I was thinking a set of 310 CC injectors & a Walbro 190 LPH fuel pump (in-tank). This will be tuned on Hondata. Just trying to find the right combo so I dont dump to much fuel & loose out on my gas mileage. Will be on a daily. LMK.

DSM injectors for $50, done.

i would buy walbro255 and bigger injectors, atleast 440cc. you wont be dumping loose out on your gas mileage if its tuned correctly.

So 190 LPH or 255?

I just dont see what would be wrong with a 190.

if you're concerned about gas mileage....stop right now. Sell your turbo setup and get a dpfi 1.5L.
Definately get the 255 walbro and at least 440cc's.....310's will max out quick on even a small turbo. Depending on your setup you might wanna even go larger than 440's.
Gas mileage out of boost should be like normal, but in boost b/c of 12:1 air/fuel ratios its gunna drink gas.

Either fuel pump will suffice, hell the stock fuel pump should be fine for a stock motor, but the 310s are too small imo. Stock ones are 240. 2nd the motion for some used DSM 450s. I also would like to say forget about the drag kit and put together your own kit (used parts if possible) to get exactly what you want and save money, unless you are getting a good deal on the kit. You can save more money by going with an alternative ems (crome / pro, uberdata). The injector size doesn't dictate 'how much gas will be dumped,' your ECU does. Maybe with all this money you saved you can afford some gas to feed your ~100% more horsepower. good luck

get a 255 pump and at least 550cc injectors........ with a good tune.

You think thats really neccesary for 7 lbs of boost?...

i'm running a walbro 190lph with 550cc rc injectors and it runs great. i herd the walbro 255lph needs a fuel regulator and i didn't needed that because i wasn't aiming for any hp higher than 200whp. the 190lph with 550cc can handle up to 300whp on stock honda fuel lines.

Where'd you hear this?

dsm 450cc's, resistor box, and walbro 255 hp.

Sometimes with those b&m adjustable fuel regulators (uses your stock regulator) the pressure of the walbro will cause it to malfunction. I've come across 2 set-ups that encountered this problem but then again I've worked with a few stock FPR's that worked just fine with the walbro hp pump. So in my opinion... it can be a hit or miss thing. I'm not a fan of the b&m fpr addition anyways though.

feed your addiction now!!!!! you will want more than 7lbs down the road.

I'm running a walbro and a B&M. My fuel pressure when up to 56, and i can only turn it down to 48psi.
Modifying the regulator will knock the pressure back down further

get a walbro 255lph fuel pump and at least 550cc injectors or some 450 dsms if you dont have the money but if you get the dsms member to take the resistor box too . but I wouldnt settle for a 190lph fuel pump because you know and I know you are going to turn that boost up more , so just make sure your fuel system is up to par just in case you get bored of a 7psi with a whopping 200 hp car lolz!
