bigger injectors???

[anponee]

i was thinking of getting bigger injectors for my 5sfe but have no idea on it.

just want something to fit straight in and around 350cc???

thanks for all help in advance!!!

What exactly have you done to your engine to make you think that you are maxing out your current set?

[trentmeyer23]

Do you have an aftermarket ECU to control them? Otherwise they will be dumping tonnes of fuel in, which is not a good idea.

as said above, bigger injectors are completely pointless unless you have supporting modifications.

no mods fitted to it yet but i'm in the process of aquiring parts for a turbo mod....

well you can use any top feed, high impedence injectors. I personally used a set from a laser tx3 turbo for mine (360cc)

thanks mick!!!

You can also use the high impedence 7M-GE injectors however they are only 315cc.

I checked new injectors out and ended up phoning the states. There were some risky side effects at changing them and I was told my injectors were good up to 300hp

Well I can tell you the 5S ones aren't even good enough for 200whp if you are still running stock injectors.

? Mines an SS3 197 stock

Each standard 5S-FE injector is good for 42.6hp(at flywheel) at 100% duty cycle. You have a ST202 that runs a 3S-GE with VVT-i, am I correct? If so things are very much different.

Also your power figure is 197hp at the flywheel as well.

If you are going to turbo a N/A engine, no matter what it is, you ALWAYS need to upgrade the fuel system (pump, injectors, etc)...

if you want to do it properly that is...
