Dying R33 GTR rear turbo? - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Olly-R · 28th September 2008, 04:00 PM

Hi i'm new to my R33 GTR, but been doing GTi-R's mine and other for years. Bought my R33 GT-R a month or so dead and off the road, cracked head already off and a bucket of rusty bolts,

Took the lump out complete and fitted a complete low mileage engine (turbos inc the lot) (with restrictor missing from turbo solenoid as it was when i bought the engine so obviously been pushing more than bog stock) all good, been spanking it (stock gtr with exhaust/filters/hard pipes/apexi cooler and a bar) around sideways and like love it 500 miles of fun, firstly noticed leaness on my wideband, so clean both mafs wich were dirty cleaned and all good 11.8 afr @ wot. But intermittanly when downchanging and boost hard can hear like a tinging noise/pinking hmmm? and now sounds like the rear turbo is blowing very slightly and rattling on rev up from idle, i read on here the rear goes first could this be the start, i have some spare turbos so thinking will fit the front one to the back and go from there? what ya reckon chaps?

Check your exhaust and manifold gaskets and also the nots/bolts to make sure nothing has worked loose.
If u are getting a pinging noise i would check it before booting. What fuel are u using and does it have a stock ecu or aftermarket?

Will do fella tomo, but i always aim for the worst case, but hopefully the turbo just worked loose on the manifold, and the rattle isn't pinking and just the turbo being loose or what evers left of the gasket ;-)

Could be just the turbo heatshield (assuming it hasn't been ditched)?

How much did you pay for turbo gaskets??
I'm going to be changing my turbos pretty soon but was quoted some crazy numbers for gaskets..

TT

manifold to head gaskets are the worst, but manifold->turbo are normally about a fiver a pop same as turbo to elbow.

The small paper gaskets you can normally get a full set in a box for ~40 maybe? that will come with fresh copper washers for everything too.
