So, i finally gave in and picked up a radiator from @SubaruPartsGirl As always Jackie was super helpful and quick to respond.But, choosing to go with a performance radiator leaves me with a slew of questions. I've read some of the threads regarding installation of the Mishimoto and Koyorad radiators, but i'm still torn on a lot of things.My biggest two questions right now are regarding the Transmission Cooler and a Radiator Cap.So, starting with the transmission cooler, it seems like most members tend to go with B&M SuperCooler part #70255 . I was also looking at the Mishimoto MMTC-U kit, but i don't really see any one using them in the threads i've been reading. Has anyone had any experience with the Mishimoto one? So far the most helpful thread/post has been @SuperRu 's post here The radiator cap issue is also throwing me off. In 06-08, there's two caps i believe, one on the radiator and one on the expansion tank. I've read a number of threads that indicate that the two caps have different pressure ratings, but other members will chime in and disagree. @2.5x_sleeper mentioned that his two caps had different ratings, if i remember correctly. So, that being said, i've been warned against using the cap that came with the radiator, and i don't have a replacement one that i'm aware of. So, for a replacement, there are a ton of choices ranging greatly in price. I wouldn't mind paying a little bit more for a fancy looking one, but, what should the pressure rating on it be? Should it be the same as the cap on the expansion tank? Greater pressure? Lower pressure? I'm at a bit of a loss on this one. One thread there was debate on whether or not greater pressure would hurt the head gasket, so there's that. I don't have any real need for the pressure to be different than what the factory has it set to i suppose, but then, what's that?Anyways, i'm not in a real rush for this project, especially since it's cold out. Hopefully my current radiator won't give up the ghost. But this is all preemptive anyways (hopefully).
