Well taking the manifold and turbo, etc may take a couple of hours, but the work on the studs should only take 2-3 hours.

Thinking about it, maybe towards $500 might be reasonable for like all of them and an "drive in drive out" job.. 2 days work isn't really true though. I've taken the manifold off a couple of times -- on and off in about 2 hours.

If you want to save the bulk of the money, take the manifold off yourself, and put it back - then get the guy to tap and thread them. It's probably recommended to get a new exhaust manifold gasket as well (about $120 from nissan).

the studs are 13.80 retail from nissan. and then theres the nuts. about the same.(same as sr20) the 500 dollar price comes from havint to remove the manifold ie r and r the turbo.

then drill and easy-out the studs. if there broken off. also if a few are broken youd be retarded not to repl;ace them all.

so that price is just realistic. two solid days is abit excesive. but 1 day is believable. :P

took pretty much a full day to get mine done. but i didn't have to pay anything cause i know the guy that owns the shop.

i had 2 broken studs, and they broke 2 more getting the old ones out. they have to take the turbo off and oll the other crap thats in the way.

i thought i had a cracked manifold stud not long ago, turned out it was a simple fix me and another guy did at work in like 1/2 hour, it was just the turbo gasket was blown, so we just unbolted the turbo form the manifold slide it off slowly enough to becareful as to not damage the oil and waterline, then took the blown gakset out and replaced it with the new one, we didnt even have to remove the line off the turbo only the 4 bolts that attach it to the manifold, was quite easy.

Um, I've done it a few times.. It's not a GTR.

Well they cost me $2.31 retail - I have the receipt right in front of me.

is that through nissan themselves gordo??

just goes to show how much different dealerships mark stuff up.....

the hardest part about changing the studs is if u happen to snap it off inside the thread, then u are in big trouble bcoz u have nothing to hold onto to screw it out, and they are apparently very very tight.

Well, I just got a couple more quotes and $500 - $600 seems to be fairly reasonable. It is not an easy job removing everything from the manifold etc... Then if any of the studs are stuck, it is a little tricky drilling them out. Machining of the manifold is about $100, studs are about $12 including nuts from Nissan and exhaust manifold gasket is $115 from Nissan. I've found no general mechanics want to do it, only exhaust centres, so it is obviously not the most enjoyable job to do.

yeah i dont think ppl like doing it aye its one of those annoying jobs i guess.

all of mine broke off in the head, so it was a much harder job. if they break off with some of the stud poking out there is a tool that you put on the end of a socket to grip onto them to get them out. no drilling required.

Besides Nissan, where else can I get the exhaust manifold gasket? I'm also going to get my rocker cover gasket replaced because it is leaking a little bit of oil. So anyone know a good source for the gaskets?

I can get you all the studs with nuts for $50 and the gasket for $50 if you like.

The R&R for the turbo and manifold is around 4 hours but then you have to factor in the broken studs, seized bolts, etc. etc. Add 1 hour for each broken stud just in case. Usually you'll get two if you're lucky.....6 if you're not. So say worst case scenario you have 6 broken studs and they all take an hour to remove - remember it's a murphy's world....it would cost you $77/hr X 6 hours + another $77 X 4....That comes to $770 + parts and given that it would be a 10 hour job I would like to have the car for two days just to be sure as well.

Sounds like they are just covering their arse, which is what any good workshop will do.

Best case scenario you only have 2 broken studs in which case it will only cost you around $460 + parts.

That would be great! PM sent.

Yeah, I think so, seems fairly reasonable the more people I talk to about it.

      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
