Less is more for me and despite the "you will want more later on" I know I would be happy with about 350whp, heck I'm happy now. I drive a manual 06 scion xb so that should explain some.
Water/meth I would like to avoid. Nothing wrong with it just that there is more to go wrong
In regards to fuel pump I can't stand the whine of the walbro. I know many say they don't have it but I have seen and heard others that do
Any fuel pumps other than walbro to suggest? also i think I would like to go with rc 1000 IF i have to go that route

-As mentioned, DW301 pump is even better than the walbro
-RC 1000 are good choice, easy to scale/calibrate
I KNOw 350 whp is the border for stock vs modified pump and injectors but i wanted to know which is first to modify.....
Pump is 160$ for the DW and 360$ for injectors plus having to get tuned.
..Big difference in price so i would like to avoid injectors or keep stock around 80% duty cycle

For what it's worth i make 333whp/303wtq (mods in sig) using 91oct on a dynojet.. This is at 94% idc. I plan on cranking the boost up also once I get an Omni 4 bar map sensor, for logging purposes.
---Keep in mind, if your using Evoscan for logging, it's been reported that ~125% idc is the true 100% margin for injectors.. I've seen, from credible members, safely using 110% idc for extended periods with no consequences. I plan on doing the same..

So you want 350whp and 80 % idc in EVOscan on the stock injectors? There's no way you'll be able to achieve that on stock injectors w/ any fuel pump, you'll need to upgrade the injectors.

^ thanks, but thats why I was saying it's ok and around what hp would I be seeing at 80 - 90 % IDC....I have now learned if i would like 350whp I need injectors
Thanks

Don't think you're going to get to 350 whp with bolt-ons and 91 octane, at least not with a safe tune. Suggest that you start with the pump, and if you run out of injector, then do the injectors.

Hello silverevo. You seem to have pretty conservative goals, and reliability is one of them I take it. I would get a Denso 'Supra' fuel pump. One can't beat OEM reliability. Though I doubt you'll get to 350whp more than once with the mods you listed 
Thanks RMD
I actually though about that but I believe it doesnt fit in the stock housing. I believe I will settle on the DW and see how far I go with that and stock injectors then save up and get the rc 1000... They seem to be easier to scale for tuners with all the info out on them
