Oh My God, I Love The Ls2

i was just looking up some info on the ls2 engine, researching a cam. hold sh!t, gm high tech put a livernoise stage on cam in and had it on the engine dyno, with stock gm tune it kicked out 90hp. thats ridiculous. i think im putting in a cam before anything else. the headers will still go on but they are gonna wait. i think its gonna go : install what i have now e-fans, tune, then cam it then get the trans ready real quick before it explodes like every other gm product i've owned has done. then headers i think I've decided to get a nice set of headers with high flow cats, because emissions testing is coming here in the next two years or so they say. and then i wont feel guilty about dumping junk into the environment.

Yeah dude, they are pretty stout motors--and can easily be modded to produce WAY more power than what they come with from the factory... Either it be the TBSS, GTO, G8, etc. the LS2 is one bad bitch!

awesome news to hear man glad i decided to go TBSS for my new family truckster... :) granted i dont have on yet but i will before the baby gets here in Sept.

i heard that the g8 wasn't getting the ls2. everything i have read says aluminum 6 liter but nothing has said ls2. maybe im just picking but i've just never seen any article say ls2. the ls2 isn't offered with the cylinder deactivation stuff.

oh and i have stayed up till 2am researching cams and have decided on the tr220. i thought about the 224 but decided to go am little less because it is still the family hauler and the hp difference between them is minimal the 220 actually make 10-15 more torque which i feel the heavy suv needs.

I saw a flyer at the GM performance display in Houston this weekend and they listed the LS3 as the engine for the G8. :rock:

Just went to the Pontiac site and they list the 6.0 LS2 as the engine :nutz: Give me the LS3!

I sure love my wifes TBSS. I would buy her a Honda in a second so I could drive the SS everyday.

If it is a LS2 in the GT G8, it is tuned down. The GX? is getting the LS3. I believe the GX? comes out '09.

the ls3 is the same displacement but is a higher compression 6.2. when comparing think lq9 vs. lq4 with the ls3 being the lq9 and the l76 being the lq4. im gonna branch out and say the GT will get the LS2 for one year then switch to a massaged l76(around 403-420 hp) then the GPX will come in a year later with the LS3. im wanting a G8 El Camino!!!

i heard a lpe gt2-3 cam or mti stealth cam are the way to go with the tbss perfect for the weight or the cam adm performance offers

well those cams dont have the duration im looking for, i loved the cam i had in my silvy, the comp 269hr and the tr220 is a little milder even than that so im pretty sure i want the tr220.

my fault i meant l92. my mistake :)

G8 GT's have the L76 in them and are running mid to low thirteens STOCK and one tuned by Vector Motorsports ran 13.1@ 107 with no other mods...

Members are also saying STOCK, NO TUNE they are pretty much even w/ SRT8's. The Aussies (Holden Commodore VE-SS) got the LS2's...

The GXP due out late this year is supposed to get the LS3 and six speed man or auto, Manual gets 3.70 rear and the auto gets 3.27 rear....

Can't wait to get one...

L76 is the intake, which you have to have L92 heads, for the L76 to fit. Question is: what is the bore size of the cylinders?

Yeah I know, a cheap copy and paste but I'm lazy...LOL

6.0L V-8 (L76) Application:
G8 GT Type:
6.0L V-8 Displacement (cu in / cc):
364 / 5967 Bore & stroke (in / mm):
3.99 x 3.62 / 101.3 x 92 Block material:
cast aluminum w/ cast-in-place iron bore liners Cylinder head material:
aluminum Valvetrain:
valve-in-head; 2 valves per cylinder; roller lifters Ignition system:
high-energy distributorless ignition; solid state direct-fire ignition w/ coil near plug and integrated ignition Fuel delivery:
returnless, multi-port fuel injection Compression ratio:
10.4:1 Horsepower (hp / kW @ rpm):
362 / 270 @ 5700* Torque (lb-ft / Nm @ rpm):
391 / 530 @ 4400* Recommended fuel:
regular unleaded Maximum engine speed (rpm):
6000

Okay, that compression loss is why it's not 400hp. L92 chambers are bigger than 243's.

And it's tuned to run on regular unleaded...
VMS claims 30+HP and 3MPG increase w/ their tune on 93 octane and that's damn near 400 crank HP...
