AE86 Tech #86-15: Cheap pressure

Heating issues were never much of a problem with me. From mild 4A's to hotter 7A's it's rare to have heating issues. Even the current turbo setup I rarely had any heating issues. Which is a good thing since I'm not one to spend for a the high pressure TRD radiator cap. Here's a cheaper alternative. It's a 16lb/ 1.1 bar cap from Stant that works on corolla radiator. For comparison, the stock cap comes in at a measly 13lb/ .9 bar to you foreigners, and the TRD is rated at 18 psi/ 1.3 bar.

Keep in mind before you start adding high pressure caps, make sure that the rest of the system is up to par in holding down the pressure. Let's keep radiator and or hose pressure failures due to the extra pressure to a minimum.
