Looks cool, if you don't mind me asking what does Buschur charge for that? So I can compare to proflow, and also what kind of gains are you looking at with it?

This is just a basic port job on the intake manifold, porting the runners and boring out the inlet to 65mm was $75. The TB conversion/boring was $300, I could have had it done for $300, but I would not have done this if I had not seen Dave Buschur post the solid whp gains from this little project, so I commited myself to give my money to him, instead of the other guys undercutting him and posting zero proven power gain results.
I am expecting a SOLID 15whp from the IM/TB combo, through the entire rev range. This will complete my porting project. With the exhaust mani (5-10whp), SS o2 housing (10-15whp), and this, I am hoping for a full gain of 30-45whp. My car made 295whp on just pump gas, so I'd expect ~330whp. I also bolted on the Evo IX turbo though as well, which is rumored to be upwards of +20whp, so I have set a semi-realistic goal of 335whp on straight pump gas, and have lofty dreams of 375whp with alky. We will see when I re-tune this thing.
