VERY RARE GENUINE 3.0 RSR SPARE ENGINE –
This is a repaired and assembled, complete and correct (except as noted) genuine type 911/74 (high butterfly) or 911/75 (slide valve) RSR engine.
The engine was repaired, but not fully rebuilt (see below) and as a spare, does not include the oil filter plate or engine oil cooler; an ignition system or a fuel delivery system. It does contain all the ‘trick’ true RSR parts including: an unnumbered spares aluminum case with 83mm stud spacing; fiberglass jacketed head studs; twin (10mm) plug heads with original 43mm ports and Ate valves, in real RSR valve guides, Porsche springs, 906 non-adjustable rockers on moly coated shafts; Porsche RSR sprint profile center lube cams running in 4 (small) journal cam housings (83mm); light weight cam chain running gear and RSR intermediate shaft. It also includes the correct small fan and fan housing, with alternator and wiring, pulley, and rough light weight fiberglass ‘sheet metal’; a correct RSR Sachs ‘sporting’ clutch disc, correct RSR Sachs sport pressure plate with integrated release bearing and starter ring and the lightly damaged (flattened) exhaust headers that it rests upon. It includes a used set of Bosch spark plugs but not a set of injectors.
Parts that are different from, but may actually improve upon, genuine 3.0 RSR are:
1.) 98mm Mahle #504 1900 pistons / cylinders (Max Moritz type); 2.) a standard / standard (non-radiused) Porsche 6 bolt 70.4mm crank machined for ‘wedge mating’ to 3.) a Tilton 6 bolt ‘wedge mated’ solid aluminum flywheel and 4.) Hoeptner semi-mechanical chain tensioners.
Years ago this engine dropped the #3 intake valve due to a suspected cracked valve spring retainer (Porsche steel) that damaged the valve, spring, rocker, piston, head and cam. The valve, retainer, spring, piston, and rocker were replaced, while the head and cam were expertly welded and repaired.
The engine was reassembled to assure that it was complete in all respects with all its genuine RSR parts. This could be a perfect collection of spares but should not be run in anger until at least all the valve spring retainers have been confirmed good or replaced.
I can assure you that it is complete, genuine and correct… a can not assure you that it is fresh and ready to install and race. Please call 817 540-4939 CDT with any questions or PM for more pictures. $35,000 OBO
