Default 3 port Vs. 5 port..powerband diff ???

Can someone give me some info on how the number of ports effects the power band of a motor. I am looking at the OS 12T 3 port and 5 port turbo engines and would like to know the diff. Also if anyone want to make a suggestion about what .12 or .15 engine to get. It doesn't have to be roar leagal...and I am looking for a ton of rip and good top end as well. Thanks for any imput. Oh yeah it has to be rear exhaust but could be SG or threaded.

The 5prt should make more rpm's and power up top. I'm not so sure but I think the 3prt should make a small probally unoticable amount of power. But I know for a fact that the 3pr has better fuel economy. The TR's adverage at least 9+ min on a full tank if tuned right.

FYI I've got a TR 5prt turbo for sale....
