i heard about the yellow valve covers in an issue of sport comact car. i think it was one of their first installments of "Hybrid-How-To". it was an h22 swap into a 5th gen civic.
they said avoid the h22 w/ ATTS at all costs, cause i think the wiring is beyond hellish, and its just easier to use a non-ATTS tranny, and non-ATTS ecu.
