new internals

09-23-2004, 10:14 AM
Has anyone rebuilt their turbo's with upgraded internals. There is a local rebuilder here in Orlando that does all of my turbo rebuilds, and they said that they could trick out my turbo's. I believ that they said that they would re-machine all the housings to accept larger/stronger wheels. I was just wondering if anyone has done this, and what sort of results it netted.

Yes you can. It is done here quite often since aftermarket turbos are so expensive here in New Zealand.

They use a T28 shaft (same as the GTiR) with steel wheels on the compressor and turbine. The core is bored out and a bushed bearing inserted, with the housings machined out. Also don't forget to get the internal wastegate opened up as large as it can be to relieve the extra flow.
Power should be good for around 500ish if done properly.

do you use a 360 degree thrust bearing??

My turbo rebuilder mentioned using a ford turbo coupe (thunderbird) compresor wheel, but I am not certain as to what other specs he was thinking.
