Injectors And Fuel Pump Options

[crofte]

What would be a good injector fuel pump setup for this mild turbo on a RB25? Wanting to run around 1 bar boost with remaped factory ecu eventually. Currently i have the factory ecu.

Car is auto and i only want around 220 rwkw for a street car.

I have installed a FMIC, 3" PE2 exhaust and split dump, high flow cat. Splitfire coils. Gt2530 turbo.

Would 550cc injectors be ok for this turbo?

What fuel pump?

Please help me out.

550s would be more than enough...even 480cc s15 ones are more than sufficient...in fact...if the rb25 injectors are 370ccs thats enough too...

anyone?

I have a set of 555cc Nismo injectors if you want them.Direct drop in.They have been used for about 7000k and are in perfect condition.

Looking for $550 delivered.

I have a Nismo fuel pump in my car.Cant got wrong with those items.

anyone?

Didn't someone already reply?

As he said, 555 would easily do the job.

I have the s15's too running a hks 2535 on RB25. no probs.

(although for $550? go for that!)

Fuel pump? There's heaps of options, just do a search on the many Bosche/nismo/tomei options

Nismo and Tomei cost a little more but so much less muckin around.

[NYTSKY]

Yes go for my injectors

stardard injectors do 1 bar through the 2530, a $160 intake (600hp) walbro fuel pump will get more then enough fuel to the injectors...

talk to ur workshop....

s15 480cc will do the job and cheaper than NISMO 550cc

If you want to spend the cash then get the NISMO 550cc

^ both will be sufficient

If you want to spend the cash then a NISMO or TOMEI replacement fuel pump will drop straight in

If your happy to go with a cheaper pump then a WALBRO will also drop straight in

or a BOSCH 040 if you don't mind cutting the fuel pump cradle

Second the S15 option. Heaps of flow for the application.

Stock injectors should handle that much power with the factory regulator, if not get a hold of an aftermarket fuel pressure regulator and make sure you've got a pump that'll flow enough. They shouldn't need much more pressure at 1 bar. A lot cheaper than new injectors (unless you can find s15 injectors cheaply).

A walbro will be fine, just make sure you get the 'high pressure' version.
