Walbro fuel pump enough?

[MidnightGTR]

Currently im running 2540's with exhaust and pfc, its making peak 351rwhp@14psi with the standard injectors and fuel pump.

Next stage is 700cc injectors, a intake fuel pump and a boost controller to run around 18psi or so, maybe 20psi max with a higher octane fuel

My question is will a walbro 255l/hour pump be enough to support the more boost and power? at a guess im assuming it will probably make a little under 450rwhp so will this pump do or will I be better off just going for a 044? I dont really like the idea of spending $500 on a nismo pump if a $200 walbro will be sufficient.

forgot to add im getting 80mm afm's too of course..

I have been told by a few good sources that those walbro pumps are pretty dodgy.

The are really only rated at 400hp at the engine. Don't skimp on fuel delivery, it's not worth running lean and detonating.

Go the 044 Cheap insurance if you ask me.

The walbro isn't a bad pump but about 250kw atw is as far as you'd want to use one, then upgrade to one of the larger external type pumps.

The good thing about them is they will drop straight into a gtst or silvia. The gtr uses a different mount.
