My '90 ZR-1 project update thread
Thought I'd start a new thread and post updates and pictures as I progress. Go to this link to for the beginnings of this project:
http://www.zr1.net/forum/showthread....ight=bdw18_123 I'm still in the 'cleaning everything real good' stage, which is turning out to be a very large project just by itself. I just can't stand putting something back together dirty, even if it takes a lot of work to get it clean. The previous owner replaced the fuel injectors, but I didn't know where he got them from. Then I happened to look in the bag of the old, original injectors and I found these: http://i13.photobucket.com/albums/a2...3/STA70002.jpg Which was a pleasant surprise as I have heard nothing but glowing reviews about FIC, so I know the injectors are good quality. Here are a few before and after clean-up pics: Fuel injector rails & IH's before http://i13.photobucket.com/albums/a2...123/IHs_b4.jpg Fuel injectors & rails after (also installed the new fuel pressure regulator, which came with the car) http://i13.photobucket.com/albums/a2...3/STA70001.jpg IH assemblies after http://i13.photobucket.com/albums/a2...3/STA70003.jpg http://i13.photobucket.com/albums/a2...3/STA70004.jpg |

Throttle body & airhorn after
http://i13.photobucket.com/albums/a2...3/STA70005.jpg http://i13.photobucket.com/albums/a2...3/STA70006.jpg Alternator before http://i13.photobucket.com/albums/a2...ernator_b4.jpg Alternator after (I painted the aluminum case halves with paint that imitates new cast aluminum look, cleaned interior of alternator also) http://i13.photobucket.com/albums/a2...3/STA70009.jpg http://i13.photobucket.com/albums/a2...3/STA70010.jpg The plenum, IH's & airhorn/throttle body cleaned up pretty good. There are some stains I can't get out and the top of the throttle body has an area where the coating is missing, but they look much better than before. That's it for now. :thumbsup: |

Ben:
Looks like she's cleaning up really nice. :-D One small thing though... There is a ring of special sealant called "DAG" around the blades of the throttle body that seals the blades and helps with the idle. Hopefully, you accidentally didn't clean it off too... http://www.zr1netregistry.com/forum/...32&postcount=9 TomC "Crabs" |

Ben:
I don't think it's something that you can buy at the local parts store, I've never needed it so I've never looked. If you've cleaned the bores 'till they shine, then it's gone. My thoughts would be to put it back together and if your idle is *way* high, then think about finding some or have the throttle body serviced by a pro. I know that Marc Haibec offers a rebuild service, here's a write-up over on his website. http://www.zr1specialist.com/HAT%20W...tle%20body.htm TomC "Crabs" |
