Sorry Genelle, but No.
A skyline with FMIC, full 3" exhaust and extra boost will get hosed by a stock XR6T, especially if its an FG.
I have an FG, completely stock except for heavy as f**k 19" rims, cheap ass rear tyres, bodged the launch, and still ran a 13.005...
Rolling runs from 70KM/H no way will the 33 keep up...
Not to mention, change just the dump pipe on an R33 and tune it to suit (If you don't retune they won't really run as the ECU is very finicky) and you're now easily running flat 12s.
There is actually an FG dead stock running 12.2 down the quarter. Completely and utterly stock.
On the roll, especially with an auto, they're freaking QUICK cars. Punt it into a turn, sorry to say, but a fresh redo of the suspension (To standard) in an R33 will also get hosed by an XR6T, especially if you add water into the mix.
It's surprising how quick they are, even more so when you make all things equal.
As to the OP in question, I wouldn't bother wasting your fuel against him. You will lose unless he's a dunder clump that can't drive...
