I've had a v8 91 for around 6 months and have gotten used to the power it puts out. I've wanted to mod it but have always had the thought of getting a manual twin turbo and then moding that seeing as it has more potential in the long run.
I was wondering if there is anything to look out for if you are looking at manual twin turbos. Also, for around 2 grand what mods would be best to increase performance for the twin turbo.. exhaust? intercooler? IFT chip?
