quest and dodge lancer both threw a belt prematurly.

i once read in a hot rod mag about a charger that snapped all ten lug nut studs when trying to do a burn out. if all that torque can snap the studs you better belive the belt wount stand a chance.

Would there possibly be a S15 HLSD in the works? I understand you are running the CUSCO, but I believe the HLSD has a better gear ratio for the application.

Monday Night, Andy and I worked til 2 a.m. @ Southern Imports to get the motor running.

When we attached the AEM EMS ECU, it started first crank with the AEM supplied base map.

I was very impressed with how simple the box is to use, and I want to thank Sean Morris for taking my phone call late at night to confirm we had the configurations setup accurately.


We still have lots of work left to be done, and these are, by no means, final images.

As you can see, there are aftermarket gauge sensors that need to be hooked up. The boost controller is not installed, the intake for the turbo still needs to be ordered, downpipe has not been fabricated, and the upper intercooler piping has not been polished.

But the motor runs, and that's a success in itself.

Yesterday, I transported the car to Texas, and will be finishing up the car here.

Once again, thanks to Andy Vaughn @ Southern Imports in Murfreesboro, TN. He, by himself, built 95% of the car that you are fixing to see. He is a amazing fabricator, engine builder, and friend. Thanks again Andy!

Here are the images and the start-up video:
