I know this is dumb but I want to get the correct belts etc . Well I picked up a pulley kit from unorthodox racing and they are underdrive and according to their website I have run smaller belts. So on their install guide they give out the sizes of each belt (ac, crank, power steering, and alt) Do I just go into an auto parts and just give them these sizes or do I ask for the a specific belt in that size? Also as listed below on the ac which one is it that I get?

My car is a 00 civic si but it swapped to a poorman type r and yes I do have working ac if that matters. Same question with the power steering?

Here are the sizes I got from unorthodox racing:

Alt: (29 1/8” or 740MM).

A/C: 1994-01 GSR - Gates K040330 (33 5/8” or 955MM) - 1994-01 GS & Type R - Gates K040310 (31 5/8” or 805MM).
1999-00 Civic Si & 94-97 Del Sol DOHC - Gates K040320 (32.75” or 830MM).

Power steering: • P/S Belt: 1994-01 Integra, 99-00 Si, 94-97 Del Sol DOHC - Gates K040350 (35 5/8” or 905MM).
1998 & 2000-01 Integra Type R - Gates K040355 (36 1/8” or 920MM).

 

Yep, just give them the sizes and they'll hook you up
