I'm getting the zex n20 system, would it be beneficial to also put in the type r cams?

 

Your car will scream with that setup. I know someone that has a ITR intake cam and 100 shot of nitrous in the 12's.

 

what about the type r ecu?

 

They work well together. You can see my car at AbsoluteVtecTuning . I've got CTR cams and a 55 shot (I like to keep it low). I ran 14.32@98.5 on streets (2.35 60') in 100 degree weather. I think You'll like it. -C

 

you don't need a ecu, just get a Apexi Vtec contoller, that is only if you are trying to change your VTEC x-over point, even if you are trying to add more fuel. I would say get the VTEC controller if you want to change your VTEC x-changeover point or fuel adding or subtracting. If your trying to change your Redline then you'll need a new ECU. Otherwise it's not worth the money.
