I wouldn't deal with a 22RTE. To make them run good, you need very deep pockets. Several of the guys on here have spent many of hours, and money getting a 22RTE to run effectively. If at all, only to take it in the shorts just to get rid of their money pit. Just go to
www.22RTE.com and do some reading.
A good 22RE with a Enginebuilder head with oversized valves, cam, a clean intake, and the larger exhaust, will be more reliable and cheaper than the turbo setup.
