Hey Alfamax, interesting project! I've been trying to gather info on 1.4 TDI builds to start my own project in a year or so. The best I've seen so far was 180hp, but this is even better Lovely colour too So, you're saying the gearbox is stock, apart from the 5th gear being swapped out from the 90hp Ibiza (02J gearbox?) Are you also using stock driveshafts? Have you got more info on the clutch (any links)? And how much torque are you putting out? How do you find this turbo in terms of lag? do you have any boost logs you could post? Kind regards, Ash
