Only one turbo model with a single turbo then shell
sometimes referred to as a 25GT-T yes...because it has a 2.5 litre engine. Thats all that designation means.
Do your homework. Visit the "new to skylines" thread. And maybe look on wiki too if that helps.
And its one thing to be able to drive a turbocharged car - we used to be able to do that in Vic too, when I was on my P's.
BUT.
There may be a restriction in place like the old 125 kW/ton rule we had.
In which case a GT-T or even a GTS-t (33) are still out of your league.
This is where research - not just into the prospective car, but the law too, comes in handy.
and i totally knew about the GTS, i forgot to mention it. GTS is the R33 equivalent of the GT.
