Solid lifters
 

Hi all! Hopefully I'm in the right place. I'm in search of solid lifters. Was searching in google for lifters and found that Miata uses them. They also looked like they would fit. Has anyone the diameter of the lifter and other measurements. I found the info here: Miata Engine History and Interchangability Guide

Thank You:)

um M2cupcar has your measurements. As for wich miatas use them i believe u will find the NB 1.6 liters 1999-2005 and the 1999 1.8's toda also makes a conversion kit for us earlier motors they might have specs u can use as well :D

All lifers from any NA or NB motor are interchangeable. Clearances using shim under on a 1.6 is a little more tricky because the mms shims are too thin. Reason being the 1.6 valve is shorter than the 1.8 by like a mm.

Thanks:). Was looking at M2cupcar posts and found that OE lifters are "shim on bucket". Thats not going to help me either then. Seems like no car has one piece solid lifters. The aftermarket ones are a bit expensive.

The aftermarket ones are made by Mazda, so they are essentially OEM. A set of 16 is $200, or $12.50 each. Please tell me where in the world that is expensive....

I'll tell you. When you have'nt got a job for a year and having a nice bank loan to pay, then everything is expensive ;)

And I did'nt know the Mazda lifters price. Others I have seen are more expensive.

Where can you buy this set? And where to get shims?

Thinking to get Intergal Stage 2 cam for my 1.6 NA

you should look into the mazda motorsport ones that bill at miataroadster.com sells. that is what im running in my car with supertech lash caps under them(shim under bucket) the lash is tricky to setup, you will prob have to have a machine shop do it.

why do you want solid lifters? I wish mine were hydraulic so I didn't have to jack with them again this weekend.

I wouldn't bother with solid lifters in a boosted car with stock revs if there's other places to improve. You'll get a better return on your dough invested elsewhere. It's different when you're bound to a set of rules, but like hustler points out HLAs are just easy. And if you do go solid, definitely go shim-under-bucket to get the max. benefit.1

The first time you get HLA noise, you will want solid.

And shims... wherever you can find them cheap. measure the valve stem and go hunting.

Ok, if you have to mess with solid lifters, why then is it that people want to swap the 99 1.8 head onto an older, lets say, 96 1.8 head? Doesn't the 99 have solid lifters?

The 99 head flows much better, that is the #1 reason. Makes more power.

Didnt Keith Tanner run a 99 head with HLAs in his targa miata?

MiataRoadster...STAY TUNED

he sells the lifter

i used supertech lash caps, i belive we have 6mm stems

you should not have to mess with your valve lash on a solid lifter head, they are non ajustable, once its set it shouldnt change unless something is wearing.

as far as the benifits

youll be able to run more aggressive cams, with steeper ramp rates
and the shim under bucket will let you run higher lift.

increased rpm potential. not only because of the direct contact, but because of the amount of weight reduction over a hydro lifter.

bigger cams and more rpm = more VE = more power

if your looking for stock 99-00 solid lifters i have a set from my head.

i had to convert due to me running integral R3 intake and R1 exhaust, up to 9000rpm

Attachment 201046

look at the difference in base circle diameter on my integrals vs the stock 99 cams
imagine how much faster that opens the valve, the ramps are very very steep, and the peaks are more flat for the extended duration. you can kinda get an idea of why solid lifter,shim under bucket is needed. honestly i would convert on any engine running a set of aftermarket cams, shaving weight off the valve train is worth alot, it left you run lighter spring pressures before valve float, and helps with high rpm,

i swear if i start my own company my slogan is gonna be

"shooting down flyin miata's since 20**"

How to fix lifter noise with HLA:
Change oil type

How to fix lifter noise with solid lifters:
remove valve cover
pull cam gears
check cam cap torque
measure and record lash on all 16-valves
remove cas and cams
pull lifters and inventory sizes
find a GF with an MS in mathematics to rearrange shims for you
order expensive shims on interwebz
wait 1-week
install shims and lifters
install cams
install cam gears
install CAS
set mechanical timing
bolt valve cover
start the car and pray to Satan that you did it right


Yeah, solid lifters are so much easier when they make noise. :hustler:

I cry for you when I lay down for bed every night.

I tried like 6X different blends in her n/a, yet every fucking time I pull into paddock with that car everyone looks to see who the douche is with rod knock. It is fine at street loads/temps. HLAs don't belong in men's track cars, period.

One of my underpaid minions will perform the needed steps to adjust lash on my solids, and I will be deified by those who I choose to subjugate in competition.

I talked to Integral about the same thing. I was curious about the lifters and going with better cams and such. He said Miata HLAs are good to like 8-9000rpm with stiffer springs and the solid don't yield any better results with the same cams. Unless you're going all out race with really high revs, you probably just need new HLAs. If you're getting new cams, then solid may also be useful if you match them correctly. Solid just isn't worth the hassle for most people (like me). I plan on sticking with my HLAs and upgrading to stage 2 intake and stage 1 exhaust cams from Integral.

With the 1.6 I built that is in BRGRacer's car I installed MMS shim under bucket lifters, and the full supertech valvetrain (valves, springs, retainers). I weighed all the stock pieces and then all the replaced pieces. It dropped an entire pound off the valvetrain. Doesn't sound like a lot but ask anyone who has driven that car how much it loves to rev and how fast it will. At 8krpm is absolutely sings. I'd love it if integral would go even further and make hollow cams for the miata. That could easily drop another 2+ pounds and free up a ton of wasted power.

And the reduced valvetrain mass requires less spring rate, which means less lobe resistance, and so on. Did you get the specs on the springs? We used the 1.6 EProduction valve train in the Motorola cup, just made some caps to sit on the valve stem tops and then set lash as usual shims under the bucket. Our spring rate was about ~15% less than stock.

We checked and reset lash after every race. That was usually a four hour endurance race plus another 2 hours of track and maybe more if we did any testing.

But for most boosted cars there's better places to spend the dough if you've already got HLAs.

Kind of OT, but should valve keepers/locks be replaced on a rebuild? Do they normally wear?

They should not wear at all. If they do you will find a dropped valve in your motor.

If the oil changes and flushed still dont make your HLA noise go away, you go out and buy new ones. Take the cams off, plop them in, and put everything back together. Still much easier than shims.

People don't put in SUB lifters because the maintenance is easier.... This thread is full of noob fail.

the integral stage 2/1 cams are baby cams so i would assume your fine. as for 8-9k with hla's, i dont know about all that

Yeah, I'm looking to keep my car comfortable driving on the street. I probably don't need anything over 7500rpm since my Greddy will probably crap out around there at 15psi, if not sooner. With proper cooling and all new HLAs, I'm sure they'll hold up fine for my purposes. If not, I can always install solid later and hate myself anytime they start to tick.

I do not know how many people have the shim unders here, but it was a very good modification for me. I never have to mess with it, and it made a considerable amount of power on my normally aspirated motor. I would definitely recommend it to any one who is doing any kind of top end work.

For all those concerned about lifter noise, I never had that knocking noise from my shim unders compared to what HLAs gave me.
