for those of you with aftermarket coolant overflow tanks...

just looking to see what some people are using. i was looking at the greddy expansion tank, but it seems, at least from my understanding, that you still need another tank for the fluid to flow to, as the expansion tank is pressurized. i've been trying to search and look through build threads, but it still eludes me. am i correct in my assumption? i've also looked at the universal overflow tanks from like weapon r and carbing, and they seem to have the same design, at least 3 ports on the tank. is there anything similar to factory design?

What's wrong with the factory one?

could possibly have a larger FMIC and has no where to put one, or could be looking for a nicer one is my guess Jeff. I too am pondering because with the addition of a larger FMIC I need to find a new coolant overflow someting a little slender.

btw the reason I need the samething is because I did not cut out the crash support at all. Kept everything the way its suppose to be.

^^ he's right, my intercooler wont allow me to keep the stock one

The ones with extra ports and rad caps are to extend the cooling capacity.
If you want a diff size bottle, go to the junk yard

Expantion tank systems do not normally have an overflow resivoir. The expansion tank itself is not filled fully, Basically has a large air pocket that allows for the expansion of the coolent without dumping it into another resivior.

I just took a look at the greddy unit, and its not exactly a good example of an expansion tank
