Are these CT20 turbos?

Postby 2jz tt Aristo » Tue Sep 25, 2012 10:35 pm

Hey all, i grabbed a couple turbos for next to nothing to get rebuilt and highflowed, i was told they came off a 2jz which looking at the bolt ups for manifold seems correct.

Problem is there isnt any markings on the turbos to confirm or deny they are CT20's, so i took off the turbine and compressor housing to measure the wheels:-

I found this link, seems to confirm but would like some input from you knowledgeable fellas!!

Yip thier the ones, came with a box consisting of 2 sets of manifolds, downpipes and intercooler pipes. The only part number i could find was the std bov which came off a 1jz Soarer! But have found there were 2jz and 1jz manifolds, 2jz downpipe and 1jz intercooler piping.

Turbos are in decent nick too.

Looks right - the inducer measurement for the compressor comes across as a little small due to the way you have measured it, the inducer measurement relates to the diameter (even though there isn't a solid "circle" like you were able to use for the exducer) - ~38.5mm is what you'd be looking for on the inducer, I reckon that looks like it is in the right range.

Yer it was alittle tricky getting an acurate measurement, i span the wheel to help get the true radius. Im pretty confident they are CT20's.
