GA vs. G8....trade or stay?

[cardude007617]

so just a way of getting the customer to spend more money for differences to a car thats not really worth it?
like 400 dollar tint?

[SC/T02]

Or a mid range between the GT and The GXP edition giving a 30HP advantage over a GT along with poly bushings and a stiffer ride. Plus numbered, PHS documented, custom floor mats, embossed headrests, dash and engine plaque etc. I felt it was worth the extra bucks with all the rebates going on I got it for about $300 less then the GT. If you were a collector you would understand too. I have 7 cars that I toy around with now and I totally understand if you don't get where I am coming from. The way I see it, this is about as close as anyone could get to a 4 door Vette for under 40K.

She rocks the nearly stock 361 HP plus tune and CAI. I had 385+ all the goodies pushing 503 RWHP now and still get 24MPG Highway with cruise set.

Orange best pass 13.22
Blue best run 11.84 traction limited (best 60 foot 1.88 should be 1.4)

No brainer! power, space, style, warranty you can't pass up on this car while there are still a few out and about. Don't get me wrong, I loved my GA and put a ton of money into it. Sold most of the parts and was given $9500 on trade in for an 02 which I could not pass up. They sold it on their lot in 2 days for $13,000 but it was a quick sale for me. Plus I had over $6000 in rebates, and $1500 in GM points to put towards it which GM was matching so the second G8 I had almost $19000 off which helped offset the $39,000 price tag.

You should of went with a Stryker Blue Metallic G8 GXP to collect.




So, what makes your "GTX" have 30 more hp at the crank ?
& what did you do to get to 503 RWHP ?

[SC/T02]

I hear ya Mike. Still only 2 Blue GTX's 56 GXP's. Still a rare color either way. I thought about the GXP but the wife said the MPG in town was too poor to deal with. The GTX runs different exhaust manifolds with a larger collector. It is also tuned differently.

The car stock ran a Mustang dyno at 369RWHP so I think it was factory under rated. Now the big goods are the Yella Terra 1.85 Rockers, line shift kit, 3600 stall, Roto Fab CAI, HSKR kit, SLP 25% underdrive, Stage II ported intake and TB, DOD delete cam, Kook's Full length headers with SLP muffler delete, cat back and a 2.5" x pipe with 2.5" 304SS system. Now I need to get the tune right and get a set of slicks on the back. I have other goodies that help like the trailing arms. Switched from the DT headers because I was getting an exhaust leak. I think with the right custom tune and I should be closer to 550 RWHP but that will come in the spring.

It's not a collector because it is fake. There is no such thing as a G8 GTX. It's about as real as me calling my GTO a 2006 GTO JBACCW and making a fake certificate with its VIN#, etc. etc. In addition, the cars resale value is still low and it will never be worth anything in the future. It's a 4door Pontiac that never sold well until they had cash for clunkers and/or ridiculous rebates.

If you enjoy the car, that is all that matters. But to claim it is more than what it is to the general population is just incorrect. If you were to trade the car in today you'd still get $16-18k tops for it.

Oh yeah...and all that "extra GTX equipment" and the car still has the cheapo, base level wheels modeled after the GTO flower power design.

I'm having a really hard time believing that with those mods and a tune, with no forced induction, you'll be adding almost 200hp to that engine....

[[ChaosweaveR]]

Fake GTX is fake. I will say, I love that color. But @ base model wheels on a GT

[SC/T02]

^ Hey Bobbi, the car is worth it to me. Like I said before, got it for less then a GT. There are 3 people on the Grrrr8 forums with the GTX out of the 130 made. They have numbered cars as well. All GTX were done for strength and auto cross structure, none have 19" wheels due to weight and rotational mass, none have a sun roof due to flex. They do have everything else inclding features not found on the GXP or GT.

Joe, hit up the forums, G8board and see what you see. MANY guys are into the 500 HP club without really doing internals. These L76 engines take mods very well unlike the LA1. A full exhaust, not custom, straight out the box from the headers back is good for 44-58 RWHP depending on tube size and brand. Long tube headers are alone are about 35RWHP. As far as a tune, even an out of the box cookie cutter Superchips Cortex tune is good for almost 20 RWHP, The cam and rockers were about 40RWHP, CAI 17RWHP. Getting the right tune for the cam since I removed DOD, CAI and the rest of the mods would easily bring me up closer to the 550 mark.

