Hi,
I have a 32 GTR and I took the turbo's off my car by myself at home. I'm definitely not a mechanic at all, but I did it. Took 2 nights to do it, about 4 or so hrs each night. I just unbolted whatever i thought needed unbolting
Front pipes where first to come off along with all intake and associated intercooler piping. No idea what was the 'right' order to do things or not, i then unbolted the the coolant/oil lines from the front turbo, unbolted the turbo off the exh manifold, undid the 6 bolts of the exh manifold to block and managed to get enough leverage to pull turbo out with manifold still just attached on studs to block. After turbo and exh. manifold came out separately you can start doing it all again with rear turbo. This ones a little harder, less room etc. I left the manifold attached to the turbo and a little painfully I pulled out all together. undoing the necessary oil and coolant lines were damn annoying (hard to un do!).
I had a quote to pull turbo's off, then put back on with all new HKS gaskets for around $850. So far its cost me nothing apart from the turbo rebuild/hi flow.
Once again, im not a mechanic, never been one Only had a basic socket set with a few little extras connection pieces.
