My Awesome Girlfriend got me this XJ Pod Sub enclosure for Christmas with a JBL 8" Subwoofer. It fits pretty good into that unused space on the passanger side. I lined it with some thin foam to hopefully keep it from rattling. Since you can't have a sub without a Amp I picked up this
which should fit nicely under the rear seat.

Next up: Upgrade the fuel injectors. I found some reconditioned 4 hole Bosch injectors for $60 on Ebay. I'm going to follow these instructions provided by Dukie564.

answers have been made separately a number of times but i'm curious to ask..
What type of gains did you get for doing the injectors and intake? obviously throttle response, but any real mpg gain?
I've been planning on doing the injector swap/clean but i've wondered if the spectre kit is worth the extra $$ when i can get the cool air (in fewer words) by just isolating the intake with a heat shield.

The injectors have not been installed yet just the intake and muffler.
I can't say if there has been a MPG gain but I have noticed more pickup and go. I also replaced the CAT and Muffler allowing better flow through the engine. The benefit of having the intake feed from the cowl is the constant cold air. From my research cold air is better than hot air. the cold air is more dense so it gives a bigger bang. To sum up I definitely have felt an improvement in performance but I have not had that confirmed by any technical tests.

I found this great switch panel from Prime 4X4 It has three 12v switches and a open 52mm port. I ran my Auxillary driving lights to the left switch and found a nice oldschool looking 52mm Clock Gauge.

I tracked down a set of 5 classic Late 80's ten spoke turbine Jeep rims with Caps! I think these are great looking rims for the jeep. It will be awhile before I have the funds to get these bad boys cleaned up and hug them with some new 31" A/T tires. Can't wait!

Started installing Dynamat today. I am interested to hear the difference. I am going to start with the doors and hatch. I found 36sq Feet totaling 9 sheets on Amazon for only $143.00. Each dooor has taken One sheet each. The install is pretty simple. I used the plastic that was originally covering the door as the template. I didn't notice I was installing it upside down until I loaded the photo... Oops.

Gotta love the 92's!!!!! Looking good man, I am really curious about two things:
1) Tell me your thoughts on the new muffler (flowmaster 40 I believe?)
2) I am anxious to know how much of a difference the dynamat made, and any issues with install or if you would have gone with a different product....
Thanks in advance!

Pulled out the CPS (camshaft position sensor) and replaced it. I ordered it from Pep Boys Item BWD #CSS814. That thing is not easy to get to since it sits just under the cowl/firewall on top of the bell housing. I'm hoping this was the cause of the random stalling.
here is the old one.

The new muffler is great! I get a nice growl without it being too obnoxious. It sounds beefy enough for me. I think I posted a youtube video a while back on here to compare stock to the Delta 40.
I am still applying the Dynamat. I have three of the doors done and I will definitely try to cover the firewall to eliminate the noise coming from the cowl now that I have the Intake pulling air through there.

I swapped out the front door speakers with some JBL 5.25 2-way speakers to get a little cleaner sound. I figured since I was Dynamating the doors it was a convenient time to upgrade the sound. The speakers fit right in. No modification. No problem. I still haven't installed the Amp yet. I figure once I get the Dynamat down I can finish wiring the Sub. I think I will stay consistant and get JBL speakers for the back too.
