B18C1 Timing Belt Tension Too Loose Cold, Too Tight Warm

[TegDC2332]

Adjusting timing belt on B18C1 and the timing belt tightens up way too much when the engine warms up yet is floppy and loose when cold. This make following the factory procedure for tensioning the belt impossible since loosening 1/2 turn then turning 3 cam teeth will be too tight once the engine warms up (sketching/whining occurs when warm).
It seems as if it needs to be set at the minimum tension cold so it will not be too tight when warming up. I have read some have simply set timing belt tension with the engine warm. It seems like if everything is working correctly you should not have to do this though.

My question is there a belt that aftermarket that can help this issue, a belt that stretches with the engine or an aftermarket tensioner that automatically keeps pressure on belt as it loosens or tightens? Seems like the belt needs to expand and heat at more same rate as the cam gears engine etc.
Have a Honda belt with 200K on this engine.
