Ah there it is:D thats a pretty small wastegate, but with such a huge exhaust housing it would probably be fine, so where are you going to fit it on the stock manifold? Or are you going to set it up like Rob77?

With a turbine housing that big, it would probably be a really good idea to get a killer manifold and some cams in there or you probably wont start boosting till 4th gear:p its a bloody monster!

Yeah i said to him you are gonna run into all sorts of dramas...but yeah he said he wants to use the standard manifold and different cams. It might be a good idea to mount the wastegate on the turbo. But i don't know what he had planned with regard to that. I'll have to find out.

why have such a huge turbo with such a crap manifold, get a tuned one and you will notice the difference, like running 21psi with stock manifold and then drop to 16psi with a tuned one is a big difference especially when u consider that 5 psi was going back onto the valves, u can run more timing and get more power with less boost. turbo looks great otherwise.

Dosent matter what manifold that turbo would not suit a rb20, mine is on the limit size wise and is only the smallest type to4e, it makes fullboost at 4300rpm so yours would be 5000+, not good with little of boost.

Also the turbo would be a tight fit in the engine bay bolted to the stock manifold, so check that as well.

What other mods has he done to the car, in a few months i will be selling my kit, trbo, manifold, wastegate, cooler, pipes, chipped computer, z32 afm, everything to get 230rwkw and 12sec qtr times, for a lot less than would cost to do new.

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • 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)
