gday. im putting my car back together after emissions removal and wastegate porting. my first question is the coolant feed comes from the intake manifold? how does the coolant get there? i have removed all my manifold bolt ons. my next question is there any advantage to removing the twin scroll? i have 2.5 inch exhast. pod filter. throttle body mod and 8psi of boost. the car is a 1988 s4 turbo jap import

 

The coolant travels through the intake manifold, there is a port that goes straight through. You will get a little more flow through the turbo if you remove the twin scroll and maybe slightly higher boost, but a slightly lower spool up time.

 

so theres a port that goes straight through from the block? and its all internal so i cant have messed with it. thanks for the help by the way

 

Thats right. No problem.
