    FS: BP DOHC Solid Lifters, Rev higher! Gain lost powa!

    I have a set of sixteen (16) solid lifters from a 99 Miata. Includes the lifters & shims.

    The shims vary in size from 3.124mm to 3.204mm's. You may have to buy different sized ones to properly match to your camshaft lobe's wear.






    For those undereducated ppl...Solid lifters replace the HLA's that are famous for the obnoxious "ticking" sound you hear with Mazda valvetrains. Starting in 98' Mazda scrapped all HLA's in all of their engines and installed Solid Lifters in all of thier engines.

    The benefits of solid lifters include:

    (1) being able to rev higher without the risk of "valve float

    (2) getting rid of the ticking sound for LIFE, have a quiet valvetrain for a change!

    (3) gain lost power. If your valvetrain does tick...one or more of the HLA's isn't pumping up properly and isn't opening the valve fully. solid lifters consistently open the valves to proper spec, ensuring the proper amount of air is getting into the intake valves or out of the exhaust valves

        does 1 need to get new cams to use these or are the stock cams good?

          What happens when you send me PMs such as:
          -Sending me a stupid question (no common sense, no logic, impractical, etc)
          -Sending me a question that can be found searching or in the FAQ
          -Sending me an illegible question (ie: bad grammar)
          No you WON'T get flamed, you'll get ignored. The results will vary if you send flames/insults

                is there a way to determin if i need differnt shims or if thos are good?
                can some1 point me in the direction of where i can learn about cams? im such a noob...

                  heres a picture of a valve.... (this is the burnt valve from my Z5... but its jus for illustration purposes)

                  on top of the valve stem sits the valve spring, and on top of that the retainer (which is like a plate, to keep the spring from falling off) and ontop of the retainer there are keepers (little clips that hold the retainer on)

                  now on top of the retainer/keepers sits those buckets that harlem is selling
                  and ontop of the buckets those shims

                  the cam lobe comes in direct contact with those shims....

                  so when you're adjusting your valve lash, you stick a feeler gauge between the shim, and the cam lobe... if there is enough clearance (you'll get that info from a haynes manual or whatever) you're good

                  if theres too much clearance, you need a thicker shim
                  if theres too little, you need a thinner shim

                  over time the shims slowly wear and they create a gap, and that is the ticking noises you'll hear in solid lifter cars when they are out of adjustment (the valve lash needs to be checked every 100,000 kms)

                  it is actually ideal to keep the same shims that started off on that lobe (or get new ones)... because each lobe will wear each shim slightly differently, and moving them around could potentially lead to premature cam wear

                  now on my Z5, they have solid lifters... i dropped the box that was holding them because im way too cool...
                  and i mixed them all up
                  so i just measured each one and put them where the fit best

                  so i've moved around shims between lifters and so far havent had any problems related to that.... but its not "suggested" to do what i did

                  there is no way to find out whether or not you need different shims at this time, because you have to find cam's, then you gotta put in the cams/lifters/shims
                  THEN
                  measure everything
                  THEN you'll know if you need more

                    thanx for the 101 on valvetrain pigeon!

                    Gro about how much are you looking to get for them?

                      Nope.. You don't.

                      There is actually two cam measurements that are CRITICAL:
                      1) base circle distance
                      2) lobe-to-lobe deviation

                      Both of these are WELL WITHIN SPEC TO USE WITH SOLID LIFTERS.

                      Base circle distance was within lash spec, and lobe-to-lobe deviation was less than .002!!!!

                      The cams are not only the same part number, but the same grind from the ones I measured.

                      I Installed a set of solid lifters into my K8DE (just to get practice on measuring the valve lash w/my new tool). The valve lash was under .005 and iirc valve lash .010 or under is acceptable.

                      So, yes, your stock cams will work.

                      Now, if you run mike323 cams or any other regrind, you will need to redo the lash and there are shims out there that will work to take up the lash OR you can buy new lifter caps from Mazda to your spec measurement.

                      With solid lifters you will be getting FULL CAM LIFT to the valve rather than the HLA determined value.

                      Thats why the 626s typically put out about 3-5whp stock with the same mileage. Our HLAs can't hold pressure fully after about 20k miles or so. .01 inch doesn't see like much but when dealing with cams its a LOT so if your HLAs compress .1 inch at max lift at high rpms you have lost a third of your valve lift in the most critical time.

                      Now, as far as regrinds, you really should ask the regrinder to see if he can keep the proper lobe-to-lobe measurements. Some regrinders use some very aggressive ramps that also might put undue stresses on the valvetrain and so that would need to be worked out. Some capitalize on the fact that we are using HLA and use them as a sort of fluid damper and their grinds won't work with solid lifters unless you also run higher valve spring rates and stronger/lighter retainers.

                        you CAN'T use HLA cams on solid lifters because the ramp angles are ****ED... you get WEIRD drivability/performance issues and incorrect lift... not to mention weird lift issues inbetween full lift and opening/closing (ramp angles, duh)

                          why would so many probe guys be rocking solid lifters w/HLA cams and GAINING power and performance if this were true.

                          Doesn't make sense anyways. HLA's are just as flat as solid lifters. If the hla were working properly it might as well be solid, the cam lobe is still the same and gives it the same lift either way.

                            I wouldn't run a HLA cam with solid lifters... just asking for bad news.
