Ae86 fuel pump options
2 to 2.2 hp per liter of fuel.......


255lph = 500hp-550hp
160lph = 320hp-355hp
80lph = 160hp-175hp



I DO recommend calculating your fuel pump need on your chosen injector volume. Calculate your injectors total volume, add 20% for wear, and maintaining pressure and you have the volume of fuel you need.

I DON'T recommend buying a fuel pump because it is "cool", or a "racing pump", or because your buddy says you need to run it.

Don't be an idiot.... if you don't know... LEARN from a KNOWLEDGEABLE source!

What happens if you have more volume then you need??? *IF* the system is large enough(feed line, return line, FPR) - the excess fuel gets circulated, and circulated. This over circulation of the fuel causes the fuel temp to rise.

What happens if you don't have large enough fpr, and/or return lines... the pressure in the rail can't circulate fast enough, the pressure builds, idle and off idle there will likely be excess pressure causing miss-fueling, and poor operation.

I take everything you say to heart Dan.

However I still have the standard 4age fuel pump
then the 4agze got swapped in and now I am still going up with the horsepower... I will be trying to get more HP in the near future.
So this is not a overkill idea In my opinion.

160lph is more than enough for now and more importantly the future.

So thanks again for all your dedicated answers and math!
It has helped me alot!

sorry bass ackwards way of telling you I think the 160lph will be good until you REALLY tear into the engine with major mods. @ that point you can reconsider another upgrade if needed
