My boy is pulling out his ls2 from his 05 gto, he said i can have it for 3 G's to put in my 71 chevelle. is that possible? and if so, is it worth it? stupid question to some, but i really need help.

Man those are sweet engines.....not sure but I think it's the same as putting in an LS1, which I know a few here have done.

What's up with the GTO? Wrecked it?

Easy swap, and that is a good price, buy it, but make sure it comes with the entire turn key motor including pcm. If it does not, do not buy it, it will cost to much to piece they rest of the parts together.

Doesnt Painless make a wiring harness for retrofit applications? That would be a cool swap.

The painless harness os only for 98 pcm's, they are are bad year and for ls1 only unless they came out with a new one.

I would search the pro-touring section here and Ls1tech.com conversions section. Plenty of Ls1/Ls2 swaps.

Yes it can be done. You will have to swap the GTO oil pan out for another pan. The pan you use will depend on which motor mounts you use.

Hes just upgrading his gto to a bigger engine... my budget for the whole resto is 12 G's... can it be done? new engine, tranny, interior, body... plus labor

milodon makes an oil pan for the LS series engines that does not require any cutting / welding / fabbing of the crossmember. http://ls1tech.com/forums/showthread.php?t=604174

street and performance, FAST, Katech, Arizona speed & marine as well as others have the ecm's and harnesses.

I'd say go for it myself :thumbsup:

No.:sad: But it does'nt hurt to try!:thumbsup:

I've always wondered how much wiring you'd have to do if say you got an LS1/LS2 engine with ECM and wiring harness and swapped it in an older model car?

Obviously you'd have all the connectors coming out from the ECM to the injectors and whatnot...I'd imagine there's a few 12 volt + inputs to the ECM to make it work....

Quite a few people have done it. If you aren't good with wiring or just don't want to mess with it (me when i was considering this), Edelbrock and GM Performance both make carb conversion kits. Put a new manifold on it, throw a 4 barrel on, and plug in the provided sensor control module to your wiring harness. Get all the benefits of modern engine design without making a couple hundred wiring modifications, less the fuel injection of course. I think the edelbrock kit comes with the manifold and control module for somewhere around 600 bucks. You can probably sell the fuel injection system to make some money back though. Check out the hybrids/conversions forum at www.ls1tech.com , tons of information, how tos, and picture tutorials... the best place on the net to learn about LS motors and swaps if you ask me.

I agree the carb idea is a great for someone who does not want to bother with wiring. Also if it is coming out of his son's GTO he maybe keeping the intake, tb etc and would keep the harness and ECM. You can always convert over to FI later. LSx motors are addicting low weight, tons of available parts, great power, and good gas mileage. My C5 managed 29-31mpg on the hwy with heads and cam making the #s in the sig. The mid year Corvette guys also commented that it sounded like their side pipe car did when they were young.

http://www.speartech.com/ has everything you need for the harness and ECM. The Ls2 is a Gen4 for motor and while most of the internals, heads, intakes, etc swap the reluctor wheel on the crank is not the same as the Gen3 LS1/6, LQ4/9 etc. The ECM or reluctor wheel must be swapped to match the other

Have you priced the harnesses? Make sure your sitting down! It is not hard to modify your own. Basically you are mostly removing wires for all the emmission junk. It would take the average Joe a whole weekend to modify, but that can save you $700!!:beers:

I agree but alot of people are afraid of EFI enough much less to hack into a harness. Just depends on where they see their limits and what their time is worth.

All I can really say is do your research, there are 100s of options and ways to do the swap. Advice from people who have been there and done the swap is greatly appreciated :beers:

Anybody have an idea of how much itd be to get EVERYTHING done under the hood? everything new... new tranny, rear end... whatevers needed.... i really am that clueless...

im swaping in a '04 lq9 (ls series engine) into a '69,, or will be in a month when it comes back from paint,,, as far as costs, depends on how fancy you want,, the engine w/ harness and all accessories will probably fall between 4-5k, my harness had been reworked and had unneccessary crap removed and i got it for 4330... im going to be running a 700r4, so another 1500 or so,, and a 9" w/ detroit, moser shafts, and discs--another 1500 (got that already),, then i still need a radiator, driveshaft mods, headers, exhaust, hoses, fans and other stuff--1200+,, so im personally looking around 9K for my complete drivetrain.. it aint cheap but then again, sweet carb'd crate motors aint that cheap either and would cost me almost the same..

:thumbsup: Thanks for everyones advice and opinion...

Is the 9" really needed? If he does not plan on drag racing or running slicks a decent 10 bolt maybe all he needs if he currently has working posi.

Just some ideas on getting the swap a bit more cost effective. As others have said it really depends on the route you take and how much work you do.

Well its not like your going to get the wiring if he is swapping the motor. So chalk up for one new wiring harness. As for the ECM, its more then likely he will have that re-flashed for the new engine also. Much of this is not all that different then doing an LT-1 swap.

wiring is not going to be as bad as finding all the othre parts. the gas tank has no return lines for fuel injection. all new fuel lines? why run an old trans when you can run a new one with all the new computers? the carb idea is nice, but you get nothing if you do that. i have thought about this, but $1,200 for a 454 that gives me old school performance(gen IV(4)motor) seems like a better deal to me. i love the ls motor(the ls6/ls7 is what i want.), but i will take a big block just becouse it is cheaper, and less of a headach.

While I agree the LSx would not be optimal with a carb and original trans, it does get the motor in and running quickly on a tighter budget (than a full efi/over drive trans). You can add the FI and 4L60E or T56 later. It really depends on what the owner wants and can afford. A mild 454 is hard to top for a weekend car to cruise around in.

It will be faster to get it running with the factory EFI. You hook ups some power and ground wires, a fuel line, and it is running. With the carb conevrsion, you beed a ton of money for the conversion, and have to hoo up the new wiring anyway...correct?

that's just the setup im going with, it can definitly be done cheaper, or more expensive than mine.. i went w/ the 9" because i didnt want to go through rebuilding my 10 bolt (would need a complete rebuild--swapping gears, new bearings/seals, new posi, disc brakes). the 9" allowed me to start fresh and and eliminate the c-clips while i was at it..and i've seen my buddy blow up the ring and pinion in his 10 bolt a couple times in his camaro..

but yes, using his stock axle and retaining his existing tranny, it can definitly be more cost effective and still run great :thumbsup:
