I'm looking to port match my stock rsx-s TB to my skunk2 intake manifold(Rbc) with a 70mm tb opening. Is it worth doing all the trouble to port match it? or should I just buy a 70mm throttle body? I've used skunk2 TB on my DA integra before and they suck, that's why i'd like to see if anyone here has ported their stock tb. If this gives me more than +5 or more hp and smoothens the powerband, I'll do it.

Stock TB worth portmatching to skunk2 intake manifold with 70mm opening?
The biggest you can bore an OEM typeS/R TB to is 65mm at the butterfly plate (bore). They can be tapered to 70mm at the entry max.
Maxbore bores the OEM TB for $150. Unlike Spoon or J's Racing charge out the ass. Kingmotorsports also does the OEM TB (upon request). If you are after a 70mm TB, I have a brand new K-tuned ($200) TB for sale.
I feel I do not need any larger than 65mm using (11.0 compression) and Drag Cartel DIC's with an RRC IM. Right now I am searching for machine shops that can swap the internals of an OEM TB over to an aftermarket unit. I haven't heard of anyone going after this type of custom work online.
