hey guys.....sooo..today was the day...went to pick up my baby after an awaited time.... she got 249.2rwkw :( BUT!... tuner tells me i have an exaust leak... which i assure you was not there when i took it to em'.. so i bring her home and sure enough on the way home its like driving a tractor...now i have had this once b4 and it was my high mount manifold... but i just jacked the car up and i dont see any holes on the manifold at all.. i noticed that the gaskets for the ext. gate are lookin kinda burnt... so guys can everyone (its within the engine bay) just tell us the more obvious spots for it... could it be turbo to manifold gasket?? if so how can i check without pullin the hole lot out...

any input is awsome... thanks everyone

Same prob for me yrs ago, same spot.

The 4 bolter gasket between the turbo and ex manifold.

Only takes a little to drop out and you have a leak, and it's hard to see all 4 sides properly

Get a genuine Nissan one too if that's the case, not a soft ebay job, cause they are soft...

when the car is dead cold start it and feel around for the leak.

You have about 1 minute before it gets a bit too warm

With a high mount you have the manifold-turbo gasket, manifold-gate and turbo-exhaust.

It'll be a big leak so very easy to find.

soooo shortly after posting i went hunting for the leak.....found it at the manifold to wastegate join.... gasket was blown to shit and back... i have a JJR ext. gate..and man they are the worst design ever... like... you cant even get the bolts done up properly cause they rub agaist the body of the gate...stupid..any way... replaced them with some nice metal gaskets :D:)... took her for a spin... and sure enough.... the tractor returned...both gaskets blew out... so i bring her home and pull off the gate again.. (worst four bolts of the car) chucked in some metal gaskets again from an exaust shop... just finished then...started her up and can feel leaks again :ninja::)... i think the flanges are either warped or there is something on the flanges that leakin it...so ill give her a drive but can almost guarantee that it will blow out again.... junk junk junk....

thanks for the input guys.... champions

Thats the 38mm gate?

The genuine hks is no better. I've forgotten the number of times i had that bastard of a thing off and on and cursed the design. I actually had issues with the outlet though, never the inlet.

Get the faces machined flat and install some studs on the manifold. Get some narrow nuts (12 max, 11 preferably) and a 1/4 inch drive socket set with wobble attachment. I ended up buying a sheet of exhaust gasket maker and made my own as the thing was off so often. I never had leaks. But the head/manifold and gate outlet leaked after every track day....

    • 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.
