the s475 is a s400 turbo. i think the 475 will do fine. now is the 1.10 or 1.32 a/r better? would the 1.10 flow air faster and the 1.32 flow slightly more air? once again 40 or 50mm wastegate?

ok talked to the guys on the phone from DP that built his own today, super nice guy by the way. sound like i can get this done for more like 1800. here is what im looking at so far for the setup.
S475 1.10 A/R turbo
50mm wastegate
aluminized steel intake tube
alum steel exhuast tubes with heat wrap on the transfer pipe
probably going to throw a blow off vavle on the boost tube coming up to the engine just to be safe.
going to start planning and fabing stuff up very soon. need a dowpipe from a LB7 if anyone has one around. need to cut the end off for my transfer pipe.
