hello hello. so i just swaped a k20a2 in my ep3 and have a greddy turbo kit... i know its not he best kit but im hearing of people puting down close to 300hp and thats more then enough for me.i was just wondering, what siz injectors should i run and if a fuel rail is needed. i have 440cc injuectors and my stock fuel pump. let me know if you have some good info

[mitchlikesbikes]

i know that you don't need a fuel rail until like at LEAST 350hp. up until that point it's just for the bling. not sure what size injectors you need though. someone will know..

My JRSC k24a2 made 263whp because my 440s were maxed. Went to 750 and was able to reach 293whp at 9psi.

Was your k24a2 stock internally

Sure was.

at least some 650s. its like the same price for any injectors, so just get 650's, 800's 1000's. dont need a rail imo until much later than 350, i don't imagine the volume being much different, plus you have the tiny lines choking it up from the gas tank anyways. if you need a rail to deliver fuel, you actually need a return style system to really take advantage of it. the fuel pump i read was good for 350. a walbro 255l is only like $90.

good luck.

thanks for all the replays. i ordered 650cc injector with the welbro 255l fuel pump

[AttarixEp]

Good choices.

[differentK]

the 650s should be good with the walbro. im using ID 725cc injectors with the deatchewerks 265lph fuel pump. my 04 k24a2 JRSC put down 294whp/ 229tq at 7psi dropping to 5psi with belt slip past 6k rpm

[AKEP]

you should be seeing more then that. unless you put the ep3 pully on...but you shouldn't be slipping at just 7psi. get some belt dressing. you may have a boost leak though.

Injector Dynamic 1000cc. gives room for grow.
