There's no stickies for this section.

I just have some basic questions on GTOs. Probably just pointing me in the direction of a link or something would suffice. I'm looking for displacement, intake, cam and head, weight, suspension, wheel/tires info for factory GTOs. Also, what exactly is DOD? Did it come on goats?

2004 was the LS1, 05-06 are the LS2, google it and you can get all the specs.

Weight is somewhere between 3750-3800.

DOD = displacement on demand, and nope, never came on the GTO.

Displacement for the 04 is 5.7 liter and the 05/06 is 6.0 liter. The 04 is a LS6 intake. The 05/06 throttle bottle is drive by wire. The 04 uses casting # 241 heads while the 05/06 uses casting # 243.

LS1 = 346 ci
LS2 = 364 ci

The LS1 uses normal 241 casting heads and a relatively tiny cam. The LS2 uses 243 casting heads (factory LS6 heads, better flow) and a slightly larger cam.

Before I lightened it up a little, mine weighed in at 3690 pounds without driver and with about a third of a tank of fuel.

wheels were either standard 17x8 with 245/45/17 BFGs or optional 18x8s with softer 235/40/18 bridgestones.

they have some suspension issues. once that's cured you're in good shape

Is there something about the LS2 consuming oil? Ive heard something about that a couple times, I dont know how common that is.

flyin red TA

About as common as oil consumption on an LS1.

DeepBlueZ

there were a small handful of LS2s that suffered catastrophic failure from A LOT of oil consumption. However, the overwhelming majority either don't use any, or use a little here and there, but are within spec. (similar to LS1s)

My buddy weighed his 06 A4 the other day... 3790 with him in the car!

'04 LS1 is the same as the '01-02 F-Body, right down to the cam.
'05-'06 LS2 is basically a '01 LS6 but with a different intake and bigger displacement.

My '04 weighed in at 3760(without me) when it was stock. Nothing taken out of it and a little less than a 1/2 tank of gas.

No, the oil consumption issue was more pronounced with LS2's.

DeepBlueZ

mine's about 3750 with me in it now...(still heavy as hell, but better than it was )

00SS!

So what did you do/take out or whatever?

Here are the 04 specs:

http://konrademrich.com/cars/gto/gtospecs2.htm tire size is wrong on this one.

Nothing drastic...

the car was 3690 when stock, (no driver, 1/3 tank).

- pulled y-brace (saves 13 pounds)
- lightweight HSV skidplate (saves 12 pounds)
- Boyd F22 wheels (saves 8 pounds at each corner)
- pulled jack/spare/chocks (saves 30-35 pounds, i didn't weight that stuff exactly)
- Exhaust mods (longtubes in place of stock manifolds, resonator replaced with X-pipe, magnaflow muffs which were NOTICEABLY lighter than the stockers, conservatively estimated at 10-15 pounds total savings for these.

overall total = savings of 97-107 pounds or so.

I rounded it out and called it 3600 even with no driver and same fuel level. I myself am the best weight reduction as I'm only 150 pounds.

I'll double check when I can get a chance to get the car back over to the scale I weighed it on when it was stock, but the above math is pretty reasonable.

anybody have a stock dyno sheet

Rpms HP Tq
2500 x y
2600 x y
2700 and so on?? Somethign I can paste into excel??

thanks,
