Would get a lot more replies if you put it in the maintenance section.

you will need turbo to manifold gaskets, exhaust manifold to head gaskets, turbo dump pipe gaskets, copper washers for banjo bolts, permatex high temp silicon gasket maker and i would also budget for replacing all the studs and probably removal of a couple of broken ones.

You may be able to re use some of the gaskets by coating them in the gasket maker but if its a car your keeping and you dont want to have to do this all again in the near future it might be good insurance to invest the money the first time.

Not sure how hard it is as ive only ever done gtst which is pretty easy.

might be worth getting the manifold 'mating' surfaces machined flat, just in case they are warped and thats causing the leak

just a thought anyways

Not the right place to post this mate so I'll give you an idea before the moderators close it... You most likely have a broken stud or two and a warped manifold so to save some cash you can do it yourself ( from what I've heard you could pay as much as $700 for someone to do it ). You'll need manifold gasket ( I have if you want to buy ) which are about $70 at best, copper banjo washers, turbo to manifold gasket and turbo dump gaskets ( about $50 at best ) you're best to replace all the studs while you're there because they commonly break ( $30 from nissan dealership ) and to do that you'll need a right angle drill attatchment ( about $15 from bunnings ) and an easy out set ( anywhere from $5 for Sontax which will do the job no problem, to $50 for brand name set ) also you'll want to get the manifold machined ( $60 ish if it needs it, which it most likely will ) as well as all this you'll need a decent assortment of tools and a can of 'freeze and release' will be your best friend when undoing exhaust bolts. In a nutshell you need to take off the turbs then the manifold, take out the studs ( I had 2 broken and another 4 broke when taking the rest out ) drill/easy out the broken studs, clean up the gasket surfaces, replace the studs and bolt it all back together with new gaskets. There are write ups on the forums and if you work on your own cars, and have a fair idea about mechanics, then you should be able to do this in a day, maybe two depending if you get the manifold machined in one day and also depending on how easily you get the studs out, so probably allow 2 days off the road. So if you're confident you can do it then you should budget for about $250 - $300 tops. Do a search on replacing studs, removing turbo and replacing gaskets and you'll get a fair idea what you're in for and how to go about it all properly. Hope that helps mate and all the best if you tackle it yourself Feel free to PM me any questions

Ps - Just noticed you have GTR so will most likely be more involved and more expensive
