One thing after another.....cooling system help

[Slomaro Z28]

Ok here is the car and mods, don't think any of it will matter but.....

98 Civic
boosted b18b1
forged internals
t3/t4 turbo
660cc
255 lph
tuned on chrome @ 11psi

When I get on it, in higher RPM's under boost, my radiator hose starts to collapse and it forces coolant out from the rim of my radiator cap. My cap is brand new and is 16 lb cap. I was wondering if there was any way of fixing this, other than the metal hoses ($122 @ summit). If it matters it's a 1/2 sized radiator.

steel braided is the only thing I know of. might be cheaper to buy some hose, and then the fittings seperate and make your own, but I'm not sure. Also check samco (?) hoses. I think they are reinforced.

Guess I should mention the hoses are brand new also

Well I fixed the problem, with a new aftermarket aluminum radiator. Guess it's not a bad thing to have a whole new cooling system.

True. Less worrying about overheating. You should be good

Yeah,

16lb Cap= New

modify a hose from an old smallblock chevy. they were spring loaded. there may be others but thats all i have off the top of my head.

just read that you fixed the issue... the radiator causing it makes sense though.
