Help identifying Turbo
Hi everyone,
I bought my car with what appears to be a SR20DET turbo on it. It has gone bad and is burning a lot of oil. The intake ar is .80 and exhaust AR .86. Says Garrett on the side and M24. The compressor wheel measures: OD: 60mm ID: 42.39mm Turbine: OD: 52.88 ID: 45.14 Can you guys help me identify this turbo? It is on my 1990 1.6 liter making 13psi of boost and spooling around 4300rpm. Going out to grab some pictures now... |
On the CHRA, the riveted Garrett-branded tag will have a few part numbers. Punch them all into Google and see what comes up. Off the top of my head, though, an M24 casting on the comp cover and a 60mm comp exducer indicates it's a T25/GT2560/SR20DET/related turbo.

Unfortunately there was no tag on the CHRA.

Without the tag, you're spitballing. Google's guess is as good as ours.
I will say that the 0.85A/R housing is not desirable at all with that turbo. You really want the 0.64. The 0.86 Garrett housings are only beneficial once you step into the 2860RS/2863/2867/2871 neighborhood. At the power goals of a stock motor 2560R setup, the small housing is definitely better. |
