My On3 Experience
Just wanted to give a little feedback on my experience with my on3 performance single turbo kit. I have some pictures but I kinda rushed it together over a few days, and didn't really take a bunch, but this is just more of my opinions of the kit.
I purchased the kit about 4/5 months ago for my 07c Single cab Sierra. To start, I've never done a turbo install before, and really never messed with FI before this. The truck was a 4.8, that I had installed a 220r cam in, circle d 3k stall, and 4.10 gears, which put down 302/288. I wanted more, and decided I would go FI, after some research, I decided I would use the on3 kit, due to its price really. I emailed them a few times, and pulled the trigger. After about 4 days all the parts arrived to me here in CA. Packaged nicely and all in good order. I inspected all the parts and everything looked nice. No damages, nice welds and bends, to me, everything seemed to be worth the money spent. In reality I felt I got more then what I paid for really. I was very impressed.
The next weekend I started the install. I am no professional mechanic, nor am I anything of a fabricator. I have basic hand tools, no welders or anything. Just a plain old garage with a few jack stand and small tool box.
The install took me about 3 days, and went pretty smooth. Everything lined up nicely, and bolted together well. I struggled getting the intercooler piping together a bit though, but after glancing over the included instructions I got it together. The crossover took a little bit of tweaking to get aligned with both sides. I bolted the driver side up first, which made the passenger side V-Band hard to connect, but after loosening up the driver side, it fell into place. Bolting the turbo to the log was rough, I feel like it would have been easier to do this off the truck, and drop it in as one piece. The rest of the exhaust was simple to put together with the band clamps.
Sunday evening I fired it all up, to my surprise I had no noticeable leaks! I wrapped it all up and took it to the tuner that Thursday. I couldn't find a truck and trailer, so I drove it un-tuned about 60 miles which was nerve racking. Once there it took the tuner about 2.5hrs to tune it, but unfortunately the supplied waste gate wasn't opening correctly cause me to spike at 13lbs, so the tuning was cut short. But at 13psi it did make 522/534, and was shut down at 5K rpms. I drove the truck home and messed around with some part throttle pulls. Truck felt awesome, the power is incredible and I was smiling from ear to ear.
I swapped the on3 WG out for a Tail one, and I was finally making 7psi. Now heres where things went bad. I went out for a couple fun runs with some friends. Well turns out 70mph rolling burnouts on the freeway is frowned upon here in CA, and so are "highly modified" vehicle. I was pulled over, truck was impounded and refereed. After a few thousand in fines, and impound I got the truck back. Sadly, I had to pull everything out, and the kit was sold.
I guess that was more of story time then anything, but all in all, in the short few months I did own the kit, I had very minor issues. With my only big issue being the WG which is to be expected. IMHO I would recommend this kit to anyone. Don't be afraid to run it. Just heat wrap everything, trust me, the heat that it makes it killer lol.
Im glad I didn't listen to all the nay sayers, seems everyone who says don't run the kit, haven't had experience with it. With my first hand experience, I would, and WILL buy from On3 again. Once I wrap up my lq9 swap that is.

Sorry to hear about ur run in with the Law. I dig the rolling burn outs too, until trans decided to go BANG! I also was happy with ON3 kit I have around 3k miles on it so far. Picking up new trans Monday then I hope to run the **** out of it.
