That 1.8T turbo should do fine.
I doubt it, my buddy has a 1.8t and while they are small it hits fully boost at like 3000 rpm, and this thing is 14 times smaller and only puts out 9 lb/min mass flow so im prety sure we could try all day long and it would not work, i want a really small turbo that is gonna build boost prety soon and hold it, not something that is gonna hit at like 7000 rpm, and like i said i cant just throw any turbo on i have to give mathmatical reason for choosing a certain turbo, and therefore have to chose the proper turbo for the application.

i called one place and they said that their manual clutch wouldnt hold up to the boost and would just rip out, but im gonne see if a local guy can build a manual one, either way im not looking for anything special its more the fact that the project is turboing it than it being a sweet bike

its a small turbo, but i think its too big for this application i dont think it will fit, not to mention that manifold would be a pain to take off and put something else back on, cast blows....
