So I get my car (B16 in 92 hatch) with a newly installed rev hard stage 2 turbo. Take if for a few spins and it was okay. Fourth spin, my engine stalls and there is smoke from under my hood. After we let it cool down, we can start the engine, but have to hold on the gas for it to stay on. Once the gas is released, it stalls. A technician told me that he thinks that I melted the rings and the engine can not hold the compression. Any ideas as to what has happened, what I should do and how much it would cost? Thanks.
