Restrictor plate, if we have those I need a how-to so I can get it off...I hate being broke and not being able to do anything to my car. If it sounds like something not healthy for the car I'll be the test dummy.
Just get a set of intake runners from a JDM SR20DE, slap them on and remove your emissions equipment. That way it will appear to be a JDM, but it actually won't be..aside from that, I agree with what Serban said.
LOL!! We dont have restrictor plates! First thing I thoguht was NASCAR LOL. Resrictor plates are for carb'd engines to restrict the air/fuel mixture I beleive. He must a a "JDM fanboy" Lol, so he can tell his friends, "I have a JDM engine, its mo betta"! Seriously though, why?
