Tried posting in the tech section but i am not really getting any help.

I was wondering if a walbro 255lph intank fuel pump will be necessary or net me any gains in performance with my setup?
Here's my setup:
2nd gen b16a, ported and polished, 3 angle valve job, milled .030", crane stage 2 cams, crane dual valve springs and ti retainers, ferria keepers, SRI, bored 64mm throttle body, AEBS intake manifold, hondata heatsheild, 4-2-1 header w/2.5" collector, 2.5" high flow cat, 2.5" exhaust....tuned with adj cam gears/vafc2.
Can you think of anything else that would be benefical to my setup?

 

yes get it http://www.camp1320.com

 

anyone else?

 

190lph will work fine too. 255 i would use for a turbo vehicle

 

yeah hondata !!!! or crome or uberdate !! The fuel pump is good but teh fuel pump alone won't be enough. With hondata or crome you can see the duty cycle of your injectors. You haven't said anything about injectors so i assume you use stock injectores. I think you are way over 80 percent duty cycle so you need bigger ones !!!!

 

really? Ahhh crap....what would be more beneficial to my setup....like 310cc injectors?....or a 255lph pump. Because i got a 255lph pump for cheap but am debating selling it and grabbing some injectors.
Damn stupid car...and new injectors would mean more dyno time and tuning eh?
I have been planing on tuning with uberdata but i figured i would upgrade a little more before doing so.
Would 310cc's be enough or should i go bigger?....keep in mind that a b20vtec is in store down the road a little.

 

For the b20 you need 440 cc injectors. But you need both !! The fuel pump and the injectors.

 

hey i have a walbro fuel pump..is there anyway to tell specifically which one it is??

 

sure....check the part number stamped on the side...mine says GSS342....or something like that....then cross reference it with the part numbers on walbro's site.
So, keep the pump AND get some injectors...damn it never stops with this car....lol
thanks guys

WTF? there are cars on this site making 200+whp on stock 240's, where are you getting your info? LOL! there was recently an lsv on here that made 217whp on stock ls 240cc injectors. 255lph is overkill, i mean if FI cars make 400+whp on 255 pumps, then please explain to me why 190lph is not enough? i made 200whp on stock 240's and so have many others. and my pump is ONLY 165lph. i think that the reason some set ups need bigger injectors is due to there form of tuning. will the bigger pumps net you gains? no. not if its untuned, but even then, i can't see your numbers go up. lets keep it real guys, and save the shittalk. and, why are you referring to b20? he's running a b16.

What was your injector duty cycle?

That's why i am talking b20.

And that is part 2. 80% duty cycle is good, not 99 % so 310 cc is not enough if you go over 210 whp. 440 is good you don't have to worry about if you have 220 or 230 whp. Do it right the first time. And if you buy a walbro why would you buy a 190 lph if you can buy a 255 lph for almost the same price.

 

b16c1:
i did say that i was going to be running a b20 down the road....so i didn't want to have to buy injectors again....but yes, as you well now by now man, i am currently running a b16.
But yeah, i never thought that my stock injectors were an issue, but rev limiter seems to think otherwise....just trying to get some more feed back on this.

 

i have 440cc and a stock pump, my tuner and i both say i dont need a fuel pump

and im a gsr 2.0 high cr

440 is good, but, its still overkill. i'm pretty sure that Omniman made 220whp+ on 310's and a vafc. my duty cycle was in the very low 80 percentile. 82% max. there is one thing that has to be taken into consideration. there people that have done it, and, others that have opinions. i'm not doubting your experience, but every set up is different. i don't overrev my b20v (7500rpm), i don't have big cams (ITR's) i have relatively low compression (9.6/1) and have a non ITR im (?), and 60mm t/b and Hondata. i have a good set up and tune that doesn't demand mad fuel, that's all. and it runs safe. i don't disagree with any of your recommendations, its just that alot of people believe what they read, not what they have experience with. trust me, there are people that have made 200whp on 240's & OEM ITR pumps. its not really smart, but doable. i'm just stating that a 190lph pump and 310's are good enough with efficient tuning.

dont listen to this guy. 440 is over kill. 310 is overkill too. too much fuel is not good. 440 are usaully used on turbo cars.

If you put it like that i agree with you. I was thinking more like 2.0 gsr with high cr and crazy cams and stuff. A setup like for example jason bouchard. Than i wouldn't go with the 310 cc injectors.

That is just saying stuff without thinking about it. Most turbo cars i know are running way bigger than 440 cc. I know plenty all motor guys that are running 440 cc and i even know one that is running 550 cc.

 

Dont spend money unless you really need to or have extra to throw around. Keep your stock injectors. If you ever decide to go b20 just find a new head and keep your old setup as a spare. Your probally going to want to build ur b20 anyway. as for the 255 you already have it may as well keep it. if you want a sleeper just find a gsr or ls crank and rods and slap those in. You will make some good power.
