well, this turbo is also known as the Hight Tech Turbo HTPS. It's manufactured by Turbonetics.
It fits perfectly in the stock location. No problems at all. It includes a new boot that connects the turbo inlet to the factory CCV vent bracket.
and the whistle is COMPLETELY different...and the surge is gone!
when you're running 30+ psi boost, it still pulls strong, and is it's turbo map!
