Hey guys,  first time poster,  long time skyline lover. 

I have a series 1 33 gtst, just purchased the car and have a question. 

Have been told its been rebuilt 40xxx ago and had bigger injectors and bigger girl pump installed with a standard ecu.  it shoots flames.. Like hella shoots them..  All the time.

On the jdm cred side of things it's badass but I can't help but wonder..

Is the flames due to the bigger injectors making it run rich? 

With it having bigger injectors,  would I benefit from installing an aftermarket fuel pressure regulator? 

If so,  what would the ideal pressure be or how would I find that figure?

Get a wideband and check the actual afrs. They may be rich or lean but unlikely to be right.

If they are wrong you can either put standard injectors back in or get an aftermarket ecu and a tune (or work out a Nistune solution with an R32 or Z32 ecu.

If your injectors are bigger than stock an fpr is not the way to tune.

I can get an RB20de nistune ecu of a mate,  apparently I switch 2 wires on the injectors and I'm. Good to go,  not to sure though,  I've read a few threads a out it.  

I have been told to get a tuneable ecu to solve this issue and of course just to get better performance in general but wanted a better understanding of what's actually going on.

      What brakes on R34 GTT(Europe)

      By Kinkstaah · Posted

      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.

      R34 Gtt Wheel Offset Advice

      By Kinkstaah · Posted

      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?
