OKay well heres the deal. I was going to place an order today for the afx udp and the 55mm tb. When I called howell the guy said he knew for sure he had the pulley but wasnt sure if he had the tb and he wouldn't go and check for me. I dont feel like waiting weeks and weeks for it so I was wondering if I should go with the 60mm from modern performance. I did a search and found that the 55mm seems to be the best size for n/a because the 60mm slows down air velocity but since my intake manifold isnt currently port matched will this still be the case. Just wondering what you guys think. Should I wait and get the 55mm or go ahead with the 60mm right now. Any help is appreciated and thanks in advance..

but if you arent going turbo 55mm is the best way to go. 60mm will inhibit the air flow, its just too big of an opening and you dont have the means to push all that air being n/a. Wait a few weeks for the 55mm or find one for sale on here, dsmtrader, or the partstrader.com. Why buy a mod thats going to hurt performance?
