I know it has been discussed again but I would like to here the pros' opinion on this subject.In Europe many tuners use solid lifters on their 4G63s and they say they are working fine.But others (including Buschur and AMS) say that solid lifters simple don't work on our engines.
From my personal experience with the BLE solids one thing I can tell is that it is almost impossible to adjust them properly.What do you guys thing?
It would be very helpfull to have well none tuners like Buschur and AMS to explain us whats wrong with the solids and finally if they worth it or not.

I used the BLE solids on my motor for a few dyno pulls.
1) They are very hard to adjust once installed. to se the lash you have to pull the cams.
2) the tolerances where way off
3)I broke 2 Jam nuts off while trying to loosen then when first pulled them out of the package
4) they are noisy as hell, you think a lifter tapping is bad how about 16 of the clanking at idle
5) there is no use unless you are running a Piper Drag Cam with so much lift and such an aggressive lobe that it collapses lifters, but at the point the car isn't street driven and is probably inspected after each race weekend.

Agreed, there is no reason to use solid lifters for these engines unless it's a situation where they are absolutely necessary. They create far more problems than they solve, especially when there is no problem to solve in the first place.

Thanks for the interest guys.I hope more people join this thread with their opinions!

I've tested BLE and they really SUCK!

If you have to use solid lifters go with JUN, they are much easier to adjust. They use shims.
There is a Mitsubishi tool that can be used to compress the valve springs so you can adjust the lifters with out pulling the cams. It's very expensive and I don't know if there are any other tools for it out there?

Another option is what i will be running with my Piper cams....

A gutted stock lifter that is machined to fit a Ecotec solid lifter inside that is shimmed up to the proper lash.

The Ecoteck lifters have spun 10k rpm on the dyno no problew..... only PITA is making machining the shims.

Thats very interesting.Does the head of the GM solid lifter fits with our rocker arm?

Yes it does...... Once i get my car running i might go into production.

Any other thoughts on this subject guys?

just wait till the 4b11 hits, doing cams will become so much more work, tappets are no fun.

Only reason to run solid lifter if you run very high rpm and or a very nasty cam.

i was considering doing the solid lifters in my VIII but thanks for the posts, definitely made me re-think that choice.
