Haven't Posted any pictures but the past two days I got quite a bit of work done. I hope to eventually get a parts lists on here so that anyone searching a build like mine will know what a "bolt on" kit takes to "bolt on". I'm no where near complete, I still got a laundry list of things to do, but I hope to have that hashed out by this week sometime and then off for a tune where we can learn of more fun "bolt on" things. I definitely needed the help of my FSMT friend and his lift tools/expertise to tackle this in a timely manner.
Here's what I've done the past two days:
Felpro MLS head gaskets, ARP head bolts, LS6 springs, ARP manifold bolts, felpro manifold gaskets, NGK TR6 plugs (yes you can put them in with the On3 turbo manifold), On3 70mm turbo kit with WG, BOV, FMIC and all hot cold pipes *even though Chad NEVER answered my requests for pics of cold kits*, Sealed Catch can with check valve, Down pipe and exhaust connected, heater lines extended, oil return/in.
Lessons learned with the On3 kit installation:
1. No instructions/Pictures other than what is here on pt.
2. Front mount brackets need to be rebuilt, unusable. FMIC sits too high.
3. WG is a PITA to connect to the recirculated downpipe, seems to be about 1/2" off, we eventually got it to connect by loosening everything up and prying up on the downpipe from beneath.
4. Downpipe HAS to be cut, no way that thing would work without it, needs to be changed.
5. Yes, You can change plugs on On3 manifold, but you can not use stock length LS wires, they touch, will build custom length with 90* boot and go around manifold.
Once I get it tuned and running then I'll give a pro's and con's I think its still too early to measure.
Whats left for me: Fuel pump (dropped and broke my first one LOL) hot wire kit, coolant reservoir, TruBoost gauge/controller, Build ur own Spark plugs, sd tune, ls9 inj, MAP sensor.
*the pic of the FMIC is incorrect, we had to lower that around 3 inches and make new brackets for mounting.

FYI; Im going to start 'on 3 turbo' install on my late mod 07 this weekend.

haven't been on lately been messing with the cars and boat. recently traded my Z06 for a whippled fifth gen, might post some details about it but for now its "cam only ".
as far as my turbo silverado, i've been daily driving it, already changed the oil twice. Ran into a problem with some oil pressure on the feed line to the turbo, put a oil restricter on it and that fixed my problem. (blue smoke at idle after WOT) I believe I'm just under 3k miles on the kit and no problems other than that one.
My trans is still hanging in there, haven't gotten to take it to the track I imagine it run a 13 something, couple people have been in it and think it run a 12 with a tire.. I doubt it.
I have acquired a 4L80e, but I'm not sure if I will need it. I really don't think I'm going to need any more power with the truck so I may stick with the 4L60e and rebuild it.

Well today I got around to getting my tires mounted on my powder coated Mille Miglia 20's. I still need to locate caps, the ones that came with the wheels don't look appealing to me.
I personally like the look, next step is to hopefully get my hood and front bumper replaced. As long as my trans holds up.
My other pic is of my new Camaro (yes that's the actual car) that I traded my Corvette for.

A little update right now I'm just under 11k miles on my On3 Turbo kit, I believe my wastegate has been messed up for most of the summer, I've been gone quite a bit for vacations and boating etc, but yesterday I got the chance to pull the wastegate off.
Some of the things I noticed was, I wasn't building the boost on normal driving like I use to, maybe 5-6 #'s, on a hard pull I was still able to get the boost up but it really felt like it was taking longer. My MPG has dropped from a 19mpg avg to around 16.8 consistently. I also know that I couldn't even do a burn out so this has been on my mind for a while.
What I found was a wastegate stuck all the way open, the valve inside is completely frozen solid. I've thrown it aside and ordered a 46mm Precision WG, it should be here in the next few days. I also plan to swap out plugs, I haven't checked them since the first few thousand miles but haven't noticed any difference in idle etc. Lastly just go through everything, the turbo is holding up quite well and same with the transmission. In fact I'm still in shock that the stock 4L60e has held up and maybe a stuck open wastegate has helped it?

well i got the 46mm Precision wastegate installed earlier this week. Everything is back together. The fit and finish of the Precision compared to the On3 is very noticeable. The flanges are very nice as well. I once again battled the recirculation pipe coming out of the wastegate into the downpipe, I regret not welding that shut and not dumping to atmosphere but I will deal with that once or if the truck is down for an extended amount of time.
I installed the 2 springs for the 9lbs, if i get too much creep I may go down to 7.5
I haven't gotten the boost up high enough for the controller but I'm hoping it's better with the 46mm.
