Hi,

I'm finally ready to start spending some money to build a GT, so I've been starting to look through e-bay for turbochargers as something to start from.

I came across this. When I calculated the postage to Bathurst it came out around $20 extra. Is this something I shouldn't touch or worth looking atconsidering the cost ~$40 seems to be fairly cheap.

Cheers,
Rex

I have used one of those turbos for a GT before. It worked, but the turbine is a bit small for the compressor size and TOT was very hot (700+°C) no matter what I did with the combustor.
I also sheared the blades off a turbine wheel, probably due to a combination of surge and overheating.

I swapped that turbo for one from a Mitsubishi Cordia (or maybe Starion). It has a huge turbine compared to most car turbos, and worked really well, with TOT around 550°C

I also had some success with a Toyota CT20 turbo - but I'd recommend a CT26 if you can find one.

here's a video of the jet running with that turbo.

It's using a Rolls Royce Dart combustor can, which I tested to hopefully reduce the TOTs, but it was the same as the old combustor, which was super basic and made from an old car exhaust resonator
