HeetSheet fits 1968
1/2 to '89 911 engines using factory exhaust
systems and aftermarket replacement heat
exchangers. These engines have a lower valve cover
with 11 attachment nuts. Order
Model No. HS-1.
HeetSheets will fit on '75-77 911's equipped with
factory thermal reactors with slight modifications.
Contact us for details.
HeetSheets will fit on '76-89 Turbos.
Due to space restrictions, you should verify fit on
engines using aftermarket racing exhaust headers.
See "Rule of Thumb Fitment" below.
HeetSheet has been tested and is compatible with
heat exchangers manufactured by SSI.
HeetSheets may not fit all 914-6s. Due to the tight
clearance between the engine and chassis, the
engine must be exactly centered. This installation
seems to be most successful on modified 914s with a
911 engine conversion.
HeetSheets for Porsche 993. Coming
soon. Contact
us and we'll let you know when this happens.
All 911 engine applications:
HeetSheet requires approximately 1.25" (32mm) of
clear space in front of the lower valve cover.
HeetSheets will fit if this minimum space is
available.
