My LS3 Swap
After months of debating whether to rebuild the old tpi, or to get my dream motor (any ls motor but the LS9 would be badass). I figured well ill be a wicked 383TPI and have tons of toqure, but with the greatly popurlar ls swap (and growing) i figured nows the time to do it and stop talking about it. ive been wanting this motor, just kept talking myself outta it because of the about of money required to do it.

Re: My LS3 Swap
As you see in my sig i have quite a bit into this motor, many just bolt ons(which now are for sell, if u guys are interested(headers are already gone). With this being my first swap, i wasnt really for sure what i was getting my self into. talking out the old tpi was not all that bad..

Re: My LS3 Swap
Looks like you've got yourself a good start and you'll love the LS power, are you going T-56?

Re: My LS3 Swap
I got a GTO K&N kit (I have an LS2) and then modified it to fit down behind the driver side headlights. A more cost effective and perhaps even less restrictive solution would be to make your own, and a lot of guys have done that, using PVC pipe and some couplers I think. This company has individual parts that you could use to piece together your own: http://www.siliconeintakes.com/ I got my extra couplers from them.

Re: My LS3 Swap
I would have bought and built a 6.0L and bought a T56 too instead of buying an $8200 motor and using the stock auto trans. But to each his own

Re: My LS3 Swap
you may want to get the prothane motor mount insert... it is much better than the stock rubber and is easy to install in the stock clam shell
it is a lot tougher to do after the fact

Ask me, I know. (700r4 -> 4L60e, stock kmember -> tubular, stock mounts -> poly, etc.). If you're cutting corners in the name of cost cutting that will continue to nag you, just put the project down for a few months and build up more funds.

Re: My LS3 Swap
Fbody T56 will work fine. Be sure the clutch is stout enough to handle it
Match the starter to the bellhousing. The only non interchangable ones Ive seen are GTO T56 vs everything else

Re: My LS3 Swap
Yeah, I felt the same way at first, but now that I've had to shell out the cash for the used motor, the machine work, the rotating assembly, the heads, intake, etc... I'm quickly realizing that a crate motor really isn't always a bad investment... especially considering that it's getting close to a year since I bought my motor, and I don't even have it assembled yet.

Re: My LS3 Swap
You should only have one steam tube connecting the fronts of teh cyl heads under the TB. The back of the heads should have a blockoff plate. (I assume the LS3 is the same setup...) Asfor teh cooling. I'm using my astock tank and rad. Running the steam tube vent to the opening right above the transmission cooling line on the rad. Other then that everything else is the same.

Re: My LS3 Swap
the corvette center dumps that were origanally installed on the ls3 were not used due to fittment issues. i kinda figure they wouldnt but was hoping for it.

Re: My LS3 Swap
1. the orignal witing harnnes was removed
2. the ls3 was pulled back out for clearance issus with the vette oil pan the cross member will be notch to make room. side shot of ls3 with camaro manifolds installed(orignally the ls3 was build with the center dumps installed but the package i ordered came with the camaro exhaust manifolds just in case the vette center dumps wouldnt work).

Re: My LS3 Swap
just the engine alone is not 8000 it has the harness ecu and other stuff included in the package.
update..harness is out ..and motor was dropped in but the oil pan on the ls3 will not work with the stock k-member so i had to order a new oil pan kit pn#19212593.
keep u guys posted

17% drivetrain loss says it should be around 367hp, sooo like a bolt on ls1? I realize its cool to have an ls3, but i dont see it being worth all that extra money.

Re: My LS3 Swap
Yup. This is an option id like to work with in the future.. bigger displacement is better . When I did the ls swap years back I wish I could've done a ls2 swap. Now id like to go with a ls3.. I wanna go heads n cam on my build but ill rather wait
