I'm thinking about the swap to a V8 in my 2.8 camaro.

I have a buddy thats offering a LS2.
Would all the stuff be the same for the harness from the LS2 car that i could splice in, or should i just go classic LS1?

Depends on his offer. The LS2 has the potential for more power because it's bigger. And most LS parts are pretty much interchangeable with fuel and stuff so it all comes down to your goals and budget.

 

are you can use an LS1 computer and Wiring harness on an LS2 if you swap the sensors from the ls1 into the ls2 and use the ls1 throttle body. All the accessorys are interchangable. I would use LS1 style brackets for your accessorys, and proabably go with the ls1 oil pan. everything else is pretty much interchangeable.

 

You'll have to get pinouts and figure it all out if you use the ls2 harness. Shouldn't be hard to track down pinouts over at ls1tech. If you end up using the fbody ls1 harness you'll need a couple adapters for your swap. camshaft position sensor was moved to the front cover instead of the top back of the block. the knock sensors were moved to the sides instead of in the valley cover like the ls1. i'm not sure if the ls2 injectors are the same as the ls1 or not. i did an ls3 swap and we had to get injector adapter plugs also.

so you need:

knock sensor relocation
camshaft position sensor relocation

seems like im forgetting something... maybe not...

 

Dont forget the 58x crank

 

Alright thanks guys. He's been pretty generous with stuff before so it may be pretty cheep.

But, now i'm kinda wondering, Should i just get a 350 block, and build it the way i want to.

If i did that , should i modify the car, or try and get a LS1 set up like yall said if i was getting the LS2 and it should be close to fitting,right?

 

If your wanting to do a modern 350(ls1) 367(ls2), then I would just pick up the LS2 from your buddy and use whatever intake/exhaust manifolds come with it, and whatever accessories you can find. you will probably need the LS1 oil pan but everything else will be the same. The wiring is going to be about the same regardless of which harness/ecm you use. The pinout information and wiring information is widely available. I wouldnt try to build an older 350 unless you are really on a tight budget. LS parts can be found for pretty cheap and they are great motors. I currently have an LS1 in my RX-7... I am considering getting an LS2 or Lq4 block and building a 408 stroker motor. You can pick up the Iron Lq4 block for under $500 and build a monster that will take boost/spray. Or do the same with the LS2 aluminum block and keep your weight down and dont run as much boost if you go forced induction.

 

some unfortunate early GTO owners got ls2's with 24x wheel :\

 

That would be great from a harness building standpoint because Fbody stuff would work. All the 24x GTOs Ive seen were 2004 5.7L LS1's. Then again I dont pay much attention to GTOs

This bugs the hell out of me, esp when I see 350 plastered on LS 4th gens. Its a 346ci engine

 

that was it. for the ls3 we had to have a 24x reluctor put on the crank to use ls1 electronics. and we also had to change the camshaft gear but i dont think that applies to the ls2. the 04 gto came with an ls1 and had a 24x reluctor 05 had the ls2 and it was 58x. if you use ls2 wiring and ecm you wont have to do any of that.

edit: you beat me to it
it pisses the parts store people off they all have them in as a 350. so when i call they're like what size engine. 346 is my answer and it gets silent. like uhhh its not in here as an option lol


also the LS2,LQ4,and LQ9 arent they 364ci instead of 367? lol typo i assume on the keypad

 

yeah stupid parts stores. I always tell them to look up a chevy 350, and they are like whats it in... Im like "a mazda" and they get all kinds of confused. to save time and frustration i just have them look up the vehicle the engine came from, because most people that work at parts stores are pretty stupid. (there is always an exception to that, but in general... stupid)

 

Lingenfelter makes a box that you hook up to your wiring harness so you can use a 58x reluctor wheel with a 24x computer/harness. If you found a nice LS2 block and didn't want to tear it apart to replace the wheel, and wanted to use all LS1 fbody accessories and computer/harness, that would be the way to go.

