Popular Post mike_sekinger Posted November 21, 2021 Author Popular Post Report Share Posted November 21, 2021 More preparation today - light polish on the crankshaft journals and camshaft bearings. Dry fit of the marginally taller ductile iron liners, as this engine will be running higher boost (removing liner stand-in). Installation of oil pump, PRV and fresh front IMS roller bearing. Need to weight rods and pistons etc. These Saenz special rods are really sometthing. 3 4 Quote 1996 Esprit V8, 1998 Esprit V8 GT, 1999 Esprit S350 #002 (Esprit GT1 replica project), 1996 Esprit V8 GT1 (chassis 114-001), 1992 Lotus Omega (927E), 1999 Esprit V8SE, 1999 Esprit S350 #032, 1995 Esprit S4s, 1999 Esprit V8 GT (ex-5th Gear project), 1999 Esprit V8SE ('02 rear) 1999 S350 #002 Esprit GT1 replica Link to comment Share on other sites More sharing options...

cweeden Posted November 22, 2021 Report Share Posted November 22, 2021 What's the measuring device in the small aluminium cradle for? I am wishing I'd replaced my rods too after replacing just the conrod bolts with originals from Lotus, I suspect the new rods and ARP bolts might have almost been cheaper! 😖 Quote Link to comment Share on other sites More sharing options...

Pin guage for confirming liner nip. This version of the 918 Saenz rod were developed with Greg Dollimore for his high power engine. They are designed to cope with very high engine load.

alanlambert Posted November 23, 2021 Report Share Posted November 23, 2021 Lovely clinical work Mike. Could i ask as i am bolting mine together at the moment. i have found that i can rotate the crank about 2 degrees when the idler shaft is locked ( by the cam belts), Chain and gears are new and tensioners are adjusted. Movement appears to be the Morse chain on the crank gear. Does yours do this ? Ta. Alan Quote Link to comment Share on other sites More sharing options...
mike_sekinger Posted November 23, 2021 Author Report Share Posted November 23, 2021 Hi Alan, I remember that we had an exchange about that a while ago. I do not have anything like that level of movement on the crank, when the half-speed idler is locked. If your chain is new, then the only thing I can think is very heavy wear on the crankshaft sprocket - but I would not expect anything like 2 deg.

Popular Post mike_sekinger Posted November 24, 2021 Author Popular Post Report Share Posted November 24, 2021 After progressive material removal and re-measuring inside in the warm. Good result - max. variation afterward 0.05g. Interesting comparison to Stock - the CP forged pistons are less than 1g heavier than the stock, but their gudgeon pins are 5g heavier. Still very close to OEM weight for a superior piston. 6 Quote 1996 Esprit V8, 1998 Esprit V8 GT, 1999 Esprit S350 #002 (Esprit GT1 replica project), 1996 Esprit V8 GT1 (chassis 114-001), 1992 Lotus Omega (927E), 1999 Esprit V8SE, 1999 Esprit S350 #032, 1995 Esprit S4s, 1999 Esprit V8 GT (ex-5th Gear project), 1999 Esprit V8SE ('02 rear) 1999 S350 #002 Esprit GT1 replica Link to comment Share on other sites More sharing options...

Popular Post mike_sekinger Posted November 26, 2021 Author Popular Post Report Share Posted November 26, 2021 Christmas came early. I had a extremely welcome visit from Andrä to deliver the finished set of final carbon arches for the project. These are wonderfully crafted and I`m thrilled to be in the position to start with fitting those to the body in the coming days. Whilst Andrä was here, we had the delivery of the gearbox from X-Shift. Really looking forward to tackling the challenges of fitting this and the carbon clutch pack. 3 5 Quote 1996 Esprit V8, 1998 Esprit V8 GT, 1999 Esprit S350 #002 (Esprit GT1 replica project), 1996 Esprit V8 GT1 (chassis 114-001), 1992 Lotus Omega (927E), 1999 Esprit V8SE, 1999 Esprit S350 #032, 1995 Esprit S4s, 1999 Esprit V8 GT (ex-5th Gear project), 1999 Esprit V8SE ('02 rear) 1999 S350 #002 Esprit GT1 replica Link to comment Share on other sites More sharing options...
