i don't think you've missed anything major, sounds pretty awesome
you sure you don't want to go front mount for all the work you're putting into it?

cutsom rear mount turbo
Another rear mount turbo thread..... it was coming anyway 
lol
well i thought id get some extra thoughts on this forum since the other forums tend to get stale from time to time.
current setup
98 trans am
stock 5.7L 346ci
stock cam
LS6 intake

OBX LT headers
catted ypipe
stock A4 with 3200 stall
stock 10bolt 2.73 gears
racetronix fuel pump and hotwire
301RWHP 314RWTQ 13.9 1/[email protected] mph spinning damn near the whole way on 315 sumitomos lol gonna get my kumho XS tires on and air them up for the track and not the highway and then make some passes. also gotta figure out how to launch my car withot spinning so much
HP goals for turbo build is 550ish and no more then 10psi. 14 psi will be availible but ill stick to just the 10psi spring until i get the tune right.
now for the turbo build items, ive got pretty much everything except the cam kit, base tune, and hp tuners in my garage. I can at least get it on and set up to run before i do the cam and meth kit.

well i layed everything out just to see how it would kinda route until i can do it on the car. we have been experienceing some bad sandstorms in el paso so im holding off on this, that and getting the rest of my taxes so i have the extra funds for those unexpected items

mocked it up and then high temp painted the inlet pipe
mocked it up and then high temp painted the inlet pipe
so i have a few more things to report, ill take some pictures when its light out again lol
installed the boost gauge, fuel pressure gauge, wideband gauge, and vacuum manifold log. also fixed the wiring so that my trans temp gauge actually dims when i turn the head lights on.
was really simple actually once i mounted the gauges in the gauge pillar pod and simplified the wiring. i pre fabed it so that it goes in as a unit. all the red 12volt switch wires bundled together, all the ground wires bunded together, and all the headlight switch wires bunded. the only one thats gonna be a hassle later is the wideband, but i am glad i set it on the botton pod position. the data serial cable, 2 analog sources, and wideaband cable sit just under above the vent lol but it shuold be ok. im not using most of them yet except the wideband.
all i gotta do now is hook a wastegate and BOV to the manifold. i also hooked up the boost reference hose to the FPR. its not getting pressure yet lol but its all hooked up so when i get the turbo on, it will be there when i need it.
the boost gauge is only getting vacuum right now lol but its reading -11 at idle. im assuming thats normalish. it moves been i apply the throttle. not sure what, it moved too fast lol its digital so its quick.
the fuel pressure guage reads 0 for now lol no fuel going through the FPR yet lol but its registered at zero so thats cool lol. i need to hook that up so i can check the fuel pressure.
tomorrow ill hook up the wideband sensor so i can check and see what my AFR is.
the vacuum manifold kit was great! had all the fittings, different diameter hoses and barbs to do everything! got it right off the booster. for now the two other ports are blocked off until i hook up the wastegate and BOV. the meth kit will have to t off something. the BOV hose should be ok for that since it will be the closest to tie into for that.

i think tomorrow while im under the car ill also start putting the oil pump in there. just to get it ready to hook it up. the less i have to do the better when the turbos ready to go on it.
heres the pictures i promised

and the first test fit is a success! got the pieces all welded into place and ready for final installation

now to run some oil lines, mount the pump, connect the fuel return system, and run the intercooler and charge piping and we are in business
