Figured it's time for some up dates and bring new pictures to the thread.

Finished 2 IHI's, almost done with another one, and one's on the table about ready to go under the knife.

They're really turning out good!!!! :thumb:

It all depends on how much time you put into it and what you want out of it.
I spend ALOT of time on them; it seems like I'm doing more and more to them each time.

When I was running an IHI I ported/polished my intake horn and it made a big difference.

How does is drive? Did you notice much difference?

She drives amazing! It took me about a week from teardown to reinstalling everything, I work and go to school so I only had about an hour or so each night after school to work on it.. I know I could have spent more time porting/polishing, but what I did made a pretty noticable difference. The first day after I left school, I hammered it and everyone just stared at me! I had some guys ask for rides in my truck too :D the turbo lag is pretty close to gone, and the truck has a different rumble to it, im guessing thats from porting the exhaust? I also installed a billet wheel from wetzel performance, and ported the turbo horn

Sound's like you enjoyed it, which is the point as well.
The reduction in lag comes from opening the up pipe ports and opening up the in take horn; that's what I've noticed anyway. Obviously the billet wheel helps.

I also spend a lot of time on the ones I do, it tedious.

Just a quick question out of the batmo wheel or the weztel billet wheel which one has the most whistle on a non ported/polished turbo? Then on a ported/polished turbo just trying to figure out which way to go for the most whistle

I installed a Wetzel wheel during my port and polish job and the whistle was heard the greatest at higher speeds. But since I got a 4 1/2' CAI, the whistle is pretty much 100% of the time, and its pretty loud..
