a stock pump is very old, so old they are near failure and i wouldnt trust it with a performance application.

a stock pump could take bolt ons, like header, intake mani, mild cam, exhast, intake, etc... I wouldnt trust it past that or on a turbo app.

you can use a stock fuel pump with an fmu, but thats ghetto, unsafe and last time I checked, this wasn't HMT

p.s. thats in a perfect world with a perfect 100% v.e. motor.

325 is flywheel, which is about 250 wheel give or take... and thats the pump and its ver ragged limit... no overhead, which means you are pushing the pump as hard as you can which shortens its life.. it will fail then you'll be out a motor...

dont be a cheap ***, spend the 100 bucks...

read much?

If you plan on making 200whp boosted then by all means use the stock pump. But eventually youre going to need a new one either before or after your motor grenades from leaning out because you were too cheap to spend *< $100 dollars on a part thats probably one of the cheapest pieces in your turbo setup.

ive been running turbo on stok pump + fmu for about 1 year. i have a d15z1 which has low compression. economy vtec model with t25 turbo. and its only about 90 hp stock. FYI i already have the walbro 255 so i will use it but realistically im pretty sure the stock pump can handle 180-200ish np as i have been researching this a few days now. (any more then 200 hp imma bend my rods so yeah that part kinda sux)

does anybody know the flow rate of the stock pump by chance?

Roughly a stock Honda pump flows 100-110 lph with a maximum operation pressure of 50-55 psi. After that lph drop to below half rendering the pump useless. So at max pressure and flow volume on a good running low milage pump mathmatically speaking it should be good for 220 whp with a stock static base pressure and no more than 10 psi boost otherwise fuel flow will decrease from to much pressure that the pump can't keep up with demand and this is with no safety margin which should always be usd when doing forced induction but that's what the pump will do from a technical mechanical standpoint

get the 255 bro its been proven to work. u want to gamble and try out new ideas go ahead ur the only one taking the risk.

I ended up going with a TT rx7 pump that was in a del sol from my old town, car made 427whp @ 15psi so I know it'll be reliable. Also should be plug and play for my car. I'm only assuming though, I've never dropped the tank on a DA before.

AlexDphoto

wow, what did you pay for that?

is it really that much money to buy a new pump with the correct install kit for your car? You dont even have to drop the tank for a walbro dude.

x2 the walbro is a great product nice clean install

Mr. Chainsaw

one thing you never buy is used fuel pumps. thats just like buying used pistons or rods, just completely retarded

if your not gonna boost it right, dont boost it at all! going turbo takes time and patience. so save money and do it right! i did it the right way and im happy with my turbo build.
and a walboro is less then a hundred dollars!!!!!!!!!!

listen to what everybody says get the walboro and do it right.

Walbro is decently priced and a good insurance, like everyone else say why risk blowing up your turbo setup that you probably just spend a lot of money on? I personally run a Denso 280lph TT supra fuel pump because it flows more than the walbro and very quiet, it is pricey though. Go with the walbro 255HP and call it a day!

Coutts

Are you kidding me? What's bad about used pistons or rods? People do it all the time. Jesus ****ing christ there are so many stupid people on here. I am truly speechless.

AlexDphoto

dude youre the only stupid person here thinking about buying a fuel pump from an Rx7 and DSM. its 80 dollars. i hope this thread is a practical joke, i didnt think stupid people like this existed anymore.

kyden

in a DA you have to drop the tank, unless you want to cut a hole and make a cover for it.

AlexDphoto

damn thats a bummer. glad i dont have a da

i'm done wasting my time here.. clearly I know more than I thought I knew.

fv8s

rainman did it and he was a ratard

golf-mk3

Thats why they make inline fuel pumps

azandford

only a ratard would run a stock fuel pump on a Fi setup....

yes you can run an in line pump but you goin to have to disconnect the one in the tank

smoovy

I have a DA, and honestly, a Walbro in-tank isn't hard to install. matter fact I did this by myself and took about 45 mins.....

hondaEg_808

your doing everything wrong! your wasting everybody elses time trying to help you and doing it right but yet you choose an unefficient way. do a turbo build right and you wont hve any problems.

redflaredcrx90

if you knew as much as you thougth you did you wouldnt be posting on the site asking for help. im not sure why would you wann rely on an 18 yr old pump.the really sad part the walbro can be cheaper than a stock pump....
