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.

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.

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.

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

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.

      Ha ha ha, that's fair mate! We have the crackhead dogs now. Mainly because the missus wants the crazy dogs while she still has the energy and capacity to be able to keep up with them! Ha ha our current two are both Working GSD, there brothers and sisters (from the same litters) are in Police, Corrective Services, and I believe one did end up in defence force too. They're wild and fun, yet right now, both curled up asleep on the lounge room floor while we watch some TV. Mal is very likely the next dog (unless I get my couch potato guardian dog 😛 )   What are your Kitties names? Are you planning some house work, like those high kitty shelves, built in scratching post, and some cat passages from one room to another room?

      Who has a Infiniti Q60, Q50 (V37)?

      Yep, it was only an option on the Q50 Hybrid.  Same in Japan as far as I know. And doesn't use a centre diff like the Suby's do, so not the same as the WRX.  But it also isn't a reactive AWD like other Nissan AWD vehicles are, eg. Murano/Xtrail/etc.

      You should have got a Maine Coone then. Only thing is they're big. But so cool, and just like a dog. Or, just get yourself a high performance dog. That'll teach you for wanting Parkour indoors 😛

      Are you thinking of Bens R32? I don't remember if his went through the bonnet itself, but it went through the chassis rail. Brad (RISKIN) bought it, and turned it into a track car. It's funny how anti people are of Jim Berry now. I remember when I pulled mine out (during an engine change) and inspected it and found it cracking badly. At that point in time so many people were even on SAU, were so pro Jim Berry, and that was after Bens GTR exploded his quite publically.
