I am planning to buy an HKS TO4R single turbo for my FD. The new car only has 4k kms on the motor. Have been running power fc, full exhaust system, twin power, Greddy SMIC.Also have access to a good power fc tuner. I was wondering the stock motor will hold itself at 1.1 bar of boost and will I make good power without any porting? I would love a custom motor, but my budget will not allow it at the moment.I am hoping to get around 450-470hp at the flywheel. WIll I also need a fuel surge tank and what size injectors? Any advice from experienced FD owners out there will be useful.Thank's guys
