Hi,
thinking to change 440cc injector on my turboed engine, does the stock fuel feed sufficient for that? aim around 230hp or 180whp

pioneer stop posting all over for the same question and answers... our fuel rail and pump can handle well past 900cc injectors...


take my advice now as otehrs will start to repeat me in the morning..

1. get bigger injectors 550cc minimum becaus eim only on 6.25 psi and my 440 cc injectors are maxed out.

2. if you really want to use 440cc injectors then get a return fuel system because 440 will be maxed

3. just read number one over n over....then go get tuned

Thx for the reply,
sorry about posting everywhere..
will try 550cc injector or make return fuel system

cburglb34

sorry if i came off harsh....

but it would be cheaper to do 550cc injectors rather than a return fuel system

paul_dezod

Well if you are only shooting for that low of power. 550cc and a walbro pump will do the trick. We carry and sell a lot of both

cburglb34

what paul said but honestly you dont need the pump most people dont run pumps even when pushign 300 hp

cburglb34

and paul he has a rav 4 he might need the universal pump

wait what?

cburglb34

yes this kid boosted a rav 4

pioneer411

yeah, i thinking to find used 550cc from Mazda RX7 or from Toyota Caldina 5xxcc high impedance. not enough time to post RC from US because end of this month going to dyno. maybe change bigger turbocharger.

Hi Paul,
thank you for the suggestion ,
if put walbro pump, in the same time need to change fuel rail with return fuel line and fuel regulator rite?

pioneer411

yes, walbro 255 intank pump, return fuel line, fuel regulator, and custom made fuel rail.

pioneer411

ya, 3rd gen Rav4 same engine with scion tc, just set it with 7psi, thinking to up 9psi, upgrade the fuel system, and maybe change turbo.

paul_dezod

No need to switch out the stock regulator unless you want to do a return system and push 300-550whp

dude im not gonna lie thats kinda neat...definetly one of a kind...

pioneer411

thank you for the comment,
440cc with stock fuel pump sufficient? or i need bigger like 550cc?
what is the stock fuel pressure ,
Thanks

pioneer411

thx for the comment,

here more pics for ya all

cburglb34

i told you 440cc and stock pump will not be efficiant just go with 550cc injectors and stock pump you dont have to change anything...

the stock rail will handle it


the stock pump will handle it

the stock regulator will handle it


and our fuel pressure is a raising fuel pressure



wat ever u do dont settle for 440cc injectors u will be maxing them out and detonating around redline

paul_dezod

I'd recommend 550s over 440s on these cars anyday.

The stock fuel pressure is 42-47 PSI on the tCs.
