I've got an 85 GTS with an AW11 4agze swap, the supercharger has been removed, and I'm working on a turbo setup.

My fuel pump recently went out and I've been considering upgrading to a Walbro 255lph from a 91 supra.

My questions are..

Would that be too much for the current state of the engine considering it's going to be some time before I turbocharge it?

And.. If I go with the Walbro, should I go with the basic or high pressure?

And.. If I shouldn't use the Walbro, what other fuel pumps should I consider for my current application and for what I want it to become with the turbo?

All of the guides I have are kinda vague when it comes to specific details so any suggestions would be much appreciated.
