With an integra Type R motor inside a 98 Civic coupe, which intake would I need to get/ As in one for a Civic si 1999 or an integra? I'm guessing the SI TB is the same size as a JDM Type R so I'm thinking a Civic Si will bold better for the chassis. (The one 10 mm bolt that bolts right next to the passenger shock tower). So experts help me with your much needed opinion.

 

if they itr engine has the same manifold design as the gsr engine then you need a gsr intake since the TB is on the bottom if youve seen how a gsr IM looks

 

gsr and itr have different manifolds. ITR intake is around 3" as the b16 is a tad smaller. for a short ram intake the ITR will fit and perform the best. Not sure if the ITR cold air intake fits.
