This car came to us to swap the engine for the Track Attack LS7 we recently built for it. It is a C5 chassis with C6 body. The car needed a lot more work that we originally expected and our goal was to get it done by the Nationals. The car is now ready for Nationals and below is a description of the work we did.






The car had numerous problems its first outing at the track. It was consuming a lot of oil and overheating. The engine was a 434ci L92 engine built by a well-known engine builder and it had 20 laps on it. Upon putting it on the dyno, we found it to have low oil pressure, high oil flow, high blow-by and was way down on power from advertised. We didn't want to lean on it on the dyno for fear of blowing it up. If the customer wants to, he can post the graphs I sent him on this engine. They were ugly.


The cooling system was a mess. There was no ducting. Air was blowing around the radiator and there were numerous items simply blocking the radiator. No way could this car operate on a racetrack in Arizona with this cooling system. We re-designed the cooling system and installed the oil cooler from the C6.R. We added a Dewitts radiator and custom fabricated ducting and a new airbox.


We relocated the PCM to the dash to make room for the coolant tank.








Installing engine.





We installed Moton Motorsport coil-overs



Installed Pfadt CF driveshaft, RPM diff, and fixed a lot of the plumbing. The previous shop used what looked like washing machine hose from Home Depot to insulate the lines.




No joke, this is what the previous shop used for a steering wheel spacer.



Here is some more lovely craftsmanship. Since it is a C5 frame, the C6 torque tube shifter hole didn't line up. Instead of cutting a proper hole, it looks like somebody used some vice grips to rip the metal.



And now on to the scariest part of this car. This car had numerous safety issues that have been addressed. Somebody decided it was safe to bolt the seat directly through the floor with just bolts and washers. As you can see in the photos, the holes were rounded out and one of them was even cracked. If the car were to be in a crash, I have no doubt the driver would be in the seat and ejected through the windshield. But what about the seat belt you say? Well that was another issue. It had clip in belts and the installer did not use proper mounting geometry which resulted in the hook barely grasping the eyelet rather than hooking through it. Extremely unsafe. Here are some photos of the floor.


Here is the proper seat mounting




We also installed an air jacking system on the car which is very cool.





What did we learn from this car? Send your car to Katech first. It is a lot cheaper than doing it twice and it might even save your life.



Watch out for this car at Nationals!

Oh, I almost forgot another major safety issue. The fuel pressure sensor for the racepack dash was mounted on the schroeder valve on the fuel rail. Vibrations caused it to bend the valve and almost break it off. If that were to break it would cause a fire. We relocated the sensor using a flexible hose.

you guys do great work. I'm not done yet more of $$$$$ to come your way. Katech does it right the first time.

Reminds me a great deal of what I am doing, C5, C6WC body, only doing it all myself and learning as I go, probably have half the budget as well but I am inspired by this to really build mine as good as a "grassroots" car can be

Thanks!

The parts cost just over $3000. Labor is going to depend on if your car is still a little bit of a street car or if this is a racecar.

Nice stuff, Jason.

RedLS1GTO

Looks like an awesome car

When you start talking about $3000++ jacks, you are WAY WAY out of my league.

stano

Where do you get the widebodies for these C5's?

Nice work!

I'm familiar with the car and the owner. There is a complex story behind the car and to make it right, my friend has had to leave a long trail of $$$$$ to get where he is now. Fortunately, the lessons have paid off and he will be safer and MUCH faster now. I'm going to call him and wish him the best at Nationals.

Cheers,

I didn't think a C6 body could fit on a C5.. I guess my problem is that I have a C5Z..

BrianCunningham

OMG!
WTF!



Please tell us what "shop" did that!

Katech_Zach

I think this one came from AC Products.

With enough work anything can fit.

I'm not going to mention any names and I think this car has a history of more than one shop. If the owner of the car wants to post that is up to him.
