XATRacing.com is now offering a 2JZGTE (also fits 2JZ-GE) torque plate for those that want to properly hone the cylinders on the 2JZ-GTE engine. It also fits the 2JZGE non-turbo blocks, as well as the 1JZGTE motors.
Any serious engine builder will tell you, especially given the length of the inline 6 engine, that you need a torque plate in order to provide a similar stress pattern on the block that it experiences with the head on the block.
Some builders even go as far as putting an old head gasket between the block and plate, then go through a standard Toyota pattern for torquing down the bolts.
This is a precision machined torque plate, manufactured out of 2.0" (50.8mm) thick 6061 T6 aluminum (precision CNC'd by a large aerospace machine shop). Aluminum is chose as it best replicates stress and strain coefficients of expansion during torquing that the factory aluminum head does.
It has an overbore that will allow for the largest hone/bore possible, so if you are building a stock bore or big bore, it isn't an issue.
The bolt through-holes are clearanced for 1/2" (.500") head studs, which allows you the flexibility to run a factory diameter or 1/2" diameter head stud, all according to the factory head stud location. It is shipped in a sturdy container for protection.
People charge up to $800 for these units, so we thought we can do it better and for less.
You can expect it to ship next day typically, as we have one on the shelf at all times!
These are available for shipment outside the USA if required. Please email firstname.lastname@example.org for a freight quote.
A torque or honing plate is critical when doing the hone/bore process on any 2JZ engine build, especially those that will be running 30psi+ of boost and those running ARP head studs. Performance studs are typically torqued at much higher values than standard OEM studs, which causes a deflection in the cylinders if not using a torque plate.
Machining Note: Prior to the machining process the torque plate should be secured to the block using the same amount of torque you intend to apply during final assembly of the head to the block. We are also offering a rental service to use the ARP head studs that can be shipped with the plate. If you go this option, you will also be charged $15 weekly to rent them, which we will subtract from the deposit once it is returned to us
