Frankenstein Evo 3 16g turbo power Output

[LeeSD1]

Okay well to start off Im new to turbo's and calculating specs of turbos But I have a normal evo 3 16g turbo except the turbine housing is a T3 AR.73 with 2" outlet. Now I just read that it was an AR.73 because the guy said the housing is a 10cm^2 turbine housing. I know its a huge turbine housing for such a small turbo but its the only T3 housing I have that fits on a 16g. I dont get full boost till around 4-4400rpm and thats only 10psi.

NOW(im about to drop in a built short block) and my question is, if I run 20psi can I hold more boost at higher rpms? or will it still just spike and start falling off? And since this turbo is rated at 380hp would i be able to possibly push out more since it has a bigger turbine housing? or will it not since its still the same wheels?

you would of course expect to hold more boost at higher rpm due to the lag but i read a thread where its not a horrible lag and manageable as in it feels fine to drive. It would reach its potential but over a larger power band, Its definitely not ideal the point of a 16g is fast spooling in the first place, so i would recomment buying a tdo6 wheel the one thats actually made to fit that housing(i believe hks made this hybrid 16g tdo4 or 5 compressor with 10cm housing tdo6 turbine) or just use stock housing and stock manifold and be done with it for the time being. It looks like your wanting a bigger turbo tho since you have a t3 mani and a built bottom end so might be time for an upgrade all together.

We can't possibly tell you what sort of power the turbo can generate until you clue us in on what turbo you have. The numbers you've posted are 100% useless....we need photos and wheel specs.

I said it was an original evo 3 16g so the wheels are that size. I will search for the sizes on the wheels.
All I just really want to find out is if this larger turbine housing is beneficial in any sort of way and how. Im trying to save up to eventually get a gtx30 but till then ill try maxing this turbo out.

If it has Evo III wheels, then it's not a Frankenstein anything....it's an Evo III 16G with a different turbine housing.

Full boost at 4400rpms is worse than poor for an Evo III 16G. That "special" turbine housing is doing nothing but causing you unwanted lag as the Evo III has already been proven into the low 10's using the 7cm turbine housing which comes on it from the factory.

My suggestion is to lose the T3 housing and manifold, and go back to a factory DSM bolt-on setup....or buy yourself a T3-flanged turbo that is more worthy than the Evo III 16G.

Yeah well I dont have enough money for a new turbo so im stuck with this one. And I cant find turbo manifolds for the 420a that can bolt to a 16g. I know all that lag isnt any better but its the turbine housing that came with it.
