Can any one see any issue with fitting a walbro 450, was for another project I was doing but think I'm going to break that an concentrate on the Impreza, I use to have a 255 but power aims mention I needed something bigger so exchanged it for a 450 😁

400's goes straight in and i can't imagine you'd need bigger than that.

 

If you do i would suggest swirl pot setup anyway

255 would be plenty then. I'm on a walbrough 400 and not even close to maxing it out

ah right, if you dont have any plans to go higher power later then just sell it on. If it aint broke, dont fix it ;)

Well that's the thing, not sure what I may do haha got a fmic, GT3582r, fpr, external wg, motec M4 pro, and some huge injectors just sat too lol so anything could happen

Gonna need a rebuild and alot of money spent for that so fuel pump will prob be the cheapest thing you;d have to buy. Also prob into swirl pot setup at that point anyway.

 

If your happy with what you have leave it be. Can always keep the pump as a spare, although i'd sell it and buy one later if i needed one

This is very true, was just reading somewhere that at a stage 2 map it's advisable to update the pump.

(God I hate asking loads of questions, you can tell me to bogg off if u get bored of them too haha)

dont worry about loads of questions - stage descriptions for tuning / modification can vary widely dependant on tuner / forum / model of car. If you change the flow into and out of your engine a remap will ensure the fuelling etc is tailored to the mods you have made
