Default 6.0L turbo into a Buick GN

I suppose i can post this up now, i have lurked on here for years, but never had much to say. now i have something to show so its ok! Heres my build that ive been working on the last year.
87 Buick T-Type, WE-4
the v6 finally let go with just bolt ons, had a k&n, RJC power plate, 3" downpipe, TE-44 turbo, 3000 stall, 36# injectors, and a really bad meth habit. Best power i made was 410whp, 590wtq, and always on pump gas and meth, usually at 26psi. best i ran was a 12.12 at 113, on radial T/As. haha, 2.1 60' on that run. anyway:
pulled body, blasted, boxed and painted frame
blasted body, fixed floor and painted
ss brake lines, alum fuel lines, -8 feed, -6 return
Poly body bushings
all new suspension and steering components, UMI in back, poly graphite front
manual brakes and manual rack and pinion (this summer)
new fuel tank with my 1 previous walbro 340
02 LQ4 6.0L iron block
224/224/112, .560 lift lunati -6 camshaft
Typhoon intake
65# injectors
2 bar HP Tuners
cut 2.2" out of oil pan
completely re-did harness by myself
stock 4L80e and converter
Headers made by me, box of bends and flanges from schoenfeld
Borg Warner S400 turbo from Majestic Turbo in dallas
front mount, have a powerstroke, but think im going to use a e-bay one

so thats what i have so far. I am really big on doing my own stuff, and every single thing on here i did myself. also i just learned how to TIG this week, by welding my own headers, so they dont look that great but i'm proud of myself i guess. Well, heres a bunch of pictures, just got a new laptop and this is all i have at the moment. please leave comments, but keep it on topic of this car only. no post whoring. thanks
Gary

Looking good....

I do think the driveshaft in pic 06228S will need a wee bit more work

Good luck getting it knocked out.

Looks good! I've been following the build at TB.com. I've been helping a friend with a similar swap. We did an aluminum 5.7 block with Escalade heads, a TH400 and a carb style intake in his GN.

Lookin good! Tig welding takes time to master, take your time and clean the metal very good. Good Luck.

well im keeping it divided, and the pass side is just gonna curve right into the turbo, drivers side will curve down and go in front of the crank and into the other side. I am using the truck water pump, and only an alternator. you can see that i took the stock truck acc. bracket and milled off the power steering mount. Plans are to go to a manual rack and pinion in the future. Also this thing fits in there so good, i didnt touch my trans tunnel at all, what helped the most is the new body bushings, it raised the body up 1/8th inch.
I got my headers welded up, finally. that took forever and a day, and no they arent the sexiest things around, but it will get the job done. i finally got pissed and grabbed the MIG gun and finished em up. also made a plate for the heater box, out of 1/4" alum diamond plate. haha, it was layin there and i figured what the hell, i can always change it. So now it goes back to the small shop to sit for a week wheni go play on spring break. hopefully i have some extra cash when i get back to order the rest of my plumbing so i can run it. then its just a driveshaft, master cylinder and brake hoses and its driveable! has to be driveable by may 1st for a local car show, we'll just see about that.
