Hello I have a rb25 turbo with I believe to be a rb20 wastegate the turbo was given to me so I dont know much about it.  The issue is that I think that the wastegate isn't opening all the way it feels like it has a good amount of preload on the rod.  When I open it by hand it only opens about 1/2 of the way and the same if I hook up air to it.  My question is that shouldn't the wastegate open the fully?  Nothing is fouling (rod or WG).  Also last thing to add when I take the rod off the wastegate can move in the full motion.

Really? Ok I’m just new to the skyline stuff and turbo stuff just wanted to make sure this is ok.  Thank you 

Very normal. Were you having any issues with how the car drives that made you think this was the cause of the issue?

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
