Engine and trans are in the car and the K member is done. The hotside that came with the car was test fit.

Unfortunately, the hotside won't work with the A2W intercooler I'm using, at least not with how I want to mount it. So out it goes.

The hotside will be redone with 2" mild steel tube I already have. I want to mount the intercooler to the front K member tube in front of the engine but behind the puller fans for the radiator.

i have the same seat cover in my Nova. really did make the ride more enjoyable, the **** recover someone did before wasnt an appealing look or feel. seems to grip better also, dont slide around as much.
love to see the dyno and street footage of your setup when its done. still havent decided what engine/turbo i am doing in my Nova, nice to see how this combo does.

Cut down a 3" cast aluminum elbow that needs to be welded to the intercooler. That way, the turbo will connect to the intercooler with one long 45* silicone coupler to allow for flex.

Got a deal on a turbosmart 50mm wategate that will go just outside the front frame horn to give the wastegate some priority before the turbo flange. It will dump in front of the front tire. Also have a VS racing BOV on order along with a Speedway double pass aluminum radiator. I didn't trust the 47 year old V6 radiator and the the double pass puts the inlet and outlet both on the passenger side which makes more sense with the LS. I hope to cut down and re-use the old radiator hose.
I'm also planning a little sloppy surprise for the rest of the cold side.

This is a cool build! So exciting that you kept the hotside diameters so small in keeping with the math/science of it all. 2 1/4" into the turbo is even smaller than I was thinking might be smallest tubing I could bring myself to use on a build sort of like this, so I can't wait to see how it works. And really nice work, BTW!

No solid dyno numbers, but it's loafed to an 11.44@117.1 on 10 psi at a featherweight 4100lbs and aero of a barn. It's all about heat delivery mang!!

I was thinking I could at least use the PVC on occasion, like at car shows to induce butthurt. I'm hoping I can run it at the track. But I agree with you, the underhood temps especially at long periods of idle after a highway blast would be the most likely problem. Other than wrapping the exhaust, I can't have much control over that.
I can put together an aluminum 3.5" OD intake with new mandrel bends for around $50 and use my existing silicone couplers which is my backup plan.

Went nice and small on the hotside. I see no reason to go over 2.5" on the cold side. I used 3" as well just for ease of install. Can't see a setup like yours benefiting at all from 3.5" piping. Some baby 2.5" piping on there would follow the "sleeper" look.
You can get a 3" alum U bend for $20 shipped, I never had an easy way to weld alum so I went with mild steel.

Forcefed86, you got me thinking. I could use the other half of the 3" cast elbow for the outlet and point it directly at the TB. That way I could do the rest of the intake tube with a single 3" 90 elbow. Thanks for your input.

In other news...I found a vintage 60's beer cooler I am going to use for the A2W ice tank mounted in the trunk. I may even thhrow a drink or two in it to pull out after a run.

I'll probably use a rule pump, either 1500 or 2000. I just saw a test with a "seaflo" which can be had even cheaper so there's another candidate. I am open to suggestions for the IC pump.
Got the idea from CameronVic's igloo cooler but I wanted to keep the period correct look when the trunk is open.

First attempt at the wastegate placement was a minor fail. Front tire hit the wastegate at full lock.

Gonna need to add a bend to the wastegate stub for clearance. But it comes off the merge pipe at a decent enough location that it should get adequate priority from the crossovers. Now I just need to make it clear the tire.

Seat cover was an ebay find: http://www.ebay.com/itm/Truck-Bench-...-/170544462994
It is a generic fit for a truck bench seat. It comes with a bunch of string to tie up the cover in sections. It looks good from ten feet lol, but its cheap and durable.
