Broken Exaust Studs

Hey guys,

I picked up a set of extractors for my R31 and when tightening the bolts up after putting them on, one of the exaust studs broke off from the head, leaving the end of the stud in the head. I left it out and started the car to see how it went but it just started blowing smoke from the head because its missing it. To my knowledge this is a common problem, i have new studs but have no idea how to get the old one out. Does anyone know a technique to do it or should i just take it to the local exhaust mob?

Any help would be awesome! Thanks!

only the brave or very skilled take on the removal of broken studs, you can do more harm than good if your not carefull, suggest you take it to an exhaust workshop as they would deal with these on a daily basis

na its easy man..

just drill a hole into the broken stud,

get one of those star shaped torque spit on the end of a half inch extension

make sure its a bit larger then the hole u drilled so its a tight fit

hammer it into the stud, then use a ratchet to undo it

done it couple of times now and its pretty fool proof if u take ur time

But if it goes wrong and you drill to far through, not dead centre, or snap the easy-out in the hole then your pretty much stuffed. Id take it to a professional if you've never done it before, purely because if you stuff it up, you might have to pull the head off.

If it was something less important I'd say sure go for it, but yeah. The cost of getting the tooling and the chances that it can then go wrong, your much better off just paying someone to do it

GTR_JOEY, your a champion! Did it with a torx bit, successfully fitted but its getting lots of smoke coming off the extractors. could that just be somesort of coating on the extractors or do i have a new problem?

      They’re so great that I know of someone pulling one out to go back to a sequential

      R34 GTR Front Diffuser/Guard Liner questions.

      By Kinkstaah · Posted

      Hello everyone. I've recently started the research into R34 GTR front bits and running into eye watering prices. On the plus site it looks like some places make 'replacement' fender liners for these cars. At eye-watering-but-less than stock prices. I also noticed there's plenty of diffuser options available too. What I would like to know is if my following assumptions are correct. 1) The OEM guard liners are actually only 'half' the liner. They go together with the OEM brake vents which are a separate item which looks to be quite a large 'panel' that is part of the liner. The GTR bumper has bolt holes along the front. I assume the ones in the vent correspond to the ones the OEM liner does not have (circled?)   2) The V-Spec front diffuser supplants the brake ducts in the above item. I am assuming these still work with the guard liners as there's no alternate part that I'm aware of. I don't see how they go together, so I'm making the assumption that they have to, somehow. I know the center splash guard is different on the V-Spec (and is the price of the damn diffuser alone). How does the liner interact with this? 3) There's alternate front diffusers that do away with it all. Annoyingly, a lot of the clones and CF different ones... have no brake ducts on them. I like the idea of them though. My brakes get hot on the track. These alternate diffusers are a lot cheaper than plastic splash guards. I'm assuming you don't have to/aren't supposed to remove guard liners to run a diffuser. I suspect that quite a few people actually do not run the guard liner because with a front undertray you're getting a lot of 'splash' guarding anyway, and most people remove liners given they're probably running a pretty aggressive setup with a diffuser at the front. It would also be nice to know if anyone has ever run the 'reproduction' guard liners and know whether the fitment is OEM quality or "OEM Quality". Example: https://www.ebay.com.au/itm/356254671561 https://carbonetics.net/products/nissan-skyline-r34-gtr-plastic-front-wheel-arch-set Is this knowledge still around?

      Really, effort is pretty low. You hand fistfuls of cash over to someone else and pick it up when done...   And at least this shitbox isn't drinking coolant right?

      Cold compression test after rebuild... should I be worried?

      And most chargers that most DIY people own would put bugger all power back into the battery between cylinders. I've always done it with jumper packs/second battery connected. And that's on any car.   Because race car, and wanting the lightness.  At least in an R33, putting a bigger battery in can at least help shift the weight balance backwards

      OR, Tell the Motec to STFU, you said shift, so try shifting! But then yes, I agree, more sensors needed to. Put either a wheel speed sensor, or a diff speed sensor on it. Then get an input shaft speed sensor too. (I say input shaft speed, and not engine RPM). This way, you can now also log and see if the clutch is slipping (RPM, vs input shaft speed), and you can calculate gear (Input shaft speed / Output shaft speed). At least then if the gear position sensor fails you have a backup. And realistically, the Motec should only worry about what gear you're in for the parts where I'm assuming you have some power management strategies in it for the lower gears. (IE, lower boost, maybe different throttle curves, different ignition curves, etc etc). But it should stop it shifting. Pull the flappy, that f**ker should just attempt the motion! Heck, even on a sequential like on a motorbike, you can keep trying to kick it up a gear all you want, the physically part of the box takes care of not being able to loop the whole way around the box! Only part you'd have to worry is how it gets to reverse.  But that's on the driver... An R32 shouldn't be so smart as to try and override the driver on a gear shift
