NEW INFO*** HLA's

**bpt323** · 12-31-11, 1:45

Found an interesting piece of info regarding FE3 lifters.
It appears as if KIA variant center hla units are .8mm taller then true mazda pieces retrospectively
wanted to pick peoples brains & see what/how they might effect lift/if it would yeild the valves being partially open on no load(obviously we don't want that)

Do you mean the HLA/bucket itself is .8mm taller than the mazda unit, or are you refering to the cup/follower inside the HLA being .8mm taller?

Could be useful for folks running reground cams, as the factory mazda HLA doesn't support more than an additional 1mm of lift/grind off the base circle.

Mazda lifter buckets are taller then Kia varients & have a tapered oil induction into the bucket. ~2.5-3mm taller on the lower skirt

the center HLA is 3 pieces. the bottom portion which contacts the valve is another smaller bucket that gets filled with pressurized oil.
Kia's have an additional .7mm height difference in this piece alone. (same inside diameter & depth for oil capacity)

the piece which pressurizes the lower bucket has an additional oiling groove in the kia units. not entirely sure the purpose for this... perhaps additional lubrication to prevent sticking

You are correct on this info. The kias are not the same and wont work correctly in a genuine fe3 head.

**bpt323** · 11-10-12, 11:20

thats not true. they work identically. there is no change its HLA regardless. it adapts on its own

im actually running a hybrid system between genuine & kia variant bits

**d0zxmustang** · 11-10-12, 11:34

so wtf is the problem with the one i have? When installed it keeps the valve open. It wont compress any farther.

you use the oem kia variant? idk maybe mine was mis-packaged after all...

**bpt323** · 11-10-12, 11:39

might not be proper bits. idk.

**d0zxmustang** · 11-10-12, 11:43

was yours similar to this (kia on right)? I measured the similar difference as you did so idk...

**bpt323** · 11-10-12, 12:09

ah geez. its been too long i can't visually depict unless i had one in hand with a caliper.

**bpt323** · 11-10-12, 12:10

i have noticed that the guide placement is different on the FE3 heads in terms of machined depth. perhaps thats a combined issue your running into.

**d0zxmustang** · 11-10-12, 12:11

ah ok thanks anyway. Im going to the junkers tomorrow ill pull one out of a kia there.

Someone posted in my other thread about you stating a saturn one that was identical? i searched but couldnt find the info.

I have found a genuine mazda fe3 hla online, but it would be $75 after shipping for just one!

!!! insane

I reject this statement and replace it with one that has more merit.

I was quick to jump to this conclusion due to a mis-packaged HLA I received. As others know that have used them personally, the Kia units indeed work fine.

Carry on fellow fe3'ers....

glad you got it sorted. any idea what the mismatched HLA was from?

**d0zxmustang** · 11-16-12, 9:37

no idea honestly
