The flywheel housing bolts to the original Toyota bell housing has been designed to space the engine away from the firewall in order 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 gearbox, or tail shaft modifications are required.
The 3.8Ltr V6 engine bolt pattern is illustrated below.
The clutch is coupled to the gearbox by a special gearbox input extension shaft. It has the GM spigot diameter with external spline on the engine end and Toyota spigot diameter with 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 4Runner. The extension carrier is also supported by the new bell housing.
The original Toyota 4Runner V6 radiator is large enough to keep the Commodore engine cool.
The factory Commodore sump will not clear the front suspension. The sump will need to be modified to clear.
