I have a chance to pick up some solid lifters for a cheap price... is there any advantage of them? my hla's are starting to tick so i was thinking of using these to replace mine... any advice would be good

the advantages are that they don't develope the tick over time...they also increase your redline to 7500-8000 RPM (at least on a BP they do). the 1.6L and 1.8L V6 are probably a little different. but since the powerband drops off before this point pretty much the only advantage is that they won't tick.

solid lifters provides much smoother revs, and will allow you to rev much higher. HLA's can cause valve float into the higher revs.

If you use solid lifters, it is reccomended to change to a solid lifter cam. (99 miata cams would be an ideal swap in this case)

Wouldn't the 99 Miata cams only swap to the earlier BP? Mazda78 has the shorter block B6?

They've got the cure if you've got the cash.


Solid tappet cams have a less aggressive ramps compared to the HLA tappet cams. If you used the stock HLA cams with a set of Solid shim under bucket tappets you should be fine. The main thing you have to watch is valve clearence between the valve's head and the piston at TDC.

Totally untrue, just keep on believin what tuner websites and import magazines post and all you gonna end up is with a slow expensive car.

I cannot translate everything, but you can pick up the numbers.

Mazda 323 with a BP05 block and Kia Sephia cylinder head. By the way is the same cylinder head as the GT, LX, only that flows a little better, but the HLA are the same. It has totally stock cylinder head with Ross pistons and Pauter rods. My point is; its totally BS and crap the infamous solid lifter swap.

This car is pumping 530 HP on stock hydraulic lifters.



By the way here is another car:

What's totally untrue?? What does a 530hp 323 have to do with this thread? I think your missing the point.

Mazda 78 has no intention of running high boost. He merely stated his lifters are probably on the virge of collapsing as they ocasionally will. If I were in his shoes and had the chance to pick some up cheaply, I would too.

Other users are bringing up the advantages of valve floating of high revving engines, ticking noise, bla bla bla...

What a 500 + HP car got to do with this thread is (now that you cant figure it out for yourself) is FOR HIGH REVVING NO VALVE FLOATING CYLINDER HEADS OF 500 PLUS HORSEPOWER YOU DONT NEED SOLID LIFTERS.

in MUCH SIMPLER WORDS, HLA WILL DO THE JOB.

Defiantly: solid lifters are a great thing, epically on a boosted motor. Several boosted Miatas have reported dyno gains of up to 50 WHP from just swapping over to solid lifters. the stock valve train is totally retainable and you don’t have to swap out for solid. Its just one of those little extras for the hard core enthusiasts.
