Re: Pulling the Plenum for the first time...

The o-ring's are either ethanol compatible or not? Does anyone have the sizes for the o-rings required? I thought new fuel injectors come with the the o-rings required? I am looking at getting the Accel Fuel Injectors. In the past when I purchased new injectors they came with the little orings already in place. I need to have all the parts ordered before I start this project. I don't want to be waiting on parts.

Re: Pulling the Plenum for the first time...
Knowing that major manufacturers use the lowest cost part that meets specs and mark it up as much as possible, when I buy parts I research who makes the OEM stuff and then which manufacturer makes the very best part, then I search for pricing.
When I use orings I most likely will use those that can handle nitromethane, the very highest in quality, as long lasting as available, and 2 floors (not steps) above those required in specs. Gasket materials are all over the place also, I use solid copper gaskets on exhaust anytime I am able to and use a manufacturer that uses the same specs from the Chesterson 140 gasket material or make my own. I only like to do things once, so I will pay more for the parts and components or make them to make sure of it. Jerrys has the gaskets/orings and so do other sources.

Re: Pulling the Plenum for the first time...
Has anyone ever made their own map hose? Is it recommended to replace the spider of vacuum hoses with all soft flexible ones like silicone?

Re: Pulling the Plenum for the first time...
I made my own map hose w/ 1/4" hard plastic hose and rubber hose from Advance Auto. You don't want to use soft flexible hose for vacuum. Vacuum will make them collapse and inoperable.

Re: Pulling the Plenum for the first time...
When I did my exhaust, she asked how much? I said about the same as the new couch you're looking at. I had to wait. Don't buy Lazy Boy buy the way.

On my 944 Turbo I used all silicone tubing for the vacuum lines. It worked great. They were oil resistant and everything.

You may want to check with Eaton Aeroquip for hoses, they have every kind and size that will take anything you put into them.

Re: Pulling the Plenum for the first time...
Now the fun starts...
Marq21 and I pulled the plenum on the ZR1 yesterday. Need to give him a shot out for helping me out on this job. Without him I would have not been able to fix the secondaries issue I was having, or get the complete job done. First off, WOW. The car runs completely different. I don't even know what to say. If your car doesn't surprise you every time you hit the gas WOT, then you need to get some service done. My car is having an intermittent high idle issue. It doesn't sit at the prescribed 750 RPM. It idles around 900 rpm normally, and occasionally after coming to a stop will be at 1200 RPM. With a Tech 1 hooked up the IAC shows 0. It occasionally would move, but at idle it was 0. I have read there is IAC re-learning procedure that can be done. The battery was unhooked for a few hours. I have the FSM, but I don't know the correct search terms to find it. -Vacuum leaks were fixed -Plenum gaskets were in good shape so they were re-used -Accell Injectors were installed -Check Valve replaced for cruise -PCV Breather hoses in the valley were replaced -New MAP hose The car runs great throughout the RPM's now. It drives great, except idle is a little weird. In between gears the idle will kind of hang around 1500 RPM.
