Howdy,
I've tried searching various forums and google with no avail and was hoping some cluey people could enlighten me.
Following the template...
Car - AE86
motor / part in question - Silvertop 20v valve springs for stock cams
problem - I am in the middle of changing out worn valve stem seals and thought I would measure the springs. There are variations of a few mm's + from neighbouring springs so I thought while I am here it would be worth putting in fresh springs. I am struggling to find information on the spring specs and tolerences for running stock cams and was hoping that I could get some advice on what valve springs I should run with stock cams and if it is anything else that would be worth changing while I've got it apart. Any links would to either tech or products would be greatly appreciated.
personal situation (if applicable)- I was considering upgrading cams/cam gears as the engine that came with the car was rebuilt with some JE pistons and lightened/balanced crank but was a bit scared of the breaking in process. I would consider manning up if I could find a decent person/workshop around wollongong to break them in, ect.
Cheers all.
