WAZOO Day Success 1/21/17

[Roadster]

Another great day @ WAZOO. I was the fortunate one today to have a plenum pull performed by Yun and help from Jim and a host of others. I cleaned some parts and took pics. A lot of pics to follow.
I do want to thank Yun, Jim and the WAZOO guys in attendance today. It was a very good day!!!

I will start off by saying that the time I have owned my 94, I was under the impression that my secondaries were functioning correctly. I know I had vacuum issues, but also thought it wasn't a big deal with secondary operation. I was wrong, big time. For the first time since April 2014, I now have full secondary operation. And all I can say is......wow, I'm stunned. In the past I was able to pull shifts @7200r's whenever. Engine felt good, no stumbles, no hesitation, etc. Just thought it was running great. Had my vacuum pump unplugged, and figured when the plenum pull gets done, will address the problem then. And having never been in or driven another ZR-1 before purchase, what did I know!!! Well I really didn't know anything. I just knew my Z was running good and I was satisfied.
Well after today's pull and test drive w/Yun afterwards, it was like this LT5 is totally different. Not only can I feel the additional power, but the sound of the secondaries opening is music to my ears. It was like buying another ZR-1.

Here is the list of items done today and why they were done. I figured if we're doing the plenum pull, we may as well do it all or as much as I can. Because I don't want to get under there again, unless it is absolutely necessary.

1-Plenum Pull
2-replace starter
3-replace coils
4-replace vacuum lines
5-replace check valve
6-replace filter
7-replace PCV valves
8-replace PCV hose
9-replace MAP connector
10-replace Fuel Regulator hose
11-clean the valley
12-unclog the drain
13-clean Plenum and other parts
14-replace Fuel Injectors
15-replace alternator
16-go for a test drive and smile.........

On a side note, I decided to keep the secondaries factory, and not do a coolant bypass.
Also already having Marc's chip, gives me another 10HP (415HP now), who can argue with that!!!

And Charlie, you also were so right about the secondaries.....oh yea!!!

My injectors were original, and they all tested out between 12.2 and 12.5
They were still good. But I took advantage of a sale through an email on FIC and went with new. Coils were MSD units and purchased through Summit. Jerrys Gaskets provided all of the hoses needed and other small items, from my purchase which turned out to be a great move.
While the main vacuum lines were in good shape, we found problems with the check valve (which was very loose in the connection) and the PCV hose that was split. We replace the vacuum hoses anyway even if the old ones were still good. We're in here, so let's just do it.
Again, results were phenomenal to say the least. My vacuum pump works flawlessly and is tight. No leaks.....
Enjoy the pics.....
