Hey guys, I recently picked up a turbo for next to nothing w/ the plans to have it rebuilt. The turbo is going to be used for a custom kit that will be put on my 2.2 Ecotec. The turbo is off of a 1983 Nissan 280ZXT. Now I know that the A/R on the turbine section reads .63 but the only thing listed on the compressor side is Nissan. I know the turbo is a Garrett T3 but I am having troubles finding the EXACT specs on the turbo and a compressor map for it. If you guys could be any help that would be great. Thanks a ton.

i bet the fellers down at www.zdriver.com would be able to help you out a lot better than here.....

if your looking for a 280zx to throw it back into....let me know, ill hook you up.

Ok I finally found out where to find the other a/r reading and i feel retarded for not looking there to begin w/, thank you. Now about the compressor map, is there just one general compressor map for a 60 trim or would there be different ones because of the different a/r numbers?

should be different maps....what numbers did you finally come up with.

The turbo is a Garret AiResearch TB03 60 Trim Turbo .50 A/R on the compressor side and .63 on the Turbine side.
