In doing this with the CA I need all the details. Is it a drop in affair? Do you have to put in shims like on or underneath the retainers or under the solid lifters? I imagine there is no machining required? And of course Tomei solid cams.
I decided to keep my CA in my car rebuild the head throw the rebuilt one on, save my S15 motor for a straight up race S13 project I have in the works.... (Pending TMS lmao) PLease anyone who has ever done solid lifters on their CA let me know! :biggrin:

The tomei lifters have a stalk under the crown and a small cup-shaped shim goes on it to adjust lash and can use the CA retainer.

RB26 lifters have the shim nestled in the retainer so you need that too.

I put that stuff on order the other day, should get it next week. Making me order SR parts, I feel so dirty.

To answer the "drop in affair" question, the answer is "NO". The amount of work, mathematics and time required to make this happen is exponential. If you decide to take on this task, do realize it is a daunting, but not impossible task. You can probably visit JUN or Tomei websites to get an idea on where to start. This is something that has to be done one lifter at a time and has to be documented. Keeping in mind that each modified lifter, shim, valve, spring and lifter will be married to each other, no exceptions. If you really wanted a nice revving engine, just make sure all of your lifters are healthy, install a set of competent valve springs, get you nice set of mid grade cams and a competent engine management system that will allow you to rev the engine at the most efficient and beneficial revolutions. Trying to rev the CA18 like it's a Gixxer from 1000rpm to whatever is pointless and anyone dry revving one trying to reach 8500 to 9000rpm is clueless.

I had a guy attempt to install my solid lifters into a head he had ported for me and silly me at the time, thought he knew what he was doing and installed this head onto my block because I relied on his reputation and entrusted in his past efforts on other projects he had done; mainly american big blocks. Well, turned-out this fool didn't adjust any shim with no blueprinting which meant that I had valves stuck open and so for and so on. I had to do the work myself and one of our Aussie members pointed me in the direction I needed to go, but there was no write-up. So after attacking this for a couple of days, I got it done and am able to say that again, this is no cake walk.

TMS you rock thank you for the illustrative pics(lmao and for ordering those parts!)! So I guess I order some RB26 valve shims????
Dee when you install these do you remember the typical clearances between the lobes and lifters you had? I kinda figured it wouldn't be super easy. Lmao I doooo not want stuck valves either! It's kinda the same way with the SR too only the shims are a little different because of the rocker arms. And btw the only reason why I want to see how high a CA can rev is because MAzworks did the SRVET with a head with rockers though different because the actually are kinda build into the head got that sucker up to 13,000+ rpm noooo problem. So my thought was when you don't have to worry about rockers at all kinda makes you wonder how high it can go? (I know I know pending all the supporting mods) I'm serious if I could put an F1 V8 into a 240 and have it living around 15,000rpm all day every day I would just because it would frighten small children! I really don't care how difficult it is making sure all the clearances are in spec. What I do care about is collapsed lifters 21 year old lifters and the thought of never having to worry about any of that after a quality job? Priceless lmao :naughty: The both of you TMS and DEE I will be talking to the both of you about this further as I get closer to the build. I need the knowledge so I don't #$%@^$ things up lol!

Will do fo sho Dee I appreciate the help. I say when I have all the parts together and have the machine work done you and me really do a write up on this for any people in the future that may want to follow your footsteps lol and then sticky it. We really do need a comprehensive writeup on this with pics because as you said I know it AIN"T gonna be easy!!! :crazy:
