Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason. From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced. Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!

Super cheap auto selll generic ones that are like s shield over any pod

I'm making 525rwkw with this and it has been doing that since 2013, without ever opening the surge tank, I'm probably due to check the socks hanging off the pumps etc Regardless it's fair to say the walbros do the job just fine as I have never had an issue with it. I definitely recommend a fuel pressure gauge, as I did have an issue with the hat on the fuel tank which restricted the return line and made the pressure jump to over 100psi.. had I not had the gauge to spot it straight away I'd hate to know what would have happened eventually I think people have issues using the wrong type of hose which breaks down internally

I have a pioneer deck that's pretty much new that I'm willing to sell. Bought it for my car and ended up getting given another deck for it

If the tyres are mega sticky third gear will go eventually, I have done this three times doing anything from simple changes launching to just a light clutch pump. I run a direct twin plate so there is zero slip. Slip is annoying as hell especially when you've built the thing to have power.

Rear will hang out the guards 10-20mm depending on camber

I run a standard rb25 throttle body and get 525rwkw at 30psi.. so fair to say No need

Radium Surge tank with twin walbro 400s submerged in the surge tank making them silent Depending on the ECU you have surely you could setup a fail safe in case you drop fuel pressure?

is this sold?
