Hi all. I purchased a Crower cam for my 3T/2T engine. In Crower catalogue they say to use TRD valve spring kit, but I have contacted TRD Japan and asked for kit or specs of inner spring since outer is standard 3TC item and been informed they don't have kit and no access to specs anymore. I have contacted Crower and informed them TRD parts not available and asked another option or specs required with no help. Anybody have specs of springs TRD part no. 90502-TE751. I know installed height of outer spring is 1.446 to 1.5 inches. I don't know installed pressure or height of inner spring.
Thanks early for any info.
