Need help reviving stock 89 CRX HF

[grandmacrx]

Greetings all!
I was fortunate enough to live next to an older lady who has owned this 89 CRX HF since new. It was her husband’s car. He passed away in 2006 and the car has been sitting in the garage since. She did tell me that the car was serviced by Honda dealer within the last 10 years. The car has 48k original miles. Next weekend I plan on changing all the fluids, battery and filling the tires with air. I would prefer to keep this car stock as much as possible with exception of converting the rear breaks to disk and replacing the exhaust.

My questions to this community (budget isn’t an issue):
- what would you recommend replacing right away for a tune-up the right way?
- what brand and type of exhaust would be closest to stock?
- the undercarriage is in an incredible condition and I would prefer to keep it that way. What type of coating do you recommend for undercarriage protection?

Thanks everyone for your time!

The car is a 90-91 car, FYI, based on the front bumper cover, tail lights and seat belt style (door mounted).

-Replace all the typical things, plugs, wires, distributor, fuel/oil/air filter. Change the trans and brake fluid.
Check all the lines under the car, fuel and brake. Check the brakes, sitting for this long, you're better off changing.

-Exhaust info, it's a few years old but still applies.

-I wouldn't undercoat it. If it wasn't done from new and was driven at all, to me it's a waste. You'll never get it clean enough under it now to have the coating actually do anything. It may trap debris and rot from the inside out.
I would drive it and be diligent with undercarriage, automatic, car wash cleanings.

Thanks for the info! I am a noob to CRX. I am just fascinated by this little car! I figured it was an 89 because that’s what I saw on the door sticker. But I just checked the title and it does say 90.
Would you convert the rear breaks to disks? Since the car is so light does it really make a difference?

I would change nothing. With that kind of mileage on the clock you have essentially a museum piece. Treat it accordingly.

No. Replace what is needed. If it needs rear brake work, just replace with drums, shoes and hardware as needed with the same parts.

Keep it as is, get it mechanically reliable and enjoy it.
@ under 50k, it's got lots of life left.

Thanks everyone for recommendations. I decided to keep the car as OEM as possible. So far I replaced the plugs, wires, pcv valve, brake lines, master cylinder, rear drums, rotors and pads. The 13 inch steelies were driving me insane thou so I put some 15inch GSR blades and now the wheel gap is driving me crazy

I also discovered that the left front shock is leaking. Thinking about replacing the struts with Skunk2. Any objections on going that route? Should I go with another brand?
