Hey there guys, Thanks Alan i found this really important. But i thought i would make people aware of this, Be VERY CAREFULL when trying to remove the fuel rail and injectors out. And look at the end of the injector and make sure all off the 4 prongs or claws on the orange pintle cap are attached. Because i am currently sourcing the 6 pintle caps and there not easy to chase down because they are so wanted :starwars:

Hope this helps Cheers Rob

Great DYI mate

Installed my Tomei 555cc today which replaced the std R33 GTST injectors.

I didnt remove the AAC, didnt get in the way at all for me. nor did the FMIC piping.

For cracking the injector cap screws i used multi grips.

To get the injector out of the rail i used a flat head screw driver and slipped it under the injector plug then twisted the driver to lever it out.

when i changed the power fc injector config, i used the following. Old Injector CC / New injector CC x 120 = 82

my power fc was configured at 120% for each injector...not sure why it was set like this but the above achieved a nice idle. i did actually test 66% based on the x100 calculation also...and idle went to hell...

no...it will probably start up and idle ok but soon as you put it under load it pretty much floods it..then plugs will foul then it all falls apart..i tried it once, got around the block but barely made it home..lol

but if you have access to your ecu just find out how to change settings..

really good writeup. i have a powerfc waiting to be installed in my series 2 gtst but i wanted to upgrade injectors first two quick questions..

1; will injectors give me much more power once installed and tuned with the power fc

2;where is the best place to get hold of some injectors and what size is good when chasing 300 to 350 hp?

cheers

Nice write up and presentation, my question is will we need to dyno the car once everything is fitted back?

If you change to different injectors  it needs to be tuned.

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
