Totally agree...it is your own risk and responsibility if a motor pops trying to run that sort of power. I dont think any workshop will fix for free a popped motor down the line. I know if mine popped I wouldn't expect Ken to rebuild it. I wanted to run this power, I was warned about the potential of popping it, but with a good tune you can minimize the risk IF the motor is in good condition to start with.
Here is a list of my mods from the turbo upgrade thresd (5th post from the bottom of the page)
dont forget...if it is a totally stock car, you will need to upgrade the clutch and suspension...and get wider rubber to make use of any of the extra power. You should also look as potential brake upgrade too...
...and advanced driver training in the car once the upgrades are done to know how to handle it for when all hell breaks loose!!!
