My Build - 2002 TA 408 - Twin 67's UPDATED DYNO NUMBERS 4-19-12
970 RWHP @ 20 PSI
Hey everyone, I figured since I got my ride where it moves on its own power again, it's time to show it off. There's still a couple of things to finish up on it (exhaust, coatings, installing my meth kit and final tune) but she's running and turned out better than I could have expected for a first time turbo'er.
The car's been down for about 2 1/2 - 3 years now (long time I know) but during that time, had a lot of stuff go down in my life with family and I got married and recently moved to Dallas...so working on the car didn't get put on the back burner by choice but by necessity. All the work below was done in about a year, a weekend here and there traveling back up from Dallas to Arkansas when I could (car is in AR still).
All the work was done by my friends and I in their shop. When I say shop, its an industrial mechanical fab shop (conveyors, machine automation, lift tables, assembly line design, the works), and I twisted their arm into stepping into the automotive world. They said they had no clue as to how to fab a turbo kit up, but they can weld like all get out so, I said we had a deal. Going off of a lot of reading from this site, we came up with the basic layout of the twin kit and stuffed it all in the front of the car. The finished product looks amazing to me, but I'm a little partial
BTW, I've got pics of everything if anyone needs anything they don't see here...just trying to save space on the thread. Anyway, here's the setup:
408 ci iron block assembled by Speed Equipment World in Fort Smith, AR
JE -22cc forged pistons
Eagle Forged Crank
Eagle Forged H beams
Ported 317 heads with 2.08/1.60 valves (next upgrade purchase will be here)
Jesel J2K Mohawk Rockers
Comp R Lifters
ARP Studs and hardware all around
Turbonetics TC67's from Jose at FI
Turbosmart 38mm Wastegates from Jose at FI
Turbosmart BOV from Jose at FI
GMPP Single Plane
Aaron's Intake elbow
NW 90 TB
Fabbed Intercooler with Treadstone Parts
4L80E Transmission
Yank SS 3400
Moser 9" Narrowed 2.5" Each side with 3.00 gear
All good suspension stuff from Spohn, BMR, QA1, etc.
Dual intank Walbro 255's
Alky Control Dual Nozzle Meth Kit
FIC 96lb High Impedence Injectors
HP Tuners 3 bar
Here's the pics...and I've got a bunch of em'.
Cleaned and painted engine bay with HVAC Deleted and SJM ABS Delete/Line Lock Installed
Motor sitting in for the first time in a while
Moved it to the shop and began working on standing the radiator up vertical
Here the radiator is installed with the hood latch mounted
Tacking the tanks on the intercooler - Its a Treadstone core that I wanted to make 2 IN and 2 OUT...I know it doesn't matter that much at my power level, but I'm not a huge fan of the 2 IN - 1 OUT design that necks down the outlet to 3" instead of 3 1/2".
Time to start fabbing up the cold side - 2 1/2" mandrel bent from Columbia River Mandrel Bending
IC Mounted and starting on the cold side fab work
Finished the tubes connecting to the IC
The 2 into 1 merge from the intercooler to the TB 2 1/2" to 3 1/2" V Banded
Now working on the tubes from the IC to the turbos. From mocking up things, the best looking path for the least tight bends was through the frame. I believe that LASTLS1 had his done this way and gave me some ideas. The turbo sits right on top of these where they exit the frame and are coupled there.
Here's the complete cold side kit removed for final welding. Comes apart very easily and you can see there aren't any crazy bends.
Hot side time, here's the flange to the turbo with the flex coupling
I'll skip the mocking steps and show you the finished products of the hot side fabbing. I really like the wastegate angles, as they follow the best flow path on the outside bend of the tubes.
Passenger Side Turbo and tubing
Turbo Kit completed, sans powdercoating/coating
Installing Fuel Goodies
Dual intank setup, with some fabbed up pieces from the shop and work
Installed the rest of the fuel components and intake stuff
Got the cold side powedercoated black, threw on some filters, and first attempt at the fog light mounting. (I was out this day and they didn't know that I didn't want a bar running in front of my IC..lol)
Good look at setup with WG's top down
Revised Fog Light mounts
Final Setup
Oil Filter Remote Mount - Under Drivers Side Headlight
Overflow Tank - Under Passenger Side Headlight
Cover we made to hide the gaping hole in the front bumper where the license plate was cut out, powdercoated black
Gauges mounted in vents - Eboost 2 on left, AEM Wideband in Left Middle one and AEM Digital Fuel Pressure in Middle vent
Moser 9" assembled
Optima Relocated to Rear - I can't find my picture but I put my cutoff switch through the tag and looks super slick
Fuel Pump Hatch and Hatch Door
Car as it sits now...that front end is LOW with all the extra weight that was added...need to adjust the QA1's up some more
Anyway, here's the final product...a short vid of me driving up, idling for a sec, then rolling off smoothly (this is our little test road btw, its about a mile long, straight, very little traffic, very nice!) Still breaking her in though and will put some more on here as I get to take em'.
It's open downpipes right now, so it sounds wicked but would be too much for a frequent driver, which it will be. Anyway, I hope to have Dallas Performance do the exhaust on it and have Taylor look over my tune and make sure I don't send something flying at high boost levels (tuned several NA things, first run with FI and I'd rather let my pride take a back seat to my wallet if things go awry)
Thanks for looking and I'll update this again when I get some dyno numbers and track times...shooting for around 1000 to the tires, but will see what I can get with the heads on it currently. Anyway, until next time, thanks for all the help and great posts on here...I couldn't have done it without your threads and ideas! God Bless!
Also, HUGE HUGE HUGE thanks to David and Chad at the shop and my main man Twatson (his name is Travis Watson, so combo them together and viola!)! And I guess I'll thank my wife, Jordana, for being so understanding of why we haven't went on vacation in two years due to lack of funds...jk...but she is the best thing that's ever happened to me..only problem is that she doesn't like fast cars or loud ones....I'll have to work on that...lol

Wow that's awesome, what power did it make?
Also what size cam are you using? just wondering as doing a 383 stroker with my ls1 ( i know 383 and 408 a little different in size) and deciding if to go twin turbo on that as well, will be doing similar building engine my self and my own turbo kit.

Fyi, i ran the fuel pumps into a block i made at work. Ive got a cad drawing of it ill upload too. Reason is that i coundnt find a Y that would fit in the tank with the bucket. This piece also acts as the bottom connection to the bulkhead on top, which is a -8 AN to i believe a 1/2 npt in the block (ill verify with the cad file).

As for the cam,its a comp hydraulic roller 232/238 .605/.609 on a 114.
Sounds good to me...hope it performs just as well when i get it on the rollers!
Good luck to you on your upcoming build
