Who makes a kit, how much does it cost, where on the internet is it sold, and can the electric fan from the first gen be made to fit the 2nd gen?

Keep your stock fan it rocks and is not worth the aggrevation to replace for that extra 2-4 rwhp.

The electric fans do not work as well as the stock belt fan. I know 2 poeple now that wastd their money on electric and ended up putting back in the stock one.

If you must - Summit racing sells a dual 11" electric fan maade by a company called Be Cool. It works really well anf fits the stock radiator perfectly. It costs about $290.

I run the Perma-cool fan. Not by choice, but by necessity. I dont have a fan shroud made for my K2RD radiator.

what about those pusher/puller fans? can you use one of those by themself or would it not be efficient enough?

You'd definately want a puller fan if you are even going e-fan. The only reason I can tell to go e-fan is to make some room in the engine bay. Power gains are negligible.
