1988 B2K 064 coming back to life

Post by sjandras »

My first post after watching and reading for many years. I just purchased 1988 B2K #64 after it went through years of deferred maintenance while in storage. It was also my first experience buying a car and having it shipped sight unseen, but it was a gamble I was willing to take. Stressful and a rollercoaster for sure, but I'm now content with my purchase after a few weeks of fiddling. The story is that that car was driven 14k miles in the first three years, then sat in the warehouse of a well known midyear Corvette restorer until 2019. He then sold it to a dealer, whom did some hokey things to "get it running" for sale. I spoke to the long term owner before purchasing to confirm the story and it all added up.

The car arrived in an enclosed carrier two days after the deal was finalized, then the work started... So far: replaced plugs and wires, replaced a few leaking oil hoses and AN fittings, vacuum leaks, EGR plumbing done wrong, cold start injector was stuck causing a horrible cold idle, microfueler functional confirmation (which helped me figure out the cold start injector issue!), serpentine belt replacement, new brake rotors, pads, and full fluid flush, and headlight motor rebuilds.

I'll post some troubleshooting lessons I've learned for future reference soon. I hope to bring some life to the forum, I do think these cars are under-appreciated and they need more attention!

As of now, I've put about 100 shakedown miles on it after truly "getting it running" and it was all worth it! Next on the list are: trans fluid replacement, overdrive troubleshooting, coolant flush, freon leak check and charge, Bose amp swap for Maxima units (as I did on my ZR1), antenna rebuild, and I'm sure a ton more as I start to drive it and more stuff breaks!

Wow!!

Which "Corvette Restorer" had the car?

And what's the skinny on the Maxima Bose parts? :wtf

Keep up the good work!

It was owned by Gary Naber in Houston. He also did some minor body work on the hood and some paint touch-up work on it early in life.

The Nissan Maxima Bose amps are a near drop-in replacement for the Corvette amps. Pre-91 you need to buy pigtails and solder them on or solder direct like the factory amps. Tuning is a bit different, but it beats a non-functioning system. There are a few posts on zr1.net with details. I found a dozen of them in a local junk yard for $5 per amp a few years ago.

It was a productive vacation day in the garage. The AC now works after tightening one connection that was loose for some reason. It holds pressure now and blows ice cold after being vacuumed and charged with R134a.

I also swapped all four amps out, the stereo sounds good as it ever did. The front speakers on the pre-90 cars are a huge pain because the door panels need to come off. Overall, still not too bad for about four hours of effort to do fronts and rears. See a couple pics below for the old amp vs. the new Maxima amp installed on one of the rears. Yes, hole pattern is identical, literally drop in replacement. Two wire positions are swapped, that's the only difference and easy to correct while soldering in.

I love this tech tip. Thanks for posting, and for joining the forum!!!

Gary Nabor - a great name, legendary for midyear restorations. Sorry though, don't see any connection or value with him for the C4+ cars. Perhaps this is evident in what you found, too. There are some good C4 shops. Corvette Center in CT is one, and there are some others around, too.

Yes, agreed. For sure no value add based on who owned it. It's just piece of mind knowing that it wasn't hacked on by a bunch of random owners over the course of its life. Will keep posting updates as relevant. It's fun getting back into C4s after a few years away.

Still slowly poking at the car to make improvements where needed. I decided to dig into the intake to try to find an elusive vacuum leak, I think it is the runner to plenum on the driver side. It likely was not assembled correctly by the dealer's mechanic when he replaced injectors based on other handiwork I've seen.... While it's apart, I'm also doing coolant hoses and a new aluminum radiator. I'm going back to the OE hose/ thermostat configuration, which I've read Callaway now recommends.

A few issues along the way.... Every hose I touch breaks or frays when getting off the barb. The worst is the turbo coolant line that goes from the driver side radiator end cap to the turbo banjo fittings. That one snapped as if it was made of plastic, super brittle from time and heat! Now looking at how to replace, I'm curious how you get the banjo fitting off the pass side turbo? Is it possible without pulling the turbo or engine?

Is there such a thing as a Callaway service manual supplement?

Thanks!

Wish I could help you on this one, but I don't know. Certainly pulling the turbo is a much easier way to get to the banjo fitting...
