hey guys i was just wondering....
i have a stock 98 civic ex(d16y8) and a t25 turbo setup...
and i dont know if ima need a bigger fuel pump..
if u guys can help me ill really appreciated if u need more inf just let me know!!!
thanks!

 

It would be a good idea to get a walbro 255.

I'm sure you know you'll need bigger injectors and for tuning/altering fuel intake it would be a good idea to get a fuel pressure regulator.

 

yea i got the 450cc and fuel pressure regulator well actually i got everything just needed to know about the pump... a got one off a crx its a 250 i believe will that one fit???

 

you can but its not recommended, you want that fuel pump as reliable *** possible and you are WAY too high up on that duty cycle to be even at a very high psi or even a low one

i tuned one for someone but i didnt like the stock fuel system its fine he said he'll take the cost if it blows so i gave him a conservitive tune, i richened up his fuel maps to a ridiculous level and it just barely came out lean throughout the entire powerband

5psi on a t25

 

wat exactly do u mean WAY to high???

 

pretty much if not maxed out

 

A friend of mine had a tune running a 99% duty cycle on his DSM 450's ..... I don't know how they survived

 

so are u guys saying those injectors suck???

No, we're saying they're a lot of injectors for most low-boost / low-power applications. Some DSM 330s would be a better fit, and easier to tune.

 

yea but da thing is dat those are da only ones i got and its just for boosting a single cam while my all motor ls vtec is being built so its koo.... it aint bad running those injectors is it??

 

they are just saying that it is likely they will fail due to the stress they are put through. For low boost they flow too much.

 

your factory injectors will not handle much more horsepower due to the fact that youll be close to 96-99 percent of your duty cycle, i dont read what eran says

the dsm injectors will be fine as long as you run a resitor, dont bring the duty cycle to high, but truth of the matter is unless you are over 20 psi on a t25 os sim turbo you wont be too high out of range youll be in range becuase those injectors were made for the mitsubishi turbo on a 2.ol 7 bolt 4g63


so in short

dsm 450-550 = fine under 13 psi
stock=no good for any power adder

 

ok... i do have a resistor and im planing to go 7psi will that be good???

 

you can go up to 12 or 13 saflety with those injectors, a stock dsm boosted 12 psi on the stock injector just make sure they are in good working order

ive done countless cars with this its a nice cheap injector if you dont belive me hit up hmt they have countless setups on that site too ,


i said not to run the stock injectors while eran said not to run the dsm's so completley worng

my next project is getting the 410cc RDX injectors functioning with the e85 fuel im running wish me luck

koo!!!!

 

stock fuel pump will be fine. and stock 240cc injectors are good for 185whp wich is around what the t25 will be making

 

^^^ thanks
