see the problem with 4x4's is the gearbox tends to shit itself when u up the power/torque......but having said that aslong as u dont launch them or rag the fuck out of them in 3rd they do last..........my advise for a very good road car would be do ur gasket and sell ur T4 and put a t34.48 on it....stick in some bigger injectors than greens seimens 55's or light blues and get it mapped to about 28psi spike and hold 25/26 psi......this will be a mint road car that shouldn't give u to many problems (circa 360bhp)...............
