Cobalt SS was 260hp and could be had with a limited slip diff.
For V8 goodness, the 300hp LS4 engine was in the Monte Carlo SS and Impala SS. a 6-speed manual from the Pontiac G6 can be added with some work.

This.

I'll second that. A retune will give you another 50 BHP and if you don't mind changing turbos (and in higher output stages, rods and pistons) you can pump out high 400s with these rugged motors.
How much are you looking for?
I was under the impression that the OP was looking for a beefy transmission, and already had an engine in mind.

Thats what you might have thought but it isnt entirely true. If I start with the high output stocker then as I add power we can get to what I want. Now I guess I have to add a qualifier. We have 2 or 3 good choices here but which one of those has the best hop up potential, including the option of a stand alone engine management system, affordable parts, bigger turbos.................you get the idea. This is not a drag car project. This is for very high speed highway running and limited track use. By track use I mean tracks , not autocross. Think alms style but............we will seee about the butts.
4G63T out of a 91-92 DSM (strongest combo of engine and trans), cable shifted for ease of adapting, a real 200 horse out of the box, 250 with a boost controller and open exhaust, and the sky is the limit, only controlling aspect is the depth of your pockets.
Easy to package but somewhat tall and wide with stock intake manifold. Cam gears are big and there is no way getting around that. Iron block is somewhat heavy. Another sticking point is the water neck faces the transmission, not a huge deal in a transverse app but somewhat of a pain in a longitudinal application.
FWD DSMs run 8 second quartermiles, not too many other cars listed can do to that.
07/08 TL-S with the 6spd. They were 286hp/252 tq with an LSD.

Wierd. It's been some years since I was into neons, but there were LOADS of stock SRT-4's running 10's on slicks. Grab the motor from a turbo PT (plentiful and cheap) and put the Neon intake on it.
Barring any abuse, they were pretty strong. 300whp is possible on stock turbo (BTDT), and I ran it through the much weaker DOHC 2.0 Neon trans without issue.
I'll have to side with the 4G63 or (gack) H22 route. The local guys who drag race front-drive MitsuMills have no transmission problems. 2.4l Galant transmissions seem to be their tool of choice.
I seem to recall that the 700+hp drag Prelude-engined cars justr ran stock transmissions with no issues.

And those 2 or 3 choices are what exactly? Without that information we can't help you decide which one fits the need. Unless you enjoy the random gesticulation of the board members here :)
Well- I can say, a modified DISI block on a bigass turbo with a bone stock ms3 trans, clutch and axles is making 750whp right now. Though, I have to like the DSM choice. I know E36 M3 about the transes in the FWD ones ( I was always an AWD owner) but there is no easier path to giant power, IMO.

I do enjoy the random testiculation that you speak of . keep the ideas coming.

This gets my blood worked up. I dont imagine 4-5 hundred na horsepower is out of the question. With daily driver reliability.
Were GM 3800SC motors available bolted to standard transmissions?
In reply to 4cylndrfury:
No but they share the GM 60 degree bell housing pattern and there are a number of transmissions that we bolt to that, including the F40 that came in the G6 GTP that will run you a cool $400 new.
How hard are the ls4 engines to find. Other than the bellhousing is it structurally identical to all the other ls series of engines.
Wiki sez:
Applications:
2006–2009 Chevrolet Impala SS
2006–2007 Chevrolet Monte Carlo SS
2005–2008 Pontiac Grand Prix GXP
2008–2009 Buick LaCrosse Super

along this line, the 3000gt/stealth TT AWD transmission came with 300 or 320 stock rated and at increased hp they usually blow transfer cases before the transmissions from awd drag launches and came in 5 or 6 speed flavor. I will say that the last time i paid attention, rebuild parts had been discontinued. Also, internally, the FWD NA 3S 5spd is the same as the DSM box above and they're all over.
