Ok today, after following information obtained from mr2 owners club. I did the ABV modification to my 4agze.
I T-pieced the brown VSV which goes to the inlet manifold with the tube that goes from the ABV which was attached to the blue VSV (which i blocked off)
have i lost ya yet?
With that done i blocked off the other tube from Blue VSV leading to the Throttle body.
Hence nothing is attached to Blue VSV. It still has a plug on it.
Im not sure if this is right.
Anyways, i went for a spin. Didnt reallly noticed any chance at all. Still peaks at same PSI.
I know of ppl who done this mod. and achieved from 8psi to 10psi.
This is with the standard pulley.
4agze: No real difference with ABV mod?.
