hey guys i own a 1996 r33 gtst s2 with intercooler , boost controller , 3.5 exhaust ,bosch 040 fuel pump etc etc basically my car is running extremely rich heaps of people keep telling me that everytime i accelerate or back off im getting either clouds of black smoke or flames lol ( altho it looks cool ) iv asked the previous owner what 2 do he suggested a tune but in alice springs there are no dyno's or tuners here just crappy mechanics so im gonna have to go d.i.y,the car was tuned 2 adelaide weather then the exhaust was taken off and left in his shed ( due to cop attention and he was planning to sell it stock ). when i bought it he replaced the flat battery and gave me the 3.5 exhaust. The car idles fine and doesnt misfire it has crap throttle response tho , so im thinking possibly the ecu hasnt realised iv put the exhaust back on it therefore making it rich??? so should i try resetting that? or replace the o2 sensor? or buy a fuel pressure regulator??. and p.s taking the ecu away to be retuned is my last resort

    • Power steering is probably because someone has nuked the HICAS CU and you no longer have the variable power asist doing what it is supposed to. How much boost are you running? You are aware that any more than 10 psi on the stock ECU is just asking for it to go to full R&R (that's Rich & Retard, which is effectively Retarded and Retarded!) which kills all the power. Depending on the exact conditions, it can just be runnign on the fat and stupid end of the maps, then the conditions change, you make a little more boost and the ECU goes into panic.
    • @BuiltNotBought Just as GTSboy said.   If you want driveabilty and more low down torque..keep the stock runners. They are VERY good from a factory. I have them too on my RB25DET NEO and as a GTSboy i have fmic but with stock piping route(i have Blitz intercooler) Iam making around 320 BHP and the car pulls "hard" from like 2,5k all the way to 7k. I have it dyno tuned to mimic N/A power curve and making little less max torque due to the smallbox tranny. But driveability is very great. I had 350Nm below 3k so car feels very quick.   EDIT:  Not my channel but i saw this and i know that is what i want (and i have exactly this)  
    • Looking to sort out a couple of issues on my skyline  It recently was rebuilt, however rebuilder long story short did not give two flying effs about the work he did. So moving forward it's running but I have two persistent issues 1) it has a misfire / lag type of issue (was at higher RPMs but I had a dead piggy back ecu removed which improved it) now it's not as bad but still does it at random, I thought it may have been a boost issue I'm running an older turbosmart dual stage controller, turbosmart told me to try running off gate pressure however it still has a lag at random times. It has New MAF, maf plug, coil packs, sparks, CP harness.. injectors tested and cleaned. Factory ECU. 2) Power steering issue. It is tight as anything. Flushed power steering, rebuilt my pump because the bearing was shot. Flushed again still tight (mainly when parking and going slow into my driveway etc)  No kinks in hard lines, replaced the lines I could see had cracks. Still tough to steer.  I was told to shim a coin and place into the solenoid plug? Is there anything else. My steering angle sensor also has a issue. It's a used one I replaced, does it need to be calibrated? I feel like I've tried everything and this car is my voodoo doll.   
    • Holy shit... wow!!! I totally missed this
    • One main filter. Each tank has a prefilter to keep rocks and small children out, then the big main filter that also does water separation. Clogged the first one so bad it was like a rev limiter at 3200rpm. Literally just like dropping the throttle off and maintaining rpm!
