Help with Camshaft Choice Hi Guys n Girls Ive got a new engine in the build, and my machine shop wants a set of camshafts so they can mock the engine together in the workshop to ensure all the clearances are correct before they hand it all back over. So the decision for a cam, spring, retainer package has become abit important. Anyway the setup is as follows, Spool 2.8 stoker, 86.5mm pistons factory comp 1mm oversized tomei Valves plan to run a EFR 9180 - 1,0 rear and all the other bits like ross trigger setup, 6boob twin scroll, twin 3inch exhaust, HKS 100 cooler, E85 blah blah blah. The main things are the items listed. As the car is a street car, and will be driven on the street, i dont really want 280-290 Dur cams with 12mm of lift that makes the car a complete pig, i understand the 9180 is not going to be a v8 when putting around town so we dont need to go there. Ive spoke to Camtech and Kelford and they both guide me down the mega cam path, i think to myself surely i can go somthing alil bit lighter on, specially with the 1 mm over sized valves. Ive looked into the JUN high lift low Dur cam packages, but dont want to use crappy jap springs.. 272 dur 11.35mm lift The JUN cams call for a 1.5mm offset retainer. And also have a 29mm base circle, which im guessing will call for thicker buckets as the factory base circle is 32mm. Anyway, im sure someone out there has gone though the same situation so id like to hear your thoughts and suggestions.
