dude you wont be able to aford it. their is no offence meant but unless you are pulling in some big $$$ you are not even going to come close to it thats why you got laughed out loud at. You say you want 320hp is that for a particular reason ??? not sure what gts4's go for these days i guess around $14,000 - 16000 k ??? then a gtr engine another $6 - 8,000 + engine conversion another couple of grand etc etc you see my point their is no way in hell you will be able to aford it. just get a S13 for the time learn to drive it then get a skyline. as i said not trying to offend you but get a cheaper car to run till you get a full time job that pays a decent $$$ i may be wrong but i am guessing you are working only casual too or full time at macca's ???
