I spent the last 6 months installing a twin turbo system to the LS1 in my roadster. It has 2 Garrett turbos, Tial wastegates and blow off valves, 2 pre-intercooler intercoolers, 2 fully independant water to air intercoolers with heat exchangers, water/methanol injection (boost cooler), on the fly electronic boost modification, custom made alum intake tubes, no mufflers but kept the cats for now. Had to make 4 custom reservoirs and of course completely redo the exhaust and cooling lines, again.
Currently using 5 psi boost until I can get back to the engine for internal upgrades, someday...
Still need to install a catch can and vent the crank case better but it runs and works well. I will upload some pics in the next week or so.
Time to get back to those doors...Would I recommend doing turbo to anyone? NO. Just figuring out how to tap into the coolant and oil for the turbos was a nightmare and took a lot of custom work. Not to mention the cost, cuts, bruses, and fustration.
If anyone was thinking of doing this I would put this at a difficulty level of 8 of 10. Not a 10 of 10 simply due to the electronics being very easy to setup. |

| Been running for a few months. The turbos, intercoolers, boost cooler, etc are completely setup and ready for a dyno run some day. I am back to working on the doors. |

Turbos = 2000
Blow off and waste gates = 500
Gauges and electronics = 800
Water pumps (3) = 400
boost cooler = 600
Intercoolers = 400
Various plumbing = 800
Sensors, stainless pipe, silicone couplers, t-clamps = 500
Engine upgrades good to 10psi boost:
Injectors = 600
Gas pump to 1000hp, pre and post filers, heat sink, etc = 800.
Custom fabrication on 4 resivors, mounts, exhaust, etc = priceless...
You could easily cut that cost down. I went with the best I could find. You could also setup a V12 for that price but I did not want to go through the hassle just yet and I want twin turbos for fun and the sound, for now. |

| That it is. There is a good 1 to 2 inches between everything that gets hot. If you only put 5 to 7psi boost the water to air intercoolers and the boost cooler could be left out. That would open up a lot of room and cut the costs down considerably. Its hard to see but there are really 3 layers of "stuff." The drawback is if I need to pull the transaxle or something close to it I have to remove everything. That alone would take 4 hours of disassembly. |
