I was wondering if the 6.0L Gen IV LS2 Engine that comes in the 2005 GTO is a direct bolt in for the 98+ LS1 cars? From what I can tell the two engines look very similar. Thanks.

 

If you used the 05 computer and sensors. And you'd have to fab up an intake lid adapter.

 

Wait a little while and the Crate Engine will be available.

 

Yes, it will physically bolt-in direct, but as mentioned, you'd need the computer (or at least some serious tuning done to the LS1 computer, if it would even work at all? ) but other than getting a slightly larger bore than the LS1, there's nothing to be gained by dropping in the LS2 that you couldn't get by doing a heads & cam swap on your LS1. You'd actually end up further ahead, and probably less money too.

 

you can get an engine from gmpartsdirect.com already...and it's cheaper than buying the ls1, drop in ready to roll. but the thing is, ls1/6 parts are readily available and cheap.

 

You can also get the 402 LS2 shortblocks from Scoggin Dickey Performance Parts now.

 

but the allure of the LS2 for me is good power with no mods.

I just do not want to mod any more cars.. Lately I have been thinking of dropping the GTO drivetrain and LS2 into my porsche.. that would be hella wicked..

 

Yes, that would be cool as heck!!!

 

i didnt see the ls2 for sale on gmparts direct or that scrobby diggens place.
