Wastegates are internal on the turbos hence there are 2. You can upgrade the actuators. These control the wastegates.

They are removable and can be replaced with adjustable ones. Garrett and HKS ones both fit. There are probably other ones you can get, that will fit.

standard and n1 turbos are internal or integral wastegate, which means the wastegate is integrated into the exhaust housing of the turbo, so when you upgrade the turbos the wastegate on them will already be the right size to suit the turbo.

external wastegate turbos have no gate in the turbo itself and use a seperate or external (hence the name) wastegate mounted somewhere on the manifold

when you say wastegate please clarify what you mean

do you mean the spring actuator rod (most people refer to this) - this controls the minimum amount of boost you run before the wastegate opens

or

do you mean the wastegate size itself - this bypasses pressure off the housing and maintains effective boost control

Well yes i realise that Jono :P - but WHY does he want to upgrade them as i said.

Being able to or not doesn't tell anyone much at all.

Perhaps there is something the OP has been told by a mates mate that he needs to do to fix some issue/enhance performance or anything else weird and wonderful that can occur after a few beers down @ the pub :)

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
