Hey whats up. I have been having a problem with my car. I was thinking it was my spark plugs but I just changed them out today and I am still having the problem. It seems as my boost gets to .7 my car supters like there is something wrong with the mixture. I was boosting 1 before. I have a metal headgasket, aftermarket turbine, wastegate, and many others. I also have 550cc injectors and a GTR fuel pump. I have not done any adjusting of the tuning so I dont know what is wrong. The only I have done is used on base gas which made my car run like crap. But since then I have used off base Japan Super Octane and ran fuel system cleaner threw. Any ideas? It seems like this always happens at .7 boost. Thanks for the help...

Well I fixed that problem but I have another one from something that happened last weekend =(

Well this past last weekend I checked all my plugs and coil paks to see if I could fix the spudder problem. Well I sanded down all the igniter plugs in the coil packs so I would get a even contact because before hole was burnt out of them and it wasnt in the middle. I also stretched my springs out to try and compensate for the shorter igniter plugs. Well I drove my car and it was running really good, wastegate was opening and no spudder. Then my friend thought he could fix why my car idles so high and he messed with the trottle position sensor and the idle adjustment knob on the rear of the engine. Well he messed with the idle adjustment and said that it wasnt working right and that maybe the spring inside was gummed up so I tried taking it apart and putting some choke cleaner in it. Before he said he could turn the screw and the idle wouldnt change very much, that is why I cleaned it. One other thing that was done is one of my springs broke in my coil paks so I have a spare R33 coil pak so I just used that thinking it would be alright... Well when I started to drive home after that guy messed with some of my stuff I would drive and my RPM would just drop and I would have to push in the clutch and give it a good steady push on the gas pedal or else it would die.... Even if I was just driving normal it would cut out... So I drove my car to work a couple of days and it would do it everytime I would go to and from work and it would always be in about the same place going different directions to work. Anyone have any ideas? Maybe because 1 coil pak is a R33 coil pak or maybe something else? Please help me.... Thank you =) and sorry about the novel... =)

Also how do I set my idle adjustment right? and the throttle position sensor? Is there a diagnostic I can do on it?

      While doing my tailgate struts I found some rust. Also replaced my bonnet struts. Such a cool satisfaction with that job.

      Should I use rust converter on this?

      By PranK · Posted

      So I removed as much as I could from both sides. The shop vac did a great job of clearing 99% of it. I got it all as clean as I could and then absolutely drenched the whole lot in the rust converter. Tonight or tomorrow I'll hammer it again. The cavity must be close to 400mm in length and surprisingly I was able to get it right to the back.  I'll quickly reassemble and then pretend I never saw it. I'll post pics (for me to ignore later) soon.

      Help Understand GTT Boost Setup

      By GTSBoy · Posted

      I have always resisted the urge to go silly. 8" wide wheels and street friendly spring rates? Check. (Let's not talk about the steadily increasing spread of spherical joints across my suspension!!) Stock turbo, run at 12 psi? Check. Lasted for~?10 years before it died. Highflow put on rather than seizing the opportunity to go G45. You don't need 300 rwkW, let alone the more massive numbers that seem to be essential these days, to have a car that is already way too powerful and fast for a streeter. ~250rwkW is fine. I've never exceeded 200, although I will sneak up above it if and when I manage to get my finger out and do what needs to be done to use the highflow's capacity. You don't need $10k worth of CF bits glued onto the outside. You don't need razor sharp ankle cutting front splitters. You don't need the car to be 2" off the ground. You don't need flawless paint, mirror finished wheels, brand new indicator lenses, etc etc. All these things just make the car impractical and will cause you pain when they get damaged, which is inevitable for a street car. A few nice additions are good. Good seats are good. A nice stereo is good. A/C is good! (46° on the road yesterday and my A/C is degassed again. Was moderately traumatic driving home!) The main reason I stick with a mildly modified old Skyline is that I have had it for >25 years, the mods are the rolling result of 25 years of things dying and being upgraded opportunistically, coupled with a few "just 'coz" ones. And I hate almost all modern cars. If I was a young buck starting out now.... I wouldn't bother. Cars have a few years left where there is any possibility of interest or fun. Thereafter there will be no such thing allowed or possible. Any time, money and effort spent now on a project would just be a waste.
