It actually gets there pretty instantly the 4cly turbo diesel kit will work well with that vehicle. You can use r DO3 nozzle. You will activate at around 4psi or .27 bar. Or close to 1500rpms this will give you big hp and torque gains to your redline. You can mount it just prior to the intake or go pre-turbo with it. It's all up to you. Either way you will have good power increases and beter acceleration and you will have significantly lower EGT's
Not the best place for a intake, Right over the turbo, That thing much get heat soaked pretty good. A intercooler will not help with that, Like I said your going to get a major bump in power do to the bad set up on that vehicle.
