None to speak of so far, but only have 13,xxx miles on it, so I wouldn't really expect anything.

Have two...no issues.

Injector issues were early 08's...with serial number on the injector starting with 72xxxxx.

Mine sounds like a sewing machine between 1800-2200 rpms and it tried to kill me a few times before I got rid of the rock-hard Sport Cups, but other than that it's been wonderful.

Do a search on the vca site or reach out to Mark J @ Woodhouse of Dan at SPT. Some had issues with one/two of the cylinders. For tracking you need to install a catch can as oil will get into the intake, mix with the fuel and cause detonation issues.
