Yes sir, I think Ive decided to mount the exhaust housing in the fenderwell. im planning on running some 1 5/8 tubing through the framerail for the drain. The compressor side should barely be past the framerail.

Not much of an update, but I'm hoping to get started on it soon.

Nice work and car. Kinda sad you're going turbo. It's what everybody does these days I guess. Love the view at the new house, congrats!

Yeah, it's just so expensive to get anything to handle that much nitrous. Thanks, we love it!

Well I ended up with a forged 383 ls1 with a super Vic, cnc 317s, and a glide. Guess I'm going to throw together a little nitrous setup while I gather parts for the turbo build. I can't wait to get this going again!

Very nice build , mine will have a 370 on nitrous when I finally get the swap done. I'm thinking about deleting my rear spoiler.

Thanks guys, I actually traded the OBS for a Duramax and a notch back. I've been wanting to swap to a cobra spoiler, but no spoiler looks decent.

Got the car back to a roller and got the engine together for the most part.

I seen that on the 4150 tb setup you used a Ford TPS. How did this work for you? Its a 5v 3 wire sensor, correct? Was the stock LS pcm able to read and control using it, and do you have the pinout for that sensor? Sorry for firing off so many questions, but I have a very similar setup going on a 70 Cutlass with that same TB and need a few pointers. Thanks in advance, and nice builds by the way!!!

Havnt updated this build in a while, everything else seems to be getting in the way. Just finished up a turbo build on an fbody so now I finally have had some time to work on it. Pulled the trans back out and swapped cases. The first one was cracked in the rear clutch pack area. Went ahead and did some fender exits as well. I'm hoping to make some motor passes on the 29th.

Well I finally got it on the dyno and only got to make a couple of pulls before we noticed the oil pressure was too low, so it looks like the engine is coming back out. It made 404hp and 488 ft lbs through stock exhaust manifolds! I did go ahead and make a couple of track passes on motor. It went 7.4 @96 with a 1.77 60 foot. Plenty of room for improvement. While I have the engine tore down I decided to go ahead and do the turbo setup.

Been a while since I updated this, got the turbo setup on and running. Also added to the cage.
