I have a JDM ITR Intake Camshaft and want to install it on my B17a1 VTEC motor. Will I notice any gains or do i need the exhuast camshaft as well? is it worth installing?? what about any tuning done? would that make any difference? the motor is stock with I/H/E.

 

Will work good on just intake.

Just limit rpm to 8200 on stock springs. Should upgrade springs as soon as you can though.

 

do i need to change the intake valve springs???

 

You should change all the springs but if you are stapped then just do the intakes springs first.
