Of course it had high miles and wasn't in the best of conditions...but still....15mpg...wtf

i dont mean to barge in this thread, and i know theres a huge *** thread on this, but, how much money, more or less, not including drive train, would it take to swap an lsX into a Jimmy/Sonoma?

Only things holding me back are the facts that the truck is an OBDI vehicle, it's 4x4, and I don't know how many local shops would be willing to tackle the project.

1.) Oilpan: You need a custom piece. Fabricate your own (my method) or buy one (Turbotime is supposed to be making them for ~$500)
2.) Exhaust: No stock manifolds fit without modification. They can be modified, but you're on your own there. There aren't commercially available headers either.
3.) Engine / Transmission / Tcase location is much more critical. For a 4wd you've got 2 driveshafts to worry about and pinion angles on 2 pumpkins to make sure are correct.
Good luck finding a shop to tackle it. There aren't many who would be willing to take it on. And you'll pay for the ones that will take it on. But that's my opinon.
Here's what I can tell you: I've got about $7k+ in my conversion. That includes a good used 6.0L ($1200) a good used 4L80E (don't like the 60E in an AWD application, $800), a rebuilt transfer case ($1000), reprogrammed computer and a complete new harness ($1100) and converting my truck motor to C5 accessories (probably another $500). I built the oil pan, exhaust from the motor to a JBA 3" Cat back system ($300), and transmission crossmember. Basically everything between the AC condesor and the axles were either replaced or modified. I did all the work, and worked on it a fair bit every week, but not 80hrs a week (probably 25hrs a week with some vacation time in there too), which is why I started in April and it wasn't done until October. All in all, I'm pleased with the results.

Element, if you wanted to go a GEN 1 motor like a 5.7 TPI, or a GEN 1 with TPIS Intake (similar to the LT1 intake), the oil pan, headers, radiator, good instructions are available through JTR.

After doing some search and some research.I'll stick with my original plans on the ls1 and not do the ls2.Do my bolt ons and be plenty happy.Still think I'll be able to get at least 15-18mpg with the Patriot heads and cam,I'll be happy.

what all stays and what all needs to be deleted on the computer as far as the tune ?Does the deletion of the EGR have ANY affect on mpg or anything else as far as that goes.It wont have the cats on it or the rear 2 o2's,I know that much.
