Tips on removing the intake manifold?

[Chris]

Anyone have any tips or suggestions for removing the intake manifold (going to install my supercharger) on my 05 Wrangler TJ?

I know how to remove it, I was just curious if there's anything I can remove or do to make the process easier?

Thanks in advance!

You'll need to start by removing the exhaust header. The biggest thing to keep in mind when replacing the intake manifold is not to rush it. Take your time, then take some more time to make darned sure it's seated properly and sitting correctly over the positioning studs on the head. It's very easy to not get it seated perfectly which will cause a huge vacuum leak and sky-high engine RPMs when you first start the Jeep afterward. That really sucks because it means you have to start over.

If there is some lead time before you dig into this project I would spray the nuts and bolts with PB Blaster to include the exhaust manifold bolts as well.

And to echo Jerry, be aware vacuum leaks on the 4.0 can lead to catastrophic engine failure due to the fact the 4.0 runs leans from the factory. There is no way to alter fuel tables in the factory PCM. Adding a SC or TC is always a stress on fuel management with the already lean running 4.0

Good luck and keep us posted on the build.

The best possible advice I can give on this matter (after having done it myself), is to remove the driver's fender. Removing the fender makes what is normally a huge pain in the ass job into a walk in the park.

Honestly, it might take some time to get the fender off, but you'll save yourself so much headache.

When you run out of PB Blaster, try some Kroil and see what you think. My bet is you'll see a dramatic improvement in how well the Kroil works. Even Break-Free. PB-Blaster is pushed hard by the chains but I'm no fan of it. It's definitely better than WD-40 though.

You now have a supercharger on your TJ? What exactly is that?

Have for a long time. It's a Eaton M90 supercharger.

I am curious, was wideband hard to locate and install on the 4.0? What device you are using to alter the maps?

Too cool!

I'm using a Split Second controller. No need for a wideband. It piggybacks on the stock ECU and adds more fuel via a 7th fuel injector.

Nice! Got any pictures or videos?

No, but I'll need to take some at some point. It's quick as hell, I'll say that much. Put the pedal down and it will just burn rubber!

I haven't had it on a dyno, but they claim something like 220hp at the wheels on a stock 4.0 (which is a lot). I believe it too, because the difference was night and day.

Yea I would like to see what a dyno tune could do for you.

Yep, I'm just running the "base tune" which is meant for sea level altitude (which I'm at) and a stock 4.0. I'd bet once I dyno tune it, I might get some extra power out of there.

100% agree with taking the drivers side fender off. It will save much frustration.
