my advice is get a r32 gtr mate...you will never look back..ive got a r32 atm and the cossie wch i got recently..512@1.4bar if boost with some hks 2510s...and a fair few other bits as well....spent loads of money on it...its addictive!
tbh GTR prices have plummeted they are really cheap now..you can get something with stage 1 mods for like 6k and it will probably be ok..obv near 10-11k and your getting yourself a mint one low miles..excellent bodywork etc
only problem ive ever had with my GTR has been with my battery in nearly 2 years of ownership and i bought a new halfords battery and never missed a beat.
not going to lie the petrol is awful...cost me nearly 1/4 tank to get like 25miles...so its quite painful!
get on the gtroc..we are a helpful lot!
