Got an Ls-Vtec set-up in my 1991Crx. Everytime I go on the race track, the rad fluid overflows the container causing the car to wipe-up! I just changed the head gasket and other parts to fix my overheating problem. Note that this overflowing problem started since day one. Still using my stock rad.

Is it a radiator problem? Need a bigger one?

 

Try replacing the radiator cap.

Its the radiator cap that controls when coolant is bled into the expansion tank.

 

Changed that. (OEM)
