    What Upgrades for a Spyder E99?

    I have a dead Stock Spyder E99. Are there upgrades (drop ins) that are worth it?

    If so - please let me know what to keep my eyes out for.

    Is the body blue or black? It makes no difference, but that blue was sharp.

    I assume you're set with tank and barrel.

    My #1 upgrade is the valve. I really like the Trinity/NDZ valve (same thing). It's an item you'll have to make a WTB request for as they haven't been produced in some time. They should come with a valve stem and valve spring. You'll need to back out the RVA quite a bit, maybe even swap to a softer main spring.

    My #2 upgrade is the bolt. I use a stock 3 ring bolt however a 2 ring bolt is not the end of the world. I would refrain from a ringless bolt as your efficiency will suffer. I also have filed a ramp in the bolt at the top at the front. You'll have little trouble chopping today's small paint with a bolt modified as such.

    My #3 upgrade would be the board and/or get new rechargeable 9.6v batteries. I like the Virtue board for its options and the fact that it will take a 9v battery.

    And get yourself a feedneck you like.

        You know, I happen to have an NDZ valve that I put in a Spyder build that originally came from ScottieB and I agree. Might need to open up the front block port a hair if you're running a reg. Millenium front blocks breathe really well.

        But... without a smaller bore barrel, you'll leave a lot of the gains in the table. I have seen 50fps jumps going from a stock barrel (695?) to a matched Freak (.675 more often than not) with some of my lower-pressure STBBs. And more reliable cycling.

        Harbor Freight has cost effective NiMH 9.6s.
