Hey guys, i recently purchased Tomei valve springs for my RB25det series 2 engine. i have a few questions. Well i took the springs the springs to a machine shop and when the took a look at them the intake valve springs were shorter then the oem valve springs. is this normal? can anyone tell me the free lenght of the tomei springs? also when they pressure tested the tomei springs it was weaker then the oem ones. This is just the intake side. The exhaust is ok. can someone help please. thanks
