*EDIT* It seems all my pictures hosted on WVM were deleted for some reason so I have none to show you for the next few pictures. I will start uploading all my pictures to a different server to ensure I don't lose them again. Pics start below with the clutch install.*/EDIT*
This thread will probably become overloaded with pictures and words over the next month or so. Bear in mind if you don't have cable net or at least dial up, you're probably best off to just look at it from someone's computer who does lol. I'll start with a few details about the more complicated stuff I need to do and fill in the little things as I go.
In short I have finally settled on a turbo, fuel pump, piping route, tuning software, and horsepower goals. I also need to convert my returnless fuel system to a return style. I decided to go with a Borg Warner Airwerks S200 mainly because of it's twin scroll design which gives me several advantages over just a standard ball bearing turbo. First off the twin scroll design allows for me to split the exhaust pulses and decrease spool time by a huge margin over a standard turbo. The decrease in exhaust pressure also helps in using a smaller wastegate spring to keep the wastegates closed, which is helpful for the MSD LBC solenoids to modulate boost pressure on the launch. Also it means I don't have to run CO2 to keep them closed and modulate with the solenoids. The downside to this means I have to build my own manifold, which is not a problem really since I can use pretty standard steel to do it with as the twin scroll design will also lower EGTs. Having full race make me a custom manifold I found out runs an easy $2,500 and at least a month. Here are some crude pictures of the routing for header to the turbo:
Above I have circled the brake/clutch fluid resovoir (yes they share the same one), the fuse/relay box and PCM, the brake module, and the coolant overflow tank. The coolant overflow tank will end up on the other side of the engine here:
The fluid resovoir will be relocated all the way against the driver's side strut tower. The fusebox is going to go where the coolant overflow was. The PCM will be relocated to behind where the fusebox is sitting right now, all the way against the firewall. The brake module will then be moved over about 6 inches to your visual left, then down about a foot and mounted to the front driver's side frame rail, similar to where the air filter sits now. After having moved all that there is TONS of room between the transmission and the hood and the driver's strut tower and the head. But why you ask? To make room for the turbo....
Like I said it's a pretty crude drawing right now, but you get the idea. Basically the manifold runners will curve out from the engine in clean sweeps and head up over the valve cover (there's plenty of room) then a somewhat steep down then up curve into the bottom of the turbine housing with the two wastegates mounted right there below the turbine inlet housing. The turbine housing will exit with 3" piping down below back towards where the factory 2.75" downpipe is running now. The turbo's intake piping will run down back behind the transmission and towards the ground. The charge piping will run pretty much straight out from the front of the turbo's outlet facing the front of the car and down through the fender well to the inlet of the intercooler. Then from out of the intercooler it will pass into the passenger fenderwell, around behind the radiator, and curve up into the throttle body/custom sheet metal intake manifold. There is so much room between the block and radiator because GM had to make room for the blower and the huge ass intake manifold that has the intercooler for the heat exchanger built into it. It's a big boy.
Just to give you somewhat of an idead as to how much room the fusebox/PCM actually takes up, not including the brackets and such that space it about 6" up from the transmission.
Modifying a return style fuel rail from an older ECOtec engine. The inlet needs to be cut, drilled, and tapped for a huge ass -8AN fitting. Don't worry, that whole fuel rail isn't that small the whole way through. The over all inner diameter is about as big around as the pressed in plug in the end of the rail. Can you see the two different colored metals? The darker looking one will be drilled out completely.
Pre-turbo clutch install. Instigated by the 7/19 Mo-town meet haha:
Abused stock flywheel, resurfaced stock flywheel. Any questions? I am sticking with the stock flywheel because driving on the hills or Morgantown sucks with a lightweight flywheel and lots of torque lol.

The SPEC Stage 4 clutch. Sooo beautiful, soooo light. The only one that will hold more than 400ft.lbs. for my car, and I was making 350ft.lbs. on the stock clutch before the turbo even went on. Yikes!

For s-n-g's here is the car's subframe in the front. This whole thing only weighs about 120lbs.

And good old GM forgot to put a bolt in that holds my bellhousing to my engine. AWESOME! In their defense, this is literally among the FIRST batch of redlines (One of only about 80 made in the first 3 months of production) released, so some flaws are understandable but a missing bolt? Come on.

The correct .83 divided housing finally showed up for the S258 last week. Now I have a turbo I can actually spool well instead of the 1.15 they sent me. By the way, know anyone that needs a 1.15 housing for their S258/256? Lol.
