I'd say you could try my turbo, but I don't know if i'll be using it soon. It's a tad on the large side and all I know is it'll flow 60lbs per min.
Not to mention it's bloody heavy, and a twin scroll.
what's the new turbo you've ordered?
Anoter quick question. What size compressor wheel were you using with that turbine wheel as the hot side look fairly small, GT/T28 sized infact.
