I'd say ditch the dsm setup idea and go with a decent log manifold, t3/t4 or a gt series turbo and 280 won't be a problem.

Look up some of my old threads and you'll find my setup, but the gist of it is this:

Log mani
t3/t4 .63/.60
3" exhaust (Clears A/c)
tial 35mm w/g external dump
2.25" i/c piping
20x9x2.25" fmic
stock block h23
delta 260's

280whp/260tq @ 9.5 psi.

Ran great, reliable even with 180k miles.

Ran a 13.2@105 with only 245whp @ 8psi

Never got a clean run in with the updated setup before the fuel pump quit at full boost and melted all 4 pistons.

It is feasable, and reliable when done right.

^ what about teh "big" 16g on the newer evo's ?

The EVO III 16G is the only "Big" 16g that will work with the dsm manifold. The other 16g turbo's are designed differently.

There have been very few reliable dsm setups done here.

The best thing you can do is get better pistons and rods. Spend the money on that.
