Has anyone ever turboed a 2.8 v6 in a B4?

I have a shop that would fab a custom manifold is it worth trying ?
Or should i say F*** it and just get an M5 ?

Any info would be greatly appreciated

i'm sure it's possible... lower the compression, fab intake and exhaust manis, run 034efi stand

alone... and $20k+ later, still not make the power of an RS2'd 20vt

not to discourage you, but it's more time/$/hassle than it's worth.

Definately don't waste your time. If it was a 7a I would say go for it (everything is already made

for turboing it). The 12v really isn't that robust.

I don't remember this being asked before but can the 2.8 12v block be "bored"?
