is the ITR valvetrain worth putting into a gsr head? i want to save some money and have reliable HP. give me some feed back who ever has it in their motors. thanks
Yeah is worth it, valves are lighter, intake cam springs are stiffer and retainers are lighter= reduced inertia, good for 8500 rpm
i have Jun springs, jun valve locks and itr retainers for sale if youd like. i have the spring test numbers too proving they are what i claim. $350 takes it all. then you just need a cam
from some research, i read i just need the ITR outter valve springs, is that true? if so, what inner valvesprings should i use? and for cams, i plan to use an ITR intake cam. thanks for all the feed back keep them coming.
sorry to bring this thread back.. got another question, whats the biggest camshafts the ITR outer w/ portflow inner combo take? i was thinking of starting with CTR camshafts then later go with spoon or even something beefier. TIA
