in viewtopic.php?f=55&t=1560. Not that I really think I need another thread for my car.Sounds like it might be time for a thread about the car itself in the user rides section with that sort of info.

The smaller Volvo turbo came with its stock waste gate actuator, and I decided to use it since it opens up into the bigger turbo anyway. Plus I didn't want to destroy it by spinning it too fast, because it did come off a 2.2L, I think. I have an electronic boost controller for the secondary turbo's waste gate, but it's not currently on the car. I decided to hook the secondary waste gate directly up to the boost so that it opens fairly quickly. Despite what people may think, I don't want to burn the engine up while screwing around without it tuned properly. Sequential, I guess, I call them compound, but same thing I assume. NO you can't have more pictures, because then everybody will see they're on there just for show. lol1. how are you controlling the turbos... they are sequential, right ? can we have more pics of the exhaust manifolds (showing all the plumbing to the turbos), and also the intake side of the turbos ?
The setup was originally a cheap kit from ebay.
Then I got into it with my shitty mig welding skills, and fixed it up good. I tried to make really nice bends, but a couple are a little tight. My main goal was to raise the ground clearance, and the second turbo was kind of an after thought. The exhaust is stock from the front of the cab back.
Yes, I used rebar to support and stabilize the pipes so that it wouldn't crack the welds from two turbos hanging onto them.
Ground clearance.
Coming around the oil pan on the left, and going to the tail pipe on the right.
The bend at the top of this picture is a little too tight.
The bend around to the secondary on the left, and the down pipe off the secondary on the right.
Intake side.
No idea, I've never even seen a dyno in person. 1. I never installed a gauge in it. 2.The OEM setup wouldn't let me spin the turbos up. It would throw a high MAP sensor error, and stop injecting fuel. 3. I'm at about 7500ft in elevation, so I'm starting off at about ~2.5psi less than someone at sea level. I got the engine out of a junk yard for $200 with 60k on it, and stuck it in my car. Wikipedia lists it at 10:1.2. modern 3.5L v6 with boost... what sort of power is this making ? at what boost ? I take the engine compression is stock ? (which is?)
The reason the engine was so cheap.
