So my 1.8t B5 needs a fuel pump (fairly sure, but still need to confirm, but stuff I read point to that being the issue). The thing is after i get a fresh motor (with turbos) for my allroad I plan on building the motor I pull out of the allroad to a full stage 3 and swap it into the A4. I'd hate to buy a new fuel pump for the 1.8t and it not be enough for the stage 3 2.7t, but I suspect anything that will feed a stage 3 2.7t (turbos not yet set, but considering RS6 BW K24s or SRM Hybrids & aiming for 500whp ATM on 91 octane). So my next thought was is there a pump that would work in the 1.8t now that could be swapped into the allroad (with the shorter tank) and at least supply enough for a stage 1 (MTM 350 bhp chip) 2.7t? Or will it still be way too much pump for the 1.8t (stock 150 bhp)? I figured since this is crossing chassis/model lines this might be the best spot to ask. I've done some looking, but mostly it all deals with Stage 3 2.7t (B5 S4 & C5 Allroad, that's how I know the allroad tank is shorter).
[headbang]Edit: Apparently (from FB comments) I wasn't as clear as I first thought. My question it would seem should have been:
"How bad is it for the pump if I'm running a pump rated for either 300whp (to be moved to the allroad at a later date) or even one rated for 600whp in a car that is only developing about 110whp (at the moment, will hopefully have a motor that will put down 500whp eventually)?"
I haven't found anything online about over-sizing a pump (much less that significantly) and issues/drawbacks/concerns... And I'd hate to possibly ruin a pum[ just to find out. Hope that helps...
