Another question. Whats the difference betweent the Big 16G and the EvoIII Big 16G? Which one is better?

 

EVOIII 16g. More efficient, flows more air, higher max HP.

 

well, which one spools up quicker? and holds power throughout rpms?

 

Outwardly they look like any other 16G. They use the same compressor housing, TDO-5 exhaust wheel, and the same 7cm volume exhaust housing. Until you pop off the compressor housing... HELLO! Big Wheel. Flows 550 cfm vs. 505 cfm for the regular 16G.
The normal 16-G compressor wheel is 1.83" at the inducer and 2.36" at the exducer. The Big 16-G is 1.89" at the inducer and 2.68" at the exducer. That is just over 5/16" (8mm) larger than the normal 16-G exducer and the same size as the GReddy 18-G (inducer diameter is only .10" smaller than a 18-G).

 

in other words, the Evo3 Big 16G. Well does anyone know at what rpms they spool up at?

 

Well I hit full boost at 2800rpm, but then again I have a 2.3 stroker.

 

Lol, you don't count, lol.
Look at around 3200-3400rpms.
MHI stands for Mitsubishi Heavy Industries, which means that it's a Mitsu turbo, that's all. The EVO316G is what I would get because the only bad thing I've ever heard about them is that they look small, lol.

 

Yes they do look small, but dynamite come in small packages! lol

 

Guys, i decided to go with the Big T28. Thanks for your help.
