At what point do you swap out the stock intercooler? Does the stock intercooler have any weak points?

Aside from style, aren't front mounts a bad idea, especially when you have a nice hood scoop on top? I remember with the RX-7, it was tight and the front mounts would block air from the radiator.

On the stock turbo the stock intercooler is sufficient and reliable. A cheap way to avoid heat soak in stop/go traffic is to tilt the unit using washers on its mounting bolts (search DIY thread) but then again, if it's stop/go traffic heat soak may make no difference anyway.

Front mounts allow more volume but they also generally require some creative dentistry. I don't know of anyone that's looked at coolant temperatures with a front vs. a top mount, but for what it's worth the works cars use a reversed intake, facing forward, feeding a slanted front mount. In this setup, the radiator and the intercooler form a "V."

The Rx-7's had issues with overheating on the third gen models. This is mostly due to the sequential turbo setup of the car and the requirement of catalysts in the US. So, blocking the radiator was a bad idea. WRXs do not have heating problems so a front mount would be the optimum position for cooling the intake charge. The main difference between the the two setups(top mount and front mount) is the difference in distance from the compressor outlet, topmounts tend to spool a little faster due to the shorter distance the intake charge has to travel.
