hi i currently have a lil problem with my injectors and fuel rail, i have standard injectors and fuel rail on my r32 GTR and i have found fuel leeking at the top of the injector beetwen the o ring and the fuel rail. does anyone know where i can find these o rings? i have replaced them with some others this mechanic guy gave me and i think there worse than the originals? is there any secrets in fixing this problem? ohh and it usually leaks the worst when its just sitting idoling not when its reving or under load.

thanks

Not sure where the 18 seals number comes from, but on an R32 GTR there are 6 injector-to-fuel rail O-rings and 6 injector tip seals (Nissan calls these 'insulators'). All these are about $6 each from Nissan (trade - that price was valid a few months back when I did mine). The tip seals are also available at injector specialists and they will also have O-rings (of course), but I found that the aftermarket type wasn't 'quite' the right size and that might be why the OP is having trouble with the one's the mechanic supplied. In any event, do them all if anyone is going to the trouble of taking the rail out - a leak in that area is not something you want to live with.......

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...

      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?
