JZ to 350Z/370Z Adapter Plate Instructions
JZ to 350Z/370Z
Thank you for purchasing the Collins adapters 2JZ/1JZ to 350Z/370Z/VQ transmission adapter plate. If you purchased just the adapter plate without the flywheel and are looking to get the pilot bearing adapter or flywheel that is required, you can find it on www.collinsperformancetechnologies.com under the adaptation components tab. We also offer the flywheel for this swap.
This is a guide of things you should do so the engine and transmission go together smoothly:
1. You should purchase the proper transmission bolts from any hardware store that sells metric bolts. If you are using the 350Z CD001-CD009 offered in model years 2003-2006 (with the external slave cylinder), you need (5) M12x1.75 55mm hex head cap screws with (3) M10x1.5 35mm hex head cap screws. If you are using the 350ZHR/370Z JK40C-JK40B offered in model years 2007-Current (with the internal concentric slave cylinder) you need (4) M12x1.75 55mm hex head cap screws with (2) M10x1.5 35mm hex head cap screws, this is because there is multiple interfaces with the 350Z bolt pattern. With the 370Z transmission, you will have to drill out the transmission holes in order to get proper fitment of the bolts.
2. The starter you should use should be out of a 2JZ-GE-GTE motor that has an open face to. This will prevent you from having to remove excess material on the transmission to get the starter to recess into the transmission side. If you want to retain your stock starter, you must take a chunk of your 350Z/370Z transmission where the starter sticks out.
3. You must drill out the starter’s tapped holes where the original fasteners thread into the adapter plate. Use a 15/32’’ drill bit to drill out the threads. This is so that the studs that are supplied with the package can pass through the starter if you need to remove the starter with the transmission still in the vehicle.
4. Use red Loctite 242 on all of the threads used in this conversion.
5. Fasten the adapter plate to the engine using the supplied fasteners, noting that the lower right hand side of the oil pan, there will be a socket head cap screw that works with certain engines that may not be located on your specific engine.
6. After you get the adapter plate fastened to the engine, place the starter on the motor and place the short threaded side of the stud going through the starter into the adapter plate.
7. If you ordered the adapter and flywheel combo, torque the flywheel bolts to 56ftlbs in a stepped format using 20ftlb increments. Red Loctite on the threads. If you have any questions, do not hesitate to call—it’s what we are here for! (803) SWAP-1UZ
