Time for a new motor. With parts and labor and everything involved youre probably looking at a $2000 bill.

 

You can find good used motors from ebay or craigslist for around $300 to $500 bucks. You have access to the base hobby shop with all the tools which is a plus, just find a buddy or two to help with the install. Good luck.

 

I have read about being able to put a 2.0 vvti in it and have found one for 400$ I planned on doing all the work myself

 

Good luck doing a motor swap, its not nearly as simple with modern engines with all the electronic controls. If you were able to blow up your motor running with such major problems trying to get it to a shop, I think you might be over your head with a motor swap.
