the GReddy t78-t88 turbos were not actually 78 or 88mm.

the T78-33d(most common T78) was a 65.8mm inducer aka T66 in the garrett/pte world

the T88-34D = T70 in Garrett spec.

both still quite sizeable. but such dated turbochargers by todays standards.

loads of supra guys are still running 76mm turbos though, with the new Billet 76 from precision, and garretts new billet wheels…

even the new precision 71mm Billet. its making over 900rwhp. pretty amazing for a smallish 71mm

even the new 67mm’s make 900whp now its unbelievable. soon the outlaw cars will be running 62mm units.
