Bryce started with a 4-cylinder car. In switching to the SHO rather than a standard 3.0 Vulcan, he had to transplant the ECM, harness, etc anyways. The differences between the 4- & 6-cylinder cars are the trans (different bellhousing & mounts), the ECM, and wiring. One Michigan member put a SHO trans in his '92 Tempo GLS (rare V6 sport model), the gear spacing & final drive ratio are much better.
Thanks, and no webpage yet. There is a thread on the tempotopaz.com forums "Performance Modifications" section, "Project S/C, Re-revisited", that details the latter part of the job. Unfortunately, two threads displaying the project from its beginning were lost when the site was revamped.

I'll set up a Cardo site or something, I guess.
