Willing to buy either. Prefer QSD. Not willing to pay over retail or I'd just buy it from the manufacturer.

PM with what you've got.

 

From reading a bunch of old threads both kits are "fine."

QSD appears to have a longer wait time, but better customer service, and you can use any flywheel/clutch you want. The evo kit appears to have problems with certain pressure plates.

QSD retains b-series transmission placement but if you have an integra or an EG you might need to do some work to get the hood to work.

The QSD also doesn't come with mounts or a flywheel if you're planning on going aftermarket. The price difference could be summed up in the cost of mounts and the flywheel that the evo kit comes with.

However with the QSD kit you get choices, any b-series mounts will work and you can pick the flywheel and clutch of your choice without worrying about the shifting issues that the Evo kit has tended to have with certain clutches.
