Gtr Front Pipe Exhaust Leak

Hey all

Went for a run in my gtr last nite, pulled into the servo and could hear an exhaust leak, so when i got home from work 2day i pull her out of the shed while cold and started it up. Started feeling all around the cat, than opened the bonnet and flet around the rear turbo and rear turbo dump pipe as that was all i could reach. but it didnt sound like it was coming from the engine bay, so i got a torch and started looking round under the car as much as i could before i put it up on my hoist. I wanted to find the leak and buy the gasket b4 i pushed my old mans project car off the hoist and screwed around lifting it up.

Prob is the leak was coming from this thing, never seen one before on a front pipe. But sayin that this is my first turbo car so i dont really no. It dosent have massive holes in it, but it has prob 2-3 3x3mm holes as far as i can see with the car on the ground. My question is what is it? is it like a front cat or somthing? Can i take my front pipe off and just get a pipe welded in there instead? or is there any other way to fix it?

thanks all

ps dont mind the red silicone, forgot to wipe it off, the other day when i put it on my gearbox oil plug after a oil change. :P

just get a pipe welded

there are plenty of solid ones going around that are worth big bucks

i have one running with zero dramas

make sure they evacuate the pipes before welding orelse there will be left over welds on the inside of the pipe

alternativly ones from ebay are like $250, upto you if yours are worth repairing

my one is BeeR i pritty sure from the lil plate under it. I cant believe its leaking from there. I under stand were nismoid is coming from but, when the engine twists up, it will want to twist the exhaust, maybe thats why its worn out. Sucks ; (

any exhaust place should be able to weld a new flex in for you pretty easily mate

Have had plenty of flexis f**k up and fail on high-power FWDs in the past .. they leak and stuff all too easily ... (tho in that situation for me often seems to have pointed to f**ked engine mount that's caused it) .. Easy fix for exhaust place tho to weld a new one in.

yea im guessing thats where the prob started. the car had new engine mounts put in just b4 i brought it, 2 months ago. so that would have been wearing it even more. ill just pull the fron pipe off over the weekend. All i gotta do is find a decent Exhaust shop that i no will do a good job on it.

Taking the front pipe off and fixing the flex pipe whenever it breaks (which would be really rare) is much less stressful than replacing broken turbo/manifold studs and bolts and turbo gaskets with a front pipe with no flex-pipe (Trust MX comes to mind).

yea thats what i plan to do. Just dont want to take it to some dodgy exhaust shop and they weld it up all shitty. or with the bit that bolts to the turbo on the wrong angle or anything u no. its a BeeR front pipe there worth about 700bucks im prit sure.

dude, it's pretty easy. just take it to your local exhaust place. they will cut out the current flex and weld in a new one. it's not rocket science. and being that it's only one side of a twin front pipe the flex joint is not even that large so it shouldn't be too pricey.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.

      I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
