I'm thinking about getting a Holley TBI for it but I'm not sure. The claim is 25 HP increase, I find this pretty tough to believe. Has anyone on here done this? If so did you notice a sizable increase in power? What are other things people on here have done to up the power out of that little v6?

Chris,

Copter Steve again, the 2.8 in your trooper is a gm motor, same one they used in S-10 pick-ups and blazers. I looked up the cam shaft on my Napa Prolink account and they are the same. I think a really good way to up your HP is to put in a aftermarket cam shaft. If you research it you can probably find a RV cam. Another option is to buy the stock cam and have a custom grind done to it. Back in my Hi School days we hopped up a lot of 4 cyl nissan pick-ups this way. don't forget to put new lifters in with a new camshaft.
