I know I'm late to the party, by about three years. But, I think it needs to be said, this post was not very informative. I visited the thread for some insight, and I left with nothing. I'm not blasting the post just to be a dick, I was truly looking for information.
The instructions were good. Now the job doesn't seem so intimidating but, you didn't provide a single part number, website or phone number; at least that I could see. I can't see the pics, so maybe that info was covered.
There was no real world data, either before, or after the swap. But, you swear the car was better.
You changed the size of the pulley, how did that affect your RPMs? Is a re-tune necessary? What was the cost for parts? And so on.
I think this is a classic case of slapping on a mod and giving good reviews without any actual data. Much like a kid cuts his springs and claims the car corners better.
