so right now im running only 1 14" mishimoto pusher fan that came with my radiator and it doesnt do a very good job of cooling, especially for cruising with a lot of stops. im looking to buy a new dual efan pusher setup and just wondering what u guys are running and what models fit best and cool the best.

without sounding like a jerk, you should search for this one. There are two excellent writeups about this. One did a comparison of 3 different common cooling fan setups, compared temps over different driving conditions, etc. The other is the "My car is overheating..." thread. Both have great info. Good luck!

I'm getting a new koyo today which i plan on pairing with the FAL 12" low profile puller fans. I know I know it doesn't fit but I will be cutting into the radiator support about 2'' and shaving down some of the fan shroud and removing those damn FAL covers. That should give me enough clearance although i'm welding on two more brackets to the remaining radiator support the strengthen the hood latch. Dont want that getting messed up. A friend in miami did this to his and it cleared with the r33 xmember so I should be okay.

Dual FAL and Koyo always works for me.

I went to my local junk yard and got a dual fan setup off a Maxima, You gotta modify the Shrouds just slightly, But it seems to be working great as a pusher setup and only costed me 20$ That will be your cheapest setup.
