Re: porting HF manifold
 

:-p... I guess I'll check out a few more tool stores and try to find some appropriate bits.

So how deep down into the manifold do you think I'll be able to get to. I'd like to open the runners up from beginning to end.. but is that even possible? I already have my 14B exhaust housing opened up and por matched to my adapterplate. Just looking to get a bit more out of the mAd JDM manifold O0

You won't be able to get inside the whole port, you don't need to. Just port the side of it that connects to the head and you're good to go.

Summit Racing has the bits. The bits are over 6 inchs long. Bits have 1/4 shank on them. http://store.summitracing.com/defaul...s=P%5FRank%7C0 I saw some bits on tptool.com also.
