With the time to order an engine right around the corner, I'm researching what options exist and are popular when building an engine. I'm speaking of the little things that can make a more efficient / dependable / powerful engine. I've tried looking through endless threads but can't get many details. It'd be nice to have a good list for the options that a E/AB builder can ask an engine shop to do along with setting expectations and wish lists to compare pricing.
Here are the examples I've come up with:
Crankshaft balancing
Crankshaft counterweight (depends on the prop you are running)
Case machining to accept O-ring (Ly Con only I believe)
Case machined to have O-rings around through bolts
Matched piston / rod assemblies (2 grams seems to be the standard)
Increased compression pistons
Coatings on pistons, valves, springs (special coating?)
Flow matched cylinders
Porting and polishing cylinders
Roller rocker arms (mixed opinions on this versus the flat tappet)
Cold air induction
Cyro treatment for cylinders and pistons (Ly-con option)
Performance camshaft profile
Custom paint (obviously not a performance booster, just a build option)
Dyno testing / break in
I don't mean to start debates on these, which is better and what not. This is just a list of options out there for those of us that may not know engines like the back of our hand! I'm purposely leaving off injection and ignition options, as those are discussed at length on this forum and are easily searched.
So what other tips, tricks, soup ups, hot rod, better to do now than later, etc. items can we add to the list?
Thanks!
