everybody who has a big power starlet brakes them after a very short time of doing it. ive been in a 500bhp skyline and ive been in a 300bhp starlet and i can easily say that the starlet aint got shit. my choise would be the liner all day fella but as already said id drop down to either the 32/33gtr models much better than the gtt. and yes they cost more but this insurance being more is abit of a myth ive managed to get mine on my evo for exactly the same as i was paying on my v! the tax is more and the fuel cost but if you want a better car then these are the fall backs Ben
the livesports lip kit for the gt is the best available imo for the gt, ever since seeing pics of tobys old gt with the kit on it ive wanted one but i had a bloody v lol
600bhp for 2500 should be hard man. for that you would need a forged lump, which is more than 3k already plus the turbo setup for somthing around that figure would be a gt30 and the ams kit is about 4k on its own.
