Thanks and that sounds good. I had the old cast iron Corvette master on it prior and it worked fine. Like you, I wanted the self contained unit. Sure does clean up that side of the firewall.
Cant wait to see the vid of this thing rolling down the road!

So, I've been driving the Nova around for the past couple of weeks. Had an issue with my passenger side coil harness cutting out intermittently which resulted in a large backfire and a split open muffler. But all is good now, so I made a run up to Firestone to hit them up once again for my lifetime alignment that I purchased in 1994. I felt a little guilty, so I paid the mechanic a tip for his extra care on it. Then I stopped by a grand opening of a local Audio shop that was sponsoring a car show. It was cool to get some reactions to my project that I've been working on the past couple years. Now all I need to do is add the turbos for some real eye candy.
Here's a little idle clip from this afternoon. Seems the Magnafuel pump is the loudest thing on the car... Hopefully I'll get some video from the dragstrip soon.

Mr. I just completed reading the complete thread. It looks as if the build is going good. I also noticed a couple of things. First of all the engine plate looks just like the one that I have in my shop. I wonder where that came from? John done good on them!!!!!! Also in one of the pictures I notoced the blue hood, is that the hood that was on the car when you purchased it? It's hard to beleive that it has been so long since we went and looked at purchasing the rolling chassis. You have dome many great things with it over the years, however the turbo build appears to be the best. Good luck with the remainder of the build, and keep me posted. I want a ride once it is completed.

Over the next couple of weeks I'll be distracted from the Nova while I rebuild the T56 in my Corvette. I think I also have a clutch job on a friend's C5 to help finance my transmission parts. But I do plan to sneak out one evening and take the Nova to the dragstrip from some baseline numbers naturally aspirated.

Really cool to hear from a hot rodder in Denmark. Maybe some day I'll get the opportunity to come visit your country. Thanks for the comments Mad Max - these car forums are a great way to network and keep motivated on our projects.
I drove the Nova to the dragstrip last Friday night and made a few test passes. Remember, this is running naturally aspirated (for now) at 9:1 compression on 87 octane gas, temporarily using truck exhaust manifolds, and it has a turbo specific camshaft. I'll have to say with this setup the car just felt soft. I was able to run a best of 7.58 @ 92 mph in the 1/8 mile with a 1.74 second 60' (on slicks). That is kind of where I expected to be, but maybe hoped it would be a little quicker. My 80 lb/hr injectors are only hitting 38% duty cycle, so that is another component that is certainly not optimized for running NA. So now that I have my baseline performance it's about time to finish collecting parts for the turbo installation.

just a quick question for you, since i still have the stock frame, and will NEVER have a awesome aftermarket frame. Considereing doing my turbo setup with the 6.0 manifolds pointed down and forward like yours will be.
What issues were they with the maniflds mounted like that with the factory frame? would it be impossible? minor modification? major modification?
Thank for the help and hurry up with you turbo system!!

The truck manifolds wont fit without cutting the ends off and welding v bands on. I never went that far though, as it was before people figured out that they are weldable.

Sorry that it's been a long time since I even checked on my own build thread, much less worked on the car...
Using truck manifolds turned forward and down with a stock Nova Gen III subframe is not workable - at least in my humble opinion. The driver's side would work by cutting off the manifold 3-bolt flange and welding on a v-band:
But the passenger side manifold simply turns down too quickly and runs into the frame. I don't have a picture showing the passenger side turned down, but from my memory it would take some serious surgery to work. The best I can show is the truck manifold turned up on the passenger side.
I promise that I'll get back to work on the Nova in the next couple of weeks. I currently have a 2003 Z06 in the garage for a cam swap (my 7th C5 cam swap). But the good news is my M12 rebuild is up and running in the daily driver so now I can focus on the Nova again. The next step is to mock up an intercooler(s) and decide on air-to-air or air-to-water. I have in mind using this air-to-water installed horizontal beneath the radiator. I need to make a template to see if it what it takes to make it fit there and how it would look. Overall Size: 29"x13"x4.5"
