Interesting post on http://www.gt4dc.co.uk/forum/viewtopic. ... highlight=

This is the same turbo that was fitted to the Toyota IMSA GTO car that was demonstrated at Goodwood Festival of Speed this year. According to Toyota the 2090cc 4T-GT engine made 456bhp in this guise.

In the Toyota 85C Le Mans car a maximum of 503bhp@7,600rpm was achieved using a revised Denso ECU although it is unclear if this used this particular turbo. My sources indicate that a CT44RT was employed on the later Le Mans spec 4T-GT.

I don't have any details on what turbo was used in the Group B Toyota TA64 Celica which also used the 4T-GT engine. Can anyone shed any light on this?

Thanks Gary, another piece of the jisaw puzzle is now in place

According to Ian Bamseys book the CT44RT and ST turbos used on the Toyota 96C Le Mans 4T-GT engine were based on the KKK turbo.

I think the Porsche 956/962 sports prototype also used KKK turbos but the Toyota's were always struggling for pace compared to the Porkers. They tried the turbo 16 valve 3S-GTM engine in the 87C before moving on to the V8 R32V engine in the 88C-V.
