Lightweight beehive valve springs for your M113K Mercedes




Jegs: Behive + retainers (Ti) - but you can also get tool steel ones possibly.
The valve keepers he suggests are not cheap relatively and must be sourced from ferrea or a distro.








make sure the spring cups are opened a bit and are the shorter version unless you wish a higher closed (on the nose)
obviously valve seals.
But yes. Some pics on my thread. He did great spec’ing this.
Also waiting to hear back from Chris to find out what the rpm capability will be and will the "short block" take a lot more of an increase rpm wise and still make power on stock cams.
What is the limit for rpm?

Trying to find out if there are some nice used cams to measure. VRP has two different kinds. Not sure the money is worth it. Lumpy idle is fine but wish for some more lift and duration. Have to be careful as I skimmed block and heads a bit.

Ill be testing this theory in future. Let's see how standard heads and cams perform with the breathing sorted out.




have aders and a Massaged intake, and the sc is ported a bit.
It would make my life easier in the short term. I can alsways do big cams later when I find the PTV limit later.
I will go with the springs and retainers, spin it to 7,000 and hopefully pick up on the top end but I am going to need a steeper gear , maybe 3.06 or 3.23 instead of the 2.86 I have now to get me higher in the rpm range through the end....I only use 3rd and 4rth gear
Also Chris mentioned the use of different valve keepers "Nissan" at the start of this thread. What keepers did you use for yours ?

Found springs for $385.00 so got those ordered.
All that's left is to find what keepers will fit....Nissan 240 sx ??

Yes. He has the actually ferrea number in the earlier post. That are surprisingly not cheap.




Bee Hive set up needs a 50- 60 thou shim to reach 90lb's.
Does this sound right to you Brendon when you did yours ?
I really thought I would have more or equal pressure with the new springs but guess not.
What is our cam lift …..290-,300 ?? So bind is at 1.240-1.260

The spring height looks too much. I recall 1.47 or so. What is also why your closed pounds are too low. Let me double check.
