thats one of Sound Performance's turbos, they are one of the main Supra shops in the US and located in Illinois I believe. Their line is like SP57 (being smallest), SP63, SP67, SP71, and then another one I believe.



But that shop is pretty much a Supra shop, thats what they specialize in. So that turbo is mainly a Supra application.

Yea, to add to that, they are also well known for quality and quick spools. Of course, though, if you go big, there's more lag. Lag is different for Rx7's than a Supra I'd presume...how much of a difference would putting the same turbo on a Supra vs. an Rx7 do as far as full boost rpms?



I believe they have an SP88 now, takes forever to come on (4-5000rpm) and is too big for anything practical, most recommend the 74 for a balance of power/spool.



Yadda yadda yadda.
