Has anyone either done this on their own or had this done by a shop? What did you go with, what did it cost and where did you have it done?

 

i would polish your plenum, as i think the paint would come off being so hot, but not 100% sure on that so dont qoute me

but i have def seen people polish them, it does take a bit to get polished but it can be done =0)

Here is a pic from the mt run in the spring of a 350z with a polished plenum

 

You can paint your plenum or polish it yourself. if you decide to paint the plenum you will want to sand the plenum with a few different grits of sandpaper then spray it with a coat of high heat primer and then use som high heat engine paint.
If you want to polish your plenum go to Home Depot and get a polishing dremel kit (70.00) and sand the plenum down and polish away. Polishing a plenum is a lot of work. I know Edwin over on My350z.com will do it to for a small fee.

 

don't paint the plenum IMO...get it powdercoated instead. You can polish it yourself, but it's a lot of work...5 hours minimum.

Here is mine powdercoated black:

 

+1 if your going non polished route, ive seen 617g's in person and it looks flawless

but if you do wanted it polished, dont let alittle hard work stop you

 

Not saying he shouldn't do it just that it takes a while, but it's def a DIY

 

is that yours looks sick love the timing cover. I am having mine done right now with the chrome smaller covers

 

powder coated mine... had in lightly polished to get the sand cast off first otherwise it leaves specs... I don’t remember how much it cost less than $100 if I remember correctly. If you live in So Cal, OC-LA area PM me I’ll give you the shops info….

 

I do custom polishing in Socal...several people have my work blingin' in thier bays. Pm me for details. This is my engine...

 

I've seen this ^^^ engine bay and it's the best looking polished upper plenum I've seen. Great work!
