drowning in broken cars Posted October 9, 2014 Report Share Posted October 9, 2014 So Ive searched and searched and cant seem to find any info on it but can anyone verify that 280zx outer valvesprings fit a ka-e and are an upgrade? What about spring pressures, are they actually stiffer and by how much? just cant seem to find any useful info about ka valvespring upgrades Quote Link to comment
datzenmike Posted October 9, 2014 Report Share Posted October 9, 2014 The KA intakes are smaller springs. They might fit the exhaust. Quote Link to comment
