Long story short- Mark got his car back and blew the motor, so we're building it again. VAST is rebuilding the motor for free since it was warrantied, I'm helping Mark out by rebuilding the car again for free, and we're changing a few things about the setup this time.

It's kind of a long story as to the cause of the failure, but here are the main details:
- The cylinder heads were built like a tank
- The block was built with new OEM parts (budget bottom end)
- The Tial kit designer (whom I spoke with on the phone a number of times) was overconfident, and gave me faulty information on pre-loading the turbo waste gates, resulting in the waste gates not being able to open below 27psi, regardless of the WGDC.
- In order to get the car to run safely at that boost pressure we added fuel, added W/M injection, and tuned the timing so that there were timing correction factors of 0.5 at a maximum (which is VERY low). But all these precautions combined apparently wasn't enough to compensate for a 2:1 air compression ratio.
- Mark floored the car in 6th gear , over-loading the engine, and all that boost pressure combined with stock pistons (9.5:1 compression ratio) for too long just built up too much internal cylinder heat and pressure, and something in the block let go. I'm still ripping into it to determine what exactly exploded, but if I don't see anything externally on the motor, VAST will find the exact problem when they rebuild the engine.
- This time around we're going with a true GT kit and possibly low-compression upgraded forged pistons, as well as some smaller items.
- The car will be faster this time around

That sounds like a damn straight stand-up shop. I've read and experienced first hand built motors blowing up after a build and very rarely does the shop actually stand by their work and help the customer out.

I have to say that both Jordan and Vast are of the upmost proffesionals that I have ever delt with in the automotive industry and they both do top notch work that they are more then willing to stand behind.
