hey I'm newish to the forum and have bought a completely stock, bf xr6t mk2 ute build date 08/05.. pretty sure what I want out of it, from what I've read I'm pretty close it.. was thinking cai some aftermarket one still researching, pw intercooler, high flow cat, larger injectors and full tune.. brakes are going on in the next few weeks and lowering.. is 280- 300 possible with this set up ? was looking at spending about $4500 on the motor.. am I being unreasonable?
