STS Concerns
What's so hard about installing STS over anything else? They advertise it can be done with little mechanical experience over a weekend in your garage.
Surely a master mechanic with years and years of building FI and racing experience should be able to handle a simple bolt in kit that the average Joe could install in his garage?
Of course you want to think whatever you have is the king ****. That's why you got it.

I think one reason many choose a rear mount setup is that you have much more space to work with and don't have to move accessories like alternators & radiators around, and changing plugs are not a pita x 10. so the major issues everyone always talks about with a RM is oiling for the turbo, ground clearance, and exhaust heat. exhaust heat - no problem, coat & wrap the hell out of it. ground clearance - can't be much worse than a lowered car with long tube headers. so really my only concern with a RM setup would be the oil supply, and if you spend enough time & money with it-it can be done right and work properly. just my 2 cents.
Not saying STS is a terrific setup to go with; I'm just in the middle of making a chosen FI direction... D1SC, custom front mount retaining a/c, or a custom RM
I'm not bashing a working rear-mount, just STS. Although I think it's a bit odd and my personal preference is supercharging.
Sometimes spending shitload of money to get a KIT to work right isn't everyone's ideal choice is all I'm saying.
My kit works great....after it was made to work.

For my setup I have blocker coated manifolds, stock cats with all exhaust pipe heat wrapped to the turbo. I used welded flanges and gaskets to connect the exhaust system to the turbo rather than slip joints to avoid leaks. The only mod I made to the STS system was to the crank case ventilation system. The crank case pressure was building up during high boost so I had to go to a vented catch can. The garret turbo that came with the kit failed shortly after being run on the dyno. Journal bearing went out. They swapped it out and upgraded me to a dual ball bearing at no cost for the trouble. I have had the kit on the car for about 3500 miles and it has given me no trouble after the turbo was replaced. I need to get the car retuned now since the new turbo is flowing way more air. I can only run 9.5lbs of boost before it starts going lean. I made just over 500 rwhp on a mustang dyno at 9lbs of boost with the bad turbo. I am building full boost around 3000 RPM in third gear. My stall is so much higher than that I do not have any lag.
So as far as concerns for the STS kit:
1. Constantly having to kill myths and prove to people that a rear mount it a great alternative to a FM or a charger.
2. PCV\Crank case ventilation system not good enough for 15lbs of boost
3. Exhaust leaks can be big performance killers.
4. Keeping exhaust gas as hot as possible.
I hope some of this helps the OP as well as others that want to hear some facts from an actual owner of the kit.

i have never seen an FM guy go to a RM set up, but i certainly seen plenty of RM guys going FM
watch those cats, from time to time they like to spit stuff out and the exhaust wheel on the turbo does not like it much
name me a myth that you killed in this thread, but yea RM is not a bad alternative

Oh, and the GTO got the slave and a new Spec clutch and is currently sitting in a field.

Before everyone throws the BS flag on me... I spoke to one of the head guys at STS when I was first going down the road of building my car... and that is almost verbatem what he told me. I think it was something more like "our kits are for the budget minded folks that want good performance... not race car performance" and when I pushed them to help me in my build by providing some piping (I was doing the rest) he said "we are not really interested in doing something different, we have a good model and it makes us money".
So... I own the fastest rear-mount F-body in the nation (still think I hold that crown)... and the other F-body's that are close (Zombie and 1320) would echo my feelings that our kits are NOT STS kits... my kit has nothing in common with them other then being rear-mounted... and if that is the same, its kinda like calling a Chevy a Ford... because they are both cars!
Now all that being said....
I dont mind STS and think that they produce a great "budget mild performance" turbo kit. If you want real performance (700+RWHP) I suggest you go another route... or custom.As for us... we will see 8's this year... oh and the car has an O/D trans back in it... so its completely street mannered and appearing... (Other than that big *** turbo tucked in the back)
I got my 42LB injectors in the mail last week, and order heat wrap from Summit today which should be in by tomorrow or Friday. On Friday or early Saturday morning, we will be starting the install. How much heat wrap do I need really... what should I wrap... everything almost? Also have to figure out how I am going to "do" my front end (appearance-wise) with the FMIC.
I have decided to go with Motor City Speed in Commerce Township to do the tuning after the install; Rich Gala over there does some great tuning and tuned someone's LT1 I know in the past and he did a great job with what the guy had done to the car.

Have you upgraded to a Walbro 255? If not you need to... another cheap mod for better performance is changing your heads to the LQ9 truck heads (You can buy for $300). They have much larger chambers and it drops your compression on your stock block some... better for knock and engine protection.
