Thinking of swaping a 402 ls2 into my v.No idea what im doing with the ls6 maybe going in my 3rdgen camaro. How hard would the swap be ?v

Or maybe even an lq9

Its easy, get the lpe 58-24 converter and order the harness for the relocation of knock, map and cam sensor, tune and your done

The lq9 is nice for boosted app but not for na. Stick to the alu block, lighter and better for your car

in a case like this will the original computer work?

Yes but you need to communicate its its language of 24 x crank and 1x cam, the ls2 is 58x crank and 4x cam...

Just curious do ls6 v's use the e67 ecm too?

Your doing what I am doing, except it is a bored and stroked LQ9 block. I would just change out the reluctor wheel, I heard good and bad thing about those converters and its not to hard if your gonna go through the engine and check everything out first, I went with an LS3 top end, it is gonna be NA, dont understand why people say the LQ9s are not good for NA, I understand with the difference in weight, but if your inf or a budget build, it is a great motor. You will need and cam extension harness and knock sensors relocation kit. Or if you fancy enough, it is something you can wire yourself. Also, if you do end up using an LS3 or LS2 top end, the fuel injectors may need adapters, some companies have it to match plugs already but just make sure you look into it. Other than that, it is a simple swap like NAF has said

I've been looking into an LQ9 swap for a DD with 230k+ miles on it and this is what I've come up with so far...

from what I can tell, the LQ9 is a genIII motor and therefore wouldn't require cam and knock sensor relocations or extensions but I don't know this first hand. It would also have the ls6 style reluctor wheel in it wouldn't it?

And if you put ls2 or 3 heads on it, you would have to ditch the ls6 manifold as well as the fuel rail wouldn't you?

Let me know how right or wrong this may be.

Thanks

Ive heard the mounts are different for the lq9 is that true?

Not all LS2s are 58x reluctor. 2005 Vettes, 2006 TBSS, 2005-2006 GTO are 24x, to name a few. Matters where the motor came from.

From what I understand the LQ4 motor is the Gen III while the LQ9 motor is the Gen IV. And yes I have a FAST 102 manifold. The conversion is pretty big witht he LS motors, Pretty much if you go with an LS2 Block or LQ9, you can fit LS6, LS2 and LS3 top end, an LS3 Block can support an LS7 top end. With the cylinder heads you just need to match the ports for the intake manifold. The LS6 fuel fails work on the manifold, just had to use adapters for the injectors.

I havnt heard anything of this, it also depend on the manufacturing of the mounts as well. Every company has its "own" design

Here's what I've seen on the motor mounts...

Here's a little LQ9 Gen III info...

Just to be safe i think im going to go with the ls2 over the lq9

I used revshift motor mounts on a ls3 using the stock mounting brackets and not issues...

The aluminum blocks seem to have all of the motor mount holes whereas the cast iron blocks don't. In other words, any aluminum block should bolt into the V1 but the cast iron blocks will need the plate llinked above.

Just to confirm, the LQ9 should already have the same reluctor wheel as the LS6 as its a GEN III engine.

Yes the lq9 and ls6 are identical internally as gen3 ls series engines...

I just done an LS2 swap in my 05...everything will bolt right on, and use your LS6 intake, if the LS2 is a 24x Crank reluctor you're golden, if it's a 58x you'll need a TRG-002 from Lingenfelter ($250) and you'll either delete the knock sensors and tune them out OR get knock sensor extensions, LS6 sensors are on the Valley cover vs on the side of the block on a LS2
