rb30det (about to be built)
gt4082 - can get 1 for cheap-ish and also can get a tial 38mm wg.
max boost atm will be 14psi, hoping for ~270rwkw ?
Would the 38mm do the job fine at 14psi ? Eventually will push closer to 20psi+ after a forged rebuild.
(PS: Sorry, i did try using the formula, but as i have no experience what the 30det with a 4082 would make on certain psi, i wasn't able to calculate properly...)
