what about for those who own a gen2?
will this fit? ie: GC8 intercoolers for those with single setups

Im pretty sure the 385,155,115 intercooler will fit on the b4 but the larger 510,200,113 intercooler is way too big and will hit on the primary turbo. I have fitted the larger of the two intercoolers to two gc8 wrx's and these needed substantial mods to fit including relocating the clutch master cylinder reservoir, making new intercooler mount brackets and modifying the firewall structure. I can take photos and give measurements of two similar intercoolers I have at my work that have come from china but are pretty good quality and will try and fit the smaller of the two onto my car.

Hyperflow FTMFW!

Most WRX/STI TMIC's will fit onto a B4. The only difference is te plumbing from the turbo's

a WRX Y-pipe and Stock BOV will fit onto a B4 top mount as if it was ment to be there.

Has any one on here got one of these hyper flow coolers on their car? Do they still get heat soak issues? would a front mount be better or are these top mounts ideal?

Mate, a bit behind but I have a hyperflow unit, and I found it in conjuction with an ECU reset to be a great investment. The car runs a lot better and smoother and the performance is a lot more consistent now. Its definately a worth while investment if your not planning on going mental with your mods. I weighed up a front mount and with all the chopping and intricate work to install a FMIC (including cutting up the crash bar) opted for the Top mount instead.

Hope this helps

Anyone got an intercooler mist spray kit and care to discuss how they installed it. There was another member who came on the melbourne cruise a few months back who had a really good mist spray setup to avoid heat build up.
