T-25, 62 trim 53.8mm 0.64 A/R turbine ??? wat does this mean
i can get one of these turbos cheap from a jdm nissan
i was wondering if this would be good for a d15 and wat in the hell does all those thing mean!!! T-25, 62 trim 53.8mm 0.64 A/R turbine |

thats a little big on the exhuast AR for a 1.5 a .64 would be better suited for a 1.8 or high revving 1.6

Whomever told you those numbers doesn't understand how TRIM and A/R are calculated, they're two different things. Trim is the outer diameter^2/inner diameter^2*100. A/R (area/ratio) is how the exhaust housing and compressor housing are defined as a size in reference to the turbine wheel or compressor wheel that is inside.
http://img64.echo.cx/img64/430/dsc001426ry.jpg Technically it is defined as the inlet (or, for compressor housings, the discharge) cross-sectional area divided by the radius from the turbo centerline to the centroid of that area. http://img212.imageshack.us/img212/2729/ar0em.gif That being said, look on your compressor housing and see if it says .80 or .48 If it has a .80, it could be a 60 trim or 70 trim. The 60 trim would measure 1.66" minor and 2.14" major for the .80 housing and 1.57" minor and 2.02" major for the .48 A/R housing. Both of which would still be a 60 trim wheel. The 1.66/2.14 with the .80 A/R housing is capable of 27 lbs/min and the 1.57/2.02 with the .48 A/R housing is capable of 28 lbs/min. HOWEVER, you could have a 70 trim wheel in a .80 A/R housing as well, which would be the largest of the T25's. The 70 trim wheel measures 1.79" minor and 2.14" major and is capable of 32 lbs/min. All of the T25's have the same turbine which measures 1.64" minor and 2.09" major. 53.8mm=2.118" which none of the T25's have. Whomever told you that number either made it up, or sucks at measuring. My guess is both. |
