I thought I'd share my build with some of you considering the DIY turbo route. I used to have a D-1SC setup with Dynatechs LT's. I sold these items to fund "All" of my parts for the TTbuild. Fortunately, I invested in a Cheap 110v MIG welder a couple of months prior. I will use this for the downpipes, and wastegate plumbing. Everything else will be tacked only. I will have a professional finish it off with a TIG.
For the first few months I aquired needed parts from various vendors. I spent a TON of time searching and pricing out everything so I could keep the costs down. Even with all the extra shipping charges I was able to find some great deals.
The Engine is an LS2 Stroker. 403ci.
Arias Forged Pistons
Eagle H Beam rods
Eagle 4" Crank
CNC Ported 317 heads, patriot gold springs, Harland Sharps
Comp 273HR cam
2 Turbonetics MC66's.
(aka TC) 4" inlet 2.5" outlet $1,760
2 Tial 38 wastegates $450
Flanges SS $24
2 Escalade manifolds (New) $60
I've had many PM's about these manifolds. So here's some info on them: These types can be found on most GM trucks and SUV's. These particular units are version 2003+ which do NOT have the EGR port on them. Prior to 2003, these manifolds come EGR equipped. They can be found on Ebay with a simple search for "GM exhaust manifold, 5.3 manifold or 6.0 manifold".
Cusom Flanges 1/2" Mild $45
GM exhaust gaskets $29
2.5" and 3" 304 Stainless-
Piping for hotside. $220!
T4 Flanges in SS $38
V band flanges $70
Exhaust wrap $50
Misc shit like nuts, bolts,
Tubing and Tools $200
Built TH400 FMVB with Ultrabell $400 (Local)
Used but good Yank 3600 for Th400/Ls $525
Edlebrock Victor Jr with fuel rails $300 (Thanks Nmbr1GMfan)
Solid Engine mounts $69.99
Griffen Radiator $270
Derale Fans $200
Still Need to buy:
2 Filters for turbos: $100
Intercooler $235 (Ebay for now)
Al piping, couplers and clamps. $110
The quality is actually pertty good
on these. 2mm thick, reinforced
silicone and T Bolt clamps.
HP Tuners. Someone stole this from me. $650
Someone to finish welding. $300?
This is all I can think of at the moment and I will update this as other costs come to mind.
The original plan was to run Twin 67mm units in a small 3" x 2" type E compressor cover. This would have opended up more room for possibilities. I was going to mount them facing eachother in the front of the engine bay, thus the reason I remounted my AC Condensor and Radiator at a tilt. But soon after I started the build, I found out that this would have required much more Talent and creativity to pull off in my garage.
I chose the GM manifolds because I did'nt want to bother trying to build two manifolds. They are cheap and they have a very good shape and flow to them. The only drawback to these IMO is where the exit is located. But with a good coat of Silver ceramic, I think it will look pretty good. Plus, there is plenty of room for the downpipes.
In fact, the driver side could easily fit a 4" DP!
Please don't about my welding, it's the best I can do with what I have.
I was able to relocate the condensor without cutting any of the plumbing. Just some bending by hand.
This is the Radiator Mount that I made. The Griffen does not have any mounting locations so I had to come up with something. The Rad. seats right onto there nicely. the other end is attached to the frame rail underneath the car.
I had a freind weld on some billet mounting tabs that I had laying around. I'll probably weld some small tabs on for easy removal/install.
This was the first side that fitted.
This was challenging as a tight bend was needed. I did my best. It should look nice and clean when it's finished.
Driver side DP V-Band welded on. I guess I'll do the complete welding on the DP's only since they did'nt come out too badly. It will be wrapped up anyways.
I still need to make a DP for the passenger side as well as Fab the plumbing for both wastegates.
If you can buy a welder, you can weld! 5 months ago I did'nt know the difference between a MIG and TIG, 110V or 220V AC or DC. Nothing.
It's one of those tools that you can get by your whole life without ever needing. But as soon as you get one, you can't imagine how you lived all this time without it!
Kind of like DVR

