This TTC (true twin conversion) mod will make the sequential turbos run in parallel instead of sequential.
basically it delays the first turbo so they both come on together.
All you need to do is move around 4 hoses to bypass the VSV and connect the pressure line directly to the actuator for both intake air and exhaust gas.
The attached pics will probably be easier to understand than my descriptions.
green and red are where the hoses are routed stock.
orange is where the hoses go for the TTC.
Step 1: bypass VSV for IACV
located at rear left side of the engine.
this part is easy just make your hoses look like this.
At the bottom middle of this pic there is a hose that goes up and bends back down to connect right beside where it came up.
that is the VSV for intake air.
pull off the longer hose and connect the shorter one to block off both side.
Step 2: bypass VSV for EGCV
located mid left side of the engine beside the intake by the MAF connector.
this one I took off the intake for more room.
I recommend buying 1 foot of hose from piston ring or somewhere for $1.00 because the stock hose is barely long enough.
same idea here but there are 2 hoses going downwards.
follow the one on the left of the pic or closer to the rear down and pull it out of the VSV.
pull the other hose out off the actuator and use it to block off both ports of the VSV.
connect the line that came down from the top to the actuator you just disconected.
Now you are finished.
