Why do people keep buying shit and THEN ask about it? Yes, there are problems. First off, a throttlebody spacer is totally useless unless you plan to use it for nitrous injection, which would make a supercharged motor explode. Secondly, dropping the pulley size with no supporting mods will also make it explode.

x2 alot of money wasted because you didnt research and potential to blow your motor.

your gonna get a huge amount of kr with that small of a pulley you probaly will lose power.

What is your pcm programmed too 91 or 93 octane fuel?

Get a
ubend delete
colder plugs
colder thermostat
then consider a smaller pulley

i know that a spacer will not increase your power as far as a whistle i couldn't tell you. Im not into random whistles in my car.

Also don't be surprised if the weak transmission blows with the pulley drop. so be ready to drop some cash on a built trans

Nobody is getting hyped up, real or not, we are just trying to prevent bad information from being spread.
