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.

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.

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.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
