Will need to be dual wastegates I would have though mate? As each one will flow different amounts of air. So will need to be set up individually?
are you venting off 2 cylinders to each turbo then ?

but if you have the waste gate before the turbos then you will not need 2, this kind of idea
it won't matter what way you compound /seqential connect the turbos
other example

im just thinking wouldnt it have been better to have runners 2 and 3 feeding 1 turbo and 1 and 4 feeding the other ??
No such thing as full boost by 3000rpm, no matter how bad you want to sound like.
Ok, so imagine your running 15 psi, and your saying you get right on the sport 15psi at 3000rpm = rubbish. There is no such thing when people say full boost by X amount of rpm. Since your saying you get full boost by 3000rp, so does that mean your getting 5psi at 1000rpm. Sounds like jack shet if you ask me. Ok, so 10psi at 2000rpm, i dont think so.
Somebody mentioned using VNT turbos. This IMO is no better than using an external wastegate. I suppose an external wastegate is probably more reliable than a variable vane turbo (vnt). VNT's give alot of bother in VAG motors with carbon build up etc. I would stear clear of them for that reason but on the other hand I would like to see what power a GT17 would make on a 4E!
VNT turbo's will still have a wastgate to control the boost but has ajustable veins on the exaust side to control the flow to minimise lag,
