I think turbo+nitrous could be too much stress on the engine depending on how much boost and shot you run . say a well tuned 8 psi and a 35-50 shot on stock internals should be fine , cools the mixture and spools up that turbo , just don't do all that in first gear or shift hard doing it.
My current setup includes fully built engine , haltech , custom turbo kit with a laggy turbo , custom fuel system with 8 injectors and a wet NX kit . I'll have pictures up as soon as the car is tuned and dynoed . I'm thinking about using the nitrous after engaging the gears to help spool up the turbo that unspooled because of "slower" shifting to save the gears , get it ? hehe
