Don't happen to have the part # of the u joint you used, do you?

 

My driveshaft builder ordered spicer solid u joints for a 2500. Not sure what the part numbers are though.

 

Just ordered more parts. I haven't gotten a better tune yet (still driving around with this mail order tune), so I decided to buy a wet kit for the sierra. I went through nitrous outlet and ordered the works. I got a plate kit for my 78mm throttlebody, complete with switch pannel (that fits where the 4x4 switches would normally be), purge kit, bottle heater and bracket, progressive switch, 15lb bottle, window switch, timing retard module, etc. All in all cost me about $1700. I should hopefully be taking delivery mid week. I also ordered myself some wheels and tires. I chose ion alloy style 171 wheels, which look similar to outlaws. They are available in 6 and 8 lug, so my fronts and rears will match. I went 16x8 up front and 16x10 in the rear. I will be running mt et street 28x11.5 in the rear. Ill update this thread with the progress. Its work I can hopefully get done this comming weekend, so I can finally get the truck tuned properly.

 

Here are some pics of the new wheels and tires... and look what came in the mail today

 

Nice Im doing a 2005 sierra fleet side a lot like your truck. I want to try to use the ls3 I already have though. Just keep running into road blocks with the stupid DBW.

 

any dyno results yet?

 

I have to set my gears up again because of a vibration over 85mph, install the nitrous, then I will dyno tune. I'll be sure to post installation pics and dyno results.

 

Some progress on the n20 install. I have only had limited time lately with work and the holidays, but here's what I have done now. Maybe not the cleanest install of all time, but I am happy with it.

 

Very nice build. Looking forward to dyno numbers & track times.

 

Looking bad ***! Hope to see some video of this in action
