I am considering venting a real Mugen Valve cover, and repainting it from it's original color. I believe these are extremely rare, and don't want to ruin it's value. Any thoughts?

Below is a picture of my painted MR5s that came out pretty good, and the valve cover I picked up from Fake

 

if your keeping it forever do it, if you ever want to sell it keep it original.

 

Its yours, if it makes you incredibly satisfied.
Do it!

Like NotNew said, if you don't plan on keeping it forever, keep it original. Value lessens when it's modified. The more original it is, the more genuine value it has.

If you just want a Mugen VC with vents, do it with a replica.


How much do they go for now? $1000?

 

Over $1000

 

Go for it.

 

I heard these are magnesium? might complicate welding if it is..
