What year did the liquid intercooler come in?
Thanks.

US market cars, '76 to '79, had thermal reactors. They are cylindrical, running lengthwise, just beneath the exhaust ports. The ROW Turbos, and the US market Turbos after '86, have heat exchangers that look exactly like the heat exchangers on SCs and Carreras. The thermal reactors lead to bad exhaust flow and excessive heat. They're truly an abomination, especially on a beautiful car like a 930.
