It's begun. Turbo Build.
Got my flexplate in the mail, I'm going to stick my th350 behind it and see how long it lasts. No reason to convert to the th400 then go to the 4l80 once it's built. So right now I need to get some motor mounts rigged up, wiring done, and get it running N/A. Then focus on the turbo part.
Update
Got a 8.5 inch 10 bolt for the car. Has an auburn LSD in it, this will make it easier to find gears/ be streetable.
Oh, it fits in a grand prix.

On to the turbo. Finally got one, so here is a size comparison.
Garrett t25, and a ravioli can.

Same can, a t25, and my holset hx55

The turbo from one end to the other is literally as big as a 3800. l36 intake for reference.


Other then that, not much new.

Bump, it's N/A now, going to get my nitrous kit hooked up and a manual valve body in here soon.
What was done to it so far.
5.3, 100k mile motor. Just did gaskets on it, etc. Removed all of the torue management so far.
Th400, mostly stock rebuild. Dyno'd and should be good to 800hp
Solid home made motor mounts
Rear upper and Lower fully adjustable control arms
Chromoly Iceman trans crossmember
Brock fab radiator support
Lots of engine bay cutting and removing of stuff I don't need
Rear sump summit 16 gallon fuel cell
Bosch 044 In line fuel pump
Corvette fuel regulator
All stainless braided line and AN fittings
Returnless fuel system
LT1 Camaro Radiator
Some stainless radiator overflow
F-body hooker headers cut and beat up to fit
New rear end bearings, still needs some new end axle seals though I found
All new front calipers and pads
New brake lines from the proportioning valve back, with new wheel cylinders in back/all new hardware
Had to modify a 4l80e trans yoke to fit
New driveshaft U joints
New gauges and dash panel
Made a PCM tray/heater delete panel

Been beating on the car recently. Got pulled on hard by a 383/Nitrous lt1 camaro, but hey, it runs, right?

looks good brock. so why you decide to spray instead of going turbo? saw your collection of turbos few pages back lol.. mine finally and slowly putting back together too now that i have fund. trying to decide if i should run speed in TU2 cam custom cam grind. i might have to bump up to 85 lbs injector. gonna run the 65 lbs first and see how that go.

We're doing something similar in a G body here. 6.0 LQ9 with a TH400 or 4L80E
I'd highly suggest pulling the pan off. Seeing the rust in the cylinder there's probably rust on the pickup tube and crank.
I'd also highly suggest picking up a set of Katech rod bolts. They don't require resizing the rod and are just cheap insurance. The weakest point is the rod bolts then the piston then the rod.
