I guess If I want 3800pro to make a comeback, I'll have to make some posts. Besides, it's hard to get help when nobody knows about your car! I've been building mine for a few years now with a lot of trial and error, so it might take a while to list everything I have going on. Here goes nothing.

I bought this car of my buddy's dad in early 2018. He bought it brand new, and I remember thinking in 3rd grade that it was so rolling around in a brand new black Camaro with a stick. lol Memories like that are always a motivator to keep working on it.

It was far from cool by the time I got my hands on it though. If it wasn't a factory black with stick shift and 0 options car, I probably would have passed. What I really wanted was a Grand National roller to swap a 3800 and a stick into and make it turn corners. A horribly rusty 4th gen with a lot of sentimental value and the V6/stick already in it was the best I could do. I don't regret it. It's a cheaper chassis to modify, and it's nice to mix things up a bit. The whole reason for wanting another project in the first place was that I already had a nice stockish GN that I was too scared to drive regularly. Door dings, racking up miles, and breaking parts while racing was not something I wanted to do to a car that was getting so expensive. I actually don't even particularly like F-bodies so blowing one up or getting a scratch will not hurt my feelings one bit. This is my alternate commuter car.

Anyway, here's what I've done.
-Ebay 6765 turbo. It's a bit large, and the lag shows it.
-Stock driver side manifold, modified crossover, modified front log from a FWD, and custom merge.
-Ebay front mount intercooler mounted to a Midwest Chassis bumper support.
-Precision PW40 wastegate and Turbonetics MBC
-LS6 valve springs with modified retainers
-AEM 50-1200 fuel pump, custom hotwire, and hinged trap door
-Siemens Deka 80# injectors
-Custom upright radiator supports
-Custom PVC coolant recovery bottle 馃槄
-DIY battery relocation with BMR tray
-Modified Hawks Sinister 4" single shot exhaust with Magnaflow muffler
-Custom serpentine belt routing (deleted AC with no goofy belt sizes or extra pullies)
-Custom AC delete firewall plate, heater fittings, and HVAC box (heat still works)
-Evap. and EGR deleted (not recommended but I wanted the space they took up)
-Threaded IAT where the EGR used to exit
-PCV passages blocked
-Moroso catch can and -12AN bung on valve cover
-Crank drilled for Nissan SR20 flywheel bolts. (I got tired of buying TTY flywheel bolts)
-Spec "Stage 4" solid hubbed 6-puck clutch
-Tremec TKX
-3rd gen V6 F-body bellhousing
-Tilton adjustable HTOB
-Tilton/Tick adjustable clutch master cylinder
-Custom shifter
-Locally made 3" steel driveshaft with 1350 ears
-UMI panhard and torque arms
-BMR strut tower bar
-ST front sway bar
-ABS delete with line lock
-Stock 3.23:1 open rear end
-Ortiz custom gauge pod with scan gauge, AEM wideband, and AEM Tru Boost
-Tuned by Dyno Brian at Dyno Tune Motorsports. (y)

The car made 330hp and 400ft/lbs with 10psi. I was ready for much more, but the stock valve springs were not. Once I get all the bugs sorted out of this thing, I plan to install a bunch of parts I have in my basement.
-ST5 cam
-L67 head gaskets
-ZZP head studs
-ZZP lifters
-PAC 150# springs
-Double roller timing set
-Machined oil pump cover
-Spohn tubular k-member
-N2MB wot box

For now, the car is a riot to drive. I've learned a ton with this thing, and look forward to showing off at a few events this year.

I remember you posting this a little while back. Very cool build and different from the typical f-body ls builds you typically see
Thanks! Yeah, I think I posted an introduction a while back now that I think about it. My bad. I just hope keeping an updated log in here will get more people telling me how I can make it better. lol I don't know everything!

I'd love to go, but I have a wedding in Milwaukee that weekend. It's always something. If ZZP does another 3800 dyno day soon I'd be all over that!

I've made some changes since the last post. I tried realigning the bellhousing for smoother shifts. I didn't really get it though. I'm convinced that concentric within .005" on a stock aluminum bellhousing is unobtainable. There's too much slop in other parts and the bell itself is probably getting twisted a bit with the torque. It was originally made for a gutless 2.8L afterall. I would feel a lot safer with a steel bell, but I don't have the money to have a custom one made for me. I'm going to drop this until I start making real power.

While I was in there, I tried fixing some stuff that was bothering me. The TKX didn't fit my original floor hole or boot, so I was scumming it with this... thing.

I tried covering it with a Freightliner boot which would have been perfect if I didn't have a bunch of wire harnesses nearby or a console.

So I had to make my own. I like using CAD when possible.

Don't worry, I bought my wife a prettier welcome mat before removing this one from the kitchen.

Now I'm scumming it with welcome mat technology. 馃槀 It works surprisingly well. The cabin is quieter, the hole is covered and the shifter still moves fine.

Before putting the console back in, I had to repair the seam that popped loose. I have a soldering iron that I use for plastic welding and a bag full of cut hog rings that I embed for added strength. "This ain't goin' nowhere."

And once it's installed you can't see the blob. lol

I tried ordering a console lid to arrive before the GS Nationals, but no dice. It's going to arrive about when I get home. It's going to be a long drive there and back with my arm resting on the corner by the cup holder. lol At least it shifts a lot nicer! Even though the bell is out of whack, I found that I can only open my speed bleeder about a 1/4 turn without sucking in air. Pumping too fast also brings in air. Needless to say, the pedal feels great now that I know how to bleed it.

Per the advice of some smarter folks, I dropped the snorkel. I kinda liked the look because it sorta matches the GN. However, I realized that it was an awful inlet restriction. Now that it's gone, the boost comes on a lot quicker, and the sound is amazing! I think the turbo location looks a bit silly now, but I'll live with it for as long as this turbo survives.

Now that the car feels mechanically ready to go, I just need to spruce it up and pack my things! I've never spent as much time of the paint as I did yesterday. It turns out that you CAN polish a turd.
