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 parts like the timing belt and water pump, it doesn't make any sense to use low quality or generic parts. The labor for these jobs outweighs the cost of the parts, plus if either one of those parts fails, you will be stuck, probably will have to pay for towing, and additional parts may become damaged. There is a lot in between 'generic' and genuine toyota parts though. For example, Bando belts are usually very good quality, and you can get them for a lot cheaper than at a Toyota dealership. I just would try to avoid looking for the cheapest possible no name parts.
