light weight lifters?

[hypedz34]

ok besides improved throttle response what else does the light weight lifters do for the lumina z34.mine is a 93.what other gains will i achieve?and do i have to do any other mods to get the full potential out of them?my z34 engine is stock except a cai.any help is greatly appreciated thanx

I would think higher revs would come into play as well... Less valve-train weight means everything can work quicker and prevent valve float at high RPM.

Make sure you have good oil flow. I know I can hear mine tick for 10 min when its cold. I am doing a dry sump soon so all of that should be gone.

so with higher rpm's would help bottom end tourqe right?

[d.o.h.c]

No, Higher end RPM means you can go higher RPM. The advantages of this are, if your a 5 speed you can go longer before you shift into the next gear, also bringing your next gear closer to the power band when racing.

If your an auto they just help with a tune.

In all honesty they dont do anything that I have noticed, but make noise. Infact they look like the same material so I am wondering what makes them lighter if at all.

Not worth the $400 IMO. Your better off building a dry sump to free up power and increase engine life, or put the $400 into piston/Rods.

If I did it again I would not spend the money on these at ALL.

[hypedz34]

yea i have an auto.well i guess i'll just put that money towards something else any ideas?

[d.o.h.c]

What are you looking for, motor or all around upgrades?

So you are saying they aren't really lighter than stock?

Not worth the $400 IMO.

They are $299.99. Have you priced stock replacement lifters? If you need lifters, then they are worth using. If you don't need lifters, then there is no reason to tear things apart to replace them.

I would start else where as well. like ben sen not worth the work unless you need them replaced for other reasons... Trans cooler if you don't have one would be my very 1st install.

I was incorrect, sorry $299, they use to be a bit higher though. Yes I have checked stock melling lifters and they runs around $220-250 for the set. Are yours worth the money, YES, would I swap them if I did it again, NO. I am not saying that they are bad, or that they are not truly lighter, I am just saying I personally dont like them. The noise they make on start up is not worth the higher RPM in the long run. Even with my oil pump champhered and bluw printed and the oil passages cleared of casting flash, I still think they need more oil up top.

Again, not saying dont buy them, I would just start else where first. Like shane said a tranny cooler if your auto does not have one or a oil cooler, intake, pulley, exhaust, etc.

ok exhaust wise how would i go about doing that because i know they do not make any headers for the z34.

[RedZMonte]

pick a set of mufflers, a resonator and have an exhaust shop build the piping. i wouldnt go any larger then 2.5". I would recommend a Magnaflow/Carsound high flow cat and relplacing your stock mufflers and resonator. how loud do you want to go?

I sell exhaust.

i purchased the lifters and yes they r slightly lighter i weighed them and compared them to my old stock ones. are they worth it? yes if you need to replace old ones for other reasons i had 3 sticking lifters that y i bought them. but if your got money and your engine is apart ide get them. i upgraded my lifters and springs and retainers when i did my engine rebuild. imo if it wears replace it with stock or if you can find it better than stock parts
