hey guys, i was lookin into gettin either a 55mm or 60mm throttle body and sendin my mani to fierro to get it port matched or whatever...but my question is, which size throttle body would be better?..im gonna be stayin NT, and i heard 55 was better for a NT but then everybody says to get a 60mm with a ported mani...by the time i get all that done my mods will be, exhaust, intake, UDP, OBX high flow cat, and possibly obx headers..i dunno bout them yet...thanks for anybody that helps

IMO get the 60mm, most will tell you its too large but hey...most have been really happy with the response/power from the 60mm

Mods are:
Not enough

i was thinkin about the 60..but i also heard that it hurts your bottom end torque..which i need for where i live lol..gotta drive through the mountains everyday to get to school


Mods: E-bay Intake, Vibrant Exhaust (lol), J Woodleys Ground Wire Kit

Waiting To Be Installed: Obx High Flow Cat

I would also say 60, but I still havn't recieved mine yet... should havee been a few days ago... hopefuly all will be good with it...

sidetrack question... how wide is the bore on the intake mani from the factory?

I have to add my $.02 here...

I have had the 60mm TB on for a while now...I had to switch back to stock for a while. And let me tell you now that I went back to stock, I KNOW I lOST low end tourque with the 60mm.

The stocker has more low end torque, so I'm figuring the 55mm will be great. That is my next thing to do 55mm TB..

DOn't get me wrong I love my 60mm but the 55 is gonna be better.

after reading the above post by AFX and speaking with Michael97RS I have figured out a way how to keep my power using the 60mm TB that I ordered and am still waiting on...


Before installing remove the mani (duh) and bore the intake mani to 55mm and put a taper on it (only 5mm so 2.5mm on each side= not much) going from 60 to 55 as smoothly and with as much of the 55mm bore as I can (keeping as much 55). walah, I have a 55mm bore with the option of opening it up in the future for my crazy boosting ideas.
