I've just gotten a HKS twin power dli2 installed to the sr20det (which is e-managed). And now it has some weird starting/cranking issues. When cranking, it won't start. But when cranking, and you let go of...
asking on behalf of my friend, he drives a B8 Ford. He has tried quite a number of oils, but he finds the engine to be rather "rough" at 4000km. Everytime he changes the oil, everything is smooth.
