hmmmm well i was gonna get the turbo ported anyway, and i was going to get a new manifold, what do i do to use an external wastgate? how do i use one

 

If your going to port a external WG is not necessary. I personaly think it is overkill, unless you have bigger plans in the future. Not to mention it is expensive.

 

I have a Big 60 trim T28 turbo And I love it. you don't have to mess with all the install kits and welding things together. The Big T28 just blots on like the T25 but you can def feel the diffrence. Right now I got mine running 16 spi and it holds all the way to red line. I get full boost at 3K rpm's. I would say get it.
Here is the map of my turbo. and if you dig back to like th 4th page under turbo's I have a post with people explaining this turbo to me.
