I am looking for the closest DSM match to these specs..

TURBINE:
Wheel = 53.8mm
Trim = 76
A/R = 0.64

COMPRESSOR:
Trim = 63
Inducer = 47.7
Exducer = 60.1
A/R = 0.60

 

help

 

Well, when converted to metrics the "big" 16g compressor wheel is:

46.82 in
60.2 ex
50trim

The big 16 comes with a 7cm2 housing with the TD05H hot side (as does so many of the Mitsu turbo's, so the a/r is smaller than you want)

Trim on the hot side is:

49.02 min
55.88 maj
77 trim

Mitsu a/r conversion for their housings are as follows:

6 cm2 = 0.41 A/R
7 cm2 = 0.49 A/R
8 cm2 = 0.57 A/R
9 cm2 = 0.65 A/R
10 cm2 = 0.73 A/R
11 cm2 = 0.81 A/R
12 cm2 = 0.89 A/R

The big 16 is close, but the a/r is what your not gonna get for the mostpart with the common td05h 7cm2 configuration.

20g's do have 8cm2 and the larger 10cm2 housings if you can find them which is more inline what your looking for, but the 20g compressor isn't what you wanted. Could look to a hybrid combo maybe.
