Hi I recently purchased a 996 with a blown motor looking to swap it out for a LS3 looking on some advice on mounts what company and other things that might be helpful with this engine swap thx

I think Renegade is a kit, I saw a 996 narrow body with aero kit with one , looked pretty good , sounded great.

ls1tech.com decent group minimal drama, they like the swaps, and there are a few on there,, expect to be up
to15K ish into one unless your a real do it yourself-er to the core.
Renegade Hybrids and Kennedy are purveyors of many of the needed/handy parts.
A Turbo style transmission with cooler highly recommended.

Don't fixate on the LS3, there are several options that are more economical IE a L92 is about 5500
in my area(With < 100K on it) ,, its a Escalade all Aluminum 6.2 and your into the 400 HP zone
STOCK. minor tweaks and 500+ and less of the Corvette Legend tax.

Shamelessly plagiarized from the web:
What is the difference between l92 and ls3?
LS3 Heads and the L92 heads are Identical.... only difference between these 2 engines
was the cam and pistons other than that they use the same heads. LS3 intake valves
have a hollow stem, therefore lighter. LS3 heads are designed with hollow valve stems for higher revving.

There's a few in the Facebook group.

I have an Ls2 in mine. I would personally stay away form Renegade. If I had to do it again, I would buy everything from Andrew (Stuttgart Muscle). Things like engine mount plate/mounts, gas pedal adapter and harness for the C7 pedal, clutch flywheel and trans adapter (although that I would get from Kennedy Engineering personally). Everything else is off the shelf, wire harness, headers, starter and manifold all fit. Exhaust you're left with a custom fab job no matter what. Hope that helps.

I am gathering parts for mine. I picked up a renagade engine mount as a good price and i like the sage 2 spec clutch and adaptor by stuggard muscle. im probably gonna build a 8k rpm destroked ls3. I toyed around with the new supercharged lt4 but i think its too much. I have already got upgraded radiators and will probably do the center rad just in case. All the info for the swap is out there u just need to dig.

Any idea where Stuttgart Muscle is located?

Don’t think a GM motor won’t need oil mods if you plan to track it. Otherwise, the LS swap is awesome, albeit not easy or cheap to do.

Thx I will look into Stuttgart muscle looks much cheaper

This is my 5k project I got from a guy that got it from the auction

Had some time today and pulled the engine out

already looks like a great start. They only thing I would ask about the Stuttgart Muscle adapter is if it clears the sway bar, otherwise the KEP adapter is the same price. The Kennedy unit comes with a clutch kit (I'm currently running it now). Handles 500 hp and is very street friendly. I've owned BMW Ls swapped cars, driven swapped Rx-7's and a v8 boxster. The 996 is by far my favorite.

U can starve an ls of oil too. The higher end ls cars r dry sumped motors and im planning using the factory system on mine.

I'd love a "simple" LS1 swap into mine.

Having a '99 makes it considerably easier from what I understand.

Enjoying my 3.4 for the time being. Will look into it down the road for sure.