Awesome, so there are 3 more, including the other 130 suckers with a fake, worthless car.

More you talk, more you show how ignorant youa re about the car and autos in general. Particularly about wheels. Your wheels are in no focking way more beneficial for handling/autoctross than a larger diameter set with a thinner, harder sidewall tire. This is Handling 101. You failed miserably with your reply.

And I agree with Joe...regardless what you want to attempt to say, no way these cars are in the 500+ horsepower range with those mods. Supercharged, LS2 GTO's with headers and tunes are just making that power. My advice would be to stay on the G8 board you are an admin/mod of and live in your fantasy world of bench racing.

[SC/T02]

^sounds a little like Penis envy Bobbi! Wish you could get out from under the worthless Holden made GTO and step up to an adult Holden G8 that can produce the power. Not sure from a 40 to 45 sidewall when you drop all the extra weight makes sense. A TVS 2300 Sc alone on a G8 puts over 500 HP down with NOTHING else done! Again the L76 takes mods very well. Good luck being a bully on the kids site where you feel socially accepted as the last place that I am sure made you feel that way was your girl scout troops.

I thought this thread was about helping someone decide on getting a G8 or keeping an out out of warranty, dying car? The G8 is worth every penny if you can afford it which many people on here can't so they are reduced to bashing or BS flag raising. It does not take away from the fact that you can own Pontiac's last real sports car. Maybe one of GM's last RWD cars at that. The features will blow your mind compared to the GA. I loved my GA but it is worth the trade up if you can do it.

Good luck with your decision. Let me know what you end up doing.

I have been on that forum, and I have seen the mods people do. And you are wrong. An APS twin turbo G8 GT will make 550hp at the wheels, so if you think your GT with an "X" sticker and a few bolt ons will make that, you've drank too much kool-aid.
I don't doubt that the engine responds to mods well, but with the numbers you're using, it would imply that the engineers put the most inefficient powertrain in the car imaginable, which just isn't true. With your reasoning, a F/I G8 would make ridiculous power, in the 650 to 750 range... and I don't see that happening with out extensive mods.

I just sold a 600 flywheel horsepower RX7 for as much as your car is worth, and would not only walk your car at the 1/4 mile but also in the curves. I drive a slightly modified '06 GTO as a daily driver, a car that can hang with your fake GTX. My wife drives a slightly modified TBSS. Just what the fock am I envious about of you? Because you have a 2 year manufactured car, with a fake nameplate from an overpriced worthless car modifier??

Do you really think I couldn't have bought a brand new GXP if I was so "envious."?? Or go out and buy a used one this afternoon? Or maybe even buy a used GT model this afternoon, supercharge it, and do a full suspension?? There is a reason why....it's not worth it and its boring. The G8 is a good car.......for one who wants a daily driver 4 door sedan V8...period.

When you have a C6 Z06, GTR, Porsche GT3, etc., let me know and then maybe I'll have a bit of envy. But considering I'll be in that arena sometime in the near future you better hurry if you want me to be envious of you.

What gear did they run it on the dyno ?
We don't have a 1:1 gear.
Closest is 4th a 1:1.15.

That 369 RWHP dyno seems extreme high.
Some G8 GXP (415 hp at the crank) LS3 are dyno'ing around that range.

Actually, I moved up here at the first of the year from Winter Springs FL which is near Oviedo or about 30 minutes from Daytona Beach and 20 minutes from Orlando. The site asked me to continue on as a moderator even though I moved. I posted about my car, and nothing that I say on there was any different then what I told you guys...

I plan to take my car back to Livernois in NY where they can Dyno the car again come spring time. So peace be with you and may God keep you as I am sure no one else wants to.

