Lol I knew someone would notice that.

I have IRO long arms and I boogered the holes when I drilled it for the LS trans mount.

I have the entire seal coated right now with permatex red and it still leaks.

I picked up some Mopar RTV that I'll be using this time.

Re: Projext "V8 XJ" Build

2.5" is what I run, did a lot of testing. No real benifit to running 3" with a stock 5.3. I also have a dump right after my cats and I have checked fuel trims and MAF readings and they are the same at WOT both with the exhaust dumped and running it all the way out the back. My guess is maybe a 10hp loss at anything over 4k rpms but really have nothing to back that statement up. I would run 2.5" for ease of install and long term longevity (rock clearance etc).

When you want to be someone you drive a lifted JK, when you already know who you are you drive an old XJ.

Re: Projext "V8 XJ" Build

Anyone know a source for that y-pipe, non-stainless?

EDIT: nevermind, surprisingly inexpensive at Summit, and on the way...

Re: Projext "V8 XJ" Build

If I were to build an exhaust any Idea on what bends I would need for the header back?

I think I'm going to do 2 1/4" from the header to a 3" collector and back.

Re: Projext "V8 XJ" Build

Just ordered a Hobart 210MVP, Evolution Rage 3 chop saw, 2lb spool of stainless wire, and some welcome welding PPE.

I'd like to build a welding cart and a welding table so I have some work surfaces.

Ordered everything for the header back exhaust. I'll be learning how to weld on exhaust pipe. Here's to hoping I don't Fail!

Re: Projext "V8 XJ" Build

the early LS1 (97-00) manifolds are not so expensive. but the late LS1 (01-) are the same like LS6 monifolds and they are expensive.
I bought the early LS1 for 200,-

Re: Projext "V8 XJ" Build

Good looking setup. I'm using the same style manifolds. I wish I would have used V-bands.

Because everyone figured out that they make nearly the same power as a $400 FAST intake.

97-01 I think are all the same. LS6 are 02-04. I've gotten lucky and picked up a couple 97-01s locally for under $200. I use a Craigslist notification extension for Chrome Checks for what I am searching for every 5 minutes.
