well im unsure what this peice of engineering is, i know it was made by TOMEI cause it has it ingraved on the top of the adjustable ****, i thought it maybe a boost controller, but it has 3 vacuum ports it seems. so if anyone has seen or come across, how does it work? any info really would be great. was found in the glove compartment of a JDM 300ZX we just imported.

 

could it be an adjustable fpr? long shot i think

 

THinking it might be a boost controller.. being that the middle port is bigger and the side are smaller one for each wastegate.. if it is its prolly a ball and spring type.. take it a part and give some pics make it faster to find out what it is.. im leaning to BC.

 

Its a boost controller, the **** up top is a dead give away. If its a fpr its terribly designed. open it up, if there is a spring and ballbearing thats a dead give away
