Does the 1g IM need to be ported to accept a 63 mm TB?

Just curious...I ran a few searches and I couldn't find anything. If the stock IM is 60mm I certainly won't be wasting any time porting it.

Thanks

The stock size of my 1G IM is 60.64mm. you will have about 1.15mm of hangover of the IM to the TB. Not much to get picky about. Some people would be I wouldn't. You will be just fine running that TB on the stock IM. If you would prefer it to be completely flush with the flanges then just a few passes with a drymal and a barrel sander and your golden.
