Title: Which GReddy T78 suits the RX7
Post by: antnicuk on June 20, 2004, 10:48:23 PM
Does anyone know which model GReddy T78 turbo suits the FD rotary?  GReddy dont print a/r ratios on the housings but they seem to have about 4 different models.   It is a very popular turbo in the us and japan.

I know Gurj has a T78 with good results, you dont happen to know the model of it do you?

Regards
Tony

Those figures in the other post are way out for a rotary engine car.

Hi Brian,

yea those figures are alittle optimistic for a rotary but can still be used as a guideline into which turbos make the most power and so forth?

As a T78 on my car makes aronud 460bhp but the same turbo on say a r32 skyline will make up to 780bhp, as have actually seen this for sale. Obviously the rest of the engine would also be upgraded but just quoting
