yes its possible. i have done this on my 165, i dont know of any benefits other than a little better spool that is hardly noticable, but the twin entry manifold/wastegate port isnt prone to cracking like the single entry.

check these 2 threads for info

i was reading some benefits of twin entry, i dont remember from what post/thread/website, though....but with twin entry, isn't it true that the manifold runners have better flow, due to less/no cylinder cycle clash? i thought it has better airflow...but then again, i suppose it would only result in a slightly better spool? :shrug:

No, you're right. Because of the certain firing order, the twin entry doesn't cause as much "exhaust flow clashing" and here's something i actually just read last night to help explain a little. There's actually no drawbacks to switching over to twin entry.
