Losing Boost/power From 1 Turbo Only - R33 Gtr

[Union76]

Ideas anyone? Thanks in advance.

Stock R33 GTR (Filters, full exhaust - no boost controller etc).

Problem: After cruising on highway (hot or cold day) notice only 1 turbo is boosting. Turn GTR off, then back on and problem solved - back to 2 turbos. Happens only sometimes. Happened a few times now. No other problems than this.

Looked at afms and connections - seem normal

Can't find any vac. leaks.

Again, any ideas - thanks.

Mike.

How do you know only one turbo is working? perhaps a dodgey wastegate actuator?

Now that I think about it - You may be right, would make sense.......

Anyone else had one of these flog out?

Thanks "Omurru" for putting the idea in my head - off to check it out

Same thing happens on my R32 GTR when traveling long distances on boost. I think it is a safety feature of some sort to stop it for over heating.
