or Bug Eye Versions Including The AVCS And Spec C

If You Are Building A Closed Deck Motor For Its Strength And Reliability Then This Kit Would Be A Great Choice But You Will Need To Ensure The Piston Skirts And Oil Jets Have Plenty Of Clearance And Also The Cases Need To Have Been Converted To A Rear Thrust Type Main Bearing

Please Note That Because Of The Extra Throw On The Crankshaft Some Cases But Mainly The Closed Deck Type May Need To Be Modified To Clear The Con-rods As They Rotate To And From TDC

The Bore Clearance Will Need To Machined Or Honed To Suit The Required Bhp And Basic Instructions Are Included

The Compression Ratio Will Need To Be Calculated Which Again Is Relevant To Bhp And Fuel Quality
The Ratio Can Easily Be Adjusted With The Head Gaskets Which Start From 0.6mm Upto 1.6mm With 93mm Bore Eyelets

If You Are Not Able To Carry Out All Of The Above We Would Be Happy To Help With Any Technical Advice And Carry Out Any Machining Work For You

Please State At Checkout Which Size Pistons You Require 92.5mm Or 93.0mm
