Larger Injectors On An R34 Gtt

[BeAgLe]

Hey all,

Just wondering if replacing the stock 330CC injectors with some larger 550CC on an R34 GTT will work without hassles or will i have problems???

I still have a stock ECU and wasnt sure if doing this will screw it up?

I want to run 12psi safely and was thinking of upgrading the injectors and fuel pump, but didnt want to if i'll need an aftermarket computer aswell as the cost is getting too high then...

Any comments are appreciated!

Thanks.

i run 12psi allday every day with no problems.

are you looking for more power??

You'll need a new ECU with bigger injectors... sorry bud! That was one of my main obstacles as well~

They're 380cc injectors....12psi is as safe as houses, you'd bennefit more from an ECU and tune.

but is the turbo happy at 12psi?

Hey All,

Thanks for the replies...

I wanted to avoid putting in a computer if i could because of the cost...

Does anyone know where i can get a Power FC and controller at a decent price, i can only find them at modyourcar.com.au for like $1300 or so.

I want to run 12psi safely and even up to 14psi if needed, and i plan to get the larger injectors and fuel pump, and i heard that a Z32 AFM from a 300ZX or something is required for a bit more power also?

Thanks.

Look on the forums; I think the going rate for PFCs with hand controllers float between $950 and $1000 delivered. There's a saving of $300 which can be put towards a tune.

Larger injectors, won't be necessary until you reach around 240rwkw which won't be with the standard turbo... a bigger fuel pump will benefit you more if anything.

The Z32 AFM offers more resolution over the standard one; these are around $300 new.

Thanks
