So I am in the process of a new build. I finally have the long block fully assembled an sitting in front of the truck. So I figured now would be a good time to start my build thread. Bare with me when I bring you up to the current build. I have an 03 silverado SS awd. It has had a 370 motor in it since 29k miles, it currently has 77k. It had an sts turbo originally and then when the local borough dropped the I/m program. I immediately ordered the pipes from kbracing to make it a front mount. When I did this I also installed a front mount intercooler into the front bumper. I went with a 31x12x3 I/c. I had to cut and box in the frame to make it fit but it works great with the SS bumper. I also upgraded from a 67mm turbo to a mp t-76 turbo when I moved everything. With just diamond pistons(8.8cr), arp rod bolts and head studs I ran consistent 12.25's all day long with 22" tires in full street trim at 12-13psi with meth. Kb sent me a 3.5" downpipe and I put on a full 4" exhaust all the way out to the stock location. Used a mbrp diesel muffler also. So now just this past November I figured it was time for some upgrades. I was thinking new motor, but decided to just do a cam and intake manifold and fuel system upgrade. So I ordered a cam from btr and a edelbrock pro-flo intake for it. When I dropped the oil pan to remove the oil pump this is what I found.

This is all my own fault. I took my time and used a ton of grease and cleaned my drill bit a hundred times. I still got shavings in the oil pan when I drilled my turbo oil return hole. When I saw that, I decided I had better pull the motor as see what the damage was. I had never had a hiccup from this thing. Never lost any oil pressure nothing. Idled at 40-42psi hot. Ended up that the back two cam bearings were well into the copper. I didn't have time to do this motor so I dropped it off at the local machine shop. So they started measuring everything and I had two pistons that were out of specs. 6 pistons had .006 wall clearance, 1 at .0075 an one at .009. So they told me I need new pistons also now. So I decided I would build this thing as much as I could afford. My wife was on board to let me do this. Considering we had just had twin girls a few months before this all started, she has been awesome. So here is my build list. I'm sure I will forgot some things. Start with the long block -Wiesco 15cc dished pistons (cr should be 9.65 if I figured it right) -Scat h-beam rods w/arp 2000bolts -Eagle 4" crank -New ls7 lifters -New lifter trays -New melling hi pressure/hi vol. pump -New timing set -Btr spec cam should be half mild 230 238 608 586 117+5 -Tfs 225 heads 70cc-worked over by btr -Btr double springs -Btr trunion upgrade -gmpp 4"stroke windage tray -arp main studs -arp head studs(already had) -ls9 head gaskets -I had my valve covers, front cover, valley plate and my truck accessory drive bracket powder coated black -I also tried something else. Piston oil sprayers. We only have 90 octane in Alaska for fuel at the pumps. I figured this might help out a little bit. And keep the heat down from higher boost levels. I'm pretty excited about these. Attachment 70451 Here is the piston sprayers being installed Everything else -4l80 transmission -build kit from patc for 4l80 -precision industries 3200 stall(had a 3k before from them) -05 fuel tank -2 walbro 400 pumps -edelbrock pro-flow intake -90mm ls2 silver blade throttle body -Id1000 injectors -Aeromotive fuel regulator -all the fuel lines and fittings to run a new 8an supply and use the stock supply as return -racetronix dual pump wiring harness -New kbracing hot pipes for s480 in t4 form w/4" downpipe, I had the pipes ceramic coated in a new titainium coating, probably still going to wrap them too -Bw s480 t4 with turbo blanket from forced inductions -jgs 50mm wastegate I'm sure I am missing things. I will keep adding to this as I remember. Sorry for the pics but they are all on my phone. I am just getting ready to start putting this all together. The long block is sitting here finished. The tranny is finish and built. I need to change the exhaust around a little bit before I put the tranny in. I have some of the small stuff done and ready to go. Some things I still have to figure out is some driveshaft loops, driveshafts (going to use a stock 3/4 ton if it fits, I don't think the rear will though). I will be running methanol on this setup as I did on the old setup also. I have always ran pure meth also. I haven't figured out if I am going to run 2 or 3 nozzles yet. I get all the meth I can use for free so that is nice. Maybe I should run straight alcohol. Haha! My goals for this thing was originally to try to put 800hp to the ground. I am kinda doubting that this will do this. But we will see. I have an awd dyno about 2 miles from my house.

 

Nice build.... Best of luck to you.

 

Looks fun! Curious why did you didnt go with the BTR lifters instad of LS7s? Also I wouldve gone lower on the compression, but thats just me.

 

Btr talked me out of the slr lifters. He said genuine ls7's would be just fine. So I went off what he said.

I also think I should have gone a little lower on the compression. My plan is to get this thing running and drive it the rest of the summer, and then this winter pull the heads. I don't think these head will flow enough for this setup. I have another motor that I am planning on putting these on later. And when I do this I will go to a bigger chamber head and hopefully get my compression down to around 8.8-9.0. If I hadn't ran out of money for the time being I would have bought some 235's or 245's. Since I only have 4 months of summer and 8 months of winter I had to get this thing running.

 

Those heads will be good for 1000rwhp in high boost. This is going to be a cool build and I can't wait to see it running. You have most everything ready to go so this build should go fast. You need a photobucket account btw.

 

exciting! snowball effect for sure from a simple cam, intake and fuel system upgrade......you wanna finish my truck too?

 

Thanks! I'm pretty stoked to get this thing done. Well. I will wait and see how this setup performs. I was a little worried about the compression vs. the high boost it will take to make 800hp with awd. But we will see what it takes. Maybe it will do it at 15psi instead of 20?

I will work on the photobucket thing tonight. And fix the pictures.

 

Just jump in line. Lol. Once my SS is done I get to start on the 408 in the s-10. Drop your truck off. I'll get on it after that. You just might not get to drive it for a while! Haha

 

Just wondering what some of you guys have used for inline filters. I was just going to put a 130gph 40micron inline filter on. Do you guys think this will flow enough with the dual 400's?

Another thing. On my old turbo feed line I had an 4an supply. Is this enough line for my new s480? I'm sure my #10 return will be fine.

Thought I would throw this up to look at. I just set the manifold up to mock it up.




I just had surgery on my ankle today. So next week the install begins. I have so much to do. Should be fun.

 

I think my tsp 408 with my FLT 4l80e is going to beat your northern industrial, tranny Tom combo. I hope your 80e stays in fourth.