Question, so far your at 6100+ and your labor, so how much HP did you get from D-1SC and how much HP will you get with the TT? Roughly how much to just buy a TT?
I'm still stock so i don't know what to expect from certain mods, but love reading all the info on here for when i get some damn CASH!!!
Oh, Braggin about yea i made that TT.... smurfING PRICELESS!!!
Props to you
Tint, Exhaust cuttouts, B&M Shifter Interior work in progress, LED mod done no resistors needed found replacements to match voltage and MCD. Shift knob and E brake handle next. SOLD
I'm no weld expert but it looks good. The machine probably paid for itself and alot of hassle.

VRM VRM --> I never had the D1sc on the Dyno at it's best. I can only guess that I was in the 600-700whp range with the setup I had. With this setup I expect to hit 750whp if everything goes right. Maybe more if I don't puss out haha. Each turbo is rated at a Max of 725hp each so as long as everything goes well, well, we'll see.
Danieloneil01--> Yes it has. I use it all the time. I think everyone should own one.
boostedinaz--> I had a completely different setup in mind while I was relocating the radiator. If you look in the pictures you can see that I cut out some of the cosmetics to accomodate this idea. It was too late at this point and so I just stuck with it. Allthough I still prefer this over the stock location.
I bought the first 112High Helix Magnuson blower ported for a GTO. Blew at 17k miles. );
Now I have naturally aspirated QSM 04 A4 243 Heads, Borla Duals, ARP Head Bolts,
05 hood, 05 interior, new 05 differential, 05 axles, Nitto 555r's, rolled rear fenders...

Were you going for a VMIC, V-mount intercooler/ radiator setup?

Silvergto115--> I know what you're saying and it would certainly make more sense to buy a quality piece. These are not all that though. Ebay IC's are one of the better quality china pieces out there and there alot of people running these IC"s with success.
This is the one I have in mind
This is the other option. I REALLY want this one and it has been in my plans for a long time. At 2X the price, it makes it a tough decision now. If I end up selling that car in my Avatar I'll defianately go with one below.
On the track I will be spraying Methanol aswell.
icon3037r... That looks like the 3rd Gen RX7 V-mount like the one in my Avatar? That setup would not work in the GTO without serious cutting. Or using Really small cores
The radiator would have been mounted a little bit lower than it is now. Just enough to allow a 3" gap between the top of the Rad and the top support where the hood latch is.
If you've ever seen a TT corvette that Speed Inc made, that is very similar to what I was shooting for.
Very nice. Very creative with the escalade manifolds.
How come you couldnt mount the passenger side turbo like the driver side? Did you really need to do that tight bend?
Also your belt is on wrong
I never would have known about that belt. Thanks.
The passenger side was a little complicated. The driver side manifold exits a little farther back and a slightly better angle. To achieve the same look, I will need a very tight radius pipe. After I had already finished this, I discovered these stainless donuts. I would also have to have T4 Flanges with Round Inlets so the Pipe can immediately start turning.
looks real nice how is the plug wire clearence with the manifolds like that?
There's just enough room for them. I'm going to look into the Non-Sponsor custom wires and see if he can put 90 degree bends on the plug end. They will have to run right up the block to the stock coil location.
Originally I was planning on relocating the coils but I think this way will work well.
Thanks SOFAKINGGR8...Your setup looks real nice. Since it's only a couple hundred more for the Treadstone, I'm probably gonna go with that.
I've had some troubles trying to cut/grind out holes into the piping for my wastegate plumbing. I did not anticipate this being such a PITA
I only have small 10 gallon air compressor and its just not cutting it for the die grinder. Last night I ordered a Champion CT-7 Carbide Hole Saw for metal as well as an Irwin 5-35mm Unibit. I will hopefully get one of them before Saturday. Hopefully I can slice thru this SS a little quicker and keep up some momentum. I also have 2 02 sensor bungs and 1 more for the WB.
