Has anyone upgraded or "souped up" the AC blower on their car? I have an '89 Civic Hatchback with the D15b2 motor. The AC blower is drastically under powered. Theres nothing wrong with it, I know that for a fact. Its just not strong enough for my liking. I dont care about the level of custom work thats involved. I need something stronger. I'm wondering if theres a kit or a good DIY write up. Any suggestions are much appreciated.
