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

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
