mr_K Posted March 21, 2015 Author Posted March 21, 2015 After something like cruise or a brand.Will these 4age need some type of machining to fit?Im going to be using stock cams just a ported head and it will need valve clearance as it used to make sound.
Phil Posted March 21, 2015 Posted March 21, 2015 These are genuine Toyota so massive qualityThe should be fine without machine work on stock cams but your engineer would need to check for coil bind as bring stiffer and thicker they will bind sooner than stock.But that is no different than the difference between 4efe and 4efte (thicker and bind sooner)Only reAson I'm not running them is I'm running speedvision billets, and I don't fancy putting any extra pressure on them!Phil
mr_K Posted March 21, 2015 Author Posted March 21, 2015 So how do you think they will cope with stock cams?
Phil Posted March 21, 2015 Posted March 21, 2015 (edited) And seriously for anyone doing head upgrades on a 4e don't go hunting out Hrf cruise solid liftersThey are identical to oem Toyota parts from the yaris The ''zisco' valve stems oil seals? Are Supertech 4age seals less than half the price.I'd be surprised if the cruise valve spring aren't from a polo or 4age corrolla hence the specs not bring released.Phil Edited March 21, 2015 by Phil
mr_K Posted March 21, 2015 Author Posted March 21, 2015 True nobody will know.These days to make money people will do alot.Are the solid lifters off the 1nz-fe yaris 1.0litre?
