Going together hopefully for startup (soon). As I work on it I realize all kinds of little parts I dont have and more broken things.

Killmat is done, Allstar trap door is done (10x14), carpet and seatbelts look mint, fuel pump, regulator, and PTFE lines are done. I need pedals (3), console trim, make a crossmember, sell the 60e and converter, hack a big *** hole in the floor etc etc. Not sure what to do with the new trans cooler I just installed. One step forward, three back.

Against my will Ive become very good at GM Saginaw type steering columns. This one was sloppy, but in overall very good shape, it needed spacers to tension the bearings, an ignition retaining pin (missing) and I installed a new GM ignition.

Here's one of the main delays on this car. I drug this home (on a trailer). It was $1500. A cheap, older, non-running at the time BMW......yeah. It's running now and Im dailying it for the time being. Now, on to more progress on the white Z.

The car was close, or so I thought. I was planning on grabbing a license plate and taking its maiden voyage. I went to pull it in the garage to do a front end alignment and it would barely run. But lets recap how we got here. The car was a stockish 5.3, a 98 fbody pcm and harness. This car was tuned by me and has always ran really well. When I turbo'd it, the changes (that would effect it running) were: 80lb Dekas, 3 bar ZR1 map, and a 2bar OS swap. The car has been running very very rich since the get-go. I have one of those junky chinese FPR on the car and it was giving me like 100psi of fuel pressure. Makes sense it would be rich right? Got that all sorted and it was still rich but I figured the tune was off. So when the car wouldn't run anymore I grabbed hptuners and took some fuel out of the VE. Still rich, repeat, repeat, repeat. It just would not act right no matter what I did. I also noticed the TPS 5v reference only had a 2v output which was weird, that was never an issue before, and the car ran fine a couple of weeks ago. Soooo, long story short I have an 01+ 0411 PCM I'm gonna repin the 98 harness and put in the car. It will not be going in the stock location, but moved to under the dash. So that's where I'm currently at, in the seventh circle of hell.

Soooo, long story short I have an 01+ 0411 PCM I'm gonna repin the 98 harness and put in the car. It will not be going in the stock location, but moved to under the dash. So that's where I'm currently at, in the seventh circle of hell.

Didnt wanna do it but I pulled the engine harness off the car. Two reasons, one so I can trim all the unused stuff out, and two so I can solder it on the table. This has been quite the learning experience AND a consumption of time.

This is the trash pile. Notice the 4l60e connector and all emissions and o2 sensors. Gone.

Why do "budget builds" turn into money/time pits?

Update......and I realize some people paying attention may think I'm the slowest car builder ever. But I will clarify some with this post.
We can start with the quick performance 9 inch as you've seen by the teaser pic. So I've been assembling rear ends for me and lots of other racers in the area.....so I've done a lot. Putting this together was aggravating to say the least, not only am I not super versed in a 9 inch (although I tell the ladies that I am) these gears just seem to be not that good. With an absolutely gorgeous coast pattern I get this junk **** for drive side. And I wasted way too much time fooling with it.

1 week later I do a GM 8.5 truck diff and its beautiful. These gears are however cheap so if they break or howl, they will just get replaced. The end product is aluminum through bolt case, 31 spline trutrack posi, QP diff at stock length and powder coated. The housing took 6 weeks-ish to get here.

I left you hanging with the harness situation. Long story short everything was installed and it still wouldn't run. All 5v sensors worked (tps, iat, ect etc.) but the 12v sensors were dead (cam/crank). I decided to buy an ebay complete harness and swap them out. That part literally wasted weeks, all the soldering etc. Not only that, after it didn't run with the new PCM and harness a friend suggest changing the plugs. Wow, it cranked, sometimes its the little stuff you overlook. All is well after some hptuners magic and she is running perfect on an 0411 pcm and 3bar map.
Safelite came out and installed a new windshield to the tune of $500 ouch, and of course i needed new wipers. Most cars are J hooks, super easy right? These goofy things are reverse J hooks and require a special wiper. I'm at the point where I think nothing can possibly go right on this build. I also bought new wiper arm covers (which covers the bolt end) and had to buy new pushpins for the cowl (which I didnt have enough of the right size).

The tach didnt work with the 0411 pcm and everything I read said that it was an unusable signal out for the old school tach. I tried everything after purchasing this and wasn't much was working but I figured it out, now listen close for you googlers who might find this in a few years. This coversion box works IF you grab a signal wire from a coil pack as input, set dip switches 1,2,7 to ON and off 3,4,5,6 to OFF and use the 5v signal out for the tach. Works mint.

Sidenote pic, I'm a welder, have been a long time (not my primary profession I'm actually a nurse full-time), and though I've been running the TIG for about a year I recently picked up the mini-me wire gun to match. Im super thrilled with Primeweld and am proud to post them. Notice I didn't say that about QP?

So in conclusion I still am making progress and I feel like a light is at the end of the tunnel
