I have a 170ps stock jdm B16A lying around unused for 4 years and a used jdm ITR manifold and header. I am looking to upgrade the camshaft, valvetrain internals. After looking through the list of parts. I am looking to get the CTR intake and ITR exhaust camshafts along with other valvetrain upgrades together with my motor swap.
(1) Are the Type R lost motion assemblies really necessary with the camshafts upgrade?
(2) Can I move my B16A intake dual valve springs towards the exhaust side, just get the Type R intake valve springs and re-use all the spring retainers & seats? I think this can be done with the B18C, not too sure for the B16A.
(3) Can I just replace 8 intake valves to Type R ones and leave the 8 exhaust valves alone. Save $ and time from re-seating the valves.
Thanks.
