**98maro** · 07-12-2010, 01:35 AM

Hey guys I'm just wondering.
I have a 00 ss m6 and I been thinking bout do some work to the motor. Ls6 heads, cam (small cam, ls6 chain, pushrods lifters ls6 intakesnd all that
But I was thinking bout just to swap a ls2 in there.
Will that work?
Can I use the stock tranny?
Will thT pass the emissions ?
What you guys think should be the best option
Thanks

you can swap a ls2 in no problem..you will need to make sure and buy the conversion harnesses as some sensors are relocated and different . the only thing i would be concerned about is being a 98...our PCMs are a little different. best to ask frost in a pm if there are any issues 98 pcm related to swapping to a Gen IV motor

He said he has a '00 ss. But I'd still ask Frost as I'm thinking the PCM will need setup for the LS2.

You made me look twice too

**98maro** · 07-12-2010, 07:26 AM

Thanks for the replies

Yes it's for my 00 ss
I take the harnes kit from a car with the ls2 or buy new kit?

The ls2 will fit with the stock motor mounts or I have to make modifications?

I'm I'm Cali. So will that be legal for the smog check?

**Knight** · 07-12-2010, 07:30 AM

You can use the pcm you have in the car now - you just need it retuned so it knows it's running a ls2 instead of a ls1. As for the smog testing - IDK. You may need to consult with a tuner on that one. I dont' know how different the emissions are from a ls1 to a ls2.

**98maro** · 07-12-2010, 07:34 AM

I'm gonna contact frost and see what he says
I'll be doin the smog check this week I will ask
If it pass the emissions with ls2 I will defenetly get that

Wat could be the best. Ls2 or ls6?
They have almost the same hp

**shady milkman** · 07-12-2010, 07:39 AM

emissions shouldnt be a issue as the ls2 is a production engine..and that mostly depends on your exhaust. there a kits available to buy. for simplicities sake just buy the kit. speartech sells them i am pretty sure. the motor mounts like normal.

the ls2 is a better platform in terms of a building platform. as it can be made into a 414ci and is a GenIV. where as the ls6 is a gen III and can only be make into a 383..if you dont plan on modding at all ..a ls6 would be good as it is cheaper and a driect bolt in basically.

the ls2 is hands down better if you want to mod it at all. there is no replacement for displacement

**98maro** · 07-12-2010, 07:46 AM

How much the kit goes for?

I like the ls6 cuz it's the heart from the zo6 or ctsv
And I knw it has some power

Ls2 I like it cuz it's newer
I will do some mods to the motor. Probably ported heads and a cam. Not to big of a cam
And I will get some LT with high flows

So what souls be the best one for that?
Ls6 heads is a good upgrade for ls2?

omg the ls2..no question..i believe the kits range from 300-600

**98maro** · 07-12-2010, 07:53 AM

Shit kinda pricey lol

On the ls2 just portin out the heads is a good upgrade or ls6 heads flow better?

you should do a little research. the 243s are on both the ls2 and the ls6. the difference being that the ls6 243s have the light weight valves. besides that the casting is the same.

**98maro** · 07-12-2010, 10:43 AM

I knew they were bolt ons on ls1 too
But I didn't knw they were the same as the ls6
