Well as some of you my know i am doing a 88 gxl to a jdm s5 turbo swap. i have the TB mod done Rats nest removed kept the fuel lines though. Added a microtech lt-10s, xtd stage 3 clutch pulled my hair out needle bearing the motor came with a OLD HKS SSQV blow off and a knight sports double belt pulley. ok i removed every vacuum line that i could the only lines that are left go to the bov,lt-10s map sensor boost gauge, fuel regulators,turbo, and brake booster. I did notice that i did get rid of the BAC was that a bad move? alsoi did not cap the big line that goes into TB i think that is the coolant line but i cannot find a clear vacuum diagram just for tha bac if i could that is probally my leak let me know if i am answering my own question it fiannaly drives

 

I'd make a block off plate if you're not using the BAC.
