planning to purchase skunk2 throttle body on d15b7, would the throttle body make a major difference in hosepower, intermediate difference or no noticible difference?? also how much should it cost to get this throttle body installled from a shop?

 

theyre really easy to install man you can probably do it yourself

as far as a hp boost its not realistic to expect much. More air gets in though, which provides for slightly punchier throttle response. It does what it does, but theres better things to spend money i think

 

not worth the money at all, you can about buy a whole JDM D15B swap for the price of that throttle body
