Pics ARE ON THIS THREAD (http://www.zilvia.net/f/showthread.php?t=158620)


I was told that the 20 was the same as the 25 so this Greddy Intake (http://www.jgy.cc/RB20DETparts.htm) should work if that is the case!!!!

I assume you mean 6 cylinder vs. 4 cylinder

well the 6 has a nice deep grumble IMO and roars up top

oh and the hot side is the same as an Rb25 the cold side is a little different i am sure you can custom make something if you really want. Meh 20's sound good but they are weak down low. Have no torque and the tranny is also weak. I am ditching mine and making a frankenzirra 3 liter monster.

Yes but the KA24DE is an inline 4.... Thus the question of sound difference....:bigok:

Dude, its not about the 6 vs 4, its about having an RB, if you ever heard one, they are the sickest sounding engines in the world!!!
even a stock exhaust on an rb that is tearing it up sounds sick, straight up evil suction sound!!!lol
