65mm throttle body in a dc2r

[VTec1987]

Hey guys

I was just wondering, if i got a 65mm throttle body install in my car, will i lose power cos it's to big?

My oem one is goneskies, i just want a replacement. I know it won't gain any power. I rather it remain the same then lose power.

It should be fine to run a bigger TB ensuring that you have your IM bore out to suit the bigger TB

So will i lose power if i don't bore the IM?

ITR manifold has a port 64.5mm. So adding a 65mm will be ok. If adding a 68mm then you should port match to 68mm on the IM.

Cant port match 68mm to oem itr manifold will break through IAC passage
