I just got this throttle body from the junk yard, i figured since it was the q45 for some reason i figured they were all the same. Now when i got home and looked at the pics i see some major differences than the one i got. i want to know if i can still use this on the greddy intake manifold on an rb25?

Here are some pics:

I not sure but, would you really want to with all the extra junk hanging off that thing. The one you should have got looks like this.

Yea there are, its for cruise, emissions or idle one of those I don't remember heh. My friend ended up getting one of those and hacking the extra butterfly off and the extra stuff and it works great, but that was one a very customized honda.

Id return it and get the correct throttle body if your not to comfortable hacking that one up.

The thing is i cant return it, they dont allow returns for the throttle body. oh well waste of $45

i was so happy when i saw it because they have like 20 more Q45s but all of them were missing the throttle body.

Thanks for your help

That throttle body is for a Q with traction control. You need one without.
