Since I am replacing all of the more visible fasteners on the engine with ARP stainless bolts, I wanted to replace the studs that Holley includes with the Low-Ram intake manifold. I carefully measured the needed length and it looked like ARP already had an intake bolt kit in that length (55mm UHL). Long story short, the ARP bolts didn't have the needed thread length to fully engage into the heads. Vic machined the shank of the bolts so they would torque down against the intake manifold.



I also finished the last bit of NiCopp plumbing for the boost control systems. There is a tube from the turbo compressor to the bottom of the wastegate. There is another tube from the compressor to the fill side of the boost solenoids. Finally, there is a line from the boost solenoids to the top of the wastegate.



For the intercooler water hoses, I am using the Earl's Super Stock hose and swivel fittings. I have never used these before, but they work awesome. The ferrule spins over the hose to give the hose end a finished look.



I used dish soap as a lubricant.



Little dab here...



Little dab there...and...



Viola!!!....oh, and Vic had already welded the fittings to the tank and mounted it with rivnuts.



We also added an EGT probe just before the turbine housing.
