I currently have a v2 with v4 intake manifold conversion, yellow injectors, possumlink, vf34 turbo, front mount, fuel pump and line upgrade, etc etc. I think your decision of where to go with your car should be based on how much effort you want to put in. I love my car and i love the journey ive taken with modding it and what ive learned in the process, but if you dont have a bunch of money and a surplus of time and patience id suggest just stick with the td05 with 90 degree inlet or sell the car as is and start with a later model platform to build on because this makes things heaps easier
