I am getting a redtop for my 240, I wanted 2 know if there were any other throttle bodies that I could use insted of the oem unit???? Or would I have to bore it out?? I know the q45 throttle works with the rb25 so what is an option for the sr20?? all help is appreciated

 

i saw on some austrailian web site that the throttle body from a na sr20de is a little better and you'll get a few more hp and better lower end. derect bolt in is also nice!

 

why do you want a larger throttle body? if your just now getting the sr and dont have it in yet, you shouldnt need it. i mean you havent even gotten a bigger turbo yet or have you. save your money and get something that will help more. i have a stock throttle body on my sr and its fast as hell with turbo upgrade and injectors. all im saying is its not needed. i would put that on later when youve exhausted almost all your options to make your engine get more power.
