The Trust Type R kit is designed to be fitted in the original location, using part of the original piping and mounts.
The pipe attached to the blow off valve in the photo you have provided indicates it was most likely fitted between the plenum and the guard.
More to the point, fitting it to your car is a complete waste of time, the stock GTR bov's are more than capable, even at high horsepower levels so unless you really need an atmo blow off valve to impress the chicks, save yourself the hassle.
