I've been looking at underdrive pulley kits for my 7AFE and there not too expensive considering that it would be and easy power gain. Just wondering if anybodies running the underdrive pulley setup and if there was any noticable difference?

NST sells them, google up "non stop tuning".

AFAIK, you would be the first, if not one of the first to have these if you do decide to buy them.

I was going to get one of those when I swapped in a 4agze.... but I never heard of one for the 7afe. Let us know how it goes!!!!

Yah the kits is about $250 for a decent quality one, but thats a nice chunk of cash for what could be little or no power gain. But if anyone out there can prove me wrong, please do!

More waste of money and further it can kill your crank after a while.

Just so you know I'm not just putting up a random opinion.

yep! even though it does add more hp, I'd say only get a newer harmonic balancer as a replacement when you do a timing/fan belt change. Doing a pulley swap should be for high performance cars not economy cars!
