It was also time to think about where the fill tank for the A2W intercooler might go. I am thinking about this location on the firewall. I added a 45 degree fitting to the intercooler just to see how the hoses might be routed.



The tank looks like it is close to the downpipe, but there is actually quite a bit of space. The tank also needs to have a fill bung aded to the top of the right side and an outlet on the left side.



This is just an overall shot of the engine compartment as it sits now.



Baby steps...

Andrew...you're the man!!

With this being an auto now, will you have paddle shifters or are you focusing more on drag racing with the car?

Glad you're chipping away at it. A little everyday adds up quickly.

I am using the Lokar Sport shifter that has tap up and down capability, so I can use the Manual Mode function for auto control on the Holley Dominator ECU. I may also install paddles as well.

The focus of the car is to have a reliable 10 second street car, that also handles fairly well.

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.

This morning I received the 1/2" hub centric wheel spacers that I ordered for the rear.



The fit was spot on.



I added this spacer to center the tire in the wheel wells. There is about 1.5" from the tire to the frame on the inside and about 1" on the outside. Also, both sides looked the same, which means the axle is well centered in the chassis and the body is well placed on the frame.



The Mickey Thompson ET Street SS tires look amazing! The rear end is in full droop in this picture. Ride height is still to be determined.



After the fun stuff, it was down to a rather tedious project. These are some banjo -AN adapters for the transmission cooler lines, compared to the stock adapters on the right.



See that hole at the top?



That one...That is where the longer fitting has to go, and there isn't enough room in the transmission tunnel to take the fitting out. So I had to remove the transmission crossmember and lower the trans in order to install these. This picture is with the transmission at full droop.



Here they are installed with the transmission back in place.



Then I got to looking at the intercooler and grabbed a gray scuff pad and started to rub. I really like the brushed look for the intercooler, so I will use the gray scuff pad over all of it and leave it a natural brushed finish (the rest is bead blasted for now).



A big "Thank you" to one of my customers, who graciously engraved my logo into the intake manifold plate.



She is starting to look like something!

Yeah it is!!

Sounds like you've got a great recipe going for your goals, Andrew.

It remains to be seen how tasty it will be when it is done. I am already wishing I did some things differently, but I am not changing direction at this point.

Everything's looking so damn good Drew.

So good to see this 70 GTO evolve over the years. Fantastic.
