i want solid lifters. i dont want to spend $300+ for something i can have made for cheaper.
ca18et use adjustable lifters! they're $6 each. i have some spare ka rockers i might subject to testing. i need some input on this. does it seem plauseable? take the ka rockers to a machine shop, have them somehow fit them together? does anyone have a pic of ca lifters outside of the rockers?

whats not solid about them? I dont know much about the single cam but it looks like all is solid.

the sohc ka use non adjustable hydro lifters. which are suppose to bleed themselves to adjust themself. they maintain proper clearance at all times until they freeze up. must i say they freeze almost anytime you over rev it just a tad. im tired of fixing my seized lifters, i believe nissan made faulty lifters. theres a bb which acts as a one way valve in the lifter itself. it bleeds the air out continuosly but what happens is the housing for the bb gets mangled and the bb doesnt seal right anymore and allows air in both directions, when it should only let air out. i fixed a few of my lifters by replacing the bb with a bigger one and using a higher tension spring pushing harder to help seal it better. between the bb and the spring i use a tiny washer as a seat for the spring on the bb. the ones ive done this way are holding up fine. but i would like to go solid to have more reliability in the higher rpms, along with being able to run a more agressive cam. hope that makes sense, im a lil hungover....


heres a write up on how to bleed the lifters....they are a pain in the ass!

I see now. I guess oil comes up through the rocker arm and the hyd lifter is under. could you remove the ball and spring and use shim stock and just shim the valves to get them to the spec you want. it would be time consuming to cut a ton of spacers out of shim stock but it would be cheep.

i thought about that but adjusting them would be time consuming like you said. having an adjuster with a locking nut would be sweet, id have to machine down the rockers though. there is barely any clearance with the stockers under the valve cover. maybe bart can fondle something together and sell his own kit. i know the o&j's conversion uses some toyota lifters, im just not sure which ones. the ca's look close enough to make work.

heres a pic from sideways's thread, it his 18et head. see the adjusters evilbrows.gif

actually that's a ca20e head just so you know the earlier pic with the front facing manifold is the 18et head I'm sure there's no difference in the lifters tho...
