As stated by Bansil... http://www.alamomotorsports.com/alpine/alpine_isuzu.html
add a free flowing exhaust and a K&N air filter and you should see a 35-40% increase in HP.

I know Jerry Lemond just got one for his 3.5L, (not sure if it's an Alpine or if he's installed it yet). I'm sure he could tell you all the tricks.
