Custom AST
whats your goal? Its going to be hard to beat an off the shelf design if you are just trying to cut costs. Most of the custom jobs I have seen over the years at least started with a metal AST from a vendor.

Yeah i was looking into just getting the materials and that is going to be just about the cost of one. What have you guys heard about the megan racing can? I was going to get the pettit one but it is 157 bucks. I need something cheap and reliable for now. I have 2 months left to finish paying the car and i need one to be able to drive it.

Look on the 3rd gen For Sale section, i got a used custom made ast from someone going to ls1 for cheap, 50 bucks shipped, looks pretty good, altho it does have an extra nipple on it, lol.

Yeah i may do that, but I was going with the Megan Racing that pettit had because they will have it to me within a day since i live 4 hours from them.
Megan is not really a crappy brand. What do you mean they warp? Like the metal rim looses its shape and leaks?
Hades : Idk what you mean by "Defined was also looking at making some too..? "

Oh i understand now. LOL
That is crazy about the warping of the can.
What would be the neggative effect of going to discount auto and buying some hose block off caps and capping the 3 hoses that go into the factory can for about 2 weeks until i gather some cash to get the Pettit can?

The pettit unit isnt very sturdy. Mine warped. I replaced it with one from Tri Point Engineering. The Tri Point unit is made much better.

Don't do this, the coolant will not have anywhere to expand to once it makes it past your pressure cap. It will just pour out of the car instead of going to the coolant overflow tank like it should.
My AST blew with 38,000 miles on the original motor, so if yours is still working, I would suggest getting it replaced ASAP.
I went ahead and splurged(?) on the Knightsports AST from RHDJapan. It looks really nice and clean, especially compared to the ugly orange peel black ones that are available. It fits perfectly, looks nice, and reuses the stock AST cap.
Worth it IMO.
