Default 1994 Z28, Mini Restoration and Boost

People still use these forums? Well let's give it a whirl.

Purchased this from a buddy for the grand sum of $350. I drug it home on the trailer due to a supposed fuel leak. The car is a 94 Z28 convertible. It's currently running an early 2000s LM7 5.3, ls6 intake, stock heads and cam, long tubes, PTC 3600, stock (my old one) 4l60e, Motive 4.10s, fbody 98 PCM and harness. It has midwest chassis SFCs, all AC deleted, top motors gone, and midwest bumper supports. Probably 275k on the body (LT1 lasted over 200, which met its death by eating all the bearings), 150k on the trans, rear end 25k.

She runs now, look at that oil pressure.

First things first lets get rid of the tarp (massive hole in the top). After a bit on youtube, and a $200 ebay replacement top on hand, we remove the old torn up junk. The ants that made a home werent happy with my decision.

Total time, 7 hours.

1994 Z28, Mini Restoration and Boost-nf6goa8.jpg

Now that its not leaking water everywhere inside, we can move onto the next step of the build. The god awful paint and body.

1994 Z28, Mini Restoration and Boost-n0evyxk.jpg

Ebay, $100 paint, $50 HVLP paint gun, $75 2k high build primer (grey), $75 variable speed buffer, $50 misc sandpapers, $50 Mequiars compound and polish.

1994 Z28, Mini Restoration and Boost-ajc0yp3.jpg

Jump the gun here big dummy, it needs wheels first right?

1994 Z28, Mini Restoration and Boost-ercu0zk.jpg

If you havent noticed this is a budget build and I'd like it to be a driver....so no high dollar **** here. I went with Jegs stars F+R, 17x4.5 2.25, and 15x8 5.5. Tires are Hoosier prostreet fronts, and Mickey S/S rears.

God it's still ugly. Cat not for sale. He does however think the new top is extremely comfortable to lay on, like a cat hammock. Where's the airsoft gun when you need it?

Sidenote, I already have an intercooler, injectors, turbo, BOV etc etc sitting on shelves waiting to go with this stuff.

After a little more youtubing, and talking with friends, the manual labor begins. The procedure I selected was, sand the whole car with 80, spray with the high build primer, sand the entire car with 400, spray the white, sand with 1k, 1500, 2k. Then machine buff with a foam pad using compound, then again with finishing polish. 2 coats of wax. And off we go!

1994 Z28, Mini Restoration and Boost-l5zwped.jpg

Primer, yeah its grey.

1994 Z28, Mini Restoration and Boost-motroc3.jpg

Proof.

1994 Z28, Mini Restoration and Boost-v5i0dgu.jpg

Not too shiny before the wet sanding. Hell I was just happy it was all one color.

Ain't gonna lie, I'm happy with my $100 paint.

1994 Z28, Mini Restoration and Boost-stphlhg.jpg

Old tail lights were VHT black, hated them, so I found these on LS1tech, new key lock installed also.

1994 Z28, Mini Restoration and Boost-ngmtjq5.jpg

All lights are reinstalled and working, and I added a black grill. My next focus will shift to interior (window motors, carpet, floor mats, trunk is a mess, radio and ac panels are missing etc etc). But for now, let's pull both the cars out and get their first pic together.

Attachment 713435

White one is a budget build, red one is what could have potentially been a nice 401k. Well when you die you can't take it with you right?

Damg, awesome job!!
you didn't waste anytime.
Can I suggest blacking out the head light area? That would make the car look 10xs better in my opinion.

This one is gonna be back, better then ever.

Quick pic, new floor mats (ebay), new to me (used 2002 passenger window switch), new NOS GM driver switch bezel (old one was cracked), and 2x new keyless remotes from ebay. What's not pictured is two new GM window guide felts and driver lock motor. Both installed, remotes work perfect, keyless entry is flawless. Did it ever work? Who knows, next up is complete interior revamp then boost. .02 the underside is so filthy I dont even wanna work on it, think I'm gonna pull the motor, reseal everything, and paint the underhood fresh white.

Not gonna be too many updates as i had surgery last week and the doc says no activity for a while. I have bought the rest of the turbo kit, some gm manifolds, all gaskets, a new be cool radiator to move forward and down, deka 80s, all new ptfe fuel lines etc. As far as the sanding the steps were mentioned above. Ive dabbled with bondo and an hvlp spray gun before so this wasnt a huge leap. When you sand, then let the car dry, youll see it will look like the skin of an orange, with lots of low spots. Basic goal is to get those out. Once painted, you can go too far and go through the paint, which is bad. So i slicked it down but did not remove all the peel from it on purpose. Your eyes and feel will guide you. Once you try it it will make sense. Plus there are tons of youtube videos.

Here she is, 25+ years old, a few engines, lots of battle scars. Lets get to it.

1994 Z28, Mini Restoration and Boost-vpssswt.jpg

Lots of parts going in the trash, lots of cleanup to be done. That ABS block and bracket was heavy. Fat girl is on a diet.

If you refer to the old pics, intake was silver and the whole engine was filthy. Cleaned and blasted these, -10AN welded into both valve covers that will be routed to a catch can, and a 10 drain into the timing cover to return from the turbo. Going with a clean simple look this go round. No silver or flashy colors. Imagine your spare bedroom in your house, I have that filled up with parts. Lots of fun stuff to come.
