It is not big enough. Best you could do is a 3800 swap.

A l67 3800 swap would be sweet. H/C with a big blower...or a turbo....

That would be a ton of work, but I do believe a 3800 would fit in there, not sure the blower could clear the hood, but that is part of the making it fit process.

The LS4 barely fits in our cars and the W Body is a pretty large car.

Read up.

Also, might want to try for an L32, the newer version of the L67.

3.6 <> 3.9... Also the 3.6 in the G6 is not the DI motor, at least I don't think it is.

dude for the money and time youd spend trying to do wierd engine swaps you might as well go get yourself a custom turbo setup and tons of head and exhaust work. The motors in the G6s are running close to what my blown L32 is stock for stock.

There so much more potential for the 3800 than either the 3.6 or 3.9 that I wouldn't even begin to consider using the 60* 3.6/3.9 if I was going to do said swap. There are basically no mods for these later 60* engines. There is a massive amount of things available for the 3800: tuning, cams, intercoolers, turbo kits, etc. While a lot of the people on the forum are jerks, there is a lot of good information over on clubgp.com although it might take some digging to find it. There's numerous people making over 300 WHP, with a decent number of turbo cars making over 450.

I had a G6, used to be an admin on G6performance.com....

Great car in a way, but typical GM interior. I didn't last long in it. The 3.5 left something to be desired and the auto stick was pointless. I am sure the GTP is different but the 3.5 is blah. There are much better choices than that V6. I bought mine because I got a steal of a deal and I still got rid of it early and bought the GXP.

And yeah the 3800 has way more potential than these newer motors.

I wouldn't buy a car looking to swap the motor though, sounds like you should just buy a different car?

Putting an LS4 in a G6 is probably just a matter of time, $$$ and extensive fabrication. I think would be a very cool swap.

The LS4 has already been swapped into several Fieros and several other V8's have been swapped into FWD cavaliers/corsicas. Hell, if a guy can put a N* transverse in a MR2...

3800 would be the best bet. you can find the 3800 in tons of cars to fairly easy.