Comments like this really aren't that witty, funny, or hurtful. In fact, combined with your vehicle knowledge in this thread, they are pretty focking stupid sounding. If I was a hardcore religious person, I may even find them offensive and mocking. Lucky for you I am not though..........and you just make me laugh more at you

, the people on that forum are morons. Someone said something about "running an LS4" with DOD. I almost laughed out loud the the OP in that thread, where he claims a CAI will add 20-25 hp TO THE WHEELS, and a Superchips "tune" will add 30hp. Get real.

LS4 does have DOD which makes me laugh that you thought that was funny.

Generation IV 5.3L LS4 V8 Overview

The 5.3L LS4 shares the basic architecture of the 6.0L LS2. This includes an all aluminum block, six-bolt main bearing caps, deep-skirt cylinders, and a structural oil pan. It has the 243 casting LS6 heads with LS1 valve springs, which are good for 6200-6300 rpms.

Engineers had to mount this engine sideways so some changes were made. The crankshaft is shorten by 13 mm overall, 3 mm at the flywheel and 10 mm at the accessory drive. This was done to accommodate a more compact accessory drive. Instead of a 2 belt system there is only 1 long serpentine belt, even with this to save space there is only about 2 inches between the crankshaft pulley and the passenger side wheel well. The water pump is mounted off center with elongated passages to connect to the block (see picture). Also a rear facing intake manifold was designed. To ensure proper oiling during high-g cornering the oil pan has special baffles built in. Since Displacement on Demand uses oil for activation an oil pump with 31% more flow than previous LS2 type oil pumps is used.

Displacement: 325ci (5328cc)
Compression Ratio: 10:1 (premium fuel is recommended)
Bore x Stroke: 3.78" x 3.622" (96mm x 92mm)
Firing Order: 1-8-7-2-6-5-4-3
Horsepower: 303 hp @ 5600 rpm
Torque: 323 lb-ft @ 4400 rpm
Fuel Cut-off: 6100 rpm
- 258mm, RI 15 Torque Converter
- Enhanced Heavy Duty 3.29 Final Drive
- 2.93 Effective Final Drive
- Transmission case for transmission mounted starter
- Net-formed Input Sun Gear
- Ceramic bead Peened Final Drive Sun Gear
- Input/Reaction Carrier Assembly
- Contour Hardened ReactionInternal Gear
- Input Carrier & Gear Asm. with lube grooves
- Shot-peened, Black-oxided Input Carrier Pinions
- Shot-peened Reaction Carrier Pinions
- Shot-peened Final Drive Sun shaft
- Upgraded Drive sprocket Thrust washers (new for high speed capability)


Just for you Joe. maybe you should read up...
Displacement on Demand (DoD) General Information

The original name was Displacement on Demand (DoD). For the start of the 2006 model year GM renamed it Active Fuel Management (AFM).

During light load conditions while in 3rd or 4th gear the ECM will shut down cylinders 1, 4, 6, and 7 to put the engine in V4 mode. The engine will not enter V4 mode while cranking, idleing, or heavy acceleration. To shut down the cylinders the intake and exhaust valves stay closed and the fuel injectors stop feeding gas. The ECM times the shutdown so that each deactivated cylinder keeps the exhaust charge from the previous combustion cycle. This pressure on the pistons keeps them from rocking around in the cylinder causing vibration and oil consumption. Complete cylinder deactivation is accomplished in about 250 milliseconds.

The engine components involved in cylinder deactivation are the valve lifter oil manifold (VLOM) and special valve lifters. The VLOM consists of 4 solenoids that control oil flow to 8 valve lifters. Each solenoid goes with a certain cylinder and its 2 valve lifters.

When DoD is commanded on by the ECM the 4 solenoids energize and allow oil to flow to the valve lifters. The special valve lifters are made of an inner lifter and outer lifter with a spring loaded locking pin holding them together. When the oil gets to the lifters the pin is pushed out of place and the inner and outer part of the lifter are allowed to move seperately. The camshaft is still pushing on the outer part of the lifter, but the inner part of the lifter is no longer pushing up on the pushrod. This keeps the intake and exhaust valve shut permanently until the ECM commands DoD off. At this point the solenoids stop oil flow to the lifters and the spring loaded lifter pins lock back into place, causing the lifters to return to normal operation.
