another update.
i recieved a full refund for my old md240r turbo, which i had nothing but grief from.
my new turbo is on its way to me for tomorrow or tuesday.
its same size compressor side (enough flow for 550bhp),
with a larger 0.82 turbine housin, ( should be able to flow 520+bhp)
its rated to up to 4 bar boost, but should be efficient/maxed out about 2 - 2.6 bar (30- 38 psi)
lookin for a proper 510 bhp, which is about 50+ bhp more the old turbo ever run in car.
