Okay this is mearly an idea and if your on a really super cheap and super ghetto budget. Alright, there's a local junkyard/scrap metal yard that people bring like steel, iron, AL, and etc... Anyways, they have a dumpster full of the Garrett IC's from semi's and I was thinking of getting since they only charge for the per lbs of AL on those. I was thinking of getting one and since there so big to cut them down to cores since I could get like 4-5 good size fmic(custom coach or johnny racecar FMIC size) and don't laugh since I don't have access to someone who can weld AL or wanna pay to have someone weld new endtanks on them. Get ready for this one... make endtanks from fiberglass! I'd lay a couple of layers down and make a mold of it and then just mold it right to the IC core or does JB weld stick to fiberglass? i told you it was pretty low budget! How many PSI do you think the fiberglass endtanks would hold being molded onto the cores?

 

Probably about none. The glass would heat up pretty quickly, and i think it would become pretty brittle after it went through a few heat cycles, and thats all if you could actually make it leak proof.

 

I guess I'll just have to find out. I've seen people fb the inlet/outlet pipes on IC's before. Can't tell yeah how long it last though. lol

 

i think not only the heat, but pressure would blow right through that. and itd would be more work than welding endtanks

 

so your idea is to do something like this?

Another idea is to just get two small intercoolers, like from an eclipse and weld them together.

 

a friend of mine had the same idea (to use truck intercoolers), so he bought one off ebay. he cut it up and all that krap, then brought it to us for welding. turns out the things were epoxied or something at the ends, so it just melted any epoxy when we started to weld on tanks.
