Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
Neat. So the exhaust goes through the big turbo then into the little one, or is it split up somehow?

why not just get a modern twin scroll turbo instead of messing around with such an outdated and complex setup? Both of those turbos have designs that are over 30 years old...
yeah, sequential turbos are fine to help a giant turbo spool up at lower RPMS, but the turbos you are choosing are old 70s junk and can easily be supposed by a modern twin scroll turbo in both quick spool and high RPM boost. The 2 examples you posted was a huge semi-truck diesel engine and a 2000+ hp drag car. your car is neither of those. Why would you specifically choose to create a sequential turbo setup with old turbos instead of one modern one? you could put a GTX3076R on a stock b230ft exhaust manifold and make more top end and power under the curve than the sequential setup with a T3 and 13c. Less weight, less complexity, less oil and coolant lines.
I see your wiki copy-paste, but those setups are not appropriate for your low horsepower small engine. My billet 20T made 20psi by 3200RPM, is that not fast enough spool or power for you? even that's a cheap 90s turbo on a 2.1L...

Well i don't now of a turbo that can produce 2 bar(30 psi) boost at 3000 rpm on a 2.3 liter engine and hold it to 7500 rpm. Without producing a lot of back pressure at higher rpm. The plane from the start was to use a supercharger at lower rpm but I don't have the machinery to make all the parts to make it work. So a took a smallish turbo to make it spool up fast. So the small turbo is to small to make any real power at higher rpm so the big turbo makes all the power at higher rpm. The t3/t4 turbo will be change to a holset hx35 turbo later. I don't only want high end power but also a lot of down low torque.
all RWD Volvos are junk, I know mine definitely is a $40k pile of smoking garbage...

I do like your angled compression turbine clamp; where did you get it?
BMW has some little air-water intercoolers. They may fit between the compressor outlet of one turbo and the inlet for the other.
