a little advice.
 

hi friends, i am new here and this is my first thread.

i am a great skyline fan. and i love the r34 the best. i was wondering if anyone has the complete stats of the vehicle. also i own a 1999 bmw 523i. i dont know much about the modding scene nowdays. so can you guys just tell me anything that i could do to increase power output. something cheap for now. i have been told to get a k&n high flow filter. and mod the intake manifold. as well as the headers.

thanks dudes..
