Does any one know what trim/ar I would need for a garret gt35r. My tunner gave me specs to go with a .84 trim on the hot side and .70 on the cold side. Only problem is I can't find this trim for the cold side am looking to run 15 psi on the street and 21 psi at the track. Any help would be greatly appreciated.

 

I suppose your talking about A/R sizing not "trim" ...for rotaries i suggest on not going with a small .84 turbine.... go with 1.00 or 1.06 minimum. Regarding the compressor side the .70 is standard. www.a-spec.com has the turbo you're looking for in-stock.

good luck

 

All you will need to know is GT35R. They only come in one trim 56 for compressor with a .70A/r, 84 for the turbine. A/r's I have available are .82, 1.06 T3, in T4 sizes are .84UD, .82D, 1.0D, 1.06D, 1.15D.
D=divided UD=undivided. I would go with the 1.0D it responds as good as the T3 and doesn't drop off up top like the T3's.

 

Thanks for the clairification on this.
