Thread: LS4 Build, what to buy?

Just clear the codes first did you ever unhook that battery?

I cleared them. But they come back as soon as i try to start it.

Ive double checked that everything is plugged in. And all the wires look good. I also left the battery unhooked for 20+ minutes several times.

I just realized texas speed sent me a 4x timing gear, and i put it on. Im pretty sure thats why it wont start. On the bright side though my throttle body works.

I got the cam gear swapped out with the stock gear.I got everything put back together and the car fired right up. Its late so i only ran it for about a minute, but everything looks good.

TURN DOWN AUDIO!

It will be nice to see how it sounds with the 3" exhaust on there. my neighbors are gonna hate me.

I tried to get a better video to capture the lope of the cam. The audio is a little better, but still kinda choppy.

Yep, preload is set. Once everything was all oiled up it was nice and quiet, no chatter.

Finally after about a year and a half, the Grand Prix was able to get out of the garage. It was just nice enough that I was able to wash it. All I have left to do before I can drive it is install the TEP trans cooler, and get the new 3" exhaust mounted.

looks nice, i'm excited for you.

I got the new wheels and tires put on the car. I went with hankook ventus v12 evo 2's. I put 255/45r18 all the way around. I love the look of the new wheels, and the fitment is perfect.

I Tried to take the car for a quick trip down the road, but couldnt make it out of the driveway thanks to the snow. I managed to get my trans cooler installed as well.

It is the stand alone max2 made by TEP. A little pricey, but it's a really nice kit.

I need one of those on mine, just haven't got to it yet.

I'mma bit late, but uh, this is awesome! Good work.
