ok, my project motor is almost underway. this is what i haved goin:

2.0 liter resleeved gsr block with weisco pistons/eagle rods
fully built B16 head( port and polished, Skunk2 stage 2 cams , valves,valvesprings, retainers)
skunk2 intake manifold
RC310 fuel injectors, AEM fuel rail and regulator

which fuel pump should i go with? would an ITR one be sufficient? TIA

 

i would think that walbro 255lph HP i have it and its great unless u need a bigger one but im not sure ask about the walbro

for the $$ go with the Walbro 255 or 255HP. flows plenty of fuel for an N/A setup and only costs $90-100 shippped to your door brand new. that's what i've been using for a year now and i like it, the 255HP pump.

 

Walbro 190lph, the 255 is over kill IMO and is way too loud!

 

255 is way overkill with the 310cc injectors. you don't really need either unless boosted or nitrous. you're gonna be too rich and slower.

so should i stay with the stock injectors? or at least go 270?

 

i'd keep the stock injectors and pump for now, get on a wideband o2 and if necessary get an fpr and tune with that.

 

I myself have had great luck with a walbro 255 pump and a aem regulator. With the FPR i can put the fuel pressure all the way down to 20 psi and as high as 60psi with that pump and i have no problems. Just kinda nice to know that youll always have plenty of fuel whenever you need it. Just get a nice FPR to go along with it so you can turn it down. The 255lph pump on a stock regulator puts out about 50 psi of pressure at idle.(which is way to much) so use the FPR to get it down from there.

 

i would go with the walbro and an adjustable fpr

 

 

yes the 190LPH pump would be fine for the N/A setup. also the 255 pump does run at about 50psi with the stock FPR, which is what i ran for awhile last year.
with a quality FPR you can adjust it up or down as needed or desired.

the noise thing doesn't bother me at all. i think i got used to it, along with all the other noises, so maybe that's why i no longer consider it as 'loud'. BTW i went with the 255 cause i ran a DP N2O system on top of my N/A setup. stock injectors and rail too. but i still like it even though i'm not using N2O anymore.
