Xnke Posted August 8, 2011 Share Posted August 8, 2011 Ok, so I bought a AiResearch T4 turbo from aplyedmind here in the classifieds. It needs a rebuild, and that's no problem...but I'm trying to figure out what it is. It's an old farm turbo I think. He'd cobbled it together with a section of pipe since the exhaust housing does not have a flange to bolt a downpipe to, but I think I can do better. The wheel sizes are as follows: Compressor wheel: 2.153" inducer 2.758" exducer This kinda corresponds to a T04B wheel...but not quite. The inducer size is smaller than I can find for any T04B wheel, but the exducer is correctly sized. Turbine wheel: 2.890" inducer 2.495" exducer Closest thing I can find is a T4 P-trim wheel. It's got an odd number of blades so it's hard to get perfect measurements. The exhaust housing has a .96 A/R and the compressor housing isn't marked, other than AiResearch and M27.
