    Looking for a 2004/5/6 GTO. Any insight on getting an ls1 (2004) or ls2? (2005/6) i know the ls2 motors had the issues prone to eating oil but i havent been able to find much on the ls1. Looking for the better base and i do plan on doing head work and big cam.

    Wife's friend has an 06. She drag races it. Fairly stock. She has no complaints.

    Alot of ls1 eat oil between changes. 1-2 quarts depending on the type.

    My 99 z28 m6 pushed 415hp at the ground after the last tune. It would use about 1/2 qt between 2k mile changes.

    Ls2 is what it is. Same dog with bigger holes. Bigger holes means more power per dollar spent.

    And, I remember hearing of alot of suspension/wiring/brake issues in the early models.

    Hmm so sounds like sticking with an 06 would be the way to go, i though it was strange hearing of any issues with any of these motors though they were real solid. Guess we will see!

    Oh they are solid. I don't know of any production models that could handle what I've done to this car

    A lot of people don't know that the LS platform take more oil to fill after a oil change. They should not use enough oil between changes to notice on the stick. If they do the the oil rings, valve seals, or gaskets somewhere are not doing their job. On a long shot the rings themselves are not sealing in the cylinders and letting compression into the pan and blowing oil out.

    I have played with both the LS1 and LS2 and they are nice engines to work with. As for the Goat, the G8 is a lot nicer car. More stable at ummm, higher speeds, good balance in the turns.

    Depending on what you want out of the car will be a large factor in what you need to do.

    I do agree the g8 is a wicked ride and very nice a friend of mine has one but a manual trans is a must no exceptions for me. If it had the t-56, id consider it more

    Zombie, got ya, a gear banger...be still my heart. The T-56 is a easy swap into the G8 as the parts are the same as the GTO. I just finished a T-56 swap into a 85 C 10 and everything was custom due to the age difference, turned out nice and FAST.

    What do you plan on doing with the car? Drag racing? Auto x or just a fun street car? Both engines are very good and can be made to push some good numbers with few mods, the LS2 is pretty much the same engine as the LS1. A heads/cam swap and some minor bolt ons should get you well into the 400+ rwhp realm. If you plan on drag racing and want to to do it with good results, I am going to suggest going auto and a big converter (at least 4000) to go with that cam and heads swap. I dropped a 1/2 second with no other changes than going from a T56 to a 4L60E and Yank 4000. The car would go consistent 1.5 60 foots. And it was fun on the street. That said I do understand that a 6 speed is fun too, but don't be fooled the T56 is not a strong trans. My car was a 2001 Camaro SS. With just the mods I mentioned, plus long tubes and some minor weight reduction the car went 11.4's @ 117 pretty much all the time. It was highly dependent on pulling a good 60 foot though, if the track sucked the car would lose 3-4 tenths pretty easy.

    No no it wouldnt be a race or drag car just my DD haha. Im wondering though if i cam it how big can i go for the heads on that motor without dual springs? Thinking on one around 232/234 or so 112 LSA, open to ideas. And how long would those springs last with a big cam? Of course ill change them out when i do a cam but dont want to spend the cash for new heads with duals ect....

    Drop a dime and call the cam manufacturer, give him the info on the engine and car along with what you want and buy the cam set. It will come with the cam, lifters, valve springs. This way you will know what you need to get it thru the OBD II test for inspections and that the springs will be able to handle the cam. The heads can have some good work done for well under 1K and with a better throttle body and good air system will produce some good numbers. I'm not a big HP fan, I love torque, that is what moves the asphalt, HP sells cars. Then a good exhaust system, sub frame connectors and shocks will help put the Umph to the ground.:D

    Agreed, however I would not run single springs. I always used Patriot Golds that are matched to the cam. As far as passing the OBDII sniffer, HP Tuners software will let you "edit" things so you pass. I had no cat's, long tubes and a very small muffler and I cruised right through emissions. :)

    My Cam is the Futral motorsports fms f14-114 high lift - 232"/234" .646"/.612" 114LSA - with the Manley dual Spring, titanium keepers and rods. http://www.futralmotorsports.com/fms_partsgroup.asp?pf=1&pg=5

    Go double springs always. That way you can raise the redline without fear. Mines at 6900.
