its actually from a LS/GS400 
currently the trick mod of choice by Toyomoto Turbo and S/C cars...
you cannot just "slap" it on....it needs to be custom cut and welded onto the intake manifold Y piping...I suggest if you're in cali, try SP ENGINEERING
good luck!!

The LS/GS/SC400 share the same engine and therefore throttle body. It measures 75mm. The work and cost necessary to use this larger unit would be substantial. Because of this I have 2 questions: What is the IS300 tb size? Is there even a documented improvement to going larger? Maybe above 600hp... maybe... but below that... I would need to see strong evidence of substancial improvement.
