The Grannas Racing cast aluminum bellhousing for 2JZ/1JZ to T56 or T56 Magnum is designed with performance street cars in mind. Budget friendly, easy to install, high quality, heavy duty, precision machined, and better at noise cancelling than a steel bellhousing. These come with all hardware required for install.
These bell housings also come standard in all my GR700A kits (A for Aluminum bell).
Without the need for an index plate or offset dowels, these bellhousings are much more affordable than other options. They are heavy wall aluminum, which will dampen clutch and engine noise much better than the steel counterparts.
These bells feature a service window which is super beneficial if you need to adjust a hydraulic release bearing. Previously this would not be possible without removal of the transmission.
These bells are precision machined so there should not be any need to do any sort of offset dowel pins to get them within the .005" spec suggested for a performance T56 application.
I have all the machine work done in the USA, for precision, accuracy and the ability to easily make changes if need be. I have checked these on four different bone stock 2JZ engines and all of them land under .005 tolerance range.
Note: If you have had engine work, like billet main caps, you may want to consider checking runout with an index plate. When your machine shop line bores the mains it can move the crank position slightly upward and could effect index. These will work with GM based TR6060 transmissions as well.
