i'm thinking about doing a swap i want to use a gsr motor and i was wondering if there are any aftermarket intake manifold or do i have to use the stock one?

you should search for some www.jdmhondaparts.com and other sites, youd get a quicker answer

Skunk2 makes a single-runner inatke manifold...and you can also check out jg edelbrock, they also make an aftermarket Intake mainfold for a gs-r.

skunk2 goes for 250 and you can expect gains of 5-10hp...depending on your setup.

Good luck