 

Well, i think i'm going to back out on me getting the LS2.

I went into an audio shop today pricing some stuff for the maro, and turns out the guy has an 84.

well he wants the LS2 and will basically give me his 305 and the K frame, just for the hookup. So, i guess now i need to get a 305 TPI harness and whatnot.

Then, i can toy around with the 305. What kinda heads can i bolt up to it?

 

Swapping IN a 305 is like competing in the special olympics. Even if you beat a few people you're still slow.

 

true, but wont it be easier and cheeper than the LS1/2

and free?

I could do something ,to the 305, but i havent tried my connections with any LS1, or 350 stuff.

but i dont think i can afford the LS1 swap as a highschool student.

 

save your money and do an ls swap. or any other variant of the 350. you could do an l98 swap for very cheap. 305s are boat anchors

 

I couldn't afford an LS1 swap when I was in high school either, so I left the stock motor alone...for 6 years. Now that I am married and graduating from college I could afford the swap. It is worth the wait. Just save up your money, set a little bit aside every month and before you know if you will be able to do an LS1 swap too.

 

Well i'll look around ,and check some connections first then i'll consider

 

Research is free. Learn and be well informed before you turn the first bolt

 

Very well put Pocket.

 

that sums up life right there.

I'm going to check out my resources first then see what goes from there.. Found a guy today with a TH400 or a 700R4 but i cant remember which he said for 400 bucks.
I'm still thinking of trying to find a 350 block somewhere and try and it.

On any 350, will the LS1 stuff bolt to it, so i'll have FI, and can use a 4th gen harness and intake?
Cause i can get it vatted, and most of the work done for cheep and in-town.

I'm new to chevy, so please forgive me.

 

Nothing from a small block chevy (350, 305, etc) will work on an LS1. The term "350" and "LS1" should never even be used in the same sentence. They are as different as night and day. An LS1 is a 346 by the way.

 

alright, got it... Now.. hmm is it worth it to try and put a 350 in it...

 

Yea, especially if the original motor is a 2.8L

If you can't swing an LSX swap, the next best thing would be a nicely built 350 or 383 (in my opinion).

 

I wouldnt attempt a swap in HS unless youve got a 2nd car and a pile of money. Problems will come up and LS parts are expensive

For the cost of a dropout you can usually pick up a decent V8 car

LS swaps are not for the faint of heart

 

Yea I was going to mention that too. Have you thought about just selling the car and getting an already-equipped 350 car for right now? They're pretty plentiful.

 

dont let the ls powered third gens scare you either. there are planty of old style 350 cars that can catch and tear them up. ask me how i know. i have built both

 

well i'm kinda considering the buying and selling of this car...

new keys, freshen the interior a little and sell it.. try and find a 305 car. we havent bought this one yet, so we really dont have to get it...

 

I honestly wouldn't buy it if I were you. You will find yourself having a hard time selling it with that 2.8L. I know myself, along with most others here, wouldn't even consider buying a 2.8L car. You might find yourself upside down in the thing if you try to flip it for profit.

 

Yeah, and now my grandma who owns my DD is going to make me park it, if i buy the camaro..... guess its no camaro for me

 

Given no budget limits I'd rather have an LS2 than an LS1. The LS2 has a flatter torque curve and makes more power in stock form. That being said there might be some challenges going ahead with an LS2 instead of an LS1 given differences in wiring etc.

 

wiring is your only major difference. But wiring is wiring, there are write ups that are easy to follow so it really wouldnt be much harder. I would have put an LS2 in my rx7 if i could have got one for close to what I got my LS1 for.

 

well i neded up with the camaro anyway, she didnt know it was 300 bucks.. but anyway, i've hooked up TZ28 i think is his name on here with the LS2.. he's gonna get it...

 

Wiring differences are minute at best. Itll take longer to retune the PCM to the 58x OS than to move the connectors
