68 twin turbo dart project.

Now on to the cooling system. I found that a radiator for a Nova is wide and not that tall. Thats good because I need to raise the radiator to clear the turbo inlets. And I also threw the hood on to see how the clearance is.

Here is the shots of the water pump and hoses.

Great to see you re-energized and making progress, Chris. Looks awesome. I'll have to swing by for a firsthand look the next time that I'm out your way.

Do it! It’ll be great to see you

Looks great. Tons of room with that small block.

Now that's some progress my friend.

Not a whole lot once you get it all in there. But you knew that already.

Now that's some progress my friend.

Hello my A body friend!

 

[turbodart68]

Hows about some more progress photos. Here is the turbo support crossmember.

Very true! I was mainly referring to the tight confines of the A-body being helped somewhat by the smaller size of the small block. Can you imagine turbo headers for an A-body Gen2 hemi? Those won’t come over the top.. lol

Here is the firewall modification. I originally welded up all the individual holes and warped the firewall requiring a ton of bodywork. Also I need a flat spot for the intercooler charge piping to come through and meet the intake elbow.

Hey is my good friend fitting up the sheetmetal. He is quite the fabricator and I am really fortunate to have him helping me on this. He is also quite the motivational force lol.

And fully welded.

 

[turbodart68]

So to do the firewall I needed to pull the engine. While it was out I put a crank in the motor and added the oil pan and balancer so we can set up the alternator.

 

[turbodart68]

Oh and by the way. That is a stock 68 block. It has a 68 VIN number on it. When I am finished with it I am going to try and find the car it belongs to.

 

[turbodart68]

We decided to run a dual fuel system. We will have a 12 gallon fuel cell for pump gas with an A1000 intank pump for pump gas and then a 7.5 gallon fuel cell (a 20 gallon cell with a divider 2/3s on one side and 1/3 on the other) for track time with an Aeromotive 3.5 Pro pump (externally mounted) for C16 race gas. It'll run through a single -12 line and have a -10 return with valves to switch between the 2.

I could imagine! I built a twin turbo Vega with a small block 10 years ago and It was stupid tight. The hard part is making it so you can work on the darn thing without having to remove 1000 things to get to what you need to fix. I kinda wish I had removed the inner fenders and mounted the turbos behind the front wheel.

Brilliant idea on the turbo crossmember mount. I'm loving the build!

Thanks man!

Time for an update.

This the shots of the intercooler and water tank. There is a bilge pump (for a boat) inside the tank to circulate ice water through the intercooler. The intercooler will be obscured by the dash. This intercooler is rated for 2500 hp or over twice what I will make.

 

[turbodart68]

This is the charge piping from the turbos to the intercooler then though the firewall to the throttle body.

 

[turbodart68]

Some more pics of the same. If there was a lesson learned it would be that aluminum moves A LOT when welded.

 

[turbodart68]

Next up is trans cooler and shifter. I decided to mount the trans cooler in the rear since I have so much stuff up front. The cooler is a Derale unit for Summit Racing. Its kinda overkill but these turbo cars make heat while building boost on the brake so I figured I would go big.

 

[turbodart68]

The alternator is a power master 75 amp unit. Hopefully it can keep up with all the electronics in this thing. Its getting really tight here and finding solutions that are easy to service are getting more challenging.

 

[turbodart68]

Test fit of the bumper. Looks like the charge piping will be hanging out. I never really cared much about this hopefully I won't catch it on a parking block.

 

[turbodart68]

This is the last for now. Its the down pipe exiting the turbo. Its 4" and its tight. Even if it was 2.5" I wouldn't have much room to fit it. So it'll be a little loud for now, maybe I will come up with something better in the future.

 

[turbodart68]

Oh and its on the ground again. So here is a taste of what it'll look like. I have 8 more items to finish and then its on to bodywork!
