2JZ SFI Approved Billet Flywheel and Mid-Plate Adapter for Chevy Trans.
Width of plate is 28-3/8"... Center Bolt Hole to Center Bolt Hole Measures 27-1/2"
This ATF 1JZ/2JZ Mid-Plate Adapter Kit comes with our SFI Approved Billet Aluminum Flexplate with both Large and Small Bolt Patterns for the Torque Converter. ARP Flexplate Hardware, Starter Shim and a Mid-Plate Adapter.
The Mid-Plate Adapter is like our standard 1JZ/2JZ Adapter plate expect this plate allows you to tie it to the chassis like a true Mid-plate racers use to stabilize the engine more steadily in place instead of motor mounts. Also helps solidify the chassis. Best if combined with a Front Plate as an option. The Midplate measures 28-3/8" Wide and measure 27-1/2" Center to Center bolt holes.
Front and Midplates help engine longevity and prevent twisting of the engine block. We`ve seen over the years that the JZ engines start to have engine block failures near the 1200 whp mark. It also prevents cylinder bores from becoming oblong from being pulled on either side of the engine block, which will cause piston to wall clearance issues..
