hey guys my car is pinging since im still running the non turbo fuel pump with a rb25det motor.

i have a bosch 040 fuel pump and a sard fpr and nismo injectors in my room.

im not going to get my car tuned anytime soon so what should i do?

i have a power fc and i goto "ect" and goto the bottom section and click yes, assumed it was factory reset but i let it idle for 30min as it said,

and it doesnt seem to change and the car was still idling rich so i just put the stock 1 back in.

so basically should i just add the 040 pump and do i have to add that fpr aswell?.. or i dont need to change anything else except the pump?

or should i add the nismo injectorss, fpr, 040, and try to reset the pfc and turn the injectors down?

i just want to know what i should do,

#1: 040 -

#2: 040 fpr -

#3: 040 fpr injectors pfc -

thanks

I would stop and have a good think about what you are doing instead of creating about 15 new topics when most of the answers have been asked and answered so many times before.

Changing the pump will make sure you have adequate fuel supply. There is no need to change the FPR or injectors.

Given your reluctance to tune your PFC I am not sure how you will ever sort out all these issues. Doing things half arsed seems to be part of your problem.

If it was my car I would've just bought a fuel pump and installed it. No need for FPR, injectors or PFC.

Regardless of anything, you should install the pump and upgrade your fuel pump wiring.

If the FPR has a gauge built in it will be a handy diagnosis tool, might aswell install it, search the forum for adjusting aftermarket FPR (set it to stock pressures).

If there is no gauge on it then there is no real point to installing it as the standard FPR is fine. Either keep it as a spare or sell it.

The larger injectors are not really needed unless you are going to get it tuned and plan to reach figures higher than the stock injectors will allow.

Again, same with the powerFC. Unless you have decent mods (or plan on them) it's not really needed.

If you really want to put them in the car, find out how to reset the powerFC to standard maps, install it and the injectors, adjust K factor to suit the size of the injectors.

So this is an N/A ehgine with a turbo put on it, are you still using the turbo or na injectors, if your using na then i would certainly upgrade to atleast turbo injectors, what ecu are you using na or turbo, either one will not run all that well as the engine is under a completely different set of circumstances that it was designed for, i would park the car untill you had money for a tune, use the bigger injectors, pfc and get a z32 as well, the fpr is an option but really an fpr is mainly used to get a little bit more flow from injectors when they start to run out of steam, this shouldnt happen if you have chosen the right size injectors.

Lol I know... 1st I had all my parts and I was told I need a fpr,

then I was told I reallyshould get injectors before my tune so i looked and found some sard injectors,

then everyone said I should get nismo so I saved for them,

them my highflow turbo seals went so now I still can't tune it :down: how annoying this all is...

So now I just want to add what I can and I need the pump 100% so I was asking how I should do it.

yes I've had many post's but I've also ran into alot of dead ends so Now I'm just doing this and saving/fixing everything lol!

Hope that made sense cause I'm on the iPhone typing quickly,

It's a fully converted n/a to turbo... Engine, loom, ecu, dif!

Just not brakes, and fuel pump. I want to do the fuel pump tonight that's why I made this thread so I can see what way people think I should do it.

i see, well i would just do fuel pump then, from what i have heard the factory fuel pump would flow more than the injectors anyway.

Ok so I'll just add the pump with no fpr, it shouldn't overfuel with standard injectors?

I have seen post about wiring or something briefly, do u need to rewire it or anything else?

If so could u post a link, cheers

      Turn signal wiring question

      Convert to dual filament bulb   FWIW, it will look odd - I dare say a bit dumb as it looks like your flasher relay has shit the bed.

      Possible swap on R34 RB20DE NEO?

      By GTSBoy · Posted

      If the RB20 box in the car is a push clutch, then yes, you will need to deal with the pull clutch on the turbo box. You either buy a pull clutch and don't use the old one, or you do the things needed to convert the turbo box's clutch arrangement over to push. Which is a bit of a f**karound. "Making" a custom tailshaft is the easy part. But you will need to source the front clip yoke - the bit that goes into the output of the gearbox. These are not as easy to find. They are out there, but they don't grow on trees the way that they used to.

      Indicator bulbs are way too bright to use as a "corner marker" (we call them parking lights too). Sure. Go ahead and do it. But realise that you wil need to come up with all your own wiring to do it, as no-one will have a standard howto worked out for Skylines. It's just a matter of abandoning everything that Nissan have done and starting from scratch. You'd probably be better off retrofitting tailght/brakelight globe bases into the front indicator housings and using the taillight circuit for your corner marker and the brake light as the indicator. You'd need to work out how to kill the marker circuit while the indicator is flashing, otherwise it won't flash on-off, just bright-less bright.

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance
