This... and holy shit this is goign to open the door on the GR and UR engines... I've been practically salivating. What would I pay to be very close friends with a rogue Toyota ECU engineer ***sigh***

So that article seems to say that D-4S achieves very good fuel mixing and combustion efficiency compared to your typical fuel injector setup. Now the GR engines were rev limited pretty low as I remember, but someone said it's possible to get a crapton more power out of them. Does this require new cams though? I definitely remember looking up that motor, torque drops off towards its low redline, sounds like cams weren't that aggressive. |
Yeah.. these engines have a shit ton of power corked up in them and might even be slightly underrated. I think I need to buy me and engine brake setup and a couple 2GRs.. someone needs to crack this puzzle...
