I was lookin at a pic of the RB26DETT and i noticed something. Does it have ITB's cause it didn't look like it had a TB on the black manafold.

what about the 25? The 20 is conventional from the looks of things...

ITB's +turbos. Now i know why it's such a bad motor... and why it shounds so good!

ive seen dyno tests of an rb20 with and without the GTR throttles. it actually lost alot of top end power with the gtr setup, although it did boost the midrange TQ a bit. sounds odd huh?
