Hi all,

Just after a bit of advice, The car is a GTR R33 Skyline.

The items that are fitted is

N1 Turbos

exhaust - Just fap front pipe, highflow metal cat and cat back Kakimoto Regu 06&R.

Blitz SUS Pods

Trust FMIC

Have bought ready to install....

Greddy profec 2

Tomei Cam gears...

and

Power FC and controller

Standered fuel pump, injectors etc etc

Should i change the fuel pump? or injectors? Will the stock GTR items be ok? If need to be changed what would surfice?

Should i look at adding anything??? I want to do as much as i can before the tune so i know it'll all be right.

Just wondering what COULD be expected from this set up??

Thanks

You need both before installing the PowerFC or you'll be wasting your time and money tuning it. You'll max out the injectors before making any meaningful power and the workshop will most likely tell you what everyones told you already.

upgrade your fuel system....

Injectors and fuel pump will go to about 270kw - people say 300kw but it never makes it to there as the are old and tired

I would personally go some bigger injectors and also a new fuel pump - NISMO/TOMEI etc

You've come this far so you might as well put everything on at once and get it all tuned together otherwise you would be just wasting money going back later for more boost + injectors & fuel pump

Yes - Although the 040 might require you to modify the cradle to make it fit - had to cut the bottom of the cradle off in my GTST

TOMEI pumps go in way easier - use the stock fittings/mountings etc and come with new seal and shit

Yes - injectors are piss easy in GTR

there is a DIY somewhere as well

Also with the fuel pumps, all the nismo 276L/H, HKS 280L/H Tomei etc etc all around the same price etc So they all around the same??? or are any better than others??

you might get away with one of those up 350rwkw maybe..yeah yeah I know heaps of ppl are making that on standard pumps blah blah blah...its about how much power you want know and in the end run, sure you can use it as a lift pump in the next upgrade but then that means another tune and more $$$ wasted...just do it rite the first time and be done with it, run new fuel lines like 3/8" lines again ppl say standard is fine but think 3/8" or 10mm is 20% bigger in size than standard...

At the moment greenline has a special on SARD injectors, so i was thinking some 700cc. Will they do the job?? As there the same price as the 660cc ones

Nismo and HKS are better pumps than Tomei. A few ppl have said Tomei's lose voltage at high RPM and the engine leans out.

GET the pump and injectors. As soon as i cranked the boost (from stock to 12psi) the pump started to die.

Pump change is a DIY job, i'm not a mechanic and i got the old pump out easy. Injectors give the DIY sectin a read.

Get injectors that suit what you need from them. No use getting 1,000,000cc's when i.e. 660cc will suffice.

Don't put a junky Bosche 040 in your GTR if you want to make good decent power and reliably.

Get a Nismo 275lph @ 72psi pump. It will fit it like a glove and require no modifications. Oh, and you won't have pickup issues either.

excellent thanks guys thats the info i was after!!

Glad there both a DIY job, will search for the info...

Ill get a price on the nismo 275lph and the sard 700cc injectors. cheers guys.

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂  
    • Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
