Billy Ryan Posted March 1, 2006 Share Posted March 1, 2006 I have seen different throttle bodies being used on the RB. I have also read somewhere that you have to use a 240sx throttle body if you use the Greddy aftermarket intake manifold. I have read that the Q45 TB is a common swap and the 240sx. I have also heard of Mercedes and Cobra TB being used. I was just curious as to what all of you guys are using? What size is your TB? I just wanted to see if there are any other choices I could go with. Thanks. Quote Link to comment Share on other sites More sharing options...

Billy Ryan Posted March 1, 2006 Author Share Posted March 1, 2006 I did do a search. I have read about the Q45 TB. I have read about all of the TB's I had mentioned above. I was just curious about what everyone else is using. I just wanted to see if there were any other choices. I also wanted to see if anyone was using any of the TB's that I had mentioned and how they performed. Thanks. Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted March 1, 2006 Share Posted March 1, 2006 the Q45 TB is 90mm. Yeah, just letting you know that the RB motor is nothing close to a 240SX. The RB25DET GReddy plenum is designed to work with the Q45 TB. Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted March 1, 2006 Share Posted March 1, 2006 Found this on the Exvitermini site, didn't realize Jun made a RB26 plenum for single TB. Quote Link to comment Share on other sites More sharing options...
Billy Ryan Posted March 1, 2006 Author Share Posted March 1, 2006 Thank you 240Z Master. I really appreciate your help. Sorry about the 240sx and Q45 TB mixup. Thanks for the correction. Quote Link to comment Share on other sites More sharing options...
S15 200sx owner Posted March 7, 2006 Share Posted March 7, 2006 I am using an aftermarket billet alloy 80mm TB, see my photo gallery on this site. Quote Link to comment Share on other sites More sharing options...
mrcheeze36 Posted March 8, 2006 Share Posted March 8, 2006 The Q45 TB is actually 80mm (measuring the throttle plate diameter). Quote Link to comment Share on other sites More sharing options...
J Taylor Posted March 8, 2006 Share Posted March 8, 2006 I am using a BBK 70mm for a mustang. Got it off ebay for about $100 or so if I remember correctly. Not sure it is a good option for you though since my intake was built for it. JT Quote Link to comment Share on other sites More sharing options...
