How to gain more torque, without spending shitloads?

[jdmTYPE R]

a shorter final drive or even different gear set (for example , 3/4/5 in a B series setup) will reap much more benefit than any CAI , header or even full tune will give. Period.

i got this setup in my car stock motor with a FD and gearset it does rev up lil quicker but does not as quick as a I/H/E and tune....but yes gearset r good but its just anoying that u need to change gears to quick..specially on the streets... I/H/E and tune = close to the same price as FD+gearset+labour and if u can do both it wil be a really fun track and street car+reliable.
