Hi all,

I have a 1996 R33 gtst, resently had a problem arure,

I'll try to describe it..

The car hits boost starts to pull then at higher revs sounds like it is goin but its not

pulling anywere near how it should..

The car has a boost tap but only running around 8psi atm.. fmic and cat back exhaust..

I tryed running a straight line just from the actator straight to the cooler pipe (same result) i then tryed swaping the a.f.m (still same) the car was serviced 2k ago, im quite sure all the clamps on the cooler are tite, i replaced the spark plugs yestarday and all coil packs seem to be in good order.. I hav also changed the b.o.v thinking that it could be leaking .. (still same)

So im quite confused as to wat the problem could be../???

I know its real hard to diagnose with out seeing the car,

but just thought id ask the question

Thanx for any advice you can offer :banana:

Yea i changed the fule filter 2k ago as well, and the car was running like it a couple days ago i changed and plugs and the coils seem to be fine not cracked or anything and its still running the same..??

also it seams just b4 in goes to hit boost it hesatates a bit, and again in higher revs more so under aggresive acceleration...???

Umm the plugs are ...... the bloke from aout barn recons there perfect for the rb alredy no need to re-gap them..?? im gunna change all the coils today as well c how we go..??

Another question iz there any advantage to moving the a.f.m to the cooler piping and having just a straight pipe of the frount of the turbo (all with starndard computer) ...???

re-gap to 0.8mm... if weaker coils, higher powered cars, also considering age..

it's a laugh if your getting technical advice from auto barn.. i would look at one of the sponsors on here to get your equipment.. (also for supporting the people that support you)

I recommend Kudos on here as he checked all info and gave reasons as to why choose different items... instead of just reading what the manual states..

well today i pulled the fuel pump out seems to be in good working order, changed the coil paks, changed the plugs coulpe of days ago (gapped at 0.6mm) changed the air flow meter, checked all cooler clamps. changed the b.o.v just in case it was leaking... still same resault after all that ....???

Really running outa ideas...

Lol ahahah good point but im saying like no power dies in the ass bad! iv had a skyline 4 around 2 years i know how it was and how it should be lol.. i would say turbo yea but its not blowing any smoke and if u ease into it, it goes ok it when ur flat to the floor (to quike on the acceleratore) that it stuffs up..??

    • 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?
