Hey guys, just purchased a 2000 r34 gtt and am pretty sure something isn't right with the waste gate or turbo. Car is pretty much stock besides a race pro inter cooler and 3" exhaust from turbo back running on stock boost (what seller told me). when accelerating , even at low revs my boost gauge tends to spike right up roughly around 18psi according to the stock boost gauge but doesn't feel like it and it sounds as if my wastegates venting the whole time im cruising on the throttle. Any ideas on what to suss out first? am a newby to boosted cars tho if someone can point us in the right direction I have no issues fixing it.

all sorted. Just my conversion from kpa to psi was a little off :P

it does drive well and is real clean. Very happy with the buy.

The boost gauge sometimes doesnt work at all while driving tho, then it will kick back in all of a sudden?

Same thing was happening to me there is a post somewhere on the forums about it. Ill try and find it am pm you

Pretty much it is the signal sender unit A little black rounded box in the engine bay on the drivers side near the Master Brake Cylinder

Take it out open it up and re-solder the top 3 big solders on it.

I did this an it hasn't failed since

Other things are hoses and the such so maybe check those for cracks and stuff, but that was the fix for me..

    • I haven't....but a poorly made one would terrify me. Surely a good second hand one is the go, as they don't work hard and no-one wants to keep one after they are finished with it A big consideration would be the weight of the shell you are putting on it....is it a fully dressed chassis or just the body
    • Not stock. All remade. Mostly looks stock because the pipes run to and from the standard holes in the inner guard to get to the return flow FMIC. I'm not sure which question you're trying to ask, because it seems like "stock position" vs "stock position".
    • Hey, it's a GT-R, it's just as significant a moment as mine😁 It's not ideal when things are uncertain; I'm the type of person that always has a set plan for things in life so being unsure of this plan puts me in a weird place mentally.
    • Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?
    • Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card style AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had no flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
