what throttle body should i combine to the itr/ctr intake manifold for best results? it is going on an n/a motor (b16a1), would it be better if I got the intake manifold ported and polished combined with 68mm- 72mm tb, or just stick with stock manifold with stock itr tb? how much of a difference between the two? Thanx for any help you guys couild give, i just want to go the right way all the way throw this time.

 

Use a stock ITR throttle body.

 

acura TL throttle body

 

STR 68 or 70 mm

 

70MM spoon... and no.. im not a sell out.. but its the ****!
