I could, but I don't plan on keeping this turbo on the car for the long haul, sometime next year I'm going to completely redo the turbo setup and put a much better ball bearing unit in.

Sounds great, be cool in residential areas and don't be too enthusiastic when rowing through the gears in the neighborhood because that exhaust is going to echo louder inside homes than it will inside the car and you may find a cop hiding in the area looking for you after enough complaints role in. There's (was) an obnoxiously loud Honda that passes by my neighborhood like clock work probably going back and forth to work which i'm sure has made a lot of people angry. Not long after, I noticed a cop car parked behind a building about 50 yards from the parking lot he turns out of onto the main street to start his routine.
It's fixed now. It wasn't so much his speed that I observed as it was the ridiculously loud exhaust which he probably had no idea was excruciatingly loud to those in the homes he passed. Four cylinder motors with little to no exhaust sound horrible and I suspect the cops caught up to him and pointed that out probably resulting in a proper muffler (sounded like about 5 ft of pipe and no muffler with the end dragging the ground). Just a warning because I found myself in a similar situation years back early in the morning and had no idea how effectively the exhaust echoed off high surroundings despite being a good distance from surrounding homes. I crested a hill early one morning and saw a cruiser in the median pointed rt at me and got the message to keep the exhaust cutout closed or the rpms down.

started the mounts for the LS2 coils, they need slight reinforcement, but shoult work ok until I find a better way to mount them. I'm thinking about modifying a set of valve covers to mount them similar to how they are done on a stock LS1/2, but this should get the car running for now.

Why did you decide to go with LS1 coils as opposed to the less complicated stock coils? I know that sounds a bit hypocritical given the number of times I've taken the proverbial back door to get to the front yard but now I know less is better.

Following. I like you persistence, many would have just called it quits after a few failed attempts. Once all the little bugs are worked out it should perform well.

I'm anticipating a new non Fiero project in the near future and thought I'd pass an idea I have on to you. I found it difficult to install an exhaust system that was both free flowing and quiet due to space constraints. I settled on an electric exhaust cut out which worked well. The car was quiet enough with the cutout closed for neighborhoods and open enough with the cutout open to prevent restricting the turbo.
I read where you intended to dump the waste gate exhaust down stream back into the down pipe ahead of the muffler. You can do an open dump with the waste gate without it making a lot of fuss by adding a foot or so of pipe onto it. I used a stretch of flexible exhaust from Advance which worked very nice. I would hear a brief "whoop" sound like blowing over the opening of a jug inside the car when it opened which was rather harmonious instead of sounding like a high pressure exhaust leak.
As for insuring good exhaust flow, instead of another electric exhaust cutout, I'm going to use an appropriate sized external waste gate with a manual adjuster, mounted ahead of the muffler, adjusted to open at the desired boost pressure to open dump or, bypass the muffler and dump inside the exhaust down stream of the muffler. It's more efficient than an electric cutout in that it will open and close automatically. Just something to consider.
