How easy (or not) would it be to put an LS2 into a LS1 car?
Discussion
Dont ask me why as its a daft question I know but had this floating around in my mind recently, how universal are these LS engines between the different versions.
For example if you had a CV8 with an LS1 in and simply wanted to fit an LS2 out of a VXR model how easy or difficult would it be to do, whats the actual differences or would it just drop straight in including mounts and ecu etc?
Sames goes for replacing an LS2 with an LS3, easy as above or the same or harder?

My guess is the engines are interchangable but the electrics are not. Ecms, Bcms etc are specific to each model. Anyway, why would you want to when an LS1 can produce more power than an LS2 or LS3 with the correct mods?
I wouldnt want to it was just a daft idea had in my head and it keeps coming back lol
True with the LS1 one but if you modified the LS2 or LS3 then they are a head again.
Main issue is reluctor wheel as mentioned. But there is also some messing around required, but usually extentions and converter cables are cheaply available. You can run a 58x in a 24x with a converter unit, but the ozzies say they are unreliable.
Better to get the engine with the right reluctor.
E40 LS2's are 24x if that helps. Later E38 ones and LS3's are 58x
Just buy a Gen4 engine with a 24x reluctor and it will bolt right in.

I love this argument. An ls1 modded can make more than a 2 or 3? Can it make more than a modded 2 or 3? I can bet a modded 1 with the same output as a stock 3 would be no where near as nice to drive. I'd rather have an unmodded 3 if its all the same as I prefer to see my car on my drive than gathering dust in a workshop.There is simply no replacement for displacement

Reluctor wheels are new to me!!
How do you know which version of the LS2 you have?
So you could simply take an LS3 and drop it into a later E38 LS2 car in theory?

Electrically are easy if you choose the mechanicals right. ie. Reluctor.As for power. There is little argument that the LS2/3 platforms are better bases and will produce power easier than the older LS1/6 units so your suggestion is just plain wrong.
Maybe fundamentally not much different. But more displacement and better heads, and in the case of the LS3 a better intake mean they start off with an advantage over the older LS1 stuff.
Monaro LS2's are 24x I think, while vxr8's are 58x
E40 ECU on LS2 Monaro's and E38 on vxr8's (& LS7 and 2010 Camaro's, basically all the cool cars! Only the rubbish ones with small boots get the E40.)

for so long at this one, that the arguement has been truncated.My take on his arguement is that for less than the cost of a transplant, you could upgrade an LS1 to produce more power than an LS2/3 (though I don't know how true the arguement is).
As to the 'unreliable' or 'unuseable' tags, I don't buy that on an LS1 engine pushing 400bhp at the flywheel.

Of course I'm not suggesting if you have and LS2 or LS3 you should throw it away and buy an LS1, that would be dumb. However, there is no reason a modified LS1 cannot produce as much power as you'll ever need as you well know, especially with FI. I do accept it's more difficult if you plan to stick with NA.
