Bell Housing Adaptor Kit to suit Commodore V6 to Toyota Hilux Gearbox (R150F, R151F 5-speed manual)

The bell housing has been designed to space the engine away from the firewall to clear the throttle body at the rear of the V6 engine. The original 5-speed is not moved; therefore, no firewall modifications, repositioning of the gearbox, or tail shaft modifications are required.

The clutch is coupled to the gearbox by a special gearbox input extension shaft. It has the GM spigot diameter with an external spline on the engine end and Toyota spigot diameter with an internal spline on the gearbox end. The new input shaft allows the standard V6 GM clutch pressure plate with a V8 clutch disc to be used on the V6 flywheel. The V8 clutch disc provides less clutch shudder due to the clutch plate having stronger centre springs.

The thrust bearing and extension carrier supplied in the kit slides over the gearbox nose cone and will allow the Bundera petrol or diesel 4-cylinder clutch fork to be used with the new pivot supplied in the kit. The new bell housing also supports the extension carrier.

When replacing the Toyota petrol engine, a diesel model slave cylinder will need to be purchased.

Commodore V6 Engine Requirements

You will need to obtain the following components. The Commodore V6 engine is complete with the main engine wiring harness, the ECM computer and mem-cal. Other accessories include the map sensor, purge canister, air cleaner and ducting, air conditioning compressor and power steering pump, engine pipes and catalytic converter, external fuel pump and damper.

If you purchase an auto engine and plan on using it with this kit, we can supply a manual flywheel used in conjunction with the original auto flex plate. The auto starter will need to be changed for the manual Delco Remy starter on VN and VP models.

The engine should also have the driver side engine mount rubber and bracket.
