supra vs walboro 255hp, fuel pump questions Options

[xian 1g]

I currently have a supra fuel pump. I am underneath the impression that the supra fuel pump actually out flows the walboro255hp, at lower psi settings, while somewhere around 30psi boost the walboro255hp starts to out flow the supra.

is this information correct?

also, would the supra be large enough to support a large turbo, such as the fp30's?

if not, what would be recommended?

thanks in advance.

The Supra pump tends to have less fuel pressure issues and doesn't outright requite an AFPR like the 255 does.

This is an untrue statement that really needs to die off. They both should really have an AFPR on a 1G.

Well, I'd like to hook up a gauge to test it out, but with the stock injectors, I haven't noticed any idle or ostensible rich fuel issues by just dropping in the Supra pump.

I'd like to verify it with a gauge and AFPR though before standing too firmly on that point though.

I look at it this way, they either both need one, or both don't. If anything the Supra pump would need it more than the Walbro, since the Supra pump flows more at lower pressures.
