I have a Ported TB and a stock plenum up for sale. I already sold the ported plenum. I gained 12hp and 19ftlbs with the ported TB and Plenum vs the stock TB and plenum.. When I ported the TB I went through on the backside of it. I fixed it and kept on going to work on it. I put it on and had no issues and gained good power. You can see where I patched it up on the backside of the TB. I would like to get $80 for the both of them shipped. Would be good if someone wanted to work on the Plenum to complete the combo.
