OEM parts vs generic, is it that much better? Options

[Hanyo]

I'm about to change the timing belt, water pump, pully on the celica.

It has got me thinking, is it worth it to put genuine toyota parts in there?

I mean, how much longer is the old 7afe gonna last before the valve seals leak and i will be pulling off the head anyways. I've given up on modify the celica, and ditching plans to turbo the 7afe. So this engine will not be under the heat and stress modified engines face.

for a 7afe or a 5sfe, go cheapest brand you can find

for a 3sgte, use toyota (i use all oem on my car, even though im a firm believer that other brands will work, i just do it for ****s and giggles)
