I have the Turbo which comes in the DRAG III kit, Turbonetics T3/T04e

I wonder which A/R and trims this turbo has......and what to modify when I want a bit more top end.

 

.63 ar exhaust with .54 trim compressor. or it could be something slightly different but thats what most of them are.

 

exhaust trim is okay IMO, but compressor a/r is a bit too small, right?

What means 54 trim or 60 trim?

 

what i would do is t3 60-1 or something in that neigboorhood i know louis is doing a gb on them right now. with .82 housing that should spool slower but more top end.

 

The trim is reference to the compressor wheel's size and ability to flow air. The 60 trim wheel will flow more than a 54 trim wheel. The 60-1 compressor that Viren mentioned will make awesome power, but it requires a new wheel, new compressor housing, and new backplate.

I do lots of autoX and I am happy with my relatively wuick spool, I don't wont to miss it. I get a new turbo manifold which is supposed to give a quicker spool (tubular mani). Therefore I thought about to modify the turbo slightly, I only want a bit more top and and no big lag.

 

if you do it slightly take it up to larger compressor side trim.

 

yeah, that it was I thought, but what a7r would be a wise choice
