VR4 stock fuel pump.

Not sure if this has been asked guys, so point me to an existing thread if need be.

Basically just wondering what the stock fuel pumps are good for, power wise? Is it advisable to upgrade it? Thanks in advance.

I think its worth upgrading your fuel system as soon as you go bigger turbo or even upping the boost a bit say to 16psi.
The last thing you want to do is lean out and do some serious damage due to a 18 year old pump.

Thanks a lot for your input guys, it's much appreciated. I've been offered a brand new Bosch internal fuel pump for a decent price [$120] and I'm contemplating whether to upgrade or not...
